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.

    This is very expensive but my house is much more expensive. I did buy 6 of these to cover all spaces.
    Why risk a house for a few quid with cheapies that may or may not work when required . This unit fully self tests and reports via the smartphone app. One nice feature is to inform friends/neighbours of a fire.
    Read the specs it says it all, and read the internet reviews, no point me repeating it all.

    Love this (night light, app, speaks to you, warnings, testing) except for one thing…it can’t tell the difference between smoke and my bathroom door being open after a shower. Never had this problem with any other detector and it’s in the same place. At least I can jump high enough to turn it off!

    Golden Review Award: 20 From Our UsersI pondered for a long while over whether to buy these as they are anything but cheap. In the end, I decided that our life was more important than the six hundred pounds which is what I spent to put a detector in every room. They do just what I wanted. When my wife burns the toast in the kitchen, the detector in my office in the attic, and every other room announces, “There is Smoke in the Kitchen, the alarm will sound”. My phone also activates. My wife cancels the alarm in the kitchen and opens the window and the detector then announces, “The smoke is dissipating in the kitchen” and then eventually, “The smoke has cleared”. At night when I move through the house with the lights off, the detectors illuminate spreading enough light for me to see where I’m going. As an electrical fire can trip the mains power, this facility provides emergency lighting which could be a life saving feature. Once a month the system does a self check and sends a report to your phone. This has given me peace of mind and as the money spent has long been forgotten, I am so glad to have these in my home, especially as my wife and I are growing older.

    These are really great and well worth the price tag in my opinion. Fitting is fine to do yourself with the mains power as long as you pay attention to the instructions which are very clear.

    The most annoying thing is the absolutely tiny QR code that needs to be scanned. My phone camera had trouble focusing on such a small code so it took several minutes.

    These are extremely sensitive, and are set off by the tiniest smoke from cooking, and any kind of vape smoke, so bear that in mind if you need them in a particular place. They are also set off by steam from the bathroom, but only if you have a bathroom with no extractor or window you can open.

    The best feature is the night light which comes on for you when stumbling through the hallway at night, and is enough light to see, but not so much to be annoying.

    I installed two of these with no problems at all other than the QR code issue. The phone app is great and easy to use. They will last about 10 years, but all smoke alarms will stop working after this time because of the half-life of the radioactive element used to detect smoke, not because they want you to buy a replacement.

    Fantastic product. I bought the three set and have in the most important areas for full coverage.
    Here are the pros:
    Great packaging
    Incredibly Easy to set up
    Work together – when the alarm goes off they all respond so you hear it across the house. Voice alerts mean the system ‘tells’ you what the problem is and where the problem is
    Great app – you get the alerts on your mobile device in real time with a history of events – you can add people so they also get the alerts.
    Easy to physically install
    They look fantastic
    They self test based on a schedule you set

    Here is the con:
    They are pricey. But you get what you pay for and what price peace of mind?

    Golden Review Award: 5 From Our UsersUpon opening the product I was disappointed to find no supplied wall plugs, but quickly realised they were self-tapping screws of decent quality. Installing the back plate was a breeze, and you don’t have to be super precise with the alignment with any nearby walls as once the detector is attached it can still be rotated for finer adjustment.

    The companion app is okay as far as smart home apps go, although it had trouble with my postcode format despite my location being set to UK. I ended up punching in a postcode I knew from a few miles away, which it accepted. I don’t want my smoke alarm knowing where I live anyway.

    The rest of the setup was painless and once the initial self-test was completed you’re not really left with anything further to do. The alarm is loud and very similar to a non-smart detector alarm sound.

    The (default setting) pathlight I found initially underwhelming, but it comes into its own in pitch-darkness. It’s still very dim, but going from no light to some light is a useful feature. I’m really not sure how effective this would be in a smokey atmosphere, and hopefully I’ll never find out, but in my mind I see this as an everyday convenience rather than a selling point safety feature.

    100 does seem a bit expensive for a smoke alarm, but to be honest I didnt get much change from 50 when I last bought a ‘dumb’ smoke and CO detector. If it lasts the rated 10 years, that’s 10/year + batteries, which is really not a huge price to pay for something that could potentially save your life.

    I really like the fact it self-tests regularly and will report any problems automatically. Admittedly, my other smoke alarm only ever got ‘tested’ when I burned the bacon or made teriyaki chicken, so if you can put a price on peace of mind you could make the argument that these detectors are good value.

    I’m going to see how this detector goes, and as long as it doesn’t eat through batteries I’ll probably end up buying another one for upstairs based on my experience so far.

    So far, so good.

    Update: I had this a few months now and still going strong. But one thing I don’t like is it seems silencing an alarm from your smartphone has to be done via Bluetooth. I don’t have Bluetooth enabled on my phone, so this is a pain, and it’s actually easier for me to reach and press the button on the alarm itself. A nitpick maybe, but worth mentioning.

    Golden Review Award: 4 From Our UsersHaving had a Nest thermostat for a couple of years and a faulty smoke detector, I took the plunge and bought what could be the most expensive smoke alarm on the market.
    The Protect was easy to install on the ceiling, coming with a fixing plate and screws. It also comes with batteries, pop them in, connect to my phone and it ran a few tests, then it was ready to pop onto the plate and leave it to do its work.

    I love the fact you get a notification in the Nest app when the alarm detects smoke, it hasn’t happened yet, but if it did when I wasn’t at home I could check it out on my security camera and deal with any emergency there and then. It has happened when I have been at home though, with smoke from the kitchen while grilling sausages. You hear a loud voice from the Protect telling you there’s smoke, and in case you have multiple units, it tells you which room the smoke is in. This also comes up on the app. You’ve then got the option to silencing the Protect via the app before the full alarm sounds.

    The nightlight is another great feature, it’s not torch light but it is bright enough to help you see where you’re going late at night with the lights off. I’m not sure how powerful it’d be if the house was filled with smoke though.
    The unit performs a self test once a month to check its alarms are working (smoke and CO2), and lets you know via the app when the test is complete. It also checks it batteries and will notify you if they need changing.

    The most unusual thing about this alarm though? Never before have I had guests commenting about my smoke alarm. Even up on the ceiling its an eye catcher and a number of visitors have mentioned how good it looks!

    Golden Review Award: 65 From Our UsersDid I need a ‘smart’ smoke alarm? No. Did I see this and then try to justify it? Yes.

    Nest seems to almost create markets for things we don’t really need. But these products are very well made, designed and thought out. Our carbon monoxide monitor had expired, so I took the opportunity to purchase this after reading some reviews claiming the sensors it uses are really good. I wanted something reliable I could mount and not worry about and this certainly seems to be the perfect candidate.

