The Best Smart Smoke Alarm

Smoke alarms will warn you of danger, but not if you aren’t home to hear them. (They’re also ugly and a pain to shush, and they shriek at burnt toast.) Smart smoke alarms are the cure, and Google Nest Protect is the only one worth buying. It sends speedy alerts of smoke or carbon monoxide to your phone, has great design, is simple to mute, and has a “heads-up” warning before triggering its siren. The Protect also self-tests and has a motion-activated path light.
