Honeywell T6 Wired Smart Thermostat – Works with Amazon Alexa


a

The Honeywell Home T6 Smart Thermostat is a next-generation, programmable thermostat made to fit your life. Take comfort in an innovative thermostat that adapts to your schedule, helps save energy, and makes your home smarter.

  • Simple to set up, straight out-of-the-box.
  • Save money on heating with adaptable, intuitive programming.
  • Energy efficient and more Earth-wise than older or more basic thermostats.
  • Full control via the thermostat’s simple touchscreen, even without the Honeywell Home App.

The T6 thermostat knows how long it takes to get your home to the right temperature, removing the guesswork and saving you money. Ask for 21 degrees at 7 a.m., no problem, the T6 works out how to get there, whatever the temperature is outside. The T6’s intelligent comfort control helps maintain the desired temperature when you need it. So your home will always be comfy and cosy, whatever the weather.

SIMPLE TOUCHSCREEN INTERFACE: The T6 touchscreen makes scheduling, changing and overriding temperatures easy with a large, clear display and intuitive on-screen text guidance. Temperature can be adjusted in 0.5 degree increments. The thermostat display is backlit all the time, providing low-level nighttime illumination and temperature display at all times. You can set the light level via the touchscreen.

TAKE CONTROL, WHEREVER YOU GO: Pair with the Honeywell Home app, which gives you complete control over your home heating. Control your thermostat via smartphone or tablet.

INTUITIVE GEOFENCING: The T6 adapts to your lifestyle using innovative geofencing technology. It knows when you’re away, helping to save energy. It also knows when you’re just around the corner — and ensures your home is at the perfect temperature when you arrive.

SAVE MONEY: The T6 offers a number of optimisation features, including “optimum start and stop” boiler control, allowing the thermostat and boiler to work more efficiently together. ERP Class 5, 3%.

SMARTER CONTROLS: Built-in TPI (Time Proportional & Integral) controls simply switch current supplied to the boiler on or off at different times. The T6’s integrated system ensures the boiler fires for the minimum amount of time required to maintain the required temperature set point, making heating your home even more efficient. The T6 also includes frost detection protection, ensuring the pipes will not freeze if the temperature dips too low.

ADJUSTABLE & ADAPTABLE: We know life is unpredictable. That’s why you can choose either 7-Day Scheduling or change things remotely if your plans change.

T6 MODEL OPTIONS: The T6 Series features three models; the wired T6 and the wireless T6R, and the T6R-HW that is wireless and also includes hot water control.

Installation Basics

Compatibility

Is the T6 suitable for my property and will it fit my heating installation? The T6 and T6R Smart Thermostats are suitable for most water-based heating systems, including combination and system boilers, either gas or oil-fired. They can also be used as part of S-plan and Y-plan system. The T6 receiver module can be used with ON/OFF boilers and it has OpenTherm capabilities offering boiler modulation. Some boilers with modulation functions have restrictions on what connections will work and therefore we recommend contacting the boiler manufacturer.

Do I need WiFi to operate my thermostat? The thermostat will work perfectly without WiFi. It is not required for setup or programming. You will need internet connection to be able to remotely control your heating system. Honeywell Home’s Connected Thermostats use a proprietary communication protocol that work on the 868Mhz band. This should not interfere with any other wireless devices. The T6 will work with any wireless 2.4 GHz router and is easy to connect to existing WiFi networks.

Installation

The T6 lets you do it yourself. Easy and fast to install, the Honeywell Home T6 offers many features to simplify setup. These include a flip-up wiring bar for easy access, clearly labelled terminals, and strain relief for simplified, secure wiring. Before installing, turn off power for safety and remove your old thermostat. Carefully review the wiring diagram included in your instruction manual.

FITTING THE RELAY BOX: This box contains connections for your power, boiler, and thermostat. Choose a suitable location near your boiler and use proper wall mountings for your wall materials.

CONNECTING THE T6 TO YOUR WALL: Once your old setup is removed, the existing cables will attach to your new T6 thermostat. Feed them through the wall panel to begin and align the wall plate. Attach the T6 thermostat face to the wall plate.

SETUP & CONFIGURATION: Once installed, the Honeywell Home T6 features an intuitive and guided setup that can be accessed from the Honeywell Home app, or the thermostat itself. Follow the prompts to begin setting up your upgraded home temperature control system.

Smarter Connection

The Honeywell Home app allows you to connect, control, and monitor your smart devices.

  • One-touch dashboard.
  • Alerts to let you know what’s happening in your home.
  • Geofencing provides location awareness to respond to your needs throughout your day.

    Golden Review Award: 5 From Our UsersSarebbe un bellissimo prodotto: touch screen reattivo, interfaccia intuitiva, elegante e pratico. La connessione wi-fi permette un controllo estremo, tanto dalla app Honeywell che da app di terze parti.
    Alexa in grado di elaborare e applicare istruzioni tipo “imposta il termostato a 21 per un’ora” e si possono creare routine per programmazioni aggiuntive rispetto alle fasce orarie massime disponibili nella app Honeywell: quest’ultima prevede fino a 6 cambi di temperatura programmabili, ma con le routine di Alexa possono diventare infiniti.
    ATTENZIONE: una sera le funzioni wi-fi del termostato mi hanno piantato in asso senza spiegazioni. Per un errore “imprevisto” ha perso la connessione e ne ho provate _di_tutte_ per farlo ripartire: reset, spegnimento e riaccensione, ripristino a valori di fabbrica, disinstallazione reinstallazione della app, reset del router, ripristino ai valori di fabbrica del router… NIENTE. Numerosi utenti online lamentano questo problema.
    Poi ho avuto l’illuminazione di cambiare il cellulare usato per la configurazione (da iOS ad Android) per ripartire con una reinstallazione da zero: ha funzionato. Che sia stato un caso o meno, per ora funziona.
    In conclusione: mettete in conto che a fronte di un bel prodotto si corre il rischio di disavventure come la mia e, nel caso, tenete presente questa presunta soluzione per poter ovviare.

    Works great, easy to use display, but of a pain to connect to the WiFi, would be better if battery option and not just hard wired. Worth the money? Not sure, it works well but does not feel quality, the thermostat display feels plasticky and poorly put together (rattles a little like it don’t fit properly)

    Really simple to install, replaced the old fixed timer no problem. You can change the program very easily from either the temperature display unit which can be positioned anywhere in the home or a simple to use App on your smart phone. Temperature can be controlled either by a daily schedule or a really clever Geofencing system which will switch the heating off when you leave the house and switch it on again as you travel home, brilliant. Also temperature can be manually adjusted if you need a quick boost.

    Really good produc

    Golden Review Award: 2 From Our UsersEl producto est genial, ya que al poder moverlo de un lado a otro (siempre ha de estar conectado) es una ventaja. Pues en mi caso al tener una casa tengo unas zonas ms fras que otras y este lo llevo all donde estoy de ese modo se que as esa zona estar a la temperatura que deseo. Es fcil de usar pues es tctil y muy intuitivo adems al poderlo controlar por el mvil da igual ios que android puedes activar o desactivar la calefaccin antes de llegar a casa si no eres de esas personas que la tiene todo el da puesta. Tambin incorpora la opcin de programado por si a la noche quieres una temperatura diferente a la del da o si no vas a estar en casa etc etc..

    Lo nico malo es que dependes de la conexin wifi entre el receptor y el termostato esto quiere decir que si el receptor lo tienes lejos ( al lado de la caldera fuera de la casa) o hay muchas paredes hasta el termostato est pierde la conexin y no puedes darle rdenes. La solucin es colocar el receptor ms cerca o en la vivienda y listo, aunque esto implica otro aparato ms en la pared con conexin elctrica.. vamos como si tuvieras el termostato de toda la vida y otro porttil ( es decir dos en vez de un solo aparato) as que si no vas a mover el termostato de sitio recomiendo el otro modelo pues te ahorras tener receptor y termostato dentro de casa.

    Love it- so much clearer than our previous one. Very easy to setup the schedule and very easy to adjust during the day with one touch on the screen. Had a little issue setting up as it would not work off my iPhone due the IOS version but tech support very helpful. The house feels warm at the right time, without spikes of heat or cold. Recommend it.

    El termostato funciona muy bien. Yo lo tengo conectado a una caldera mediante rel seco. Una cosa que me gusta mucho de los termostatos de Honeywell es que van activando la caldera a intervalos y cuando se acercan a la temperatura deseada disminuyen la duracin de las actuaciones de forma que la temperatura se alcanza suavemente sin fluctuaciones indeseadas. Creo que Honeywell le llama a sto funcin TPI.
    No le pongo cinco estrellas al termostato porque creo que la app para el telfono es mejorable. Le encuentro dos fallos principalmente:
    1 — Tiene dos modos de programacin. Por tiempos, donde puedes programar hasta 6 intervalos de tiempo con temperaturas diferentes y el Geofencing que permite programar diferentes temperaturas dependiendo de si ests cerca o lejos de casa. Sin embargo ambos modos son excluyentes o sea que no puedes definir que funcione la programacin por tiempos cuando ests en casa y otra temperatura cuando ests fuera. En modo Geofencing solamente puedes programar una temperatura cuando ests en casa, una cuando ests fuera y una por la noche. En mi caso me interesa programar diferentes temperaturas por la maana y por la tarde adems de otra temperatura inferior cuando estoy fuera lo cual no es posible con este termostato.
    2 — El Geofencing funciona bien y puedes configurar un crculo de tamao definido alrededor de casa para que la calefaccin se apague cuando sales de dicho crculo. Sin embargo el radio mnimo del crculo es de 500 metros, lo cual para mi es excesivo. Debera ser posible definir un crculo ms pequeo.
    El termostato tambin es compatible con IFTTT lo cual junto con la app Tasker permite soslayar las limitaciones anteriores y crear programaciones muy sofisticadas. Claro que para sto hay que tener ciertas habilidades informticas.
    Finalmente, decir que tambin funciona con Alexa permitiendo subir o bajar la calefaccin de grado en grado o ajustarla a una temperatura determinada con comandos tales como “Alexa, sube la temperatura de la calefaccin”, “Alexa, baja la temperatura de la calefaccin” o “Alexa, pon la calefaccin a xx grados”. Con Siri no lo he probado porque no tengo pero supongo que funcionar igual porque Alexa y Siri son aplicaciones muy parecidas.

    Nice and easy to install. I got an electrician friend to do it mainly because the location for the controller was a bit tight for space and he’d make a better job of it. Took him about 40 minutes. Overall the thermostat looks great and has a nice responsive screen. It has to be connected to the mains electricity which is the only downside really. A rechargeable one would have been better but it’s not a major complaint. It seemed to take about a week to ‘learn’ the heating characteristics of the house. That first week was a little odd with the thermostat not demanding heat when I thought it should have but after 7 or 8 days it has been fine. Works great with Alexa and the app, although that is pretty basic really. Geo-fencing not all that reliable but I put that down to the Google accuracy on my phone more than the app itself, since other geo enabled apps are unreliable too. All in all, very pleased with the purchase.

    Golden Review Award: 3 From Our UsersPurchased and installed this product to give me and my family a modern and greater control, mainly over our heating system, but water heating schedule too. The wifi thermostat totally replaces our old thermostat and improves the heating schedules massively with the ability to control and modify almost infinitely throughout the day and night, with daily events, 5/2 events, independent events, not only from the unit but from our smartphones, Google assistant and also using ifttt triggers, ie if the temperature drops below -3 outside or snows etc, it can automatically increase the temperature in the house by 2 degrees.