    In the box, you’ll get a user guide, the Nest Protect, a mounting plate and some screws. It’s as simple as you’d expect and takes about 15 mins to install. The unit itself feels very sturdy and well made and is quite nice to look at.

    Fitting – I opted for the battery model as the Nest will let you know once batteries are running low, and I don’t have the wiring for a wired model in place. I was mounting this on a plasterboard ceiling so personally, I didn’t feel the screws alone offered enough stability. I’d recommend fitting with some wall plugs if you have a plasterboard ceiling too. 6mm wall plugs (red) will offer a nice snug fit. Note that the Nest Protect can be rotated on it’s base to lock it in, so you don’t have to get the base mounted perfectly straight. It’s also worth noting that it’s a pretty big device, so should cover up any screw holes from a previous fire alarm nicely.

    Setup – Just download the app, create an account and scan the barcode/enter the serial. It’ll carry out a test and then it’s good to go. The alarm is much louer than my previous fire alarm which gives you the confidence of it being clearly heard.

    App – The Nest app is nice and clean and as expected, allows you to control the settings of your Protect. It has a log of when it has carried out checks, been activated etc. The protect also has a nice little light that is automatically triggered on it too which is perfect for hallways and landings at night. You can control the strength of the light via the app (min/med/max). As it’s LED I don’t suspect it’ll reduce battery life dramatically. On the app home screen, you get a nice green indicator to show all is OK. You can also use the app to schedule the monthly check the alarm runs itself. It’s a shame you can’t fine tune the time (it offers windows such as 7am – 11am), but it’s a reassuring feature. As is the fact that you can be notified if the alarm goes off remotely which is the major selling point of this. One other feature I was really impressed to see was the option to have the Nest Protect turn off your heating if it detects a CO leak. This only works if you have a Nest Thermostat and whilst it probably won’t help much if there’s a leak, it may offer some precious time. This is a clear example of how much thought goes into Nest products and integration.

    I can’t comment on battery life and since it uses alkaline batteries, it can’t monitor how much is left. I assume it will let you know when it is close to running out though. It’s worth noting it uses long life batteries (included) so bear this in mind when replacing them.

    Overall, I’m very impressed by the device so far. My only reservation is the price, but when you factor Nest claim it ought to last 10 years, it’s an investment. And the price covers Nest’s costs to offer you that 10 years worth of updates, monitoring via their servers and support. It does feel overkill for what you need, but you’ve probably made your mind up about it if you’ve got this far!

    Protect your nest!

    Golden Review Award: 2 From Our UsersWe bought the old model 4 years ago and it randomly went of at 3am and wouldn’t shut up – I gave Nest a call for some advice and it seemed the unit was faulty
    It was 4 years old, 2years out of warranty. Without even having to ask they offered to still replace the unit free of charge and upgrade it for me at the same time – despite the fact it was out of warranty

    This is the second time we have used their customer service – both times it’s been exceptional and can not fault them at all

    We received our replacement (for free) and I bought a second unit, we also have the nest thermostat. All just Work and give you the peace of mind you need

    I would highly recommend one

    Golden Review Award: 26 From Our UsersI found a Youtube video to watch whilst I was waiting for these to be delivered so knew how to remove my old smoke detector and what wires i’d be needing to use.

    Upon delivery of the 2 x Nest Smoke detectors, I grabbed a flat head, philips (posi) and small flat head screwdrivers along with my step ladder.

    ENSURE YOU TURN OFF THE POWER TO THE SMOKE DETECTORS *NOW*

    Install the Nest App from your favourite app store, turn on the smoke detector and scan the QR barcode on the back using your phone’s camera

    Remove the old smoke detector
    Use the supplied plastic clips to join together the live, earth and neutral. I also had an IC wire (that sends the signal to the other detectors) which was not needed and the installation booklet just said to “isolate” this cable – Luckily I had some Wago clips lying around so used one of them on the IC wire.

    Then connect the 2 wires from the Nest smoke detector to the wires you’ve just unplugged from the old one, mount the new ceiling fixing and screw on.

    Push the button inside the blue LED and it starts to clearly speak to you.

    Job is complete.

    Had two to do, the longest thing that took me to do was remove the screw from the old one as it had cemented into the wall plug. Also showed the other shoddy work the builders did in this new-build home 🙁

    EASY ENOUGH FOR SOMEONE WHO IS USELESS AT DIY TO DO IN ABOUT 10MINS!

    I would have given it 5 stars if the installation wasn’t so flawed. The mains connector needs to go partially into the ceiling but for some bizarre reason, the connector is not in the centre of the unit but to one side. This means that you have to have a pretty large opening into the ceiling so that when you twist the unit to fit it to the bracket the connector sweeps a wide part of the ceiling, hence the large cut-out needed. I also found it difficult to fit the unit to the bracket on both my units, poor design.

    I bought two of these to replace some existing wired fire detectors that had started to malfunction. I must admit I think these are great. They look good, but I was surprised at the features on them. If you already have Nest thermostats then if these units detect Carbon Monoxide they tell the Nest thermostats to turn off the central heating boiler.

    They automatically self test (at a time you can specify). They link together wirelessly so you’re told which detector is alarming by name, ie “there is a fire in the kitchen”.

    But a great feature is Pathlight, which lights up a dim white light at night to help you find your way round in the dark.

    I’d recommend these to anyone, and easy to fit and configure.

    Must be one of the best products I’ve purchased in the last couple of years.
    Incredibly easy to setup, use and my smoke test worked flawlessly. The alarm beeped, turned on my lights and flashed them red to alert us as well as calmly speaking and telling us where the smoke has been detected. It then stays in an alarmed state after silencing ready to alert you again if the smoke does not clear. If it is taken care of further updates will appear on your mobile saying that the smoke is clearing. Then you get an all clear once the threat is gone.
    Coupled with the nest thermostat, it will also turn off the boiler if it detects carbon monoxide.
    Hopefully the alarm will never get used for real, but I’m happier knowing it’s there to protect my family and I.
    Love it!

    The best smoke alarm ever, look no further, you've found it!

    I bought this to replace 2 mains smoke alarms which needed replacing. These are great products let down by one small problem; the lead that connects to the power sticks up passed the base, which makes installing more difficult than it needs to be. I had to widen the hole in the ceiling quite a bit or i couldn’t twist the unit onto the base. I did like the connectors it came with, and once installed the smoke alarms are great. I like being able to monitor them on my phone and have linked them to my SmartThings Hub, so it smoke alarm go off the it automatically switches on lights. I also like it lights up the floor at night. I will be buying some more to replace other smoke alarms.

