Google Nest Protect – Smoke Alarm And Carbon Monoxide Detector – The Smoke Alarm That That Others Look Up To (Battery) 3 Pack


Nest Protect

The smoke alarm that others look up to.

Nest Protect is a smoke and carbon monoxide alarm with a split-spectrum smoke sensor to detect both fast- and slow-burning fires. It can send an alert to your phone,[1] speak to you and even light the way in the dark.

Nest Protect

It tells you what the danger is and where it is.

The Split-Spectrum Sensor looks for both fast- and slow-burning fires. It also has a 10-year CO sensor so that it can tell you where poisonous, invisible CO is hiding. And all your Nest Protects speak up at the same time to tell you what’s wrong and where the problem is.

Nest Protect
  1. Nest Protect

    Easy to install.

    Nest Protect only takes minutes to set up with your iOS or Android device. Once you’ve added each of your Nest Protects to your Nest account, they will automatically connect to each other.

  2. Nest Protect

    Thoughtful, not annoying.

    Nest Protect checks itself over 400 times a day and lets you know if something is wrong. It also has Steam Check, so a nice, relaxing shower shouldn’t cause your alarm to shout at you.

  3. Nest Protect

    You’ll know, from anywhere.1

    Nest Protect can alert your phone when something is wrong at home. You’ll receive a message if the alarm goes off, if the batteries start to run low or if a sensor isn’t working.

Nest Protect

1 Mobile alerts require working Internet and Wi-Fi.

    Bought to replace my out of date Gen 1 model which had been in operation for the past 7 years (original models had a 7 year life) with absolutely no issues. On receipt I checked manufacturing dates (on back of unit – it should be on the box!) and I’m pleased to report it was made in Jun 2021 so I should have 10 years(ish) use from this one. All good so far – now the p@@@ taking by Google! They have changed the back fitting plate – WHY!!!! It meant I had to remove the old plate, fill in the old holes, drill new ones, touch up paint the mounting area, wait for the paint to dry and fit the new back plate. But wait there’s more! They have also changed the connector/plug to the unit – again WHY!! I had to cut the old one off and fit the new one. What should have been a literal 5 minute job (setup aside) turned in to an hour of effing and jeffing! I’m from an engineering background and can no reason to change those two things other than to alienate customers.

    Rant over – the Nest Protect is a great piece of kit, well made, easy to set up, highly functional and integrates well with my existing NEST products and other smart devices. However, I’m considering upgrading my NEST thermostat and if they’ve changed the mounting/wiring etc, they can take a flying you know what. I was angry when they ditched the ChromeCast Audio device so they could make more money selling their crappy mini’s so that will be the last straw – sorry still ranting…..

    I “invested” in the first generation of Nest protect products which are now starting to reach their end of life dates. This is annoying because I am now faced with a bill for 000’s to replace them all but when it comes to safety, you just have to see the bigger picture and suck up the cost, taken over the lifetime of the product it is not so bad. Annoying then that the second generation products that I have bought so far were already 6 months into their 10 year life span but I think that is probably fairly normal.

    If you are replacing a Gen 1, you will need to change both the wiring (different plug for the mains version) and the mounting plate, quite why Nest could not have kept the plug the same I do not know, possibly because the old one is a pain to release but it is not something that you should be doing very often. As always though, all of the fixings that you need to complete the job are included.

    Once you have done all of this though, set-up via the app is very straightforward and I had the replacement up and running in a few minutes. If you are replacing/upgrading, probably best to delete the old product from the app first to avoid any naming issues.

    I still think that these are the best on the market and I have always found that the customer service from Google Nest to be excellent.

    Got these, but found that 2.5 of the 10 years life had already expired before bought them so they expire in sept 2029 rather than sometime 2030/2031.

    Was easy to set up although surprisingly nest app didn’t have a replace option you have to delete old and add as new.

    It took time to get it to link to our WiFi, and we had to add it to the app twice because it ‘lost’ it, so it wasn’t easy to install, but now it’s in, it’s very good. We wanted a smoke alarm that wouldn’t go off every time we made toast or ran a bath and the smart features on this alarm have achieved that. The alarm hasn’t sounded yet because when it gives us a warning, we are able to stop it.

    Best thing is the warning feature, so you can stop it going off!

    Wired alarm lasts up to 10 years. Product itself is great with a multipurpose smoke alarm and CO alarm.