    Overall, I’m thoroughly impressed with the product, interface, looks, it’s flexibility and it’s performance.

    Wiring up was fun, but complicated solely by the fact my house was extended and the cabling to various devices changed colour and was unmarked, I would recommend a professional installer is used unless you have experience and confidence to install yourself as the wiring centre can be very daunting unless you know what all the wires from the boiler, immersion stat, room stat, and 3 way valves are, or you have the ability to identify these via wiring diagrams and testing.

    Golden Review Award: 2 From Our UsersAfter a little help confirming with friendly electrician what wire should go where I successfully installed the two units.
    No problems.
    However then spent many hours cursing and registering unit to my WiFi router and then HomeKit.
    But I didn’t give up googling and trying different things and did it!!
    Some top tips.

    Ensure using the latest Honeywell Home App.
    Create and connect to thermostat first through its ‘local network’.
    Also ensure one’s router can and has been set up to a put out a ‘separate’ 2.4G network.
    Also ensure Home and KeyChain is selected within iCloud when one tries to register unit with HomeKit.
    If at any time one cannot see thermostat within HomeKit inside the home it’s no doubt down to a brief disconnection to router rather than issue with thermostat. Selecting Auto-Join to one’s WiFi Network Settings seemed to solved this…
    HomeKit from outside the home required an Apple TV (4gen) or HomePod or a late iPad…

    I have to say the Honeywell App has v limited functionality but it does work..
    I haven’t sussed out if one can turn off / turn on GeoFencing and switch to Schedule (without creating a whole new Schedule again)
    I’m sure there is a way – perhaps somebody could let us know if they have sussed.

    Good luck…
    Thank you to everybody who has contributed on the internet / You Tube / below to pass on their installation tips !!

    I am surprised at all the negative reviews – I had no problem installing it after taking the time to understand what has to be done and it isn’t rocket science (I’m not an electrician but do have a good IT background).

    It works well (occasionally complains about poor strength of signal between the room stat and box on the wall (it’s not particularly far away, but there are a couple of corners and solid brick walls) , but it still has worked faultlessly for a month or two since I installed it.

    The only disappointing aspect is the location service where it can automatically turn off when you’re away from home. It does seem to work, but it can be very slow to react (perhaps a fault with the app – if returning from a trip, you need to remember to turn it on remotely if you want it to be warm when you get home as otherwise it will turn on too late if your radius is not big enough) and when using the service, you can’t set different schedules other than a daytime and night-time temperature.

    I see quite a few negative reviews about the connectivity to 2.4 and 5ghz routers. I did it without issue and it works fine. The glitch that people are suffering from is that it will not connect while the 5ghz is live on the router. 5 ghz has to be temporarily disabled to enable the connection, my experience told me that I had to disable 5ghz by connecting my laptop to the router, it has to be hard hired using Ethernet cables, it cannot be done using Wi-fi. The IP address and admin password should be written on the router. Once 5ghz is disabled set up was easy, once complete 5ghz can be reactivated. All in all I’m very satisfied with the thermostat.

    Relativamente fcil configurarlo. Cuando tienes que crear puntos de cambio, a veces es complicado y si lo que creas no es coherente, modifica o borra otros puntos. Nada que el aprendizaje de prueba y ensayo no resuelva.
    Requiere de alimentacin 220V para la unidad central y una toma de corriente para el display, pero aun as sigue siendo de instalacin fcil en cualquier punto de la casa.
    Funciona con la app Honewell Home tanto de Android como Apple, por lo que puedes configurarlo y controlarlo desde des de la pantalla, o desde el telfono (incluso fuera del entorno wifi).
    Cumple con la eficiencia, es elegante, flexible de instalar.
    Inexplicablemente no dispone de batera de apoyo para poderlo configurar sin tener que enchufarlo y si la corriente marcha, se apaga la pantalla (aunque mantiene la informacin).

    Por aprovechar la preinstalacin (evitando tapar el hueco de los cables y la consiguiente pintura), y dado lo bien acabado del producto, la caja de rels la conect en el mismo lugar del termostato antiguo y la pantalla en una zona de la sala de estar central y visible. El modelo de cable me obligaba a instalar la pantalla detrs de la TV, perdiendo acceso/visibilidad y recogiendo la influencia de la temperatura de la pantalla (de ah el motivo del cambio).

    Lo compr en 2018 (hace 2 aos). Lo uso con una caldera Ferroli del 2018 tambin compatible con OpenTherm. No me ha dado problemas en todo este tiempo, al usar el protocolo, mantiene la temperatura fija en el valor que le ponga, la caldera regula la potencia de la llama para mantener la temperatura que no oscila nada, la mantiene en su valor fija sin Offset, es decir, no corta llegado a una temperatura y arranca por debajo teniendo una oscilacin, si no que la propia caldera regula la potencia para mantener la temperatura estable.
    La enciendo y la apago con el mvil y salvo alguna vez que he tenido problemas con el servicio de fibra, nunca he perdido la conectividad con el termostato. He cambiado mvil varias veces y nunca he tenido problema.
    Producto totalmente recomendable, al menos por mi experiencia. No tengo queja.

    Golden Review Award: 3 From Our UsersInstallation on to the boiler was no problem as it was a direct replacement for the existing thermostat. The facilities are good and looking forward to making the most of them.
    Setting the unit up for WIFI took many attempts, making sure that 2.4Ghz and 5Ghz WIFI was named different, making sure it connected to the 2.4Ghz with mobile data switched off. After a few days I discovered that the thermostat needs a maximum data rate of 54Mb/s. and once I configured my router for that it connected straight away. Hope this helps frustrated users as I was.
    Now works on the phone Honeywell Home app and also with Alexa.
    Gave 4 stars because of the difficulty in making the wifi work, probably would have given 5 if it had connected straight away.

    I purchased this smart thermostat as an upgrade for our existing Honeywell programmer unit.
    It was straightforward to install & set-up using the app. Holds room temperature very accurately, without any overshoot. Also works well with Apple HomeKit.
    Overall, very satisfied with the device and would strongly recommend it as a very cost effective upgrade to a create a smart heating system.

    This smart thermostat is superb. I plugged it in, it found the boiler fairly quickly and I was able to control our new Worcester combo boiler straight away.
    The only negative thing really is connecting my phone, via the app, to the device. It took several attempts and a YouTube video to get it to work.
    Now, I can’t fault it. Very simple, very easy to use and it looks lovely in our front room.
    Love it.

    Golden Review Award: 6 From Our UsersHad this for just over a week now. It’s a good looking thermostat and does not look out of place on the shelf.

    I have not used it’s scheduler but have linked it direct to the Apple home app. This is where the real benefit is. Heating on till 10:00 in case we work from home but if we both leave the house at 8:00 then heating turns off.

    Heating turns on if we leave work, or when we get home but can also be set to come on at a time if we are already home.

    Heating is set to go off at midnight but say goodnight to Siri and heating goes off.

    I have the heating in the bedroom come on later than downstairs so linked it with a HomeKit thermometer so it turns thermostat up if the bedroom is too cold and then returns it normal when it’s warmed up just between 21:00 and 23:59 but only till you say goodnight to Siri.

    What I like most is you don’t have to use voice control and it’s very easy to operate from the home app or the Honeywell app.

    Had Honeywell’s previous version of this thermostat, this upgrade is a lot easier to setup and use. And when winter comes I can turn up the heat from my bed to keep want and set timers and schedules to keep my home comfortably warm. And intergrates with Alexa, HomeKit and Google, so you can shout at you device to turn up the heat or lower it.

    Golden Review Award: 3 From Our UsersLlevo alrededor de un ao con este termostato y estoy muy contento con l. Se puede controlar desde uno o varios dispositivos Android, registrado con una direccin de email y con la posibilidad de dar acceso para controlar desde otras cuentas. Salvo alguna desconexin muy ocasional con el servidor de Honeywell (que slo impide temporalmente acceder desde el mvil al termostato), funciona de maravilla. Se puede programar con total flexibilidad la temperatura para cada franja de hora. Se puede poner una temperatura diferente si se desea para cada franja horaria y franjas horarias diferentes para cada da.

    Se puede modificar la temperatura deseada actual y se puede especificar durante cunto tiempo hasta que vuelva a la programacin normal. Tambin se puede establecer un periodo de vacaciones (termostato desactivado) especificando el da y hora que debe reactivarse.

    El termostato se puede controlar desde el mvil y tambin desde la propia pantalla del termostato. Adems, la pantalla del termostato ofrece mucha ms informacin y flexibilidad que otros termostatos con funcionalidades similares.

    Por ltimo, tiene la funcin inteligente mediante la cual aprende cunto tiempo tarda en calentarse la casa, de forma que si se establece una hora de comienzo con una temperatura determinada, el termostato enciende antes la caldera para que a la hora establecida se haya alcanzado la temperatura seleccionada.

    Tras un ao de uso sin ningn problema, considero este termostato un gran producto y a un buen precio para lo que ofrece.

    Excellent bit of kit, very accurate control of temperature provided the correct location is used. We have weather compensated control on our boiler which when coupled with the optimum stop / start on this thermostat makes for a very efficient system. Like being able to adjust heating on iPad/mobile which is great. Works well with Apple home which is a more basic feature. Have not bothered with geofencing as it does not fit our lifestyle. Have not used Alexa.

    Golden Review Award: 3 From Our UsersI’ve been using two of these thermostats for over a year, in a dual zone setup (downstairs and upstairs) and they have been working great.

    The thermostats have a lot packed in, including the ability to schedule your heating and setup geo-fencing to automatically turn on and off your heating when you leave home. You can only use one or the other, which is a shame as it would be good to have a schedule in place but also the ability to turn off the heating if when you leave and then jump back to the schedule once home. All these controls are setup through the Honeywell Home app, although I prefer to use Apple Home once scheduling has been setup.

    These thermostats are OpenTherm compatible too, so they’ll modulate your boiler to help save on gas usage. They also have an ‘optimise’ feature, so they’ll measure how long it takes for your home to heat up, so they can start pre-heating to your desired temperature. This basically means if you set your heating to be 20c at 8am, it may turn on at 7am to start warming the house so it’s at the desired temperature by 8. It’s great for those chilly mornings!

    So the reason I’ve given this 4 stars for now, is I added an extra zone valve to my current setup after adding gas heating to our garage. I purchased an additional thermostat and setup everything. A week after however, it stopped responding in Apple HomeKit and would no longer connect to WiFi. I haven’t had any of these issues with the other two thermostats so I’m hoping this will be solved with a replacement.

    After alot of research and confusion I went with this thermostat and receiver and I am very happy with it. No stupid hubs required like with nest, hive etc

    The receiver is connected to the boiler with cable. The thermostat has a wireless connection to the boiler and also connects to the WiFi. Install and set up were easy and the operation is flawless, app, alexa, Google home all work seamlessly. Temperature is always as I have set it. I do wish it was battery powered or rechargeable to be truly wireless but still overall really good.

    Achet en remplacement d’un thermostat Honeywell de plus de 20 ans. L’installation physique ne pose pas de problme majeur. Le rglage de l’appareil au niveau des plages de chauffage sur le thermostat est dlicat, car l’explication est bien trop succincte. Un effort faire ce niveau. Elle est par contre trs facile par smartphone, lorque’on peut l’utiliser.
    En effet, la connectivit avec mon smartphone S7 Samsung sous Android 8.01 a t impossible. La connexion avec le thermostat se fait, le wifi est programm, le thermostat est sur le rseau wifi, confirm par la BOX, mais le retour sur smartphone est constamment en erreur. La consquence est qu’il n’est donc pas enregistr par Honeywell, et qu’il est donc impossible de le piloter par smartphone. Je confirme donc les avis publis sur ce problme. Honeywell doit rgler ce problme, car l’intrt est d’avoir un thermostat CONNECTE. J’ai essay avec tablette sous Android 7, impossible galement. Idem avec Android 6. Et miracle avec un S4 sous Android 5, s’est pass immdiatement.
    Le programme Honeywell Home est tout fait correct, nonobstant ce problme d’initialisation.
    En conclusion bon thermostat, mais initialisation par Honeywell bien difficile, dans mon cas.
    Je n’ai pas encore contact le support technique, d’o ma note.