    Golden Review Award: 6 From Our UsersI love these. So you are thinking as I was, that is an expensive toy; especially when you can get a smoke alarm for under 10. This, however, is a key part of your smart home protection. The key thing is that you have active monitoring of the location you put it, wherever you are, via the app. You get status alerts for everything and it hooks in with your nest cameras, so if it notices something, the cameras come on too. So, apart from the peace of mind of knowing that your sensors are working, you can have these act as night lights. No need to have a separate hall light for that trip to the loo at midnight. These give a gentle light to guide your way. This light isn’t harsh, it is good enough for you to see your way but not to burn your eyeballs out of their sockets. This nice feature means that I can turn all the lights off downstairs, then go up to bed without having to turn the lights on, these helpfully light my way. I have had battery ones for just over a year without changing the batteries. However, now that I love them (and have bought 4 more), I have gone for wired ones and am using the battery ones in awkward places, like where the boiler is, for extra security. These are great but best to get the whole package (cameras, thermostat and these) for the investment to truly make sense.

    What can I say? Well I bought the 3 pack as they offer better value for money and all I can say is I’m very very pleased with them. Install and set up was a breeze, The Nest App is great and with a excellent interface and so easy to use and I was so impressed with the Alarms that I purchased the Nest Indoor Camera too and that is amazing. Yes they are expensive but seriously you cannot put a price and yours and your family’s safety

    Golden Review Award: 2 From Our UsersExcellent product, easy to setup and the app works really well.

    A slight cooking ‘mishap’ created a bit of smoke and the nest protect closest to the kitchen detected it quickly and responded with clear instructions/warnings. It then relays the warning to any other nest protects on your network and tells you exactly which nest protect has detected the smoke.

    It’s reassuring to know that you can get a notification wherever you are, as long as you have a data connection. It’s also reassuring that the nest protects do self checks of all their functionality, especially the battery check as it takes the guess work out of when to replace batteries, if you opt for the battery version.

    Looks great and feels a lot more reliable than the cheap ones I got before. One of the previous ones would occasionally detect carbon monoxide even though my flat doesn’t have burning heating or other risk factors. Anyway there was nothing to query after the fact, and it was difficult to tell what had been detected. In this case you get a continuous log from your Nests and I feel more confident that they will work.

    Of course the real test would be with actual fire or carbon monoxide, and who knows how it would behave in that situation… But given the craft and engineering that obviously went into this, I feel more confident than with the cheap ones.

    This is so good compare to the normal smoke alarms! It gives you a heads up when it detects smoke which the alarm won’t suddenly go off. It also gives you a history in the app with time smoke was detected and it was cleared etc etc. You can control the alarm using the app so you don’t need to run to the smoke alarm and try to reach for the ceiling to turn it off.

    It was very easy to install! Doesn’t need a drill at all and you can screw the backplate any way you want and when you attach nest protect you can have it in the angle you want.

    The pathway light is such a lovely little touch too!

    got three of them one for each floor.

    I cheated and set them up using a couple of bus bars wired to a socket. And didn’t pull the battery tab when told to.

    They must be the easiest smart thing I have set up so far.

    Create the account add he first one, link to wifi and then add the rest. test and your done.

    Added bonus is that because the battery isn’t connected yet it tests out the alerting system because you then get a message saying battery low.

    Tested them with smoke and steam and it works a treat. CO again was good.

    Night light is a brilliant feature means that when I go into the basement I get a light to find the light switch.

    Golden Review Award: 10 From Our UsersI have two nests which I bought once I realised the normal smoke alarms that I had were expired and not actually working. I hadn’t even thought to check until recent news stories brought it to my mind.
    The great features about this are:
    – The Nest talks to you and explains what’s happening and where (smoke has been detected in the kitchen etc)
    – It keeps you up to date for example if the smoke clears it’s tells you the smoke is clearing
    – The sound if loud and very clear, it would wake you if you were asleep
    – It runs weekly tests that you can schedule once and leave it to do, it announces that it’s a test before hand so you know it’s coming.
    – There is an app that you can link to so that you can silence the alarm instead of trying to climb up to the ceiling. You also get notifications when a test is complete or an alarm has triggered so if you are out of the home you know what is happening.
    – there is a night light with a motion sensor that can be activated or deactivated, it’s great for in the middle of the night if you or a guess is walking in the corridor.
    – You can link the nest to other devices; I’ve linked mine to my smart lights so that if there is an alarm they automatically come on to help with visibility and to wak the house up.

    Golden Review Award: 4 From Our UsersI love this product, my intention is purely for the remote alert of any fires, one that only alerts those in the house is only doing half the job especially if you have kids or pets. My only negative is the test doesnt include the message alert which i need so i had to create a small fire in order to test its function with my phone ( i do not recommend doing this in any way and have reported this to Nest to hopefully see them update this as a function on their app )

    Quick easy installation by an expert, smart and clean looking. App is easy to use and I love the light that comes on at night, first green to tell you its working and then white when you pass by. The light is like moonlight so great for a night time visit to the “powder room”. I would highly recommend this product (based on that but have not had a fire/smoke or carbon monoxide set it off yet!)
    I wonder whether you can turn off the light function (the white one) as one of the alarms is in the ceiling over a guest bed which comes on whenever we have guests that turn over in the night!

    I have now got 3 of the battery-powered units installed. Have to say that installation and set-up was an absolute doddle and took only a few minutes with clear instructions provided both with the unit and via the app.

    Gimmicky? Yes, a little. But also extremely functional at the same time.

    The ability to check the units’s self-test history, initiate a test and even check at what times the pathway lights came on during the night, all from your phone, is a boon.

    I have been converted and have now bought a Nest Thermostat also which is being installed next week so will be interested to see how it integrates with the Protect units.

    All in all, I can whole-heartedly recommend this product.

    Awesome product. Easy to mount and install, easy to set up.

    Only issue I have found is the Software. There is no possibility to update the WiFi for the Nest Protect, you have to remove them from your account, and re-add them.This is quite annoying as you have to detach them, rescan the code on the back, add them to your account again, etc.

    Golden Review Award: 10 From Our UsersIf only all technology was like this…super-simple set-up requiring no written instructions really. Just install the Nest app on a smartphone, scan the QR code on the back of the device with your smartphone’s camera, and follow the instructions on the app. Up and ready in less than 5 mins.

    The functionality just makes sense – a yellow light appears when there is something that needs attention, and a red one when an urgent situation (smoke or CO) arises. The alarm is loud and can be stopped easily by just pressing the front of the device or using your smartphone. Voice instructions are also given.

    I have bought Nest cameras because they similarly “just work” straight out of the box and are extremely reliable. I’ve given up on other brands which had multiple connection or versioning issues.

    I wouldn’t waste your money on anything else. This is expensive but worth every penny and the materials look liie they are built to last.

