    Worry-Free Deployment

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


    Power Consumption Measurement

    Tips to Save Energy

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



    Overcurrent Protection

    Real-Time Alarm via Milesight IoT Cloud

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

    Power-Off Memory Function

    Never Bother to Reconfigure Again
    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.

    Milesight IoT Cloud

    • Compatible with Milesight IoT Cloud to monitor and control the device status at your fingertips.
    • Comprehensive reports on voltage, current, power, and cumulative power consumption for a more accurate measurement of energy consumption.
