Roost Smart Smoke Alarm for Smart Homes

In the past few months, we have seen a bunch of interesting smart smoke alarms. The Roost Smart Smoke Alarm is another tool that helps you stay out of trouble at home. It connects to your wireless network and detects slow moldering and flaming fires. You get a notification on your phone when something is wrong.

The companion app helps you keep up. It lets you set up monitors and let your friends monitor alarms. The app also lets you know the last time each alarm was sounded. The most expensive version will be available for under $80.
