Milesight - WS558
Smart Light Controller

The Milesight WS558 Smart Light Controller is a central control system that manages up to 8 lighting circuits to improve the efficiency of power consumption. Streamline deployment options with the LN Type or Switch Type versions to meet specific wiring and maximum electricity flow requirements. The WS588 is ideal for schools, offices, hospitals and shopping centres and for the wireless control of indoor lights, fans and heaters.

Prevent short circuit and overload of the WS558 and the connected lights with overcurrent protection. Eliminate reconfiguring the smart light controller upon power failure with the Power-Off Memory Function. Save and recall present settings to resume operation once power has been restored. Flexible power consumption measurement from the LN Type saves energy and lowers electric bills.

Remote control timers from a smartphone by setting on / off schedules for automatic light function. Featuring LoRaWAN technology, the controller encrypts and transmits power and switch status data. The Milesight D2D (Device to Device) protocol using LoRaWAN enables direct communication without using a LoRaWAN gateway.


  • Data collection for current, voltage and electrical consumption
  • Schedule remote timing to turn on/off devices
  • Configurable remotely via webpage or mobile
  • Equipped with NFC for easy configuration
  • Compliant with standard LoRaWAN gateways and network servers