    Golden Review Award: 3 From Our UsersLo tengo instalado desde hace 6 das aprox y por el momento funciona a la perfeccin.
    Interface muy intuitiva, fcil de usar desde el mismo termostato, pero ms fcil aun desde la aplicacin.

    En mi caso tengo el inalmbrico que para mis necesidades va genial, lo puedo poner donde quiera y prefiero que vaya enchufado y no tener que estar pendiente de las pilas, pues los inalmbricos con wifi y pantalla tctil las consumen rpidamente.

    LA INSTALACIN; es sencilla, bien explicado en las instrucciones, yo en mi caso como tengo la caldera en el exterior, para evitar que se moje el receptor (que es el que se ha de conectar con 2 cables a la caldera y otros 2 a una toma de corriente) lo he instalado dentro de un armario dentro de casa, aprovechando que en el armario tengo el cuadro general de luz donde he cogido la alimentacin para el receptor, para la conexin con la caldera he pasado 2 cables desde ah hasta la caldera y todo funciono a la 1.
    LA COMUNICACIN TERMOSTATO-RECEPTOR; con una distancia de unos 4 metros y receptor dentro de un armario es muy buena, sin desconexiones.

    LA CONFIGURACIN DEL TERMOSTATO; (usando Android) fue fcil hasta que llegue al punto donde se tiene que poner la contrasea del wifi, me daba fallo de conexin, lo pude solucionar gracias a que leyendo los comentarios de usuarios vi que alguien dejo un comentario de que se tiene que desconectar los datos mviles del telfono para que el termostato detecte la red wifi a la que est conectado el telfono, esto deberan ponerlo en las instrucciones.

    EL WIFI; por el momento no se ha desconectado nuca en este tiempo.

    LA TEMPERATURA; que marca el termostato es correcta comparndola con la que me marca un termmetro que tengo en el mismo sitio, marcan lo mismo.

    MI VALORACIN; por ahora es muy buena, era de esperar ya que esta marca es de las mejores en termostatos.

    Golden Review Award: 6 From Our UsersQuello dei termostai smart un mercato che sicuramente avr molto da dire. Premesso questo, il mercato ad oggi mi pare stagnante con i “soliti” prodotti in giro da anni. Ero orientato a prendere l’ecobbe4 visto che amazon l’ha inserito in listino ma ad oggi non ancora disponibile. La seconda scelta sarebbe stato il nest, con l’handicap della mancanza di homekit e del montaggio in cassetta 503 ma tanti punti di forza,ma amazon sembra li stia “liquidando” anche per l’attegiamento di chiusura da parte di google verso altri sistemi. scartato il netatmo perch non opentherm e con problemi con la scatola 503. Dopo queste valutazioni ho “scommesso” su questo prodotto grazie al black friday e alla possibilit, eventualmente, di restituirlo entro il 31 gennaio 2020. Ad oggi:
    Pro:
    installazione relativamente semplice.
    opentherm
    homekit
    google
    alexa
    sembra funzionare in opentherm con la mia caldaia Sime (devo verificare meglio) e riesco a controllare anche l’acqua sanitaria

    Contro:
    installazione nell’app un p tortuosa e necessita di “dividere” le frequenze della wifi del router rinominado la rete a 5ghz (o viceversa)

    Neutro:
    presenta alcuni artefatti nello schermo se guardato laterlamente che, nonostante la mia pignoleria, non riescono a darmi fastidio.
    manca adattatore per scatola 503 (in realt esiste ma introvabile) ma essendo il termostato lungo quanto la scatola basta tagliare un coperchio bianco fare 3 buchi (1 per i fili e due per le viti di supporto) e il gioco fatto.

    The Honeywell T6 thermostats are so easy to wire into any type of boiler installation.
    Following initial set up my customers have been able to set up on the Honeywell Home app and connect to the thermostat without any help. The app set up is so intuitive it guides the user through every step.
    I certainly wouldn’t go for anything beyond the T6 as the systems get too clever for their own good. Honeywell have a nice simple easy to use product that works.

    Golden Review Award: 2 From Our UsersPrimero de todo quiero agradecer el servicio tcnico de honeywell por la rpida contestacin va e-mail.

    La instalacin es muy sencilla, lo puede hacer cualquiera y sin problemas, solo recordar apagar la caldera y la electricidad.

    Cuando ya tenemos instalado el receptor de la pared instalado y la caldera encendida empiezan los problemas de sincronizarlo con tu dispositivo mvil.

    4 consejos para la instalacin de enlace con vuestro mv:

    1. Abrir vuestro router (no literal) su configuracin y desconectar el router inteligente. Posteriormente debemos desconectar el WiFi 5g y dejar slo operativo el 2,4g.
    2. Tener el sistema operativo al da de actualizaciones de nuestro smartphone. ( muy importante)
    3. Toda el proceso de sincronizarlo se ha de efectuar en modo avin.
    4. Debemos tener el WiFi 2,4 de nuestro hogar operativo y enlazado con nuestro smartphone y seguir el proceso de la App Honeywell Home.

    Si ya habais intentado la sincronitzacin sin xito anterior mente, ir al para to inalambrico y en ajustes hacer un reset. Posteriormente volver hacer todo el proceso desde la App.

    Espero haber sido de ayuda.

    Replaced a Honeywell crm927. Receiver wiring the same so did it myself in 10mins.

    Took nearly an hour to get the thermostat to connect to network & Honeywell. Inexplicably clunky set up routine, however once set up works perfectly and linked to Alexa skill straight away.

    A big bonus to this unit that makes it worthwhile persevering with, is that unlike thealready expensive competition you don’t need an additional expensive hub to make it work!

    After reading the reviews I was skeptical about this purchase. I needed to replace a poorly featured honeywell wireless room stat and had seen the nest and hive products but didn’t fancy the cost. This was way cheaper (particularly from amazon warehouse deals) but the promise of connection issues from previous reviews put me off. I decided to try with the option to return if it didn’t work. I’m not a technical wizard but I’m happy adjusting wifi settings on my router and have a few smart home devices already in place. For initial setup I plugged the T6R in close to the boiler so I could see that it was working without walking room to room. Setup first time to a 2.4/5GHz Virgin Media router via its own connection wizard. Controls the heating via iOS app and Alexa. Can also ask alexa to report the room temp so you know without having to look on your iOS device or T6R. Also the schedule is easy to set and adjust, and you can ask for a temperature to be “held” for a specified time. We’ve been using the device issue free for 3 weeks so far.

    Installed this product to control a combi boiler, which had an existing non-networked wireless controller. There is a wiring plan given but this was not appropriate to the already functional existing connection. I had to spend time understanding the boiler wiring and the existing system before I felt confident enough to do my own version of the wiring. Once that was sorted, I moved on to the mobile phone app download and set-up. The control unit initially output its own wifi signal in the 2.4 GHz band which my phone had to connect with. This allowed me to configure the controller, before the app went on to request my wifi code and it switched to my domestic wifi router. This stage seemed to be quite flakey, requiring the 5 GHz band of the router to be switched off and the data over mobile broadband on the phone to be suppressed before progress could be made. Connection took some time. If, say the wifi code was entered incorrectly, the whole process started again with no error message or warning, to make matters worse.

    I eventually succeeded in the set-up after which the app has worked very well, so very pleased i

    Es un termostato estupendo. Es preciso, elegante, buena calidad de materiales y con buenas caractersticas (p.e. reduccin de la luminosidad cuando no lo manipulas, etc.).
    Cosas a favor:
    – Integracin con HomeAssistant out of the box desde ltimas versiones (antes era un drama).
    – Disponibilidad de API para controlarlo.
    – El cableado es fcil y est bien explicado.
    – Las instrucciones estn claras.
    Cosas a mejorar:
    – No utiliza la misma plataforma que el resto de termostatos (TotalConnect),
    – A veces la conexin a la plataforma cloud falla (si no la necesitas no es un problema, y se suele solucionar rpido)
    – Es complicado de instalar (no tienen muy bien resuelto el proceso: primero te conectas al termostato, luego activas el 4G, en medio de la configuracin, luego te conectas a la WiFi, etc. – han de mejorar este punto y simplificarlo).
    – A nivel de SW, la versin EU tiene diferencias con la versin para la regin de USA (incomprensible).
    – Echo en falta tambin alguna funcin ms en un termostato de este importe (p.e. control de A/A).
    Resumen: Totalmente recomendable. Volvera a comprar, pero los Srs. de Honeywell tienen que mejorar algunas cosas.

    This is a great product. Turned my old boiler into a smart thermostat driven system I can control remotely. The only poor area is the lack of MI that comes with the App. There really isn’t any. Other controllers are better at that element but the controller itself is fantastic. There are some technical considerations when it comes to whether you want to install it using the simple method (acting as a switch to simply turn the power to the boiler off and on to control it versus wiring it to stop the burner but allowing the pump to continue to circulate). We started off with the more complex wiring method and then opted to change to the simple wiring as the pump ran 24 hours a day). I think if you have an existing thermostat installed it’s probably pretty easy to install this yourself but if you don’t have an existing thermostat or you are not confident with wiring – get an electrician to install it. Once installed it’s a terrific controller. Be careful to choose the right model if you want to control hot water also.

    Very impressed. Fault-free operation for nearly 1year after having it supplied with a new boiler. This has undoubtedly saved me a lot of money- my last boiler had very basic control that was too awkward to bother using much of the time. Operation with the iPhone app is so convenient the heating is only ever on when it needs to be and temperature control is easy and works perfectly. No more accidentally leaving the heating on or worrying that it isn’t on when the weather gets freezing and I’m away from home. I haven’t really needed the Geofence operation but it seems to work well. I never though a thermostat could be fun…

    Ho appena finito di installare il mio T6, ne ho apprezzato molto la precisione di costruzione e la finitura. Il montaggio delle varie parti semplice e ben descritto nei documenti forniti dalla Honeywell. Volendolo montare su una scatola 503 Ticino avevo bisogno della mascherina di adattamento ACC400, quasi impossibile da trovare (l’ho ordinata in Olanda). Il mal di pancia iniziato con la configurazione attraverso il WIFI e l’App dedicata (Honeywell Home): il processo in questo caso manca di una documentazione aggiornata ed piuttosto incerto. Ho dovuto riportare il T6 alle impostazioni di fabbrica ben cinque volte prima che il processo andasse a buon fine ed il termostato fosse riconosciuto dalla App. Le spiegazioni le ho dovute cercare sul sito americano della Honeywell. Credo che queste siano lacune importanti che la casa madre deve colmare, perch dal nome Honeywell ci si aspetta affidabilit.

    Golden Review Award: 5 From Our UsersPurchased this as a replacement for a Honeywell CM921 wireless thermostat for my combi boiler.
    Took less than 30 minutes to set up.
    Connected to Wi-Fi easily.
    App is decent (improved recently apparently).
    I cannot comment on geo-fencing as I don’t plan on using this feature yet. I have set up a scheduler for weekdays and weekends, utilising the custom set up… which is just as good as the cm921.
    Only drawback is the unit needs to be plugged in. The cm921 took batteries.

