Would recommend 5 Stars
Very easy to install myself
Easy to set up a Wi-Fi
Using the app and setting the timer schedule and everything else is really easy
After a couple of weeks from installing first time, the thermostat works out the best settings for your house.
I am in the process now in buying the smart thermostat valves for all my radiators. So my whole heating system with controlled by One thermostat on one app as well as being able to control it via smart speaker(Alexa)

Excelle
Reasonably easy to install, and very easy to use.
Works flawlessly with Alexa and Siri, and the app and online pages are very easy to use and understand.
Added some Netatmo radiator valves too, so now have complete control over the house.

Does exactly what it says on the tin!
This Smart Thermostat has slotted in nicely to my smart home eco-system. The installation in my case was extremely straightforward (your mileage may vary) as I was replacing an old wired thermostat. The only gripe I have is that options to mount it to the wall were limited and just didn’t work in my case since the assume the wires for the existing thermostat are embedded in the wall. In my case, they ran through a surface mounted duct but it was nothing that I couldn’t work around. Must also mention that I got a very quick response from their Technical Support team when I emailed them to check the wiring diagram from my old thermostat.

Bottom line – I’m a very happy customer.

Perfect balance of smart and configuerable
Great product. It has reduced the amount of time my boiler is on but the house is always the right temp.

impressed!
1 – didnt need any wires to the router
2 – didnt need any wires for the actual ‘front-end’ device
3 – connecting the app was really straightforward – fool-proof
4 – the app itself is really smart – has even history of temperatures
5 – security seems quite decent – notifications when logons are made from new devices etc.
6 – extendable – wont use it, but potentially could come handy one day – can be connected to smart thermostats as well.

nothing to complain even if i really try hard. price was more or less decent, the install was easy – got it done by amazon as well.

Fantastic as a Smart Thermostat, shame the rad valves are so expensive.
Great functionality and simple to use app, works with Alexa.

Does everything I want and does it well.
My old mechanical thermostat was well past it’s best and I had been looking at smart thermostats for a while. I didn’t want to pay for a lot of functionality I would never use, such as geofencing, turning on air conditioning etc… so this seemed the best choice.

My old thermostat had 4 wires and Netatmo answered my enquiry within a day sayingvwhich wire to use. Installation took about 25mins and unlike most technology I buy, worked first try. The display auto rotates and I decided I preferred the display horizontal.

The app is very intuitive to use and I soon had my schedule and temperatures set up. No more trying to push & pull the little pins on my old timer for me ! The first few days were very hit & miss with a few chilly mornings and one very sweaty one. But once the adaptive programme started to do it’s thing the results have been amazing. The temperature is exactly where I want it, when I want it and is stable to within 0.5c ( something my old thermostat could never get close to )

It’s early days yet to see if it saves as much money as claimed ( I am sceptical on that ) But The ease of use, flexibility and excellent control of the temperature are worth the money. I’m a bit addicted to checking the inside temperature while I’m out, but that novelty will soon wear off. Alexa use is a bit limited and again a novelty that wore off quickly. Now my schedule and temperatures have been refined, it’s pretty much fit & forget.

Super control and informatio
Fitted this device to replace a Danfoss control system. This is on an oil fired Rayburn central heating/cooker and it works extremely well.
I have experienced the Hive system, which is also excellent, but Netatmo provides graphs of actual versus target temperature and also learns the speed of warming the room, so that it can kick on the heating at the right time to achieve the desired temperature.
Really impressed – now I can control heating whilst away from home and prepare the house before I get home!

Netatmo Thermostat replace old mechanical thermosta
I installed the Netatmo thermostat to replace a Honeywell mechanical thermostat with four wires. The Netatmo manual is confusing in its description of how to wire up in this situation. You need to identify the two wires that control the boiler and system heating. So if there are four wires like mine the earth and neutral wires are not used and should be bent back and insulated with plastic tape. Make sure power is turned off before opening up and working on the wiring. The two remaining wires should be the live feed from the boiler and a switched live back to the boiler. In the old fashioned mechanical thermostat a physical switch is activated when the thermostat calls for heat this activates the boiler heating circuit. The live in wire should be connected to the top Netatmo connector and the switched live wire to the bottom Netatmo connector.

