@ezcGman, previously this question was discussed in this thread 吸顶灯总是掉线 and today I also mentioned same problem here: Why is there no support? and got an answer. Do not know what will be in the result, but who knows.
Currently I managed it through HA. I installed smart switches. And my HA monitors status of the Yeelight lights. In case they do not appear online in 5 minutes it just physically do power off/ power on. And connection restored in most cases. If not - repeat 
but ofcource it is not a best way to do it.
