How to Get It
Product Overview
The battery Google Nest Protect smoke and CO alarm looks for fast-burning fires, smoldering fires, and carbon monoxide. It tells you where the danger is and alerts your phone in case you're not home.1
- Heads up, there's smoke in the kitchen. The Nest Protect smoke and CO alarm speaks up in a friendly voice to give you an early warning when there's smoke or carbon monoxide in your home.
- Every second counts. The Split-Spectrum Sensor uses two wavelengths of light to look for both fast-burning and smoldering fires. Plus, the CO detector looks out for carbon monoxide and tells you where it's located.
- Tells you where the danger is. When one Nest Protect speaks, so do all the others in your home. The alarm in your kitchen can tell you if there's smoke upstairs.
- Simple setup. Easily set up your smoke and CO alarm in just minutes using the Nest app.
- Alerts on your phone. Know when something's wrong, even when you're away from home. With family accounts, everyone in your household can sign up for alerts.1
- Hush alarms with your phone, not your dish towel. If everything's under control and there's only a little smoke, App Silence lets you quiet the alarm from your phone.
- Count sheep, not chirps. No more low-battery chirps at 2 AM. Nest Protect tests its own batteries and gives you a Nightly Promise when you turn off the lights - the green glow lets you know everything is working.
- Lights your way in the dark. If you need a glass of milk in the middle of the night, Pathlight lights your way.
- Get peace of mind with Safety Check.Use Safety Check to test all your smoke and CO alarms with just a tap, and get a full report once the test is done.
- 10-year lifespan. Nest Protect has sensors with a 10-year lifespan to keep your family safe for up to a decade. Plus, it comes in wired and battery models, so you can choose the setup that works best for you.

Traditional is OUT!
Amazing!!! 2 in 1 it’s great not to have 2 different detectors in your home.

Lived only 3 years!
After 3 years it started beeping at me like an old smoke detector from 1980. There is a sensor error message but no option to muted from the app! I tried to clean it with a pressurized air spray with no success. I have 12 nest detectors and I will replace them all!

The best smoke and carbon monoxide sensor on the market. Expensive, but worth the price - my previous units went off after a power failure and could not be silenced. The ability to silence these units from my phone is a big plus. Also love that it alerts my phone anytime an alarm is triggered even if I am away. Very easy to install - I would imagine that the average Home Depot shopper would have the skills. There are a lot of on line videos that detail the process. I would unreservedly recommend these to anyone in need of new smoke detectors.

BUYER BEWARE!!!
I can't review this product as I didn't even install it. I'm not spending this kind of money only to get a unit that has almost half its life depleted. I can't really blame Home Depot for this as the expiration date isn't stated on the packaging. I will be returning it in the morning.

The entire Nest suite is fantastic. The Nest Protect is effective detecting even low levels of smoke. The Nest app shows you daily test results. Highly recommended.

love the smart integrations
love the smart integrations that will turn off the heating system if smoke or co is detected. It actually kicked in once when I was messing around with my boilers venting system and tuning (Don't worry I'm a pro). It'd be nice if they made one for outdoor conditions. I'd like to monitor my attic and garage.

I love the Nest/Google sensors! This is my seventh one that I put into my home. Very easy to install if you already have a wired one (as this is what this new one is to replace), you will only need to hook up the black and white wires the red one is just capped, and please be sure you have the power off of course. Software so easy to install and use. It actually speaks to you if it sounds the alarm and tells you where and is wrong. The nightlight feature is great-turns on when it senses motion.
