Meet Nest Protect.

The Nest Protect smoke and carbon monoxide (CO) alarm sends a message to your phone if the alarm goes off or the batteries run low, so you can know even if you’re not home. And instead of just chirping and howling at you, Nest Protect speaks with a human voice. It gives you a friendly Heads-Up before burning toast turns into an emergency, and tells you the room where the smoke or CO is located. Low-battery chirps ever rattle your dreams?
Nightly Promise shows you its sensors and batteries are working before you doze off.
