WS502 is a smart LoRaWAN® wall switch for the local and remote control of lights and electrical appliances. It adopts two standard sizes for most of international wall switch types, which can replace the traditional wall switches directly. Compliant with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution,WS502 can be monitored and controlled via web page or mobile App remotely and triggered by other Milesight sensors. WS502 can be widely used for indoor applications in homes, offices, hotels, museums, etc.