    When testing its features, the Nest app tells you details of when the alarm is active, when it’s been silenced and when the levels of smoke etc decreases and if issues persists will phone an emergency number that you choose.

    Only issue is that the alarms cannot be displayed on the hub unless you previously had a Nest account as you’re unable to log into nest through the Google Home app.

    Great product from Nest. If you have a preexisting wired installtion note the NC link is missing from the terminal block. The WiFi setup is a bit annoying, since the MAC address wasn’t on the box or on the label on the device. Still no support on the Google home app which is hard to believe! No other sensors in device such as temp humidity to feedback into the thermostat, or any air quality metrics which was very disappointing. Expensive for what it is; a wifi enabled smoke detector but if you have bought into the Google ecosystem then this product is great addition although missing a few critical features that would have truly made it smart.

    Installed these to replace standard smoke only type alarm. Installation straightforward using kit supplied. Setup using Nest app seamless.
    So far has surpassed my expectations. Did a ‘live’ test using a match and the response was superb. Great that you get the alert on your phone also, fires can and do start when you are not home; can always get a neighbour to check if you receive an alert.
    Really like the ‘light my path’ function. Have been able to do away with my plugin socket night lights.
    Well worth the extra money in my view versus a more basic detector.

    Clear instructions for set up and installation. I’m no electrician, but the step by step guide had me installing three of these around the house.

    Great functionality and looks smart too.

    Cool feature of a white light that comes on when you walk by the alarm in darkness.

    This was to replace a gen 1 Protect which has worked perfectly for 7 years and needed replacing due to sensor life the gen 2 have a 10 year sensor life. Easy to exchange and remove the old from the app and add the new one. I have 4 Nest Protect sensors and they all interact, all battery models highly recommended.

    I ordered a battery powered version from Amazon. It arrived in correct box but was a wired version in the box with no wires. Had to return for a refund. 1 star for that. I already have 2 of these in my flat, 1 wired and one battery powered. They are both interconnected which is great. The nest app is great for status updates, testing and cancelling false alarms. If there is a problem in your home you’ll get an alert to your phone. They stay interconnected even if your WiFi is down, you just won’t get alerts to your phone. Recommended.

    This is a premium product from the moment you open the box. Even the supplied self tapping plasterboard screws are the best you will have ever seen. Very easy to install if you already have mains smoke alarms, and they look great once installed.

    My batteries died in my old alarm. I already have a lot of nest and Google products so it was a no brainer for me. Functionality is good and I like that it silently tests it self. The night light is genuinely awesome, you can change the brightness and it’s really good for going to the loo in the night.

    I have an office at the end of the garden wanted to get a fire alarm that would sound in the rest of the house or notify me, if there was a fire. Nest does this nicely.

    The others I have in the house are great, do like the night light that comes on if you move about.

    Quite sensitive to lots of dust from building work. Sanding dust can trigger the alarm, you do get a warning saying there is smoke in the house.

  20. AlexisCase says:

    Very easy to setup and install. Everything you need is included – all you need to do is download the app, create an account and link the smoke detectors to the account you have just created. They talk to each other if smoke is detected. The pathway lightening brightness can be changed on the app for each unit. It’s a big shame it’s not Alexa compatible. The sound/voice on the units are nice/clear and loud.

    The units are possibly old stock as you don’t get the full 10 years lifetime on the product. Mine was short by 14+ months

    Nice and easy to install. The Amazon ones are also around 3 months old (10 year shelf life from manufacturing).

    Other shops stock 12+ month alarms, so nice to eat relatively new ones and not old stock

    Golden Review Award: 3 From Our UsersWhen I say fabulous, one of our main concerns when leaving the house unattended is that the cats could be trapped inside when there is a fire. With these alarms (we have three fitted inside the house and a fourth in the garage), we have a linked system that is hard wired in and with a battery back up that will alert us if smoke is detected in the house. The system undertakes regular sound checks to ensure the alarms still work and it is reassuring to see a full history of each alarm in the Nest app. Should there ever be a fire when I am not in the house, I can contact a key-holding neighbour that can rescue my cats or at least call the fire brigade. Of course, these also alert to the threat posed by Carbon Monoxide and with an alarm as loud as these, you are unlikely to sleep through the alert (as long as you have enough in your home; don’t stint on safety).