A key reason for installing the Netatmo is to improve control of the home heating system and hopefully save some cash in going so. The old mechanical thermostat and set schedule of on off heating times is fine but it does not predict the most efficient times to turn the heating off and on it reacts but does not learn. The Netatmo learns the insulation properties of your home, uses outside temperature to predict an efficient on off time. So you should make sure that the heating prediction is enabled in the app – it takes a few weeks to learn, meanwhile if the thermostat is installed outside of a winter period home temperatures may be acceptable for most of the day and night but need occasional boiler bursts to top up in colder periods. To do this I set the default time of manual set points to 30 minutes rather than the default 3 hours. Then if it gets a tad chilly I use the app to increase the required temperature for a boost in heat. I then have the scheduled temperature set below that required heat so that the Netatmo does not call for inessential heating. The heating graphs are very useful – the black curve shows the internal home temperature, the orange line the preset temperature and the orange vertical bars indicate the boiler burn periods. In winter I increase the preset temperature, in this case the black curve will be below the orange line when there is a need for heating.
My relay is plugged in a wall socket close to an Apple Express WiFi and connects at 72Mbs, the relay is about 20 feet from the Netatmo and has a robust WiFi connection that is rock solid. The setup on an iPad or iPhone was very easy, WiFi passwords and stettings are automatically read by the app – at one stage a code is displayed by the Netatmo this is scanned by the iPhone to make a secure connection – it is a twelve digit code, hack proof I would say. Once connected heating can be controlled via Apple Home and Siri voice controls remotely.

Update: My boiler developed a fault and Netatmo sent me an email as the heating temperature had not increased – thanks Netatmo I was able to reset my boiler and the wifey didn’t have a cold shower.

Smart home
Fantastic bit of kit, took at bit of time to install it with our very old boiler but got there in the end. The app on the phone and the website is fantastic and you are able to do so much and view how much money you have saved.

Nice
Its a great stat, the instructions are a little poor, but their online support is great.

It took a couple of time to connect the stat to my phone, then my internet, then the app will walk you through different times you are in and the temps you would like, and i believe it learns from there.

I like the the way you can connect it to alexia and set it by voice, even if some of the features arnt there for alexia, but in that case you can use your phone.I have recently got the amazon echo, and loving all the devices that i can connect to it, and this one works very well.

Good Product.
This replaced a Tado that had died. Netatmo is much simpler to use and set up. Not as simple to install as the blurb suggests but not beyond the more competent.

No Problems!
The Netamo smart thermostat replaced an existing wireless thermostat controlling a gas combi-boiler. Installation required some electrical rewiring (not the fault of Netamo) otherwise there were no problems. Communication between the relay, thermostat and our home WiFi was established without any significant issues. As stated the device works with Amazon Alexa/Echo without issue although the iOS app is the primary control interface. Although we have retained the old control system as a backup the Netamo coped with the recent cold-snap without any problems.

Easy to set up replacing the built in timer and ...
Easy to set up replacing the built in timer and wired room stat I previously had.
Great design!
Not checked my gas use but I’m sure I’m using less. If I’m late at work or out for the evening I turn off/down from my phone!

I thought I would be able to connect the two thermostat to 1 relay but it looks like you need to plug in the two relays
I got two of these as I have two zones in my house. I thought I would be able to connect the two thermostat to 1 relay but it looks like you need to plug in the two relays.

Once you have them on the walls the setup is quite straight forward using the netatmo app.

The only issue is that it is supposed to be compatible with HomeKit but the 8 digit code is nowhere to be seen and no way of retrieving it. I will be contacting Netatmo about that.

Other than that, I think you save on heating costs simply because you can turn the heating off remotely for example if you are not at home and then turn it on 20 minutes before you arrive.

Edit: customer service is really bad, it took ages for them to reply and when they did they copy/pasted the answer. Still looking for my HomeKit 8 digit code

Works well
Easy enough to install. It does its own thing and the house is always nice and warm.
If you do not have a room thermostat at the moment you will need to be OK with accessing the boilers control panel and connecting the Netatmo control unit to it, but it is easy enough to do.
Accessing it from the phone app is easy and the app is well laid out.

