Multiple Scenes Based on Milesight D2D Communication
Move to a More Hands-Free Office Life
Milesight D2D protocol featuring LoRa enables the communication among different Milesight LoRaWAN® node devices without a LoRaWAN® gateway.
Easy to Test the Light Status
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.
