The Milesight WS502 replaces conventional wall switches and adds intelligent control and monitoring capabilities. Using LoRaWAN EU868, lighting and electrical appliances can be switched remotely, automated, and centrally managed.
Beyond simple ON/OFF control, the WS502 provides built-in energy measurement, including voltage, current, power factor, active power, and energy consumption (kWh). This makes it suitable for both load control and energy optimization projects.
Typical applications include:
Office buildings
Hospitality and hotels
Retail chains
Industrial facilities
Public buildings
Time-based switching allows automated lighting schedules. Features such as delay switch, switch lock, and overcurrent protection enhance operational safety and flexibility.
With Milesight D2D communication, compatible devices can communicate directly without a LoRaWAN gateway, reducing latency and infrastructure costs in local automation scenarios.
Configuration is performed via NFC using a mobile app or via downlink. The WS502 is designed for professional wall-mounted installations in commercial and smart building environments.