Excellent Thermostat - HomeKit Compatable
I purchased this to replace my existing non-smart wireless thermostat.

My purchasing decision was between this and the Tado system but went for this one on price as the Tado cost over 300 including installation. Whilst Netatmo do have some approved installers on their website my local plumber charged me 50 quid and said it was relatively painless to do.

In terms of installation you essentiallly have two boxes, the relay, which is wired to the boiler, and the thermostat itself, which is battery operated. The relay also connects to the WiFi in the home unlike Tado and Hive, which require an additional hub connected to the router. This may not be an issue for all but I already have a Phillips Hue Hub so ideally didn’t want yet another hub.

Once wired up (but before connecting to router etc) this basically operates like a non-smart wireless thermostat, so even if you internet goes down you won’t lose control of your heating.

The setup process is easy and can be done from your phone. Once this is done, then you can get into programming heating schedules etc. HomeKit setup was also a doddle, the only downside is that HomeKit works in incriments of 1 degree Celsius as opposed to 0.5 on the Netatmo app. This is also compatible with Google Home and has been linked up with my Google Home speaker (also works with Alexa but can’t comment on setup process).

The thermostat itself is highly programmable and you can also set it up so it learns (similar to Nest but not quite the same) how long it takes to heat your home. One area where it is distinctly behind competition (Tado) is that it doesn’t implement geofencing but all things considered, this was 99 plus installation whereeas Tado Thermostat plus wireless extension kit was 278 plus installation.

The system facilitated future expansion as you can also add smart radiator valves and further thermostats.

Overall I think this thermostat offers excellent value for money and would definitely recommend for someone who is looking for a capable smart thermostat but doesn’t want to be tied into the Hive/Nest ecosystem.

Great Thermosta
This thermostat is simple to install, The associated app is easy to use and there is also a touch pad unit for the house.
Myself and 3 of my friends have it installed in our homesand are all very impressed.

It takes about a week to settle down, but after that it's worth i
The only downside of this is the screen – I’ll get that out of the way first. It’s not that limiting though as I usually use my phone to control it anyway.

Once set up, after approx. 7 days it offered me a new setting (to more accurately control the heating) – what a difference. Before that setting, it acted as a pretty basic thermostat (and I wondered if it was worth the money just to be able to switch my heating on and off remotely – the swings were high – up to 3C – as it made no adjustment for the fact my radiators retained heat after heating or that it took a certain time to get the room up to temperature). Now, the swings are low (less than 0.1C) and the boiler is on for shorter periods (more often, but overall less time). This is what I paid for. Smiley face!

Setting up is pretty easy – I wired it in a way not shown in the book (hard wired the relay into the timer – basically the relay connects the black and grey wires when the thermostat is on, so I connected the grey to live and the black to switch the boiler – if you don’t know how these things work I wouldn’t try this though).

Netatmo thermostat.
Arrived as expected. Job done. From opening the box to controlling the heating from Alexa all achieved in less than an hour. Will update after I’ve reviewed some graphs etc available from the Netatmo app.

Dece
Looks nice and the default 3hr period for manual setting of temperature is convenient. Unfortunately, as other reviewers discuss, its thermostat is slightly off.

I’m seeing a +/-1 degree variance which means it often doesn’t come on as early as it should.

Additionally, Alexa support is pretty basic, with no way to ask what the temperature is currently set to.

Update: An Alexa command to ask what the temperature has been currently set to has been added.

A Smarter Way to Control Your Heating
I’ve purchased two smart thermostats to control my heating in two places. Neat design but connection with Alexa or Home was frustratingly difficult. Technical Support was patient and helpful with the first installation when I couldn’t get the central heating boiler to link with the room thermostat. However, once set up, it’s a great way to control, monitor and change the temperature remotely. I particularly like the ability to boost it before returning home. Netatmo emails a link to access the month’s energy saving graphs which will prove interesting during the upcoming Winter months. I have no doubt the savings will pay for the thermostat and, with additional valves planned to regulate individual areas of the house, even more savings should be made.