    All in all, a very good replacent.

    Trabajo con Honeywell a nivel industrial, y no esperaba poco de su rendimiento a nivel domstico. El dispositivo es fcil de instalar y a estas alturas sorprende que se pueda hacer casi todo desde el propio termostato, sin tener que tirar de mvil. Configurar la Wifi ha sido complicado por un posible error en la app, ya que en el ltimo paso no se conecta slo a la Wifi del termostato, y hay que hacerlo manualmente. La pantalla se ve bastante bien, y es relativamente fcil de manejar. Eso s, demasiados elementos en pantalla, lo que hace que sea difcil interpretar qu est pasando. Creo que la interfaz principal debera ser ms sencilla. Me hubiese gustado tener un histrico de temperaturas, ya que el dispositivo no tiene verdadera “inteligencia”. Es un termostato programable normal. Por ello, tener a mano las temperaturas durante todo el da ayudara a configurarlo mejor.

    Finally got around to installing this thermostat after trying to find how to install it. Having asked Honeywell for help all they could be bothered to say was to get an engineer to install it for me! Thanks a bunch Honeywell, really helpful!
    But no worries in the end as I must have had my stupid head on as it’s really easy and simple for a combi boiler.
    All sorted and we now have the heating controlled by Alexa as well (the whole point in doing it) and a nice modern looking thermostat. Very nice and I’d highly recommend it, and much nicer looking than the Hive at the same price (at the time of purchase).

    Golden Review Award: 4 From Our UsersHo cambiato tre termostati a casa e due in studio, sostituendoli tutti con questo modello. Li ho fatti installare dall’elettricista, perch un modulo deve essere collocato in prossimit delle valvole di zona, mentre il termostato vero e proprio rimane chiaramente nella stanza da regolare. Devo dire che il collegamento al wi-fi esistente non stato un procedimento lineare e immediato. Ci sarebbero da fare alcuni miglioramenti da parte degli sviluppatori dell’app: prima di collegare il tutto al wifi di casa occorre collegarsi con lo smartphone alla rete del termostato, che a me non compariva mai al primo colpo, per cui tentativi ripetuti e ripetuti. Trovo per che da quando li ho installati gli ambienti abbiano una temperatura pi bilanciata, sempre costante, si sta meglio proprio dal punto di vista del comfort interno, ho chiesto al mio idraulico se fosse possibile e mi ha risposto di s, perch dice che la sensibilit del termostato influisce anche sulle piccole variazioni di temperatura, a condizione che la posizione nella stanza sia corretta. Ottima la programmazione a distanza via app, l’inserimento delle date di inizio e fine vacanza (adesso che lo studio chiuso fino al 7 gennaio) facile e mi evita le antipatiche programmazioni con il conto alla rovescia etc. dei termostati precedenti.

    Golden Review Award: 3 From Our UsersCompr este termostato con la idea de disponer de una forma de programar la calefaccin desde fuera de casa, para encenderla con antelacin a la vuelta de un viaje, etc.
    El T6 cumple de sobra con esta funcin.
    Creo que el comentario resultar til a las personas que se pregunten si es posible usarlo para una instalacin de calefaccin de caldera central (comunidad de vecinos). La respuesta es que SI. El diagrama del cableado para esta instalacin no viene especficamente indicado en el manual, ya que slo se indican opciones para conectar la alimentacin elctrica con una caldera nica (de vivienda), pero es muy fcil de deducir.
    No es necesario conectar el termostato a la red WIFI para configurarlo, se puede hacer todo desde la pantalla tctil.
    La configuracin WIFI tambin es relativamente sencilla, aunque hay que tener en cuenta que en algunos mviles la configuracin da un error y se detiene (yo lo tuve que configurar con una tablet). Pero una vez terminada la configuracin, ya queda conectada a la red WIFI y se puede comunicar con el termostato via la app de HoneyWell.
    Una caracterstica reseable es el geofencing, con la que se define un radio de “exclusin”, alrededor de la vivienda, fuera del cual, si el termostato est conectado a la WIFI, y lgicamente tenemos la app de control instalada en al menos un telfono mvil, detectar cundo salimos de ese radio de accin y bajar la temperatura de control, de manera que la calefaccin se apagar. Una vez que entremos de nuevo en el permetro, se volver a activar. Todo esto automticamente, sin intervencin de nuestra parte.
    Otra caracterstica interesante es que el termostato se puede manejar desde el asistente de Google, Alexa o Siri. Personalmente lo he probado con Google Home. Una vez enlazado el dispositivo, se puede dar rdenes al asistente del tipo “apaga la calefaccin”, “pon la calefaccin a 22 grados”, etc.
    Lo mejor que se puede decir de este termostato es que, una vez configurado y programado, te olvidas de que existe.

    Excelente termostato WIFI

    This replaced a Salus iT500 that was never the same after a software upgrade. Who needs temperature settings at a 1/10 of a degree? Then the Salus started to give wide fluctuations in temperature, so after a freezing / roasting week I explored the options. This Honeywell ticked all the boxes, but make sure you have a decent router that covers 2.4GHz, most do! Or purchase a wifi extender with 2.4 and 5 GHz.
    It installed easily even though my boiler had a dedicated receiver made for the boiler Potterton/Main. I fitted the Honeywell alongside the boiler and turned the Salus receiver to manual. If I had removed the Salus receiver it would have meant blanking the hole. I set up an account with Honeywell and downloaded the software, iphone was more straightforward than Android. Linked in with Alexa and set the heating programme, easy. Geofencing works great and the heat range is very even. No hot and cold cycles now.

    Golden Review Award: 6 From Our UsersNow that that I have it up and running I like the product. However it wasn’t entirely straight forward and hopefully this will be of use to others who struggle to get the android app to complete the initial registration sequence at setup..
    After physical installation, which was pretty straight forward and the instructions are good, I installed the android app on my phone. It starts off well and seems to connect to the thermostat, but then eventually just timed out saying that it couldn’t connect and suggested that turning off mobile data on my phone could fix the problem. Tried this and didn’t work. Tried my wife’s phone, also android and it didn’t work either – same problem.. Then read a bit about only being allowed to connect to a 2.4GHz network rather than a 5GHz network so messed around with my BT router for a bit but only to confirm that it was definitely connected to 2.4Ghz.
    My solution was to use my old android phone, with different android version and also, with no SIM card fitted, just connected to my wireless network. This allowed the initial registration sequence to complete successfully and now I can use the app on my current phone no problem…..
    Who knows… either the fact my old phone is an older android or perhaps significant that there was no sim card fitted.
    I have also heard that using an Apple phone or tablet is more reliable and could be used for completing the setup and then switch back to android as required.
    Hope that is of help.
    Otherwise, the app itself looks pretty good. I haven’t tried the geofencing feature as yet.

    Works ok, was expecting it to be comparative with the Hive but just as nice looking but does the same job. App is a little basic / plain but works well.

    Golden Review Award: 34 From Our UsersThe world of ‘smart’ house heating controls is huge and confusing – and I include myself in this even though as a Marine Chief Engineer I have worked on high voltage construction vessels that would confuse military experts.

    The market seems to boil down to two types. The first type is probably the most common which is the type that simply starts and stops your boiler according to the settings along with all the other bells and whistles chucked onto it. The other type is more sophisticated and also relies upon individual radiator controls.

    Both of these do not entire work for those of us who had a dual zone plus water tank system fitted.

    There are also other issues of course. If you add up the cost of WIFI rad valves across your house one has to question the bonkers claim that these will save you money. Honestly, even after fitting this I’m 100% certain I will never get back the money I’ve spent on the miniscule fuel savings.

    I’ll digress here a bit as well. I’m a marine engineer and as such I’ve worked on VLCC steam ships in my yoof. Steam ships are basically big thermodynamic experiments that use epic amounts of fuel. We would easily burn through 150 tonnes a day, so any saving no matter how small is easily seen and useful. And this is how we do it. Turn the temperature down. No, really. What we did was open up the main steam valves fully. 100% open. This is important because throttling is really inefficient. Then we dropped the main boiler pressure down to match the turbines with the control valve fully open. This is the most efficient way of not using fuel.

    If you take a house, every time you fit a thermostatic valve you are throttling water and this is inefficient becasue in order to maintain control temperature you need a high water temperature. And heating water is a logarithmic curve. The higher the temperature the more fuel you need un an upward curve. This is why underfloor heating is efficient. A large area with water heated to 36c not the 65c for rads.

    So what I do is not throttle my rads. Instead I have turned my water temp down to 57c which is above the level required for killing legionnaires but requires significantly less fuel to maintain.

    Anyway, going back to controls I could not find anything that met my needs exactly because a there are no dual zone + water smart systems.

    What there is, is this. Becasue basically what all these smart controls come down to is a remote controlled switch and this is just that. A typcial dual zone system consists of a dual zone controller – which simply puts power onto the mechcanical thermostat at set times. This thermostat will then open up the zone valve which will send a signal to the boiler to start.

    So, if you have a dual zone system, ignore the blurb in the Honeywell instructions, because its about direct boiler control and, well you can’t do that immediately.

    What I did was install this in place of the thermostat in one zone and using the 240v feed to the controller power the hub unit – which the instructions say to mount close to the boiler and which I didn’t. I of course played around with this on my bench to make sure I had it right then temp mounted it once I figured the best way to do it. See the pictures.

    You then set your original controller to 24/7 on for the zone this is controlling. From then on, this smart controller will control the temperature to your settings which you program in. Of course if like me you have got one zone working on this then inevitably you will want to do both and that means another controller. Once I do that I’ll rewire the system and remove the original controller complete.

    Now, the only bugbear I had was setting this onto my wifi network which took me an age. The blurb is not 100% clear and I was getting frustrated. Bottom line is that you have to use your phone/tablet to log onto the Honeywell wifi – then step back using the back button. It is noted but easy to miss so read very carefully the information and carefully check your app. It does work well once you understand it.

    Anyway, once you are on line you can do the usual. Set up a calendar for on/off, geographic operation which means it will start up or stop depending how close you are to your house and of course allow manual remote control.

    A quick word about geographical operation. If like me you have a lousy mobile signal at your house you might have fitted a mobile booster that uses your internet. Which also means your location isn’t your house, so you have to go and find an actual signal close to your gaff to set that up.

    Once fitted its a neat system that is easy to use looks smart and allows excellent control.

    Golden Review Award: 7 From Our UsersDopo una ricerca sia in internet che in negozi di elettroforniture professionali ho optato per questo termostato per diversi motivi tra cui il costo pi contenuto rispetto ad altri (anche se messo nel carrello la mattine ordinato la sera ho trovato un avviso di aggiornamento prezzo +20 euro) ma in altri siti costava comunque di piu, poi altro motivo della mia scelta stato per il fatto che il termostato funzionasse in wireless con relativa centralina con rel (NC NA) e che si collegasse al wifi di casa senza dover inserire sim GSM. E poi anche per le diverse funzioni oltre la gestione remota.
    Arrivata in tempi brevissimi, appena apro il pacco Amazon noto che sono stati rimessi i sigilli alla confezione, apro la confezione e trovo il termostato integro ma impolverato, mentre il manuale era sigillato cos come l’alimentatore. La cosa sinceramente mi ha un po’ seccato ma purtroppo vista la necessit di installarlo immediatamente perch l’indomani avevo il collaudo della caldaia a biomassa l’ho accesso e sembra funzionare perfettamente.
    L’installazione abbastanza semplice ci vogliono 10 minuti senza aprire nemmeno il manuale, basta scaricare l’applicazione e seguire i passaggi descritti sullo schermo dello smartphone. Consiglio di disattivare la rete dati durante la configurazione. Lapp e la sua icona sono state aggiornate rispetto alla versioni precedenti e risulta molto intuitiva e semplice da usare.
    A parte la confezione risigillata motivo delle 4 stelle, sono molto soddisfatto e mi sento di consigliarlo vivamente

    This connected thermostat generally works well. Had a few problems initially with losing connection to the wifi an reporting as offline, which was a pain as this meant it could not be controlled remotely (the main reason for purchasing it). The recent app update seems to have resolved this issue. Fairly easy to wire up, if you have your boiler wiring instructions, and set up is straightforward.

