Nest Protect Smoke and Carbon Monoxide Alarm — 2nd Generation (Battery): Nest Protect reliably detects and alerts you to the presence of smoke or carbon monoxide in your home. The alarm speaks to you in a calm, clear, human voice, telling you the location of the danger. It also provides smartphone alerts and battery status updates to help protect your home while you're away.
Protect your loved ones and your home
Detects levels of smoke and carbon monoxide within the home and tests itself automatically.
Receive clear direction in an emergency
Alarm speaks to you with a human voice and tells you the location and levels of smoke or carbon monoxide when they are present.
Send alerts to your smartphone
Provides battery and sensor status notifications so you're always informed, and safety history so you can see what happened over the last 10 days. You can even silence the alarm from your smartphone.
Get an early warning signal
If a cooking mishap leads to a small amount of smoke, Nest Protect will let you know without setting off the full alarm.
Stay on top of any situation
Synchronized sensors ensure that when 1 alarm senses danger, every alarm in the house will make you aware of the situation.
If carbon monoxide is present, Nest Protect links with your Nest Thermostat (sold separately) to automatically turn off your gas furnace.
Light your path at night
Pathlight illuminates your way in the dark. Adjust its brightness, leave it on as a nightlight or turn it off from the Nest Protect app.
Nest Protect is one of the most comprehensive, of the smart smoke detectors I've ever purchased. Not only does it pick up several types of fires, as well as carbon monoxide, but it also does the best job at alerting you of the danger. It also works with a wide range of smart-home products. I've set my Philips Hue lights to turn on automatically when the Nest Protect goes off. Pretty cool!
Are you kidding me?! Replaced the batteries but still bad sensor. Dusted it as recommended (although not dusty) and still beeps saying I need to replace it. Why would I get another one when this one took a crap so soon. And back cover over batteries will not stay closed. No earthquakes where I live so not sure why covet won’t close or why it stopped. Made in China most likely reason. And now not returnable—of course.
These detectors are awesome, in some rooms I have them set up in another language and others in English. Love the night light feature! Great and easy to install, find location and follow instructions on the app

Preeminent Protection for Your Loved Ones
Alarm, Set up
Nest Protect Smart Smoke/Carbon Monoxide Alarm provides the ultimate protection & peace of mind. The intelligent alerts discriminate between steam and smoke. A clear "Heads Up!" pre-alert gently cautions you in situations when close proximity to steam or a little smoke in the kitchen, for example, is about to trigger an alert. You can silence a false alarm using your phone. Multiple units share alerts to all rooms & to your NEST App on your phone, tablet & computer - so you are protected throughout your home!
The "Promise" is a ring of green light that illuminates nightly to let you know everything is good. Walk under NEST at night & the ring glows white, forming a pathlight. During Heads Up, it glows yellow. During an emergency, it glows red.
NEST Protect self-tests, alerting you first by the phone app that it will sound. Everything is tested: sensors / voice / siren. Tests are dated & are sent to your app. A monthly summary even shows the exact date & time of each test.
This is the premiere smoke detector, able to detect CO2 (even produces a completely different sound, for instant identification). NEST Protect senses both fast and slow burning fires.
NO CHIRPS!! This advanced Smoke Alarm eliminates all of the hassles of pesky chirps from low batteries, with super long lasting Lithium Batteries included that last years. Battery alerts are through your App & by voice on the Alarm.
To set-up, simply scan the QR Code on the back of the NEST & follow the voice instructions. Easiest set-up ever!
NEST Protect earns my highest recommendation - no other Smoke / CO2 Alarm even comes close!

The wait for gen 2 has paid off!
App, Set up
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.
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.
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.
This is my 5th Nest Protect (located in my home office) and it saved my house from a potential catastrophe. I left the gas burner on while sterilizing baby bottles and went to work. The water boiled out and the alarm activated saying there was smoke in the hallway. Since no one was home, I was receiving alerts on my phone initially from the detector in the hallway; that is until all smoke detectors ultimately started alerting me. I immediately sent a relative to the home to find the gas burner on with all bottles melted. The situation could have become worse if I wasn't notified via alerts on my phone. Since I setup the alarm to notify other relatives, they were calling me as well to see if I was ok. Thank you Nest Protect!
My existing smoke alarms were well over the "good" date by 10 years when I checked! I knew it was time then to get some replacement detectors as well as an additional unit to cover my basement, where my utilities are, but with no existing protection.
Made sence then, to go all in and get a good full spectrum smoke & CO detector for all 3 areas. Also, having them tied into my home network for remote access, was icing on the cake.
I bought the 3- pack as it was the right number of detectors AND BestBuy price matched! Can't go wrong!!
They were VERY easy to physically install. I was initially skeptical of the included hardware, but it worked perfectly. I was replacing some old First Alert models and the mounting holes don't match up unfortunately. But, it wasn't an issue. You don't need any special tools either; Just a screwdriver. They blend in nicely with the white ceiling which was a pleasant discovery.
The app install on my Android based LG G5 went without a hitch and I had all 3 detectors connected in no time.
All together, I had all 3 items physically & virtually installed in less than 45 min; from unwrapping the 3pack to walking away. I didn't even have to install batteries, as they came with & installed in each unit. The units self test (or you can have them test themselves via the app) on a schedule and you can view or hear the results. If batteries get low, they literally say that, so you know which one needs batteries.
They aren't cheap, but as my & my families lives might literally depend on them, it was a very good investment. These items again, are dual spectrum for smoke AND they also are CO detectors. I really like that they're networked and that they talk when in action. Another handy feature is that at night, they also act as a night light for a few moments when you walk under them. Just for a few seconds, but enough to be helpful.
Overall, I'm very pleased with the purchase and whole heartedly recommend them. Check the dates on your current units - did you know they're only practically good for 10 years?? If it's time to replace them, buy these NEST units. If you don't have any in your home, then buy these TODAY! Money well spent, because what is your (or family's) life worth???
When you buy quality, you only cry once.
A:Answer No, however, you will not get notifications via smartphone if it's not connected the the Nest app. The purpose for a "smart" fire/CO device is to alert you when not at home via the app. In addition, it has other feature like automatically checking the devices batteries and sensors. The device will always alert you locally with an audible alarm for fire or CO, even without WiFi/internet.

Here is the Nest Protect setup guide: https://nest.com/support/article/How-do-I-connect-my-Nest-Protect-Wi-fi-and-my-Nest-Account
A:Answer Yes, you can schedule a time/day for the self check in the app and you can set it up to remind you that it's supposed to happen, and even cancel it. The self check seems to be the alert tone and the voice, but I haven't been home for it yet. All of the devices self check at once.
A:Answer Yes, interconnect works on battery version and does not require WiFi once it is setup. From the Nest website:
"Once it is set up, Wireless Interconnect will work even without Wi-Fi in your home, since it operates on a different wireless protocol to connect all of your Nest Protects.
Nest Protect Wired (120V or 230V) and Nest Protect (Battery) are compatible and can interconnect with each other."