    We had one of the mains powered units in our house, and a feature we liked was the pathlight feature, so got another to use on a hall way between our rooms. Battery life seems good so far, however an exact reading isn’t given (we’re about 2 months in with full brightness on path light, fairly regularly used and still ok on battery). Dead easy to setup as it grabbed all the settings off our other nest, the apps simple to use and the system really just takes care of itself. installation was simple (backing plate and 4 screws straight into plaster), with an easy twist method to release the nest when the time to change batteries comes. Very happy.

    Like the idea which I hope I never have to use, the only downside to the 240v model is the connection for the power protrude’s past the backplate & is not central so as you turn the unit onto the backplate you have to cut a bigger hole in the ceiling to allow the unit to turn into position.

    Golden Review Award: 2 From Our UsersI love my little network of Nest smoke/carbon monoxide alarms. They work perfectly and look great. Last night I was grilling lamb chops and the coloured ring changed, the voice calmly announced that smoke was detected in the kitchen, the alarm might sound and that it would be loud (bless). The alert also popped up on my phone. Doors opened, extractor cranked up and my phone message said “smoke clearing in kitchen”. Absolute genius. These are expensive but in my view they are worth it. Just make sure you get the wired one as the battery only doesn’t conform to building regulations (which begs the question as to how it is able to be sold).

    Golden Review Award: 5 From Our UsersAfter getting one of these through a special offer from my insurance company, I decided to go the whole hog and fit one on every floor. These excellent, compact sensors which were easy to set up and link to the app. The app is easy to use and the sensors seem reliable. I like the fact that the units show a white light when movement is detected close to the device and the lights are off. A good safety feature.
    Only one point to be aware of – the connector for the incoming mains wires protrudes considerably beyond the back of the sensor so you need a much bigger hole in the ceiling to avoid damaging the cable when the unit is twisted onto the back plate. Not a great design, especially when the wiring has previously been installed through drilled holes in the joists above.

    Golden Review Award: 19 From Our UsersWe already had wired smoke alarms, but they were over 10 years old.
    Upgraded to Nest Protect to get CO alarm for extra protection as well, our first foray into the smart Home world.
    We did the install of 3 linked alarms ourselves using our existing wiring (we are reasonably competent at electrical diy). Installation was straightforward once we’d worked out how to remove the old alarms. We were fortunate that our old alarms were mounted on a socket back box in the ceiling. The nest back plate is round and has numerous mounting screw holes which made it easy to line up the back plate with existing holes. Be sure to install the app, start up and add your alarms to the app and link them up before mounting them in their final resting place.The alarms then twist onto the back plate.
    The alarms do a self test on install.
    The instructions supplied are very good and it is a fairly straightforward process.
    It is quite reassuring to see the light ring glow green when the light is turned off at night to know that all the alarms are working well.
    The light ring also provides a night light (white) that comes on with movement so that you can see your way without turning the main light on.
    The warning voice and subsequent alarm are reasonably loud, we have then in the hall and on the landing. Won’t be installing them in other rooms/bedrooms.
    The Nest products will work with some smart light bulbs, it is possible to set it up to turn these lights on if the alarm goes off.
    Through the app you can check that all your alarms are working ok, and see the last self test info, they test themselves numerous times a day. The alarms also do a full voice test once a month and report back as well.
    If there is a problem when you are out/away you will get a notification, which means that you can either pop back home or get a neighbour to check for you, an additional protection for your home.
    They are expensive, but for the additional features to a standard smoke alarm do make it worthwhile, these products are new and at the cutting edge of smart Home technology but also easy for a competent diyer to install (saving on installer charges).
    Buy with confidence and enjoy a better protected home.

It beeped and announced there was smoke in the dining room and continue to flash a red light. I was able to silence it by pressing on it but the red light continue to flash for several minutes until the smoke had cleared and it went to blue and then off. Upon looking at my iPad some minutes later it had also sent several messages but I was in already in the smoke-filled room .

    I have this along side Nest Cam in my hallway, installation and setup were simple – just follow the instructions and you’re ready to go in 5 minutes. Self testing and updates come through to the App on the phone or you can access it from the internet. Thankfully I’ve not had to test it for real but I’m sure it’ll do it’s job. The lighting indicators are a great way to tell at a glance if everything is good and the night light is a nice touch.

    Very much the “Apple” ethos in terms of materials used, build quality and packaging. This was my 2nd attempt with Nest Protect after an aborted attempt to connect a pair to my home network failed miserably a year or so ago….despite many friendly chats with Nest Support, we couldnt get them to join the network. I now have a new router (TPLink Archer vs the previous Asus Dark Knight), so I took a punt and bought another one. Worked like a dream, hooked up within 30s, so ordered 5 more (so far), and recommended to my Parents who bought 3. The only thing to be aware of is that for the mains powered ones, you do need to cut a decent sized hole in the ceiling to lose the electrical connector blocks that you need to use. A decent hole saw makes light work of it, just make sure positioning is spot-on first. Both my Parents and I love the pathlight feature (can be disabled for bedrooms) where it detects movement, and dark, then will light the halo up in white to just give enough light to navigate around; saves switching on a bright hallway/landing light during the night. I also have Nest Thermostat 3rd Gen, which interacts with the Protects in the event of an alarm condition, to instantly switch off central heating and HW. Smart.

    Golden Review Award: 3 From Our UsersYes it’s expensive for a firealarm, but lets be honest you can’t put a price of your safety right !! Anyway. Easy to install if you have a current wired fire alarm. The system itself comes in a box with all required bits and bobs for install. It’s easy to install yourself, just make sure you switch off the current firealarms from the mains. Install should take around 15 mins per alarm. Once installed it’s a brilliant bit of kit. Warnings are clear, giving you plenty of time to act on them (my wife love cooking pancakes and is regulary smoking the kitchen out, newt gives us a warning there’s smoke and that we need to act on it or she’s going to set an alarm off, the beauty is also that it warns you on other Nests as well. So if she is smoking the downstairs out I hear an alarm on the upstairs one letting me)

    Cannot recommend this enough.

    Golden Review Award: 2 From Our UsersI took the plunge and purchased one of these smoke / carbon monoxide detectors a few weeks ago to replace my old smoke alarm and portable carbon monoxide detector. Yes you pay a small premium for this type of gadget but certainly don’t mind when it is this good a package and outweighed by the safety features.

    * I was very impressed with how easy it was to install. I expected it to take 15mins+ but was installed in less than 2 minutes and setup ready to use 2 minutes later! I do love my gadgets and happy to tinker with them to get them working but was wish every setup was this easy! Nest have led the way, it really was as easy as 1,2,3!
    * Once you register with Nest, an app is used to monitor and setup the device.
    * The alerts include such gems as “Warning, Smoke detected in the kitchen” I like this feature as it alerts you to 1) The cause b) The location, rather than just beeping.
    * The alarm notices that the lights have gone out and illuminates green to show everything is okay for peace of mind.
    * And if it detects movement below it, the status light changes to white and provides enough white ‘glow’ to provide a night/escape light. I really like this feature, as it provides enough light to get me up the stairs without another light source being used.

