    If carbon monoxide is present, Nest Protect links with your Nest Thermostat (sold separately) to automatically turn off your gas furnace.

      The wait for 2nd gen has paid off!

      I was always very interested in the original Nest Protect. I always loved the idea, but didn't feel the cost was justified given the negative reviews and early issues. Although they have been able to gradually improve the Nest Protect through software updates, I figured if I was patient enough, I could wait until they released a whole new hardware refresh. I'm glad I waited! Compared to the Nest Protect 1st gen, this one has an improved smoke chamber (fewer false alarms), smaller physical footprint, App Silence feature (silence alarm through app via Bluetooth), and other hardware improvements that extend the stated lifespan to ten years (up from seven)! All very good improvements. But does it work? Well, my house hasn't done the ultimate test of becoming engulfed in flames yet, but I did do some basic false alarm testing. Steam from a nearby bathroom, and light smoke from a candle, both failed to trip the alarm. So it seems their claims of fewer false alarms are true thus far. *Setup* Getting this set up was very easy. You can really tell they put a lot of work into the presentation and setup. The box is easy to open, and very welcoming with its simplistic and well-designed instructions. Everything in the manual is accompanied by very good pictures to help you along the way. Basically, the steps are: 1) Download app (Android and iOS compatible) and create a free account 2) Open Nest Protect box and remove hardware 3) With app ready to pair device, pull plastic tab from Nest Protect unit to power it on 4) Unit goes through some brief testing where you will be left with absolutely no doubt the alarm works (LOUD!) 5) Unit will pair with your phone so you can enter in wifi network info, after which it will connect to wifi 6) Remove old smoke detector and mounting plate 7) Disconnect old smoke detector wires and reconnect new wires included with Nest Protect 8) Screw in Newst Protect mounting plate and snap in other end of new wires to unit 9) Twist in unit to new mounting plate 10) Finish with another test and make final configuration changes via app. Done! This was the first time I had ever replaced a smoke detector, and I found it very easy. *Mobile App* The app is very well-designed and works well on both my phone and tablet. It also integrates with a ton of other home automation gadgets, which is really cool (Nest Thermostat obviously, Philips Hue bulbs, Skydrop sprinkler controller, and many others). Here's some of the things you can do from the app: - Change mode between Home and Away (not really relevant to CO detector, but good for other devices) - Iniitiate Nest Protect sound test, checkup - Silence alarm - Change Protect location (family room, bedroom, etc, for accurate communication) - Adjust Nest Sense: - - Toggle Pathlight to light your way when you are under Protect at night - - Nightly Promise (Unit self-tests and gives green "OK" light each night) - - Steam Check (reduce false alarms on steam, good for units near bathrooms) - - Heads Up (less loud & annoying pre-alarm warning when rising CO levels detected) - Adjust unit LED brightness (low, medium, high) - Change language (English, English (UK), Spanish, French, French (CA), Netherlands) - View unit status (model, serial, software version, battery status, replace date, last update time, wifi MAC/IP addresses) - Add/remove devices to your account - What To Do (advice on preparing for CO/fire alerts) - Device History (logs on alarms and updates) So overall, the Nest Protect is an expertly-designed device and I love it so far. It has everything I could expect from a smoke/CO detector. Although it would be awesome if it could double as a wireless access point or security camera! I will definitely update this as I get more time with my Nest Protect 2nd gen units, especially if I get false positives, or actual positives. But so far I am loving my Nest Protect.

      Great Product for Multi-Level Home

      I have seven Nest Protect Smoke/Carbon Monoxide units. Five of them are wired and two are battery operated. I also have the Nest Thermostat. Prior to purchasing them for my three level home, I had five wired/interconnected smoke detectors. When one would detect smoke at its location all the units would sound the alarm. I had no idea which unit was detecting the smoke and had to travel to each one on every level of the home to find the problem and reset the alarm. Now with the Nest Protect units if one of the units detects smoke you'll first hear a voice from each unit say for example "Heads-up, there's smoke in the Kitchen.The alarm my sound.", I'm able to go directly to the unit/area to see what the problem is and correct the issue. Additionally my SmartPhone receives a notification that smoke was detected in the kitchen. This has proved to be a terrific feature. These units come with a built in night light that come on when you approach them. When there's a fire, inhaling smoke can be just as dangerous as the fire itself. If you have a fan in your heating and cooling system and Nest Protect detects high levels of smoke, the Nest Thermostat can shut off fan-based systems to prevent smoke from circulating throughout your home. They also detect motion and can be used to determine if anyone is home. Nest Protect enhances the Auto-Away feature of a Nest Thermostat by improving Nest's knowledge of when you're home or away. In some homes, the thermostat may be installed in an area that makes it difficult to detect if you're away, such as an alcove or low-traffic hallway. Or, if you're working from your home office but your thermostat is in the living room, it may think you're gone for the day. If you have a wired Nest Protect, it will use its occupancy sensor to detect your presence and tell your thermostat so it won't turn down heating or cooling. Battery powered Nest Protects also help improve Auto-Away, but they'll update occupancy sensor readings less frequently than wired Nest Protects to conserve their battery charge. This is a great product, but it is expensive and that is my only negative comment.

