Smart connected devices can help you keep an eye on things at home and automate things easier. You don’t always need to replace your existing gadgets to make your home smarter though. Take the Roost Smart Battery for instance. This is a neat battery that turns your existing smoke or carbon monoxide detector into a smart device. All you need is to download the companion app, connect to WiFi, and insert your Roost into your smoke detector.
Thanks to Roost and its companion app, you get alerts when one of your smoke alarms activate. You can view all your smoke alarms, find out when the battery is running low, and even add your emergency contacts. Roost will cost as low as $25. It will be compatible with iOS and Android devices.[where to get it]