    Overall very happy with this alarm and recommend it to anyone.

    Firstly, the un-boxing was a treat since the packaging and presentation are glorious. Installation was a breeze for anyone who can screw a screw and operate a smart phone. The only issue I have with this product is whether I can rely on my home and mobile data connection to tell me that there has been smoke detected.

    A little bonus I noticed the night after installation was that it detects motion at night and puts on a courtesy LED. Nice touch.

    For my money this product is worth the premium over a regular smoke alarm though I do still run the old alarms as back-up.

    Golden Review Award: 12 From Our UsersIt works brilliantly! No more waving a tea towel at the smoke alarm when cooking and no more testing with the end of a broomstick.
    The unit was however far trickier to install than I anticipated. Other alarms I’ve used have always had a space in the back to house the wiring. This unit doesn’t, so the wiring has to be hidden away somewhere else. This required me to chisel away a significant amount of plaster work on my ceiling and made it very difficult to make everything fit.

    This is exactly as expected and in short, excellent. Very easy to fit and child’s play to setup, it really is. Yes it seems expensive for what it is but it is just no fuss and does not go off at the slightest nat’s fart!
    It did recently trigger due to smoke from cooking and the whole process was amazing, no screaming alarm to make you need to change your pants, but a mellow ‘pre-warning’ voice that the alarm has detected smoke and will likely go off which was then simple to silence. Oh and that was all backed up with a notification to all the phones connected to it.
    Would I buy it again, absolutely without a doubt, in fact there is another sitting in my basket right now to replace another make of alarm for another part of our house.
    Having both smoke and CO2 in the one device is just the cherry on top of the cake.

    Golden Review Award: 100 From Our UsersWhen I was woken at 3 a.m. the other morning by my smoke alarm complaining that its battery was running low, I decided it was time for a more sophisticated solution. And this is — at so many levels.

    First, the physical features. It may sound strange but it actually looks nice. Mounted on a ceiling, it doesn’t shout out its presence but, to the extent that you notice it, it’s quite attractive. So far as fixing is concerned, you don’t have to line up the backplate very precisely because, once you’ve aligned its lugs with those on the alarm, you can turn the unit as far as you like. Also, the unit is supplied with self-tapping screws that need no pre-drilling to mount it in a dry-lined wall or conventional ceiling.

    Next, the set-up. This is a breeze. Download the Nest app to your phone, follow the instructions. You’ll need access to the back of the unit, because the app scans a QR code that’s located there to register the device. But it automatically launches your camera to do that, so it’s a doddle.

    Finally, the operation. I won’t list all the Protect’s features, which are pretty exhaustive, and can be found on any of the technical review sites anyway. Suffice it to say that the app is well-designed and reliable, allowing you to control and respond to the alarm from your phone. So, for instance, you can do a monthly test by hitting the ‘Protect’ button on the app home screen and following the prompts. This will update the log, so you can see the dates and results of all previous tests. There are also some nice little touches. The light ring around the alarm’s central button lights up (white) if you walk under it in the dark; and it gives you a brief green glow when you turn the lights out at night to confirm it’s functioning correctly.

    So is it worth it? Well, you could buy half a dozen standard CO/Smoke alarms for the same money. But they only warn you of a fire you’re close to anyway. This will tell you there’s a problem at home wherever you are and what room it’s in, if you have several installed. And it will launch your phone app with the emergency number pre-selected for a quick call to the fire brigade. That’s a lot of reassurance for 25p a week (based on a 7-year lifespan), quite apart from the sheer convenience of the thing. As with any insurance, you pays yer money and you takes yer choice…

    I have two wired and one battery nest protect. I really trust these alarms and they all integrate nicely together and work well with the app.

    I do wish on alarm a text message and alarm would trigger on your phone. You do get a notification via the nest app but it’s not in your face enough considering your house could be burning down.

    Excellent product, does what it says on the tin. Bought to replace a system on three floors, comprising smoke, heat, and monoxide, now all three look for all. The setup is easy. My only criticism on the device is the nightlight feature, which is a good idea, but at the moment is too sensitive, it would come on even moving a finger. I contacted nest support and they responded saying they would consider an option to reduce the sensor sensitivity. The feature can be turned off, and is very good for halls, but found the issue with one mounted in the bedroom. I look forward to new products rumered to be in development, including individual TRV and door entry to add to the system. Would definitely recommend, is worth the money!

    Received in time for a quick setup and test, which takes only 10 or 15 minutes.
    Beware that you need to be able to give access to Nest to your network and allow the monitoring on-line. Not sure about security here.
    The device feels like a quality item. So it should, it’s expensive for a smoke and carbon dioxide detector.
    Nice to have a human voice warn you rather than a loud screeching beep. Also, a good plus is that there is no on-going monitoring fee, unlike Nests other devices.

    More expensive than a standard alarm, but well worth the extra money. It has some clever features, including connectivity with other Nest products. The Alarm was reasonably easy to install with very clear instructions. Be prepared to cut/widen holes in the ceiling to accommodate the wiring and connectors (if you choose the wired alarm). There is no room between the ceiling and the fixing plate/alarm to accommodate wiring. Also, as the shape of the Alarm is square and not round like most alarms it will replace, be prepared for a little ceiling painting to cover exposed areas. Like all nest products it is very stylish and beautifully packaged. It Arrived really quickly via Amazon Prime.

    Golden Review Award: 2 From Our UsersI ordered these after checking them out at my daughter’s house. Truly, they are five star products. So why only four stars?

    Because nowhere, not on the Amazon product description, or on the Nest website under “requirements” does it state that they require a broadband connection that supports the ipV6 protocols. Mine (PlusNet) does not support ipV6, so basically, the alarms will not work as intended. As far as I can make out, only a few of the home broadband internet service providers fully support ipV6, so many uk customers might well have to return their Nest Protect alarms as unusable. I have decided on a return as changing my isp and upgrading the modem is just too much hassle.

    I have to say that the support system is very good.

    Purchased 4 of the mains powered version and they were fitted by a qualified electrician as part of my house refurbishment.
    11 months on and they are still all working fine, I particularly like the adjustable night light feature which is great for the ones in hallways at night (can be switch off for bedroom ones, otherwise it comes on every time you roll over).
    Having switched routers a few times I have learned it’s easier to change the Router SSID and password to match the previous one rather than run round setting up the detectors each time.