    However they onbiously want to to get someone else in to setup, instructions are very simplistic and then they just show you a very complicated circuit diagram as one of the easy steps. It did not even come with the wire to connect the two parts of the kit they supplied.

    Golden Review Award: 4 From Our UsersI really like it. The temperature appears to be accurate and it doesn’t cause the boiler to switch on/off when the temperature is hovering around the cut off temperature. I’ve used the remote control (on Android) a couple of times to turn the temperature up before we get home – connection can sometimes take a few seconds – but it has always worked.

    Took me a while to realise that it DOES NOT work on the 5g wireless (in the instructions if you read them!! 🙂 ). Once I had got that sorted it connected relatively quickly.

    I’ve managed to connect to Alexa (“what is the current temperature”, “change the temperature to 18 degrees” etc).

    I do seem to get notifications from Lyric (on my Android) about twice a week saying “we cannot connect to you thermostat” which I assume is when my router looses Internet… bit frustrating and I don’t seem to be able to turn it off.

    Overall – if you want this level of control – Its worth it.

    Golden Review Award: 3 From Our UsersEl dispositivo est muy bien, aunque tiene algn pero.
    A quien pueda interesar colocar en una vivienda con calefaccin central, pero que cada vivienda disponga de termostato individual para encender los radiadores, le digo que se puede instalar fcilmente, no le servir para poner ms temperatura de la que mande la caldera, puesto que sta se enciende automticamente y desde nuestro termostato no podemos controlar ni el encendido de la caldera ni su temperatura, ya que est tarada a lo que marque nuestro mantenedor de caldera de comunidad, pero si podemos controlar las horas/das de encendido y la temperatura que est por debajo de lo que tenga tarada nuestra caldera comunitaria.
    En mi caso instal el modelo cableado, solo hay que disponer de corriente de 220 v conectando en Tierra(verde/amarillo), Neutro(azul) y Live o Line(marron) en la caja/receptor,de color blanca.
    Despus los cables T1 y T2 del dispositivo y del receptor conectarlos respectivamente de la caja/receptor al dispositivo con dos cables, preferiblemente de colores distintos a los mencionados para no confundirlos con los otros.
    Por ltimo los dos cables que queden tras haber quitado nuestro viejo termostato, conectarlos a las conexiones de la caja receptor, en las conexiones A y B respectivamente, el orden no es importante ya que esto solo hace de interruptor.
    Y ya est.

    Funciona bien, pero la configuracin de las horas de arranque puede ser un poco liosa si deseamos modificar las horas preestablecidas, por ejemplo si deseamos que est encendida la calefacc despus de las 23: 50 , debemos primero modificar el horario de madrugada del da siguiente, para que nos guarde la configuracin.
    Creo que en este aspecto sera mejor que no viniera configurado, tard un tiempo en dar con la solucin, para que quedara encendido hasta la 01:00

    Por lo dems bien, de la conectividad wifi no puedo opinar pues de momento no dispongo de internet en esta vivienda por lo que solo lo uso con temporizador, pero si recomiendo su compra.
    Lo compr para poder ver bien la pantalla a distancia, otros modelos tienen pantalla LCD pero es pequea y no tiene el contraste de este dispositivo y adems es tctil.

    Nous pouvons a tout moment stopper et rallumer le chauffage qui contrairement a avant, si on oubliais d’teindre le chauffage il fallait revenir a la maison mais surtout on ne pouvais pas vrifier instantanment si le chauffage est ON ou OFF.

    Il a un mode geofencing qui permet de vous localiser et d’allumer le chauffage quand vos tlphone sont a la maison ! Petit problme la golocalisation sur tlphone demande beaucoup de batterie, c’est pourquoi je l’utilise uniquement en manuel

    Vous savez tout je le recommande viveme

    Now we finally got it working we absolutely love it, we had issues connecting it to our WiFi initially, when you register your account make sure you verify your email address in the email they send you otherwise you will have problems, once we done that it has been brilliant ever since. We did email Honeywell about not being able to connect but they never got back to us so their customer support is no good.

    Golden Review Award: 2 From Our UsersThis is a lovley looking device let alone everything else – it took me a whiLE to choose the right make – I wanted one not just compatible with Alexa or works with Alexa. I wanted one that worked directly with my Echo set up which starts with the Echo Plus.
    This device works with it and of course req some set up with no extar outlay for a hub device.
    The phone app needs installing and the Amazon skill to make everything work together which is now does and its marvelous.
    Being able to set a routine on yoru phone and any temp – ytrun on or off if you are out is great.
    Being able to say simply Alexa set temp 20 degrees and it does it is amazing to me as my smart home gradually grows.

    The room thermostat req a socket to power unlike my previous device what ran on a couple of batteries – which means find a spot to place this in your home rather than in the hall out of site most of the time.
    Main reason for buying this then its its design and touchscreen and the fact that in bed you can simply ask Alexa to put th eheating on when you wake up before getting out of bed.

    The set up was a bit fiddly as usual with this kind of thing – its says do this and it doesn’t work – you do something else and it does.
    Its able to set up all manner of routines – I just think its the smartest looking out of a bunch of boring looking ones myself.

    Def works with the Echo Plus and phone (req) or just th ephone if Alexa isnt part of your needs.
    Alexa was the reason I got this and the more devices that work directly it the easier this will all get…

    Golden Review Award: 22 From Our UsersIl prodotto conforme alle descrizioni, funziona perfettamente, ottime le funzioni dell’app Lyric come controllo remoto (istantaneo), il sistema di valutazione automatica dei bisogni termici Geofence basato sull’area geografica scelta e la posizione dell’utente. Nel mio caso sostituisce vecchio sistema Honeywell non WiFi.
    Il termostato da tavolo ha un bel design, un sistema touchscreen molto reattivo, interfaccia chiara e semplice, in standby risulta essenziale. Purtroppo per per funzionare va alimentato alla rete elettrica, motivo principale delle 4 stelline su 5: non avevo colto questo aspetto dalle descrizioni e pensavo fosse alimentato a batterie come altri prodotti della stessa marca e di marche concorrenti. Sebbene risulti quindi pi scomodo da spostare nei vari ambienti, una volta alimentato si avvia e sincronizza in pochi secondi.
    L’installazione e la configurazione sono state eseguite in completa autonomia seguendo la guida, in meno di mezz’ora. Qualche difficolt nel set-up della connessione tra app Lyric e termostato, ripetuto tre volte fino a compimento. Anche il rel ha un bel design pulito con chiare indicazioni LED e un unico tasto per l’accensione manuale del riscaldamento, necessita di almeno due punti di ancoraggio a muro.
    Il sistema supporta purtroppo solo connessioni WIFI a 2,4 GHz, ottima la portata radio (nel mio caso > 10 metri, tre pareti intercalari).

    Ottimo prodotto ma alimentato con cavo!

    I paid someone to install this, but once up and running it’s great. You can use Siri or Alexa to control this quickly and easily and I use it all the time when out of the house to turn up the heating before I get home. Although you can use the unit direct, I’ve found myself doing with the phone as it’s quicker and easier – the shape of things to come? It may save you money on heating bills, but I tend to override the learning and turn up when I’m cold!

    Decent value for what it is, and once set up does the job well. Factor in another 50 or so to have fitted if it’s not something you will do yourself though!

    Golden Review Award: 2 From Our UsersThis review is for the T6R (R = Radio) internet enabled thermostat which works very well with Apple HomeKit (apparently – not tried it) and Amazon Alexa (tried it for a short time, as I don’t use the service usually). As another reviewer has pointed out, this is useful if you have both an Apple and Android fan in the house – but then again, you can get the Nest app (and the Lyric app) for both platforms anyway.

    Unlike the Nest, probably it’s nearest competitor (though, recently the pricing was about equal for a time, with the Nest being on deep discount for the festive period) it is a bit more traditionally styled, and you don’t have to pay 25 for a stand with the Honeywell – it’s included. Although, cheaper 3rd party stands are available for the Nest of course. In terms of LCD display, this is far simpler than both the Nest and the Hive – though some might like that.

    Installation will grind to a halt if you have a traditional boiler setup with a tank – unlike the others, this thermostat suits a combi boiler only – no Hot Water circuit – this is probably it’s biggest downfall for me.

    The T6 (non-R) version is useful for those situations where, unlike the Nest or Hive, or many of the others, you don’t want to have to install the wireless unit just for the sake of it – many a time fitting Nest I would have been much happier to have had a unit that could connect directly to the L, Ls and N wires on the existing thermostat. Bear in mind that, yes, a Neutral wire is required, but I find most 90s houses have them, as many thermostats went ‘Electronic’ around then (not in a Bob Dylan way) and for the first time required a N for the electronic circuitry and relay. Recently, battery powered thermostats or clockstats have been all the rage – but I find most housebuilders still include the 3rd wire, now unused, at the thermostat point.

    But anyway – that’s the good bit about the wireless version, you mount the wireless bit hidden away next to the boiler with full access to all the wires you need, and either re-use the old stat wires for low voltage power to the display, or use the provided transformer for having it on the stand.

    Beware the slightly confusing ‘first time setup’ – and be prepared to deep deep on the internet for the information to do a full reset – but once installed, I’ve had this for nearly 6 months without issue. The best bit is – you wouldn’t even (need to) know it’s connected to the internet. Technophobe Friendly Certified 🙂

    Works perfectly with Alexa and Apple Homekit. I was worried you’d only be able to use one or the other but we use both very easily.
    We previously had a Honeywell CR927 connected to our combi boiler and did the installation ourselves. It was easy to DIY install, as simple as removing a few screws, swapping wires, then tightening back up.

    Golden Review Award: 52 From Our UsersPossesseur de ce thermostat Honeywell depuis le mois de septembre, je peux faire un premier bilan de son utilisation.

    J’ai la version “sans fil” qui a remplac un ancien thermostat sans fil (mais non connect) galement de la mme marque.

    Premire (grosse) dception, le module doit imprativement tre branch sur le secteur pour fonctionner. Navement, je pensais qu’il disposerait d’une batterie permettant quelques heures de parfaite autonomie (bien conscient que la connection wifi soit consommatrice d’nergie). Cette caractristique est contraignante puisque le thermostat est amen tre dplac dans plusieurs pices (c’est normalement le but d’un sans fil) par exemple lorsque nous faisons du feu dans le sjour…

    Cet inconvnient est toutefois compens par le fait que toute la configuration reste bien acquise mme dbranch puis rebranch (encore heureux).

    Au niveau de l’installation, j’ai aussi un peu galr la premire fois, et ai jongl entre mon iPad et mon smarphone sous Android pour arriver mes fins.

    Point de vue utilisation, il fait bien le job, et l’accs distance est un vrai plus: dmarrer ou couper le chauffage quand on a oubli de le faire la maison. Je n’utilise par contre pas la golocalisation. Gros point positif galement pour la programmation beaucoup plus ‘user friendly’ grce l’application. Mon pouse qui fait des horaires irrguliers apprcie que l’on puisse facilement anticiper le dmarrage du chauffage le matin sans passer 10 minutes dans d’obscurs menus.

