After I update the firmware from 1.4.8_168 to 1.4.8_173.
I have encountered the same problem. When I ‘on’ the ceiling light. If I press ‘off’ and then try to press ‘on’ again, it’s won’t light up, need to wait for 5-10 mins in ‘off’ position, before I can manage to turn ‘on’ the ceiling light,
Can you help? I’am unable to reset the light in this case.