    I bought three Generation 1 Nest Protect (Wired) Smoke Alarms around 5 years ago to replace the basic-but-linked ones we had. They worked really well… until last weekend when one of them announced (in the middle of the night! Like, why!?) that its CO sensor had failed and that I should replace it immediately (and then continued to beep every so often afterwards). Literally, the following evening, another announced that it had ‘expired’ and that it too should be replaced. So… as we’d been fairly pleased with their general burnt toast / bacon fat / wafting BBQ fume reporting… and that they also functionally tie in with the Nest Thermostat that we also have (and by the way, we’re on our fourth as apparently – warranty replaced units aside – they don’t seem to last much beyond five years either), I ordered three wired 2nd Generation versions to replace them.

    Couple of things to observe when you’re replacing / upgrading the G1 version:- Despite the very similar appearance of the G1 and G2 Nest Protect devices, the baseplates are completely different… so the devices aren’t interchangeable with them. And none of the existing holes line up… so be prepared to get the drill out as you’ll be re-fixing everything. And the mains connector is also not compatible, however they do supply neat terminal blocks to make changing the cable connector over fairly easy (please remember to isolate the circuit your smoke alarms are on when installing!).

    Once you’re past that and they’re up and running, they pretty much look and function in exactly the same way as the the previous versions… with the only exception (that I’ve noticed) that you can silence a triggered alert from your mobile device… oh, and that the CO sensor should last ten years this time… instead of the five’ish I got from the last one.

    We have 3 smoke alarms in our home (hard wired). One started bleeping the other week, I took it down thinking it was the battery, then saw the replacement date on the underside. 2016. I never even knew there was a 10 year life span on smoke alarms! We bought this house as a new build, and were never told this. Anyway, do we buy the same again (18 each on Amazon) or go for the nest type. We went for the nest for a few reasons. They have a CO2 alarm too, (our house didn’t have one), they have a nightlight, they constantly check themselves.
    If you added these together, smoke alarm 20, CO2 alarm 20, nightlight 20, the nest isn’t too far off the mark price wise. I still reckon they are 15-20 too dear, but we decided to go for 3x nest units.
    They were easy to install, as the wiring was already there, it was just a case of putting the nest connectors on, then on the ceiling they go. The app is straightforward.
    The best thing about them…The nightlight. Very handy. Can spot you on the landing/hallway very easily. When it comes on and goes off it does it gradually so doesn’t wake up the rest of the house. Can be changed in the settings, ON,OFF, etc, brightness.
    The wired units also have a tiny green LED on them which shows there is power going to them. When you turn the lights off at night to go to bed, the unit glows green for a couple of seconds to tell you its OK.
    It’s a shame they are so dear especially when you need 3, but breaking the price down over 10 years its not all that bad.
    Ours came with manufacture dates of september 2020, and 1 had December 2019. I really don’t think it will make any difference as they have been boxed and sealed all this time. I just labelled them all up as fitted in Feb 2021, replace 2031.
    TBH, our old ones were 5 years out of date, and I noticed they were manufactured in 2006, and our house wasn’t built then! So, builders don’t care. I guess they were in a container with all the other house fittings. If it hadn’t been for the old unit bleeping I would have never looked, When we bought the house I looked at them and thought ‘brilliant, hard wired smoke detectors, i’ll never have to look at them again’.

    Bought to replace 3 that had reached their expiry date (sorry but they don’t last forever). Good life on batteries but seems only if you use Energizer Ultimate Lithium (as supplied). Easy to replace each alarm in turn by deleting the old one from the app and then adding the new one using same ‘name'(eg kitchen). ‘Path light’ function is great for night time “visits” as saves switching main lights on waking the whole household.
    Will buy again in 10 years time or an improved model if available.

    Really like these smart detectors. A note to be aware of. They are factory set to have a 10 year service life. On the rear of the unit it has manufacture date and replace by date. So if its old stock the service life will be shorter. When they reach the end date the unit constantly chirps and then take out the batteries and despose of said items. I have had a few from other sellers that had 2016 and 2017 manufacture date clearly old stock and were returned.

    These were replacements for previous Nest devices that were dying. So note that it seems that the 9 year or so lives are related to manufacturing, not activation dates. So these two – ordered and installed together – have death dates 6 months apart (in 2029). Amazon should sell these with death dates given at time of order. To find the death date look at the technical info for each devices in the app. Otherwise fine – though the incompatibility of mounting plates and screw holes is tedious!

