Retrofit Smoke Detectors

This smart battery indicates how you can transform your existing house into one integrating The Internet of Things. From startup Roost, the smart battery for smoke alarms is currently looking for investors via crowdfunding platform Kickstarter. Your old smoke alarm and current smartphone can be used alongside Roost's WiFi-connected product to "retrofit your way into an intelligent, connected home" while also offering peace of mind at the same time.

This invention turns your existing smoke detector into a smart one with the help of a companion app. In the event you are out, the app will notify you if the alarm goes off and provides you one-touch access to emergency numbers. It even avoids the annoying chirping sound by warning you weeks in advance.