      Returned: Missing One Critical Feature

      We purchased 5 Nest Protects to replace our old smoke detectors - which had reached the end of their 10-year usable life - because of three key features: integrated CO2 detection (to get rid of the separate, ugly plug-in detectors); the more subtle voice alerting with instructions (rather than the immediate and jarring shrieking that our old detectors would do if the kitchen got a little smoky); ability to control from the same app as our several Nest Thermostats. HOWEVER we had to return all the Nest Protects because they were missing one critical feature: compatibility with our home security system. This meant that the fire department would NOT be automatically alerted in case of fire. This would not be a major issue if we were at home in the unlikely event of fire, as we could call the fire department from our cell phones on the way out of the house. But if we were out of the house or away on vacation, the fire department would only learn of fire AFTER a neighbor or passerby took notice and called it in... and by the time fire was that noticeable, how far would the fire have progressed? How much of the house would already be destroyed? Most importantly, what chances would our pets have of being saved? While such an event is unlikely, it was not a risk we were willing to take, But we really wanted to keep the Nest Protects, so looked for security systems compatible with them, willing to replace the one that had been installed by the previous owners of our home, in order to use th Nest Protects. So I searched the 'works with nest' section of their web site and found that Nest Protect is not compatible with ANY home security systems with central monitoring (ADT Pulse appears to be compatible with Nest thermostats, but require using public their own proprietary smoke/CO2 detectors). The only compatible security systems were a couple of startups (one still in Kickstarter stage) that had Wi-Fi enabled DIY systems that worked like a Sonos audio system, allowing owners to install detectors, cameras, etc. where they please. But I was not willing to trust my family's safety and all our belongings to a company that could be gone by the time I press 'publish' on this review. Bottom line: Nest Connect is a very cool product, probably good for people in apartments where building alarms or neighbors would quickly notice smoke or fire if no one were home. We ended up buying traditional smoke detectors with integrated CO2 (so we can still get rid of the plug-in units). We look forward to considering Nest again, when the 10-year life on our new detectors is past. Hope by then Nest can integrate with central alarm monitoring services.

      Wonderful addition to my home

      I carry both the Nest Learning Thermostat (3 years) and the Nest Cam (1 year) in my home so it was not a surprise to pull the trigger on the Nest Protect. Due to the fact that my current fire detectors are wired, I was unsure how to start adding the Nest Protect into the mix. For me, it was decided to replace my current fire detector near the Master Bedroom with the Nest Protect and see how well its integrates into the existing wiring. I also wanted to take advantage of features such as "auto" illuminate when walking by when the lights are off, and the function for Carbon detection closest to the bedroom. The installation was very easy and the instructions made it clear which wires to use and which ones to cap. After installing I ran through a complete Nest Protect test and wow is the alarm loud! The voice is also loud and clear enough to hear for any alerts. After installing, the Nest Protect did not break the connection chain my other alarms still had with each other. My favorite feature, besides life saving alarms and warnings, is the illumination at night. Getting up to grab a drink of water or check on something in the home enables the Nest Protect illumination function to light up my path. It senses my approach, turns on, and fades out as I leave the motion sensor area. It is a great feature outside of its real function (fire/carbon detection). Overall I would highly recommend the Nest Protect and plan to replace my remaining fire alarm devices with this device.

