I am owner of Bedside lamp and at the beginning it worked quite wall. I was able to pair it with application. However I changed phone (LG G3 to Xiaomi Mi A1) and now I can’t connect to lamp and even I can’t restart. I hold power button and inserting power cord however nothing happen :(.
Any ideas how to fix this?
Do you mean you can’t power on the lamp?
No, no. I can power up the lamp, however when I perform “restart combination” it is not restarted. For example before restart I set red color with touch controls, after performing “restart combination” lamps still glows red. Like restart not working 
if you have the mijia (golden base) you reset it by holding both power and mode buttons at the same time for a few seconds. It will turn on while you are pressing them, change state a couple of times, then stay fixed with a white light. At this point reset is done
