You’ll know, from anywhere

Nest Protect alerts your phone¹ when something’s wrong at home. Just burned the toast? When there’s only a little smoke, you can hush it with the Nest app on your phone or tablet.

It’s thoughtful, not annoying

Nest Protect tests itself over 400 times a day — just check the status in the Nest app. It also has a friendly human voice that gives you early warnings.

It tells you what and where the danger is

The new Split-Spectrum Sensor looks for both fast and slow-burning fires. It also has a 10-year CO sensor so it can tell you where poisonous, invisible CO is hiding.

More than one color. To tell you more than one thing.

The Nest Protect light ring can display different colors depending on what’s going on.

Works with your Nest Thermostat and Nest Cam

If Nest Protect sounds the alarm, it tells your Nest Thermostat to turn off the furnace. Your Nest Cam will also record a clip so you can see what happened.