      Added technology and added safety

      There are many options out there for fire alarms that cost far less. However, I found it worth it to invest in the Nest Protect. I do own other best products and this integrates with those. So I can see what Nest protect is in which room all on the same app. What I personally like is the ability to know exactly where smoke would be coming from. If I were to be on the fourth floor in the middle of the night, it would say “there is smoke in the living room” which would help me in quickly thinking of how to get out of the house and what area it’s going from. I have two small children so this would be helpful. The other day someone was cooking in the kitchen and didn’t place the fan on. The smoke began to accumulate out into the hallway as a result. I happened to be working but saw the alert in my phone starting that smoke was accumulating but not necessarily that there was fire. It also alerted me that smoke was clearing shortly after (bc they opened a door and let out the smoke). I also happened to have a nest camera in that area of the home which made it easy for me to open my phone, turn to the camera on that floor and in that room and know that here wasn’t a blazing fire. I then called home to make sure that all was ok regardless. There is also a little added bonus of a night light that comes w it. At first it’s very faint but you can adjust the brightness. I can go downstairs in the middle of the night for a glass of water and not really have to turn on the lights because the alarms start softly illuminating the walk way.

      Great Peace of Mind Smoke and CO Detector

      First let me start by saying the Nest Protect Smoke and CO is little pricey for the physical unit but the peace of mind that comes with having reliable safety equipment in your home is priceless. I purchased 9 of the wired versions and was super excited when I installed them; 25 mins and they were all on the ceiling. The voice alerts, the warning before the alarm sounds, the location of the hazard in your home etc. makes these units way better than the standard smoke alarms. We bought these smoke/co alerts as our 11 year old units have run their course. The units started screaming at 11:30pm for no reason at all. Trying to quite them was a nightmare because I didn't know what was going on and which unit was triggered. After quieting them all, cleaning around the units for dust; they started screaming again around 4:30am. Time to trash them and get new ones. Since we have the Nest thermostats, this was an easy choice. The smoke/co alerts are now monitored from the Nest app, no more chirping low battery indicators, no more wondering if they are really working and so on. These new generation 2 units have a night light, status indicators and an overall cool design. Now that the newness has worn off, they just blend in to the home with nothing else to get excited about. They just sit and wait. But - as long as I know they are there, my family can sleep easy. You really can get cheaper units to do the exact same job and save some money or you can opt for the new technology and have a smarter home.

      A very good item

      This is the first of a few I will be buying to replace the remaining of my single smoke alarms. I feel much safer knowing I have a multi purpose device that keeps me up to date on its status. I really like the light that is built in and comes on when it senses motion: it was very easy to install and set up. It has a very nice stream line look and it doesn't even look like a life safety device. I recommend that those who have not looked into this device take the time to read about it and it's reviews. I bought this for the safely of my family. It's really amazing to feel a high level of comfort, knowing we are protected when we are home and I know what is going on in our home while we are away. With so many deaths caused by carbon monoxide and smoke, why would you even think twice about installing a device that actually keeps you up to date on its status. Funny that having typical smoke alarms I would not replace the batteries every year, with my new smoke alarm this will be something you will never forget. Even though you are paying a bit more for this smoke/ carbon monoxide alarm device, I realize that it's a investment for the protection of your family and your property. One of the things that convinced me of making this purchase was the all the information it provides you on its own, being connected to your wifi. It tests itself daily and I can. Always check my app and feel assured that it's up to date, it will automatically update itself as they make changes to its software. I feel that with this state of the art life safety device, once everyone knows about its ability it will become a typical house hold item. Based on this purchase I have.l decided to make sure, that the safety of my family, becomes a priority in my life. Once it's installed and it is operating, it becomes part of your home and part of your family. It talks to you and keeps you informed of its condition. You will notice that you get a better nights rest knowing its protecting you.

      Expensive, but worthit

      My family and I bought a house a bit over a year ago, and I immediately bought a Nest thermostat and loved it. I had considered upgrading to the Nest Protects too, but couldn't justify the $120 per price tag. On Black Friday however, the price came down to $100 and I decided to get one to try. I now have them throughout the house. There are a few things that I think make these great and make them worth the extra money. In no particular order: - It's nice that these connect to one another without needing to wire them. In my house, the basement wasn't connected to the rest of the house before, but now they are. It would have been almost impossible to run a wire to connect these, so just having it happen is great. - It's nice that it tells you when the power goes off. This was something that I didn't even think about it doing, and it's nice to know if you lose power when you're out. - At night, if it senses movement, it will turn on a really dim light. This light is dim enough for me to vaguely see the walls, but not bright enough to wake up people. When I would sneak upstairs after the kids went to bed, I used to use my phone as a flashlight and worry I might wake someone. Now I don't need to. These features, only one of which have anything to do with the main regular function of the devices, work so well for me that I am more than happy with paying the additional cost for these detectors over the standard ones that I had. If you're on the fence, take the plunge on one and check it out. You may be as pleasantly surprised as I was!