    I bought a nest thermostat, so thought I would add this smoke/CO2 detector too. It’s pricey, but a good quality product. It was a little tricky to set up initially, and I had to have 3 goes at it. The set-up steps aren’t complicated, so you don’t need to be a techie, but for some unknown reason it didn’t work until the 3rd time. Once set up though it just works. I like the fact that it lights up when I walk past it in the dark. I think I will get a second one for the lounge.

    This device is perfect for what it’s designed to do. It’s helpful in itself, and the accompanying software from Nest for your phone or PC works just as well. It’s a nicely designed unit, substantail feeling with a great build quality. Installation is a doddle, providing you’ve already got the mains connection available for it to use. Pull out the piece of plastic preventing the batteries from connecting to the unit to power it on (do this BEFORE installation to the mains), and run through the setup process (the reason you do this before mounting to the ceiling is that there’s a QR code on the back that you need to scan with the mobile app in order to register the device as yours on your account). Voice prompts go through a test routine, and then it instructs you to complete installation. My old detector had 3 wires connected to it – Live, Neutral and Interconnect. Nest Protect doesn’t use the interconnection wire as it’s all done wirelessly, so that can be cut back and insulated. Simply screw the backplate to the ceiling or wall, use the provided connector blocks (which are also great quality) to make the relevant connections for the provided wiring harness to Live and Neutral. Plug the harness into the device and clip the device to the ceiling. That’s it!

    As far as day to day use goes…it’s just a smoke/CO detector. But so much more advanced than the cheaper tat you can buy. It self-tests several times a day, and when you switch the lights off the ring glows green to let you know everything’s OK. It’ll also activate a white ring which is a “pathlight” so you can find your way around in the dark.

    This replaced one of my old mains based smoke alarms, and I’ll shortly be buying another to replace the second one.

    All in all, highly recommended.

    The best thing I like about the unit is the curtosy nightlight on my staircase when I get up during the night. It’s not one of those strong lights but calm enough to light the way if required. It looks great , larger of course than your standard units, but certainly not ugly or out of place in any home. The fact that you can be alerted when you’re away is a massive plus too. A valued part of my smart home equipment. And it states replace by 2026 giving it 10 years of protection for under 90. A little price for such an item over 10 years of looking after my family don’t you think?

    I have been so impressed with this product that I went and bought 2 more. You can schedule them to run a full test at a time that suits you, so let’s say once a month between 11:00 and 16:00. The device check itself continuously and sends you a report on your phone. What attracted me to it was the fact you are able to mute it with your phone if it goes off. I got so fed up with being waken up in the middle of the night for a false alarm (often triggered by bugs or spiders getting into the smoke alarm) or because the battery was running low. The Nest Protect also acts as a night light and turns itself on when it senses movement near it. The lady voice is also a very cool feature. It relies on your WiFi when you set it up but then works completely fine without it, just in case you were wondering what would happen if the internet was down or you had a power cut and a fire starts. It also tells you whereabout in the house the problem lies. All in all, it is pricey but it is a very good product.

    I always check out a product for a while if it’s new to me and I did that here with the Nest Protect. I liked the features and what it does so ordered one and I’m not disappointed. From the moment you open the box it’s quality all the way with the packaging materials and the way it’s packed so neatly. The product itself just looks so good well constructed & finished off. Instructions are easy to read & understand & it’s simple to set up once you’ve downloaded the app. Just be aware it’s loud when you test it ok! & it’s the first one that’s ‘talked’ to me that all is good to go! The night light option is a beautiful soft sheen glow to aid night time visits to the bathroom, just brilliant! Plus this one doesn’t set alarm off because you’re using the toaster! Bonus points there!
    Get one they’re brilliant, yes they’re expensive but with longevity guaranteed & noticefication on your phone/tablet for alerts I think they’re worth it!

    I first purchased a wired version of this and thought it worked so well I had to invest in a battery one for the Kitchen. The alarms make it so much safer in the house. They pick up on smoke so quickly and give you a warning without going crazy. It will warn you on the alarm and then on the other just in case you are upstairs. It also tells you on your phone. If you don’t act or the smoke is thick it’ll go off, it will set the other one off to so super loud. I really like the fact that they test themselves and that you get a monthly report. They do seem pricey to start with but well worth the money for peace of mind. Also the light up feature for night time works great so you don’t have to use lights if you need to sneak to the bathroom

    One point to note is that it fits flush to the ceiling and there is no space for cabling – meant I had to hack a bit of plasterboard out to create enough space to poke all the wires up out of the way.

    Bought one as a bit of a test; second one now on the way and 3rd gen thermostat on order!

    My first NEST product and it’s impressed. Good product, great packaging, clear instructions and a nice high tech product. Only got 1 nest item to test but they should work together smoothly and there are cameras and thermostats that all run for the same app. Auto test function and feedback to app of status is a nice touch.
    A great smoke detector for a technology geek like myself!

    About me: I’m a dad of 2 and husband of 1! I give reviews on products that I’ve personally used. I started doing reviews in 2016 as I was fed up of reading reviews of products that didn’t reflect the real life use of the product or we’re just moans about things that were clear in the item descriptions and being made by incompetent people. Like my review if you found it useful and I’ll keep buying and reviewing products… thanks for reading…

    Impressed with this item fitting instruction excellent although it did take three attempts to link to system via blue tooth , I am going to extend as the clarity of the self test and the unforeseen benefits of the built in safety lighting added to the fact that it test for smoke and carbon dioxide make this unit good value have had for two months now and the monthly printout to I pad an added benefit .
    Will wait another couple of months and if performs as it is now will extend system and also install some extra members of nest family .

    Looks great, very easy to install, build quality is very good. This device gives me real peace of mind that my property is protected with push alerts if it detects anything untoward, so far nothing has happened and I hope it never does. I really love the nightlight function for when I get up in the night, it detects me and illuminates my way safely down the stairs. My only gripe is the price, for what it is it’s very expensive.

    Fantastic bit of tech – took less than 30 mins to install (apart from the plaster dropping off the ceiling when removing the old unit). The App is brilliant and goes well with my Nest thermostat. I bought 2 sensors (upstairs and downstairs). A bit pricey but it will be worth it if you get a CO build up or fire.

    Best features: Lights up the landing and the hallway in the night – senses people in the house when you are out – lets you know when the power goes off – remotely tells your App if there is a problem.

    Bought this for our first house.

    Packaging

    It’s clear that the guy who created nest worked at apple before.

    Everything about this product says premium, even though it’s just a fire alarm.

    Setup

    The first time I set it up, it was a breeze following the instructions on the app.

    Later I changed my home network and I ran into some issues. Nest support called me back to help and after long trial and error I found that having any devices on the network that contained a space in the name somehow caused an issue with the nest protect. Lesson learned.

