Pinpoint the problem

Nest Protect doesn't just detect the problem, but tells you where it is so you can fix it.

Get notifications

Nest Protect pushes alerts to your phone if it detects a problem, even when you're not at home.

Rest easy at night

Nightly Promise: a green glow when you turn the lights out to let you know it's working.

CO detection

Nest Protect isn't just a smoke alarm; it also detects carbon monoxide, which is invisible.





Thinks, speaks, and alerts your phone.

Is it just a bagel burning in the toaster, or is there a more serious issue? With a friendly human voice, Nest Protect can warn you about a problem before it becomes a bigger problem. It can push alarms to your phone, and once you've located the issue, you can even silence it from your phone. Nest Protect tells you over the app when its battery is low - no more annoying chirps. In addition to using the app to test or hush the alarm, it can even perform its own safety checks automatically and give you a full report.
