Could you help to confirm that could you control with the button from Yeelight application “Turn All On” and “Turn All Off” to see if the offline devices in your application have response?
I have the exact same problem and it seems to have intensified over the past couple of weeks. I have 2 bulbs, 2 lightstrips and a desk lamp. They stop connecting to wifi randomly. I’ve been experiencing the problem from the beginning, but they would only lose connection every couple of weeks. Now it’s almost on a daily basis. I have to disconnect them from the plug and once I plug them in again they regain connection (no need to reset them). Or wait a couple of hours and they randomly reconnect. Really annoying!
My new bulb also disconnects from wifi after maybe 15 minutes of use. After that I have to unplug it from power source and wait for about 30 minutes than to reset it and connect again. But 15 minutes later it stops to work again.
I am on the US server, most up to date app and firmware. Also my router is less than 2 meters from the bulb.
I don’t know if it is defective or it can be fixed with future updates.
Hello, I have the same problem here. Just got my Yeelight Mijia Desk Lamp. It goes “offline” after a time 2-30 minutes. I can still switch it on and off(all on all off), but nothing else. Mi Home App also tells me Miija Desk Lamp is offline.
Wifi is close and stable. Tried Singapore and US server.
After resetting and reconnecting it works for another 5 minutes…
What can I do? At the moment it pretty much useless…
