Milesight WS501-915M Smart LoRaWAN Wall Switch
Transform traditional lighting control into an intelligent automated system with the outstanding Milesight WS501-915M.
This premier smart wall switch directly replaces conventional wall switches to provide seamless local and remote control of lights and electrical appliances. Operating on the 915 MHz frequency band (US915/AU915), the WS501-915M combines tactile button responsiveness with advanced energy measurement capabilities to deliver comprehensive power monitoring across indoor environments. Built with high-reliability relays and anti-flaming polycarbonate material, it ensures safe, long-term operation.
Seamlessly integrating with Milesight LoRaWAN® gateways and leading LoRaWAN® network servers, the WS501-915M operates in Class C mode for continuous, real-time responsiveness. When paired with the Milesight IoT Cloud platform, it enables remote web and mobile control, scheduled automation, and scene synchronization triggered by other IoT sensors.
The Milesight D2D (Device-to-Device) capability offers ultra-low latency control directly between switches and sensors without requiring a gateway, while the built-in power measurement feature collects precise voltage, current, active power, and total energy consumption data in real time.
Ideal for diverse indoor applications such as smart offices, commercial facilities, hospitality, and residential properties, the WS501-915M is your go-to solution for reliable lighting automation and energy management.