    Using it

    It’s a fire alarm. Ideally you set it up and then forget about it. I occasionally check its status on the app.

    The night light function is actually super useful in my hallway upstairs because i frequently check on my young kids at night.

    Summary

    Looks nice, works well, nightlight useful. I like it!

    I wanted a smoke alarm that I could remotely turn off with my phone, before it went off and woke the dead – it works perfectly for this. It also integrates nicely with my other nest products meaning that I don’t have to worry about multiple apps on my phone.

    Slightly annoying that it’s not round – it does mean that if you’re fussy about appearances you need to put some effort into ensuring that you screw it to the ceiling square. With a little planning that’s easy enough – but the instructions didn’t provide many tips on how to get it square to the room.

    Easy installation and hook up to internet etc. Makes all the right noises and flashes lights. As a smoke and carbon alarm I hope i never need it to go off for real but seeing the product and having done the installation and tested it I have great confidence if there is ever a need for it to be activated I’ll get a warning which I will be able to hear and see!! Nice addition of a built in automated sensing night light too! Maybe a tad expensive but isn’t the safety of you and your family worth stretching the budget a little.

    Well having had a Nest thermostat in my previous house in the USA and now back home in the UK I just had to have Nest again, now have the Thermostat up and running here and needed a few smoke and carbon monoxide alarms to remain in compliance with today’s laws. Looked at Nest again and without hesitation purchased two of the battery alarms.

    Certainly not disappointed, now I know they are much more expensive than other alarms but these are classy, come with voice alerts, you can control on your smart phone and they test themselves, what more could you ask for.

    Placing them in the living room and kitchen was a breeze, check the pictures out.

    Will certainly be looking at the Nest Cam next 🙂

    Worth a purchase, even if expensive… Highly Recommended..

    We have indoor cats, so one of the things we always worry about is their safety when we are out of the house. This alarm was really easy to setup and the android app is easy to use. Is it expensive? sure if you compare it to a simple alarm, but the added connectivity buys a little peace of mind.

    We used some ‘no more nails’ strip to stick the alarm to the ceiling, which is preferable to drilling. There is a nifty automatic night light feature, which I am quite fond of. Unfortunately we could see from the android app that it was being set off 70+ times a night by our cats! You can easily disable that feature (the night light, not the cats). The alarm is also really loud. So far the batteries have lasted about 7 or 8 months. I would definitely recommend this.

    Actually, since this is my third I ought probably to say that I love it – once mounted. Herein lies the only reason I am not awarding 5 stars. If you are mounting the mains version (my first one was battery, so it is a doddle to fit) to a ceiling you will find that the mains cable is going to require more than a simple hole in the ceiling due to the fact that you twist the Nest Protect to its mounting bracket. Otherwise it is a fantastic product. Not cheap, but what price would you put on your own life, and those of your family?

    Golden Review Award: 47 From Our UsersHad a Fireangel Smoke Alarm previously, and it’s claims of 10yr battery life fell short by a factor of 7x (in the bin after 14 months). Decided to go for one of these, Yes, it’s quite a bit more the reason why I got it were:

    Replaceable batteries
    Wifi connected, so you will get alerts when not at home
    Carbon Monoxide detection

    Very impressed, very easy to install, and very slick operation. Feels like a massively high quality bit of kit. I already have a Nest Learning Thermostat which has paid for itself many times over, so it’s no surprise that Nest have made something as mundane as a smoke detector and impressive feat of engineering. Well done Nest/Google.

    2017 Edit:

    My original is still working excellently, given the recent tragic events, I decided to replace my other garbage (and dangerous) FireAngel with another Nest Protect, this time for the upper floor, where it’s easier to get to the wiring above, so I went for the mains powered unit this time around. The mains unit still has batteries of course for backup purposes (that’s a legal requirement). I have knocked a star off this time, a whilst the battery unit is for sure a 5 star unit, the mains unit has a design flaw. The mains connector on the tip of the unit protrudes from the base and is offset from centre, and as the unit is a twist to fit, it means you have to make a very big hole in your ceiling, the full diameter of the offset mains connector. They could have easily, i’m sure, made it either flush, or if not, more central to reduce the size of the hole needed in your ceiling whilst fitting. Aside from this, it’s still an awesome product.

    Golden Review Award: 3 From Our UsersI’ve had a Nest smoke alarm in the kitchen for a while and just bought a second for the upstairs landing. The kitchen one has ticked away working without any issues – I’m rarely at home when it does the periodic self tests but on the occasions when I’ve been burning food it’s given me an early warning before the main alarm sounds – much better than my old smoke detectors which would pierce eat drums at the faintest waft of smoke.

    One feature I never really noticed in the kitchen but is fantastic on the landing is Pathlight. I have it placed just outside the bedroom door and it casts enough light across the landing to make it to the toilet without needing to switch lights on (or tripping over things). I’m sure it will affect the battery life but fingers crossed not too much.

    Any my favourite thing about Nest Protect? It screws to the ceiling/wall with self tapping screws – life’s too short for rawl plugs!

    Previous reviews were confusing as they are a mix of 1st and 2nd generation reviews.

    Got mine and within 3 minutes it was up and running with an easy step-by-step walkthrough in the smartphone app.
    Also got the camera at the same time, this was also a 3 minute setup…

    It literally took me longer to get into the extremely well packed boxes than setup… which was a scan of a barcode on the device, select wi-fi from the list and enter the password, selecting a location in the home from the pre-defined list, and wait 20 seconds whilst it configures itself.

    I bought the unit for the open plan lounge kitchen diner, where we had no previous detection. Having a gas hob and real flame fire, the CO2 as well as smoke detection was an essential. This is a battery unit, the only downside has been the cat sets of the night light as it has taken to sitting below it; so we will see how long the AA batteries last. I have a Nest thermostat waiting to be installed with a new boiler system (moving from gas to electric) so the integation of heat and alarm means one system to monitor and control the house.

    Excellent piece of kit – this is actually the first review I have ever written, as few products have impressed me this much! Installed as a straight swap from my previous wired smoke detectors, seems very well thought through, from the setup, the warnings, a weekly self test, plus is much louder than my previous ones, which I see as an advantage for a smoke alarm! Love the fact that it covers carbon monoxide too.

    Notifications on my iPhone work perfectly, so am considering getting a camera to be able to check the house remotely too.

    Now strongly thinking about getting more Protects for the kids rooms, as seems a small price to pay for piece of mind.

  88. SashaWilkes says:

    We bought this smoke alarm primarily for the ability to receive notifications on our phone(s) if smoke or carbon monoxide was detected at our home in our absence.

