What should I do if I can manually turn on the light, but it doesn't automatically turn on through motion sensing? (ELEGRP Smart Sensor Switch: SSS10, SSS30)

If the ring indicator light is blue, it means that the current smart sensor switch is set to manual mode. You can change the schedule to automatic mode. If the ring indicator light is white, please check the ambient light level and sensitivity settings. The smart sensor switch will only automatically turn on the light when it meets the set levels of ambient light and motion sensor sensitivity.
