Hi Xhangxin,
No since 1/31 I have not had further issues, but before it also worked for several months where all devices were showing without any problems. Have you done any changes or found the cause of the problem in the logs?
All devices are showing up in Yeelight App but only 7 devices from yeelight APP is showing up in MI HOME?
I Have described the issues with MI HOME in this thread:
