I have the KS230 v2 installed. I have 4 recessed cans with 65 watt LEDs. I noticed randomly the lights start to flicker. 
I did some digging online and there were some suggestions. 
1) LEDs lights- try different light

2) bad switch -swap switch 

3) issue with wiring.- loose nuetral.-check connections 

im in the process of narrowing it down but does anyone have any suggestions?

fyi, the electrical wiring is brand new to both switches and the cans. 
thank you
