Hello all,
I have this recurrent issue for years… I wonder if I’m the only one or if someone has found a fix.
The issue:
My Yeelight LED bulbs 1S (YLDP13YL) all stop responding from LAN Control after about ~1200h uptime.
A bit less actually, but I never managed to pinpoint the exact time. I would say between 1100h and 1200h, but every time I see it, it is close to 1200h.
I tried to force wifi disconnection, disabling then enabling again LAN control on the bulbs, no luck.
The only “fix” is to power cycle the bulb.
It happens with all of them.
I’m running FW 2.1.7_0039.
Note: when it happens, it is still working more or less from Yeelight or Mi Home app, but it is slow and after a while, I lose control too from the app.
My guess is there is a memory leak or something not behaving properly after ~1200 hours.
I searched online but couldn’t find any similar issue.
If you have any clue or idea, I’ll be happy to read you 
Thanks
