Installed HS200 smart switch on November 22, 2022 and has worked without issue until today where now the lights are "stuck" on.

The app on/off is not working and the the manual switch is not working either. The only way I can turn the lights on/off is using the room circuit breaker.

I have 3 other switches installed on the same date noted above and they are functioning correctly.

The switch in  question has two 12W (60W equivalent) lights connected to it.

I have updated the firmware, reset router and reset/reinstalled the switch using TP Link yet it still is not working.

I can hear the switch "click" when turning on/off with the app but the lights remain on. Toggling the switch on/off manually does nothing.

From what I have read the switch relay has failed and requires replacement.

Please send me a replacement for this faulty switch ASAP.
