I am trying to replace the switch that controls KODA LED cieling light. 
I am not trained technician, so please bear layman language. I am assuming the following in my setup:
   White wire: neutral
   Black wires: live & load
   Copper wire: ground

The current setup:
   1. One of the screws on the switch has a white & black wire
    2. The other screw has a black wire
    3. In the box I can see a wire-nut with copper & white wire 

I tried a conventional setup ie white with white, green with copper. The LED on the switch lights up also the WiFi goes orange/green however the actual light bulb does not work. I interchanged the load & live wires, that did not help either. Both cases the light does not work.

Please advise on the correct wiring. Have I damaged the switch itself?