    Bought 3 units to replace 3 original wired non-smart smoke detectors (cheaper to buy 3 singles instead of the 3-pack!). Units received were all the same except manufacture date meaning 1 has a 10 year life cycle left, other 2 around 9 years (disadvantage to buying from Amazon unfortunately). I’m by no means familiar with wiring / installation and it took a while to get these wired by recycling previous wiring for original units (not a Protect issue but I blame builder / original electrician for being over keen on those plastic wiring blocks and small holes in roof space!). Once setup at my desk eventually installed in the ceiling there were no real issues. One unit dropped off the wifi and took quite a few efforts to reconnect, requiring me to resort to resetting it and approx and hour rejoining). The design of the round plate connecting to the ceiling and the circle alarm is very fiddly when trying to attach ceiling too.

    I like this product because it is integrated with the Google family and allow interconnection with app and other devices. The very negative is that is very expensive for a very basic work, where you rarely interact (fortunately) with it. In its main functions, it works properly. Its interconnectivity and smart features are great but only used during installation and testing. I like the feature of the light that turns on when you walk at night close to it.

    First foray into the smart home world of smoke detectors.
    Wiring instructions and connectors supplied make this a relatively easy ish (if very fiddly) installation. Hardest part for me seemed to be getting the alarm to sit on the backing plate.
    Worth checking the area where previous smoke alarm was for fit especially any wiring box and areas not painted that won’t be covered when you fit the nest alarm – avoids taking it down again.

    You need apparently a google home account which then directs you to a nest app download, the two appearing not to link to each other – but the nest app works okay.

    Fun for a few hours of annoying the family with the test function.
    Night light does work okay if you boost your highest value – only works when no other light source impacting the sensors the alarm must use for this ( based on my testing) anyway.
    Alarm happily tests itself regularly and you can see that on the app so great comfort.

    Another on order to add to the alarm family.

    Worst point, advertised 10 year life of product, already a year old when it arrived from Amazon – sept 2020.

    I bought two Nest Protect to replace my precious wired smoke alarm. Setting both up using the nest app was simple and easy to do. As yet, not integrated with the Google Home app but that seems to be in the works. The night light is a nice touch and helpful. The brightness can be set via the app. This feature can be turned off if required.

    Now for the physical fitting. I’m no expert, but class myself as a confident DIYer. The wiring diagram is easy to follow and all the connections are supplied. The down side is the connection to the alarm itself. It sits proud approx 5mm above the back of the alarm and offset to one side. This means you need to make sure the hole in the wall/ceiling is wide enough and deep enough to accommodate the 3 connect blocks and the connection. My previous alarm sat flush with the ceiling so I had to go to task on the ceiling, easier said than done when my home was built in 1890!

    Overall great product!

    This is the 4th Nest Alarm we have added to our house and I remain as happy with this one as the pervious 3, if not more so. Easy to set up and easy to install.

    Took my time choosing a new fire alarm after redecorating and 3 months on im very please with this one. Love the motion sensor night light, subtle but very effective. They look so much nicer than the cheaper fire alarms. Wiring up was a little tricky, I would advise you use your own chocolate block screw connectors not the push in ones supplied. With i tried them they kept unclipping and it would lose power/connection. Would recommend

    Set up is relatively easy & once hard wired into the power supply, you are good to go.
    Night light is a little bonus, that I didn’t think we would notice, but it really is a nice touch.
    I really like the app and the monthly health checks.

    No hesitation in recommending these units, being old school I would recommend installing ones that are hard wired to an electrical supply.

    Love these smoke alarms – the most important point is that it uses voice as well as an alarm – the voice wakes the kids up straight away whereas we know they will sleep through a regular alarm (we set the alarms off in centre parks once and it was SOOO LOUD but the kids all slept through it!!).

    Also love the path light function on the landings – great feature to give a bit of light at nighttime when you are moving around the house.

    Look quite smart on the ceiling.

    It’s a lot of money for a smoke alarm but it’s a lot more than a smoke alarm and totally worth it from my perspective.

    These are by no means a cheap smoke detector but they are really good.

    Once you connect it to power and connect to the internet it opens up a lot of possibilities

    We have the detector linked to IFTT so when smoke is detected it turns on all the Philips hue lights we have and makes them red (this is the best colored light in the event of smoke)

    Yes. It’s expensive but even the voice prompts are really helpful.