    Dernier point enfin, Honeywell met en avant l’anticipation de son systme par rapport aux prvisions mto. En clair, l’IA apprendrait combien de minutes sont ncessaires pour chauffer la maison, et pourrait dmarrer plus tt la chauffe si la mto annonce des tempratures plus froides.
    Dans les faits, ce systme ne m’a pas paru trs convaincants, moins que les tempratures n’aient pas assez varies pour que je remarque une relle anticipation. A suivre sans doute.

    Golden Review Award: 2 From Our UsersThis Honeywell thermostat is my first smart thermostat. I could not install it myself and it was installed by a professional plumber to our 8-year-old Vaillant boiler. The main unit which displays information and controls the thermostat is well designed and the screen works well. The touchscreen can be a little fiddly, though. I can control the thermostat using my Home Kit app on the iPhone. This is very convenient and I have set various timers. This was arguably one of the highlights of this product, at least for my needs.

    Golden Review Award: 101 From Our UsersThis Internet enabled thermostat has many great features but two key ones are:

    + Works with both Apple HomeKit and Amazon Alexa. (Great for families with both Apple and Android devices.)
    + Can be fully programmed and controlled directly via the thermostat touchscreen or via the Lyric App.

    Another great feature, which is as a result of the second key point, is the unit will remain fully functional as a programable thermostat even without an Internet or Wi-Fi connection. Few other units can say the same, especially many of the other popular models on the market.

    The unit is an ideal replacement for those with a combination boiler and can eliminate the current time clock and directly replace the current thermostat. However, even those with a fully pumped system (valves control if the boiler heats the radiators or the hot water in a cylinder) may appreciate this unit if they are just replacing a thermostat and don’t need to control the hot water separately (still controlled by an existing time clock). This was my situation partly driven by my wife wanting to be in full control of the heating but not having to rely on an App. Those who have technophobes in the family will appreciate this point!

    Wiring up any thermostat is not a simple task unless you are competent or employ a electrical or heating engineer. Although on the face of it this Honeywell looks complicated it is reasonably straight forward if you know what you are doing. I have added a image of how I connected my unit and this may assist others in installing their own unit. Providing your current thermostat has three wires (must include a Neutral wire) then replacing the existing thermostat with the provided control box is easy, especially if you opted for the T6r wireless version. If the wired regular T6 then you will need a bit more work to run some extra connections but again this is not too difficult, especially when the thermostat is wired to a wiring centre. Honeywell supply additional wiring diagrams on their website which may prove useful.

    Once installed and powered up the setup process, using the App (on a phone or tablet), is quite simple and I had it configured with my desired switching times and temperatures quite soon. I noticed not long after it was setup a firmware update was pushed to the thermostat via the Internet, so it is nice to see updates are automatic. I did not try but I think you could make the setup only via the thermostat touchscreen but of course without any Internet or Wi-Fi setup included.

    Once I showed my wife how to use it via the touchscreen she actually commented as how it seemed better to use and see what was going on than our old programmable thermostat. I then added the Lyric App to her Android phone and showed how simple it was to use. She said she would probably not use it but a few weeks later she was out and wanted to check she had turned the heating down after she went out so used the App and confirmed the setting! Now she is a convert to Internet enabled thermostats!

    We also like the fact the thermostat display is backlit all the time and have found it provides great low level nighttime illumination in the hall to prevent accidents in the dark (you can set the light level via the touchscreen). The icing on the cake has been that the temperature regulation has been far better than the old thermostat, which of course is the primary function of the unit.

    Overall the Lyric T6 has provided all the features I wanted and would recommended it to anyone. Just be sure to read all the literature available to ensure you know it will work with your current system and you have the skills to fit or employ someone who does.

    5.0 out of 5 stars Excellent temperature control and provides the best of both worlds!

    Golden Review Award: 8 From Our UsersVery happy with this, once set up. The thermostat is very stable so the temperature doesn’t fluctuate and the gas combi boiler (furnace) doesn’t cycle. It’s very easy to adjust the temperature, time and schedule at the stat, it looks nice so even without the integration it’s price isn’t out of line with a top of the range central heating controller. Getting the stat online was easy following the prompts from the stat and the app. Getting online to Honeywell was more problematic. I could see the stat was connected to my router but the connection to Honeywell kept failing with a “telemetry error” I phoned the helpline using the number on the website not the US 1-800 the error messages prompted me to do. After 48 hours I got an email from support telling me to factory reset the stat, but whatever Honeywell had done had cleared the problem and I was able to connect the two mobile phones in the house (Samung A5 and MOTO G) to it. The app has been very stable and the geolocation works very nicely. Make sure you have a note of the MAC address in case you need to speak to Honeywell. There was no sticker on the side of mine as the help desk informed there should be, I got it from the router.
    I am planning to integrate my Lyric with Smartthings, probably with the Samsung controller.

    Great little unit however connecting the unit with the app is a nightmare. Customer services answer is to keep logging in and out, works in the end but not what you expect.
    Time will tell but having updated from an old, on or off thermostat this should hopefully pay for itself and no more coming home to a cold house.

    Golden Review Award: 14 From Our UsersThe Honeywell Lyric is one of a new breed of Smart Thermostats that allows you to connect your heating system to the internet so you can control it from your smartphone. This useful for a number of reasons such as:
    a) its easier to adjust your controller. You don’t have to climb into a cupboard and fiddle around with tiny switches in the dark to change the preset programme. You can save money on heating as a result.
    b) can be operated remotely even away from home. Handy if you suddenly get the afternoon off and you can boost the heating before you get home so you don’t arrive to an igloo.
    c) extra peace of mind while you’re away on your winter sun holiday. You can check the temperature of your home while you’re overseas and make sure the pipes aren’t freezing by selecting holiday mode.
    I’ve tried the Hive2 as well as Drayton MiGenie smart controllers and both have pros and cons. So how does the Honeywell compare? First up Honeywell are an established name in the heating business. My old analogue thermostat and heating controller was a Honeywell which operated faultlessly for years. The Honeywell Lyric comes in 2 versions – the T6 which has a permanently fixed, wired thermostat and the T6R which has a wireless thermostat that you can move around the house (still needs to be plugged into a power source though). The wireless is about 20 pounds or so more expensive. The first thing to note is the Lyric T6 and T6R only turn your heating system off and on. They don’t do heating and hot water – so its only suitable for a combi-boiler system really (I’m no heating engineer so there may be other instances where it does work). Given that combi boilers are often used in smaller homes I’m not sure a wireless thermostat is really that necessary but you might find it useful in your own setup. Price wise it compares well with the others on the market.
    Its relatively easy to install – if you know what you are doing you can easily replace it yourself or better yet get your heating engineer to do it. The plastic box replaces you’re old controller and the thermostat is either wired and fixed to the wall or plugged in and freestanding.
    The app is good and easy to operate. The major pros of this system are : works with Alexa and Apple Home Kit. Has geofencing (so your heating can turn on automatically when your smartphone tells it you are close to home), and works with opentherm (new boiler standard).
    All in all its a great piece of kit, just make sure that it will do what you want it to and that it is compatible with your system.

    An excellent piece of kit that works flawlessly unless t’internet goes down and renders it useless. This is fine if you’re a Vulcan with Spock’s mind control ability, but then again you wouldn’t need this device then…. All in all a well designed and quality Honeywell product that rivals some of the bigger RF Heating controller names in the market like Nest and it works with both Android and Apple!

    Once installed, the touch screen is very simple and easy to use, it responds well and the numbers are big and clear which again makes this very attractive, as it is so intuitive.

    The fact that paired with your phone you can control your home temperature anywhere this is just brilliant, what a great idea that is especially in the cold winter months.

    Golden Review Award: 5 From Our UsersThis Wi-Fi enabled heating controller and thermostat is not a like-for-like replacement for an old-fashioned controller and thermostat. Which is not to say it can’t replace the older controllers, but the thermostat does not operate on 230V (it just needs a 2-wire 20V feed from the main controller), and wiring it into an existing heating and hot-water zone valve system is not trivial, mainly because the old zone-valve system is so complicated. So you must use an electrician to fit this new one.

    If you put the need for separate water heating to one side, the wiring is actually very straightforward. Assuming you have a three-wire feed from the boiler, the live and neutral go to the live and neutral of the controller, and the switched wire (the one that energises the boiler) goes to one of the switched connectors. You need a short jump-lead to connect the live side to the switch centre pin. And the 20V circuit to the thermostat is completely separate, and ideally shouldn’t use the cabling your old 230V thermostat used, or should at least be clearly labelled as low-voltage. There are various circuit diagrams included, including one for wiring up to a zone valve, but that also needs a separate timer for your water (this assumes you have a hot water tank, which I do).

    Anyway, wiring apart, I found the setup a bit fiddly. You need to connect your new thermostat system to your home WiFi (2.4GHz – it doesn’t work with 5GHz), and you need to install an app on your smartphone and create an account to use the full capabilities of the thermostat. There seems to be a lot of configuring to do (I had to leave the app twice to connect my smartphone to the thermostat’s WiFi), but once you’ve completed that part, it’s fairly straightforward to complete the rest of the set up, which is choosing your preferences.

    The white main unit, which will probably be in your airing cupboard if that’s where the old control unit was situated, has a light to show it’s connected and a button with a light on it to allow you to override the thermostat, and turn the heating on and off. This is presumably your failsafe in case of computer failure.

    The grey/black thermostat (which will hopefully be installed in your living room) has a touch-screen display, showing the time (little numbers) and the temperature (big numbers). When you touch the display, all the options light up. There’s an intuitive +/- to set a new override temperature, a schedule enable/disable, an on/off button to disable the heating completely, and an options menu that does lots of things, most of which aren’t very interesting (you can set the idle display brightness and lock the controls, for example).

    You really need the Lyric app on your smartphone to do the fancy stuff. You can set up daily schedules (with preferred daytime and night-time temperatures) or a schedule that’s different at weekends. Or you can set up geofencing, which means that the app detects when you’re away from home and turns the heating down, but then turns it back up again when you’re on your way back home. Because it uses your location, this does use up your smartphone battery somewhat. You can also set the dates of your holidays, so you don’t need to remember to turn the heating down. And yes, you can turn your heating up and down remotely, should you feel the need.

    You can add additional users, so the other people in your home won’t get cold when you’re away, assuming they all have a smartphone.

    The whole thing is not completely intuitive – that’s a payoff you make for having the flexibility to use geofencing or a schedule. But it’s not as scary as I’d though it would be.

    Having a “smart” device heating your home, even one that’s fairly straightforward, is a big step. It gives you a lot more flexibility and makes the heating much more controllable. On the other hand, do I want my heating remotely controllable via Honeywell’s control centre? I was bombarded with automated messages to my app one night saying they couldn’t communicate with the thermostat. Perhaps my ISP was working on my internet connection, but the thermostat seemed to be working fine.

    There’s a risk from installing computers to run every part of your life. What if they go wrong? On the other hand, computers are what makes life so easy. Most of us are willing to take that risk. And a touch-screen thermostat is a lovely thing!

    Golden Review Award: 4 From Our UsersThe T6R (wireless) was easy to install. There are some really well made and easy to follow instructions provided and you can go on YouTube or Honeywell’s site for even more if needed… I was replacing a Salus RT500RF wireless thermostat and it took about 10 minutes (and only took that long because I’m not a professional and was being careful). If you really don’t feel confident and you need a heating engineer or electrician then this should really cost you no more than a basic callout charge – if it does you’re being ripped off. I don’t know if the wired/wall-mounted version is more complicated.

