Hello! I’ve just installed a HS220 Smart Dimmer from TP-Link, however, after turning on my breaker the switch doesn’t seem to turn on to start the setup. I have a wire that’s daisy chained between the 2 existing switches I have in my 2-gang box. I assumed that it was the line wire but I could be wrong.
For some reason the switch doesn’t start the setup, I have a HS200 in another room which is slightly easier to install and it works fine. Any tips on how to debug this?
