I installed one of the HS220 dimmer switches with my new canless recessed lights and it worked great for several months.
A few days ago I noticed the lights flicker and then shortly after they shut off completely. The smart switch showed it was turned on in the app and physically looking at the device. I shut off the switch and the after waiting a little while I turned the switch back on and it worked fine for a few minutes and turned off again.
Here are the lights I am using.
6 Inch Recessed Lighting 3000K Warm White Light Slim Led Downlight Dimmable with Junction Box 12.5W 850lm IC Rated Bbounder Ultra-Thin Canless Recessed Lights ETL and Energy Star Certified 6 Pack https://www.amazon.com/dp/B07NP7SCZM/ref=cm_sw_r_cp_api_i_L1xlFb3WP8XM2
I am wondering if the HS220 switch is not compatable with the lights I have?