    I read some reviews that suggest it’s not flexible enough with scheduling – I have to disagree… you can set up a schedule, with up to 6 changepoints per day, either the same every day, or a 5/2 split (i.e. different for weekday and weekend), or by individual day – I can’t see what’s missing there. It’s more than the Salus had.

    There’s a certain retro look to the display which might not be to everyone’s tastes, or the fact it’s monochrome. But personally I find it quite stylish – and at least it’s incredibly clear to read. The touch screen controls work well and are reasonably intuitive.

    The device comes into its own when used in conjunction with a smartphone, allowing even more intuitive controls both at and away from home. And with connected home technology like Amazon Echo (Alexa) and Apple HomeKit (Siri) you can control the heating from your iOS Control Centre (the “pull-up menu”) or by voice control. Geofencing means you can have the heating automatically switch off when you’re away from home, reducing your energy bill, or warm the house up when you’re on your way home. (And you can link everyone’s smartphone, so you’re not leaving your partner in the cold). Obviously those who commute further from home might see more of a benefit than people who work, say, 5 minutes drive away. But it’s a cool feature of many smarthome devices.

    If there’s a negative, it’s only that, as with any single zone system thermostat, you can have a dilemma where to put it. The battery-powered Salus was easier to move round the house, whereas the Lyric needs unplugging from a mains socket and plugging back elsewhere – so a little bit less flexible in that sense. But once you find the right spot for it, it’s not unattractive – a smart bit of kit in more ways than one.

    It’s good enough that after seeing it in operation, my dad immediately ordered one too. I’ve just moved home and the only reason I’m not planning to get the same is because I’m now looking at getting a multi-zone system and one that controls the hot water.

    Golden Review Award: 21 From Our UsersI got this thermostat as it was Apple HomeKit certified. After reading some of the reviews I was a little concerned that it might be a little complicated to install, truth is it isn’t. The instructions tell you to get a certified electrician/installer to do the job, however I managed to install the thing in about an hour. Once installed you can either operate the thermostat from the touchscreen which is nice and responsive, or download the app on to your phone/tablet, both work great. I really like the fact the screen is constantly illuminated. My only tip from an Apple point of view, when you are going through the configuration of the app, you are prompted for a thermostat name e.g. thermostat, lyric thermostat, etc when I initially selected one of the defaults when it come to using Siri it had problems, so I just changed the name of the thermostat to heating and Siri works great with it. So far I can only tell you the thermostat has operated perfectly and lived up to all expectations.

    Le funzionalit sono quelle classiche di qualsiasi termostato intelligente, forse manca il supporto ad una programmazione multipla che permette di effettuare pi programmazioni per uno stesso periodo.
    Non se ne sente per la mancanza in quanto dall’app o stesso dall’interfaccia touchscreen del lyric si possono fare tutte le operazioni di modifica con una semplicit assoluta.
    Il termostato funziona bene cos come l’app, non ho riscontrato alcun tipo di problema se non qualche piccolo intoppo con la prima sincronizzazione app-termostato.
    Anche qui, non potendo effettuare la sincronizzazione classica il termostato mi ha proposto una soluzione alternativa che ha funzionato egregiamente.
    L’installazione semplicissima, basta avere poche conoscenze elettriche di base e si installa in minuti.
    La confezione si presenta molto ben curata, purtroppo quello che manca, come per tutti i prodotti Honeywell sono delle istruzioni complete ed esaustive.
    Alla fine una pecca che non pregiudica l’utilizzo in quanto comunque di immediato apprendimento.
    Direi che tra tutti i termostati in commercio solo il Nest di terza generazione superiore(solo come funzioni di apprendimento) mentre gli altri si equivalgono o sono un pelino sotto come funzionalit ma se si vuole avere un prodotto onesto con una app che permette di gestire il tutto con facilit e precisione direi che questo fa al caso vostro.

    Ho acquistato lil Lyric T6 un mese fa. Volevo un prodotto collegato al wi-fi e gestibile con app che per avesse la possibilit di una programmazione giornaliera, perch non sempre ho bisogno che il riscaldamento parta quando sono in casa, preferisco che parta in determinati orari o, in situazioni particolari, manualmente. Il Liryc molto semplice da installare, da connettere al wi-fi e da utilizzare. Il ricevitore montato in cucina (vicino alla caldaia, collegato alla rete elettrica), mentre il crono si trova in soggiorno al posto di quello precedente; collegato con solo i due fili di quest’ultimo non ho dovuto far passare altri cavi. Si pu programmare giornalmente, su settimana 5+2 oppure si pu impostare con geofinding per l’attivazione con la geolocalizzazione dell’iPhone. Ho provato anche quest’ultima opzione, che funziona correttamente, ma come detto preferisco la programmazione 5+2, che pu essere fatta liberamente secondo le proprie esigenze con 6 intervalli giornalieri ( ne uso 5 da Lu-Ve e 4/6 Sa-Do). Ottimo prodotto, molto versatile e per il momento senza problemi (solo una sera si era impiantato su una temperatura fissa e ho dovuto resettarlo, ma in giornata avevo dovuto staccare la corrente e quindi il wi-fi 2/3 volte per lavori in casa e magari questo ha influito). Le impostazioni in casa o a distanza con smartphone le recepisce senza problemi. Qualche volta fa fatica l’app a connettersi al server, ma basta uscire dalla stessa e riprovare per ristabilire la connessione (solitamente gi al secondo tentativo). Peccato che l’app non abbia un contatore delle ore di funzionamento della caldaia per verificare quali impostazioni sono pi economiche (speriamo in un aggiornamento). Assolutamente consigliato a chi vuole avere la possibilit di gestire il riscaldamento anche in mobilit. Se capita un cambiamento di programma al rientro di un week end fuori citt o anche solo di una serata, si pu spostare l’orario di avvio della temperatura comfort di qualche ora per ottenere un risparmio o per scaldare prima la casa.

For this version there are full detailed instructions for installing the box, including several alternatives depending on the type of boiler used. My best advice is to have it installed, or at least checked by, an experienced electrician in all cases.

    There are two units – the thermostat itself plus the receiver unit, which connect with each other via your existing home WiFi. The system in turn is controlled via your smartphone after downloading the appropriate app.

    The display unit is a 9 x 9cm black box with easy to read display, which I don’t find particularly attractive on the wall. Most thermostat units I’ve had and seen in homes are a little more subtle in appearance than this one.

    I found it easy to navigate around the app though, with all of the controls and settings required for day to day living. In its simplest form the unit will turn the heating on at the exact time required while you are on the way home. All of the expected features are there, such as seven day programming, weekday/weekend programs, plus single day programming with up to six settings.

    In essence it’s not a great deal different in functionality to the Worcester ‘Wave’ or the British Gas ‘Hive’ units except that it’s currently available at lower cost than these. However, if you are thinking of replacing your gas central heating boiler it will probably be possible to negotiate a competitive price for an internet control system from the appropriate boiler supplier.

    Golden Review Award: 2 From Our UsersThis was very easy to fit in place of my old thermostat and day to day functions are a breeze. The real question is do you really adjust your thermostat that often? After a few weeks I can see the novelty wearing off

    As an early adopter of the internet of things, thermostats have long been an option to connect and with good reason. The likes of Nest and Hive, which offer similar features to this Honeywell model, made a market based on energy efficiency and the ability to have things at just the right temperature. Would Honeywell, a long time heating manufacturer do the same?

    Installation first and with other similar devices it’s recommended you get a professional to do the complicated bit. There are essentially two components to this thermostat, a box that you connect to your boiler or heating system and then the remote unit which you can plug in anywhere in your house. This is a touchscreen which allows you to view some stats about the environment but also to adjust temperature and set schedules.

    This, like it’s competitors, is where it comes into its own. Once you’ve played around getting the device to connect to your WiFi, you can then use an app (or several) to control your heating. For anyone who’s had to try and set a schedule on their traditional thermostat this will be most welcome, as a pleasant UI replaces that complex system of button presses. Using it remotely is also possible when it connects and while the app isn’t quite as intuitive or stable as I’d perhaps like hopefully updates will get it there. Recent integration with the likes of Alexa and Apple Homekit are also a nice touch.

    Overall therefore, this is a solid competitor to others in the market. While it doesn’t have the style or learning capabilities of Nest what you get is solid – a decent screen connector, app and hopefully a more efficient home.

    Out of the box you get:

    – Install guide
    – User guide
    – Power adaptor
    – T6 Thermostat
    – Receiver box
    – Fittings

    The receiver box connects to your boiler which allows the thermostat to communicate with the boiler. You need to find a convenient place near your boiler to fit this little white receiver box. The black controller box has already been paired with your receiver box so no need to do this on install.

    Once fitted you access the installation menu by pressing the touchscreen menu button for 5 seconds and follow all the prompts on screen.

    This wired version is designed to replace a typical wall thermostat that you would usually find in a hallway that controls your heating. If you have one of these then the wiring should already be there. If not then you might want to look at the wireless version of this smart thermostat.

    I would recommend getting and electrician to fit this for you.

    The thermostat learns from your schedules and behavior and cleverly adjusts your heating to suit your lifestyle. For example it knows via your smartphone app that you are on the way home and can put on your heating.

    The main idea behind these smart thermostats is to save money on your energy bills and make heating your home as efficient as possible.
    This thermostat can also be controlled by the new Amazon Echo/Dots. Meaning if you have one of these you can control your heating with your voice. Very clever.

    The first thing is that this is not a plug in and go, I got a professional to install the receiver box as it has to be wired into your existing wired thermostat. Setting the thermostat with a 7 day program was easy enough. Next came “Geofencing” I must admit this was the first time Iv ever head this word. It means ” to use a smartphone’s location to manage comfort when home or away”. Also you can use a combination of geofencing and time scheduling to manage you home. You can download Honeywell Lyric App from the Apple app store or Google Play for all Android phones.

    The display thermostat I found fairly easy to set up my 7 day program. Setting my heating Monday to Friday as Im at work and to come on later at the weekend, you can also select a different temperature for each day. Also even set the timer to say that you are on holiday. When you open the app for the first time you need to create an account. You can also use more than one phone or tablet to control your heating. Being able to control your heating by phone does need access to 4G or internet. I live in rural Scotland so finding a 4G signal can be fun. Using the T6R Smart Thermostat over time will help me to save money as it manages my heating to the best economical way of heating my home.

    Golden Review Award: 2 From Our UsersA great quality piece of kit from highly regarded Honeywell. The only caveat is that you’ll need a ’24-230V On/Off’ or ‘OpenTherm’ boiler for this to interface with – in other words, generally only new installations. Check first. Other than that caveat, this can be highly recommended. Excellent software, the device syncs well with the App which can be downlaoded for iPhone or Google Android. You’ll need a wifi router in your house for the unit to connect to. Then, all can be activated and controlled remotely, even if you are abroad or on the way home form the airport. There are budget versions of this type of device available but this is very well designed and professional. Honeywell also have excellent after sales service.

    Golden Review Award: 52 From Our UsersThe Lyric T6R Smart Thermostat can be used to replace a standard electro-mechanical thermostat, or for new installations with OpenTherm-compatible boilers. In the former case, it can use simple on/off control to regulate the home temperature, and in the latter communicate with the boiler using the OpenTherm protocol to directly access data from the boiler. The T6R allows you to set and change the heating schedule (without relying on a timer on the boiler), and further to extend control to a smartphone app, more of which later.

