The Simplest and Most Affordable Way to Add Smarts to Your Smoke Alarm

The patented Roost Smart Battery uniquely combines a non-rechargeable lithium battery and advanced Wi-Fi in a familiar 9V package. Coupled with an intuitive smartphone app, the Roost Smart Battery solution delivers notifications to your smartphone when your smoke alarm activates, even if you are not at home. It also eliminates the annoying 3:00am chirping from your smoke alarms when the old battery is dying. In a typical smoke alarm, the Roost Smart Battery lasts more than 5 years, and even then you’ll receive a notification “before” the chirping ever begins.

With the same form factor as a conventional 9-volt battery, the Roost Smart Battery works with existing alarms to upgrade the safety and convenience of your home. Download the free Roost app and get alerts delivered to your smartphone if your alarm sounds, wherever you are. Invite friends and family to monitor your alarms for increased peace-of-mind.

This smart battery works with any 9V battery-enabled smoke or CO alarm and Wi-FI connection and no new alarms or expensive devices need to be purchased.
