I have a Sonoff POW. It was running fine and now when I switch it on with the native button or the app the red LED and the green LED are steady. I can hear and feel it switch when I activate it. The fuse checks good. I tried reset and setup again and the same issue. Red LED won't turn off and the switch has no power output.

Harry, have you solved this, yet? Sitting here with the same problem.
