SmartWise Smoke sensor is a smoke detector compatible with the Sonoff smart home product family. It connects wirelessly via Sonoff and SmartWise RF gateway to the eWeLink app that controls Sonoff and SmartWise devices (smart light switch, smart switch relay and smart plugs). Not only does it provide a local light and sound alarm for detected smoke, but it can also send an alarm to a mobile phone via Sonoff RF Bridge and SmartWise RF Bridge.