    It’s a very clever unit that will self-test, warn you of slight smoke without the disturbance of a loud alarm (unless the smoke builds), and even lights up the hallway as you walk under it at night-time.

    A close second to improved family safety is the kudos you get when your smoke alarm politely and clearly warns you that it has detected a slight build-up of smoke when your friends are over; you may have burnt their lunch but they’ll forgive you for having such a cool smoke alarm.

    Purchased two units from Amazon as our old detectors needed replacing and as we own a three storey house we liked the fact that the detection of smoke/CO by one Protect will trigger the alarm on all other Protects on the same network. We were also attracted by the fact that we can check the status of the house when away from home. Installation and set up was as simple as the accompanying literature and online resources suggested. The app has a clean GUI and is simple to use. They obviously cost much more than a basis smoke detector but they are well worth the investment. Will almost certainly buy another unit in the very near future.

    The device is good, looks good, functions well and I’m generally happy with them. However; the base, connection lead and socket has clearly been designed by someone that has never held a screw driver in their life. It makes installation very awkward unless you have a new build house with a plasterboard ceiling with a dry lining box installed. As i have a lath and plaster ceiling installation was a pain. However, now that that minor nightmare is over they are very good.

    Love it but wish it came with an actual more detailed instruction manual. As the app is for both a thermostat and camera and the alarm it gets confusing on whether you have to switch things to home or away for just the alarm (I’m still yet to find out the answer to this one). Having recently had a house fire where two of my cats died these have put my mind at rest and I like that I can check it while away from home. If I’d got round to putting them up prior to the fire things could probably have turned out very differently as I was near to home when it happened

    This is a great, but really, really expensive smoke alarm.

    There is no way to square this circle, I could buy a smoke alarm for a fiver and it would wake me up if my house was on fire. Carbon Monoxide alarms are similarly inexpensive.

    This is internet connected… OK
    It links to my Nest thermostat apparently – I havent seen any evidence of that
    When its dark and you walk past it lights up – nice feature
    When it senses increasing smoke, it talks to you and lets you silence it – very nice.

    It’s cool, but very expensive.

    Very cool product. Easy to setup and the alerting is phenomenal. The only negative is the back-plate is crazy fragile, meaning you can easily drive the screw heads through the plate leaving you with a massive paper-weight. Nest provide spares but you have to wait an age to receive them.

    Whilst this mistake is user error, I would expect a 89 smoke alarm to be made of more sturdy stuff.

    Of the 3 I bought, 2 are installed and communicating with each other. So they work, well. I recommend them, just don’t be ham-fisted when screwing the plate into the ceiling.

    These Nest products were pricey however having had a fire in our previous house, the overall cost is minimal compared to what we went though. I am over the top now when leaving the house making double sure no plugs or dishwasher cycles are on (that’s what started the fire previously).

    What I like most with this product is the fact you’re notified in realtime should there be an alert. Considering we have two small dogs at home, the response time needs to be quick in the event of an emergency.

    Very simple to setup and sync with your wifi and phone app.

    Golden Review Award: 2 From Our UsersI would have given this product 5 stars but despite ordering a wired version I was sent a battery only version of the product. I have kept it as it allowed me to locate it in a slightly better position in my hallway. Easy to set up and link to my Nest account which allows me to monitor alongside my Nest thermostat (another excellent product and simple to use). I also really like the fact the Nest Protect product provides a night light when you pass under it in the dark.

    I was in the market for a new smoke alarm,and a Co2 alarm. After some deliberation the nest seemed the product for me. It performs both functions, is web connected (I love a gadget), has all the necessary safety approvals and has a night-light (useful with a small child in the house).
    The nest was very easy to setup and install. The supplied screws for the bracket were of very good quality and went into the plaster ceiling without any drama (no rawl plugs required). The nest app for Android and iOS works well and provides an overview of what the device is up to, and the ability to test it, without reaching up to press the button. This is probably the most expensive device of its type on the market, but it is a really nice piece of kit. I’ve had no alerts yet (thankfully), but that will be the true test of the product.

    Very easy setup via QR code on base of unit. Easy to fit in place of existing units. You can see the status of the units easily via the app or web, and also by the status ring light on the unit itself. Have three of these and a Nest Thermostat. They all work together which is great for energy saving notifying the thermostat that you are out. The units are very sensitive, but to the right alerts, ie normal cooking, no alert, but burning, yes, get alerts on phone as well as alarms. Very stylish products too! Very happy & confident of the level id protection offered.

    Carbon monoxide and smoke alarm yes, but much more than that as well. Motion sensitive night light, self check functions, spoken-word alarms and warnings as well as spoken guidance when setting up.

    Really amazing bit of kit. When used in conjunction with the Nest thermostat they can be used as sensors to detect if you’re in the house or not so the Thermostat can go into Auto-Away mode and turn off your heating.

    Any alarms etc can be found on your mobile phone and the Nest App gives you access to the information from all the Nest devices from anywhere in the world.

    Probably one of the best purchases we have made for a long time

    I had a Nest Thermostat already, so when I came to replace my old smoke detectors, Nest Protect was one of my top choices.

    Installation was easy, all I had to do was to replace the old 220V wire and base-plate with the ones from Nest. Scanned the QR code on the unit, waited for the App to add the unit to my account, and then installed the unit on the ceiling.

    Two days later, and so far there hasn’t be any false alarm yet. The Protect is also helping the Thermostat reducing the number of false auto-away’s. The night light is ultra cool.

    I might get a second one for a better coverage if the price drop a bit in the future.

    Well, where to begin… Is this a lot of money? sure, but is it worth it? that may depend on whether you have a love of gadgets or not! On the face of it this is an expensive smoke and CO detector, but to someone who owns more than one Nest product or someone who is looking for a “connected home” this is just what your after.

    It is well built and very simple to set up. I am an electrician and installed the 230V version with absolute ease, The instructions are very clear and concise and the Protect is set up before it goes up onto the ceiling.

    It is set up by downloading the Nest app which serves as the place you can deal with all you rNest products if you have more than one. From there you make an account and add the product by scanning the QR code on the back of it. You then run through some quick settings and your done!

    I like the pathway feature which can illuminate when you walk under it or can stay illuminated the whole time it is dark. I was hoping to have this replace leaving a light on, however its not bright enough for my liking, so a nice feature but for me it could have been brighter.

    If you have the Nest thermostat it also has a feature where if the Nest Protect detects CO the Thermostat will shut off the boiler. Again nice little touches.
    I also like the touch that you can connect it to Phillips Hue bulbs, so you could for example have them flash red upon an alert or come on at full brightness to light your path.

    Overall, yes its expensive but its well tied in to other Nest products and other things like Phillips Hue and it has a CO and smoke detector built in. I’d say its worth the money for the gadget loving homeowner.