    We have the detector linked to IFTT so when smoke is detected it turns on all the Philips hue lights we have and makes them red (this is the best colored light in the event of smoke)

    Yes. It’s expensive but even the voice prompts are really helpful.

    If you haven’t installed the wired version before, the installation is not as easy (understandably) as the battery version. The main issue I found was that the plug on the back of the Nest Protect obviously sticks out and must go into the hole in the celling but the plug IS NOT centred on the back. This means that you need to line up the mounting plate off centre to the hole in the celling. If you factor this in, then it is much easier to install.
    Also, be aware that although the Amazon description claims that it has a 10 year lifespan, ours did not. It arrived with just over 9 years left. I queried this with Amazon and they kindly sent out replacements, however, these were further “out of day” than the original ones sent. Other than this the product is every bit as good as other reviews say. We now have several in our house and they work brilliantly. Expensive, but brilliant none the less!

    Disappointing that mine was made a year ago so I lose a year on the ten year life of the product. Also be aware that wiring / connection blocks that come with it may require you to hack a bigger hole in the ceiling then originally there to house them. Time will tell if I still like the product itself. connected seamlessly to my Goggle home and will update as i go.

    Fitment and set up are fairly straightforward. The wiring kit and connector blocks work nicely. Worth making sure that the ceiling hole for the wiring is bored out to the same diameter as the hole in the centre of the backplate or it will cause issues with fitting the unit to the plate once you’ve plugged it in; Its also easier if you feed all the wiring into the ceiling hole before trying to fit the detector.

    This has been installed in my kitchen for about six months now and I have to say that I’m really impressed by it. The system runs monthly checks on both alarms and notifies you through the nest app, I especially like the voice notifications when smoke is detected In house (cooking) plus the built in light is great when you get up at night for a stroll around the kitchen ,it bright enough for you to see so no switching on lights, I plan on replacing two other smoke alarms with this great product.

    Wow, I have to say I ma very impressed! Works like magic, very modern design and it will glow when it’s dark and you passing by it. I am very happy with the purchase. You can control it from your mobile, it will show you timeline of all the events, just fantastic. Hope it will work like that all the time. A little bit expensive but I still think it’s worth the price. When you buy mains wired they are cheaper, but definitely buy multipack as this is best value for money.

    Very easy to install and set up ( link to your WiFi). I Brought 3 of the alarms after buying an old house and wanting to change the the smoke and CO2 alarms. Really like the fact they all link to each other, for example we had an alarm activated on Boxing Day, the roast started smoking from fat (roast pork) and whilst we were in the lounge the alarm spoke and said there is smoke in the hall way, whichever alarm is activated first it then relays the message to all the alarms in the house upstairs etc and sets them off, so it’s not just one alarm that sounds. I Like the fact the lights also tell you what is going on.the pathway light is great. The alarms self test monthly and you can see all the statuses via the app. CO2 part has a great feature that if you link the alarms to a smart thermostat it can shut off the boiler if CO2 is detected even if your away from the house.
    On another note our four year isn’t spooked and upset by these alarms as it tells what is happening before a test etc.
    Very happy with these alarms, slightly expensive BUT I don’t believe you can really put a price on safety when it comes to your family.

    Brilliant, I added this upstairs to my existing Nest System, as I have one of these alarms downstairs.

    Seamless in operation, attractively designed, superbly constructed and innovative and effective in use, so much more than a smoke alarm.

    The Self-Test facility is brilliant and amuses visitors kids when it activates and the fluorescent LED Halo Night light so cool. It even tells me when the toast is ready even though the kitchen donor is shut and the toast not actually burning, very sensitive but not in a bad way.

    All round brilliant and delivered very speedily!

    They look good and are easy to install particularly if you already have other Nest products. I like the fact they test themselves and they light up at night when you walk under them. The only downside is the cost and the fact that installing in the kitchen is discouraged but that is where the boiler is. We might have to get a separate unsmart carbon monoxide alarm for the kitchen or put a nest one somewhere just outside the kirche

    Very easy to place, install and set up

    App is easy to use and quickly gets units up and running

    The inbuilt night light is really sensitive however even on lowest settings provides enough light to light area.
    This can be easily turned off if unit on bedroom or not required in other areas.

    It’s loud! There is no way you’ll not hear this.