    The package contains the T6R thermostat itself (an attractive touch screen unit), plus a ‘Receiver Box’ that mounts on the wall. These two devices communicate with each other using the WiFi in your house (and this seems to be the older 2.4GHz type only). The installation process is in two parts: Firstly replacing the existing wall thermostat with the receiver box; secondly installing the T6R and smartphone app.

    There is a detailed wiring guide for installing the Receiver Box, which shows a number of different options, depending on which type of boiler you have. If you have no experience with electrical systems, I would advise to call in a plumber or electrician to do this part; thermostats are usually mains-powered and can easily kill you if you fail to switch off the mains power to the boiler while installing.

    After carefully switching off the mains ring (and testing with a meter to ensure it was off), I followed the option for S-plan, which was the most similar to the way that my old thermostat was fitted. The box is 10x10cm, so somewhat bigger than the 8x8cm of the original thermostat, but installed without a hitch. The box has a LED to show you whether it is talking to the WiFi and another to show you when the heating is on. A single override switch allows you to fire-up the boiler now. With the box installed, it is now time to install the T6R.

    The touch-screen unit comes with its own 5V power brick (so it needs to be within about 90cm of a mains socket). With this powered on, next install the Honeywell Lyric App in your smartphone (from your favored app store). It asks you to create an account (on the Honeywell cloud) and leads you through configuring the T6R thermostat. The T6R and the Receiver unit are already paired in the factory so know how to communicate with each other.

    In my case the installation didn’t finish properly (the app would stop, or lose contact with the T6R), so I had to repeat the process about 4 times before finally everything was set-up. Hopefully, this is the one and only time I will ever have to perform this process though, since the unit seems to quite happily remember all the settings when not powered (which means you can safely move the thermostat between rooms if you choose).

    Now it is possible to create schedules in the app (and you can also edit/view them directly through the T6R touch screen), and you can view the current temperature and set-point in the app. You can invite other users to the system as well (using their email address), whereupon they can also install the Lyric app and also control the heating system.

    The app also allows geofencing, which means that your smartphone communicates when you go a certain distance away from your home. This allows the heating system to run when you’re around the house, but power-down when people have gone out for the day.

    The schedule settings can be quite sophisticated, with separate programmes for each day, or in groups of days (e.g. weekdays versus weekend). You can also create a special ‘holiday’ schedule to run minimal heating when you’re away.

    This is an attractive unit, offering the promise of reduced bills thanks to more detailed control over the heating than you normally get from the conventional timer and on/off thermostat. Also, being able to control the heating via an app (what’s now called the ‘connected home’) is an interesting new facility that I’m looking forward to experimenting with.

    First steps in the "Connected Home"

    Golden Review Award: 2 From Our UsersThe Honeywell is our first foray into smart home devices. I have deliberately stayed away until now to let the tech standards settle and the glitches so common to first to market products to work themselves out. The Lyric T6 is Honeywell’s latest smart thermostat and it is really good. It has a great app, plays nicely with Apple HomeKit and best of all does geo-fenced heating settings! The T6 comes in two different variants: wired to replace wired thermostats and wireless for systems already wireless or wanting to break free from wires.

    Inside the smart and well put together packaging are the thermostat, the control box and the a stack of paperwork in various languages. First off, this is relatively simple to install if you are DIY and heating literate, if not the included installation instructions are next to useless… The majority of UK properties are on y-plan heating systems i.e. you have a 3 port valve that diverts hot water from the boiler through your tank or through your heating or both, the water path looks like a y hence the name. This isn’t even in the installation instructions! The QR code on the instructions does give access to the honeywell wiring diagram library that would allow you to figure it out. That said, it isn’t too hard to figure it out but be really careful: ISOLATE THE POWER and BEWARE for LIVE WIRES that aren’t properly marked… Heating engineers seem to have trouble complying with wiring regulations. Time spend working it out will not be wasted!! Put simply, disconnect your thermostat from the main junction box (watching out for L/N feed that is not needed) and connect it to the Lyric control box. Then connect the control box back to where the thermostat was connected (red and yellow usually) and run a power spur (L/N/E). At the other end, simply connect the thermostat back plate to the red/yellow wires, check everything and power up! Don’t forget to set the heating programmer to ‘on’ for the heating otherwise it will override the thermostat…

    To set up the thermostat you need to download the lyric app and step through the system menu. There is a bit of back and forward to get the wireless to connect to your home network but the app is well designed and easy to use, leading you through the steps. You can set nearly all the functions from the app and then just tweak things like optimised start from the face plate. Once set up through Lyric, you can then add to Apple home kit very easily to combine with any other smart devices.

    What I like: the geo-fencing is brilliant, home kit allows Siri integration and it is incredibly simple to use. You need separate honeywell user accounts for each device in the geofence but it is simple to share access with both home kit and Lyric. Both my wife and I have it on there and it will lower the heating temperature when we are out and bring it back up when we get close to home. You will be able to work out the distance you need but for us it is about 10 mins travel time. Siri integration is a bit of a gimmick but fun nonetheless.

    Overall, not the highest specced smart thermostat out there, but isn’t the most expensive either. Installation is relatively straightforward but if in doubt get a professional to do it (30 min job, max).

    I gave this unit to my parents to install as I already use Google Nest – I will review based on there experience and then mine on a comparison with the Nest.
    They like this device. Although according to the person who installed it it was a little tricky (Cannot comment on whether that was their limitation or the heating system in the house) they love the fact that they can still easily manually control it in a physical and intuitive way, it has nice and bold numbers on it and they can still occasionally use their smartphone app to control it (They use the device to control it as much as the app to be honest) so it works well for them. This is why I am giving it four stars.
    However in my experience when compared to the Nest device there is no comparison this loses everytime. The form factor of the Nest is significantly better, the control unit can be moved anywhere you want it in the house, it works with Alexa and it controls the hot water. Admittedly I am a big fan of the Amazon Echo so Nest is much more integrated than the Honeywell device and if you do not use, or plan to use, the Echo then this may not be a concern for you but for me it would be a deal breaker. So in short my personal conclusion is that this works well and is better by a mile than a non app controlled thermostat but falls short in many ways compared to the competition. Just my opinion and it may work well for you but before you buy compare with the many other devices available.

    Golden Review Award: 23 From Our UsersTwo version of this product exist, this one which features a hard wired wall mounted thermostat and the boiler control module.

    The thermostat needs two wires between it and the boiler control unit which needs mains power and to be connected to your boiler to turn it off and on.

    The other version Honeywell Y6R910RW8021 Connected Wireless Programmable Thermostat – Black is similar in operation but the thermostat has a built in stand which also has to be plugged into the mains.

    This version seems to be designed to replace a conventional wall thermostat, typically mounted in your hallway wired back to a central heating programmer or your boiler.

    I should point out the instructions say the following in large print…
    “Must be installed by a competent person! Read these instructions carefully. Failure to follow these instructions can damage the product or cause a hazardous condition.”

    The installation instructions are pretty clear but seem to miss how to remove the thermostat from the wall mounting plate. The white part just pulls straight back, see my photos.

    I have fitted this to replace a SALUS IT500 Internet Controlled Thermostat

    My current wall thermostat was wireless but I knew the original cables were still hidden behind it so I used two cores of the triple core and earth to feed the new thermostat.

    After turning off all power I removed the existing base unit moving the four wires (mains and boiler control) to the quite large Honeywell controller which has mounting holes in standard locations.

    The wires to the thermostat were in the flush wall box behind the controller and fortunately they were just long enough to reach the connection strip.

    I should also point out the system supports boilers with OpenTherm.

    “OpenTherm is a multi point to point communication protocol for use in residential heating.” in which case you use two different connections to the boiler allowing the unit to obtain the status of your boiler including faults. My boiler predates OpenTherm.

    Once the cover was back on the controller it was time to turn on the power.

    Display illuminated asking to run setup which included setting the time and date which I thought a bit odd for an internet connected device (checking makers website later, the system can be installed with no external connections thus I guess the clock needs setting).

    I then loaded the Android App and at this point I think my first mistake was made as on the login screen it said thermostat detected and offered to set it up which I had to do again later after creating an account in the app.

    So create your account first and login (name and email address is all it asks for and extra users can be added to control your system).

    Setup is pretty simple except you need to know your home WiFi 2G password (5G not supported) and you also have to select the Thermostat’s WiFi from your phones network setting so the configuration data can be sent to it (It only is a a WiFi hotspot while in setup mode).

    It offers 12 or 24 hour display and once the app reloaded it also displayed the heating times in 12 or 24hr format.

    Temperature is set and displayed in 0.5c units and I like the fact it always displays the time and current temperature on its touch screen and no batteries to be replaced.

    I subjected the system to a power cut and it seems to set the date and time okay plus the Android app seems to work well (Control from a web browser is not possible, only from the thermostat or the Android or Apple app).

    The thermostat can display plain English messages should there be a problem and I assume knows about summer and wintertime (no mention in the instructions).

    And so far it has worked with no issues – fingers crossed 🙂

    A Modern Replacement For A Conventional Hard Wired Wall Thermostat Offering Remote Control Of Your Combination Boile

    Golden Review Award: 2 From Our UsersAs I have been using a Netatmo system for about a year, I thought I would compare the two systems.

    Firstly, fitting. This took me about 30 minutes, hooking into my combined heating and hot water controller.(*)

    I liked the fact that this is a mains operated thermostat. I am not too confident about battery operated ones like the Netatmo. The Lyric also has a far superior display, as it can use LEDs. The ePaper display of the Netatmo is OK, but all you see is the set temperature, the current temperature being almost invisible. Plus, apart from boosting or lowering the target, Netatmo offers no control whatsoever without having to dig out a phone, computer or tablet and firing up the appropriate app. The Lyric Thermostat has a full touchscreen control, far more user friendly. In standby, it elegantly displays the current temperature and a small time.

    One thing I disliked in the Lyric is that in programming it, you have either 5+2 or 7 individual days, not the same program every day. My needs are simple, though, and two periods, low at night and warm in the day, suited me fine.

    The Lyric uses WiFi to communicate with the Honeywell servers.Communication between thermostat and base unit is also wireless. I will report back on any problems there, but the Netatmo uses the same mechanism.

    One consideration to bear in mind is the complexity and user friendliness of current technology. Although you can achieve more with the Netatmo, it is at the expense of excluding other members of the family from using it if they are not confident enough, and let’s face it, who wants to use a mobile to adjust their heating, as the ONLY method available? Theoretical efficiency meets practicality head on.

    There is no IFTTT control, surprisingly. I have used this to cut out heating if the conservatory gets hot or to boost it if it is freezing outside, but again, such features would only perplex my wife and result in her having to install a new simpler system if I died. Also, IFTTT is currently undergoing a transformation which is making it unreliable. I have had it turn off my heating and not turn it on again more than once.

    The geofencing on the Lyric is complex, far more so than is possible using IFTTT at present. IFTTT has geofencing, but if you set it up on two phones then you will find there are conflicts. One person leaves and the other is left to shiver. The Lyric has a system which links a number of phones to the system, turns off heating when the LAST person leaves, and turns it on when one person returns. There are all sorts of restrictions, though, as each person must have the app running in the background at least, have location services enabled, not have a flat battery or in some cases not be speaking on the phone, etc, so I am leaving this disabled. There are too many things to go wrong. As for the Nest solution, well, having to walk past the thermostat occasionally to let it know you are still in is just plain silly!

    It is early days yet, I only just fitted this system, but I am impressed at its general usability. Just being able to read the temperature without having to walk up to the Netatmo thermostat is well worth it. I will report back on any issues I have.
