28. What should I do when I can’t turn the wall switch on/off manually?

A: Please check the LEDs. If all the LEDs are off:
    • Make sure that you restore power to the wall switch at the circuit breaker.
    • Make sure the wall switch is wired correctly.
    • Make sure your master switch has been installed in electrical box with both live and neutral wire. If you are not sure,

    switch installation position of your master and add-on switch and try again.
