My ES20M has been functional for almost a year now. No issues, until last night.

The light was on while I was putting my son to sleep. At 10:30, the switch turned off by itself while we were in the room. When I tried to turn the switch back on, it would not turn on. I plugged the light into the bottom socket that is not controlled by the switch and it came on, so I know the light is functional. When I checked on the app, I noticed it had also lost connection to wifi. I tried to hold the reset button, but nothing happened. I think the switch broke, how do I apply for a warranty replacement?

Thanks
