I installed 2 HS220 dimmers. 1st one works flawlessly in kitchen. Able to control kitchen switch with voice, app and the physical switch, no issues at all.
The 2nd one in bedroom has issues. It works only on Kasa app, Google home app and google assistant voice control. Does not turn on or off on the wall switch. The dimmer buttons on wall switch works once the lights are switched on using app/voice. Is this an issue with switch or wiring?