    Only criticism is the alleged 10 year lifespan….it’s from date of manufacture not purchase so if its been sat on Amazon warehouse for months your missing out on months (7 months in our case)

    Overall though highly recommended

    Golden Review Award: 2 From Our UsersDeclaration: I work for Google but I don’t have anything to do with these products and I’m not interested in promoting their stuff. I’m writing this as a consumer.)

    I bought these after moving to a new house and needing smoke alarms in the usual places – kitchen, bedrooms, near the boiler. They’re nicely built pieces of kit, and blend in unobtrusively on a white ceiling. They’re actually stylish for what they are. Other manufacturers don’t seem to consider that these things become part of the decor.

    Setting up was a little tricky as they failed to connect to the wireless network I’d set up. I managed in the end by connecting to an alternate network but the message was cryptic and all I could find was that it might be down to DNS or maybe uPNP. This completely blocked the setup for a while. Some clues at least in the error messages would be good. I know the trend is to have things that hide the technical details away from the end-user, but this just caused inconvenience.

    They come with good quality batteries already installed, and the mounting bracket is easy to fit. It allows you to make small adjustments to make sure it’s straight compared to the line of the walls. It’s quite robust and I only needed a screwdriver. There are screws included.

    It’s an effective smoke alarm. It performs well, it’s loud and the app connection works as it says it does.

    There’s only so much you can say about a smoke/CO detector. Here’s hoping it sits and lasts for ages so it can justify its cost.

    I bought six second-generation detectors. Amazon UK prices are lower than elsewhere. I’m happy with these detectors even if they are among the most expensive on the market. They are very easy to install, they are interconnected: i.e. they all emit a signal in case of a smoke alert and can be configured by giving them a label each one so that they indicate the place where the smoke comes from. Two problems: generation 1 was planned for a lifetime of 7 years, 5 have problems with battery consumption after 5 years and these stupid engineers have changed the fasteners and especially the holes in the fasteners between the first and second generation: non sense.

    ot the cheapest but the overall functionalities and quality make it worthwhile. Super easy to install – does regular tests and informs you about it through the app. Lots of extra features (nightlamp – home/away function – regular automatic tests – indication of smoke/fire – ability to detect steam (handy if you have it installed next to a bathroom of kids ;-)),… Would definitely recommend it!

    Have been using this for about a month. Seems to be well adjusted – starts the alarm process not-too-early, and works through “There’s smoke in the Kitchen” to “Smoke is getting thicker in the Kitchen – the alarm will sound” to “Alarm” in controlled steps. Frying bacon evokes the 1st level – turning on the kitchen cooker hood stops the process. Alarm status and controls are passed through to a smartphone. Have not tried to sync multiple smartphones. Yet.

    Golden Review Award: 3 From Our Users**Edit 2** over 2 years since purchase, still using the original batteries! Nightlight still on Medium! Very happy!

    **Edit** 10 months on, batteries still going very strong 🙂 Nightlight still set to Medium!

    Nest are quickly becoming a household name in the Smart Home sector and these Smoke Detectors prove why.
    Ridiculously easy to install, setup and test. We also have the 3rd Gen Learning Thermostat and they work seamlessly together in the Nest App.

    Having slight pyrophobia (fear of fire), these put my mind at rest and I know the house is safe even when I’m not there.
    The night light feature is great and saves turning on lights that wake the household. We have the light level set to Medium and the battery is still going strong. (Important to note that you must use the Energizer Ultimate Lithium AA (L91) batteries for a guaranteed performance).

    Not only are they functional, but they look great too and remind me a bit of a Wireless Access Point. The battery feature saves you having wires trailing everywhere or having to route them through the ceiling – great!

    After reviewing this product thought I would bite the bullet and buy one . Was very easy to set-up , this needs to be done really before you fit it , and easy to install as well .Like the look of it compared to other smoke alarms , looks far more modern . We all love the night /safety light feature that illuminates the landing at night as it senses up going upstairs . Will definitely replace my other alarms now for Nest .

    Great product. Purchased as I was and still am turning the house smart room by room after re decorating. I have this mounted in the hallway which is joint to the kitchen and I must say it works a treat. It’s not so sensitive that it goes off each time I cook but sensitive enough to know that I’ve burned toast as I frequently do lol. I would like to see some added features from nest such as the ability to use its motion sensor with Philips hue. The Philips hue warning lights are very much delayed tho by approx 30secs but I’m not fussed about this as you can still hear the unit which after all is what a smoke alarm should do. The night light is a great feature especially when coming home late from work or just getting up in the night to grab a drink without blinding yourself with main lights. Delivery was very fast. Over all very good and little complaints about it from me.

