Arrive and every light is blazing? Half-way home you remember the fans are still spinning? Wire this cabinet-mounted controller and with one phone tap shut down eight circuits at once. Local buttons let you test each line without the network; timed schedules keep unused loads off after hours. A built-in metering chip watches voltage, current and power, flagging jumps before breakers trip. Add a new circuit in seconds—just tap your phone via NFC and the Type-C port; no screwdriver or rewiring required. Wall bracket or DIN rail, office, mall or school retro-fit—done without chasing walls or chasing people.

Ideal for smart buildings, smart offices, smart campuses, smart factories, large shopping malls, and smart homes.

Milesight D2D protocol featuring LoRa enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.

WS558 supports local switch button control and allows to test the light status without networking after powering up the device.

The power consumption measurement and flexible schedule settings would help to save power and lower electric bills. (Only LN Type)

The overcurrent protection prevents the connected lights and the smart controller itself from damage of short circuit and overload.

In case of any power failure, the present settings will be saved and WS558 will resume to previous operating status after power has been restored.