    Expensive at first, but the best detector out there. Why gamble with a cheaper one, especially one that isn’t networked? Major feature is the nightlight – I’d have needed a movement activated light there anyway and this saves buying a separate unit. If it didn’t have that, it would still be good, but I would have thought twice about it. Looks good, does exactly what it should, cannot fault it.

    This stylish product is simple to install, and has a number of very useful features. Especially no more being woken by an alarm with a dying battery at 3:00 am. The units issues warning on the status of the battery, the presence of smoke prior to the alarm going off, and the need to check regularly that the unit is functioning properly. Thee mobile app provides remote warning sand control. In the dark the built-in motion detector provide sufficiently illumination for safe passage. Expensive, but recommended

Plays nice with the Nest Thermostat and the combined Monthly Nest Home Report includes not only energy usage but an overview of what the Protect has been up to over the past month. Considering getting a second.

    Golden Review Award: 4 From Our Users…according to Which? consumer magazine and they test them extremely thoroughly. Not only are they very sensitive to all types of fire (as well as carbon monoxide), because they link together via WiFi, activating one will activate all on all floors giving you much more time to escape (e.g if you’re in the attic and there’s a fire in the cellar). Ours have never gone off inappropriately but smoke from a hot oven in the kitchen was enough to very rapidly trigger the alarms in the hall and landing a considerable distance away. They do give you a verbal warning before going off which is sufficient time to cancel the alarm if you’ve just burnt the toast etc. There’s also a handy motion sensitive night light – provides just enough light to find your way to the bathroom without completely waking you. They even call your mobile to tell you your house is burning down while you’re away so you know to make alternative arrangements for your return and plan a funeral for the dog. Only downside is they’re not cheap but that’s trivial for the assurance they provide.

    I already had one Nest, but needed to replace my other smoke alarms which had gone past their use by date. Got three of the nests. Very simple to set up, just follow the app, as I already had one set up it just used the same settings. Gave them all a name and then fixed them to the ceiling. The ring is fixed with four screws that go straight into the plaster without any issues, felt firm afterwards. Then fix the alarm to the ring.Now when you test one alarm it automatically tests all of them.
    They look very smart, much better than a normal smoke alarm. They are also all connected together so if one detects smoke, they all sound and tell you which one has detected smoke (or Carbon Monoxide).

    I was a bit put off by the cost, but as my old alarms (non CO2) were well overdue for replacing, I already have a nest thermostat, and am in the process of automating my home, I thought I would give these a go.
    I have not been disappointed, and being able to mute the alarm when it’s cooking mid-haps triggering the alarm is great as we have a young baby at home. They also came in handy when my wife managed to set the kettle on fire whilst I was next door and was able to run home and investigate.
    As one might expect, the night light feature has been the most used, and is great for avoiding tripping over the car when stumbling to the kitchen to make a bottle in the middle of the night. It’s not so bright that it wakes you up, but provides just enough light to see where you’re going without having to fumble about for a light switch.
    Overall they’ve been a great buy and will hopefully prove value for money over their 10 year life.

    I’ll leave all the techi reviews saying how splendid these bits of kit are, and just say that although these are regarded as pricey by some, for such excellent safety in your home, it is really worth going for the best.
    However, this review is about good Customer Service, which is so rare these days. I bought three of these units; two to start with and then a third for a new extention which housed a boiler. One of the alarms started to ‘eat’ batteries needing three sets in five months, whilst the other two are still going strong on the original supplied batteries. I contacted Nest Support. A new unit was despatched quickly and the return package was prepaid. I received a pleasant telephone call from their Customer Service department clarifying the return and everything was done professionally. In the unlikely event that you get problems with a Nest product, you can be assured a splendid support.

    They seem pricey in comparison to the usual ones but you get a quality product. I live in a tall terrace house with a basement kitchen and I was never sure if the original alarm would wake me at night. So, as these ones are linked together, I can now be alerted in my bedroom if there is a smoke/fire in my basement or living room and told where it is. Might have to buy an extra one for the top floor.
