I bet 99.99% is the WiFi connection lost issue that your very capable staff have been DONE ALL THE SELF-TESTING BUT FOUND NO PROBLEM AT ALL except literary every customer here complaining about the same thing, !!!CONNECTION LOST!!! Since…2 years ago?
BTW just now, my ceiling light YLXD01YL has lost its connection again just like usual. WiFi Signal Strength is 21%, RSSI -73, Packet lost rate 43.5% and the Asus RT-AC88U is just abt 1.8 meters straight away without any kind of obstructions. Yep, it has been like this for almost 2yrs. Have you gathered enough courage to admit Yeelight just another Chinese brand that making shxtty products?
@_guofeng, We discussed same issue in multiple threads on the forum. As result of the discussions it seems that by whatever reason lights periodically (several times a day) drop IP and try to get it back from DHCP service on router (I have 5 Yeelight lights (450/480/650), and I see from the router log that they drop IP address and connection +/- simultaneously, within few minutes). In most cases they get IP back successfully (I assigned static IP for all devices on the router), but some times not. And if not - then I have to physically switch it off / on to restart.
I would be happy to participate in any testing / investigation to find out how this dhcp issue can be resolved (manual assignment of IP / new firmware testing, etc)/
@_guofeng, I do not see any updates for the lights. I did logoff / logon for Xiaomi account, tried both from Yeelight app and from “Mi Home” app - no updates avaliable.
I’m using China mainland servers. May be I need to change something in config / apps settings to see firmware?
Same problem here. I have a light group for two of my led strips, one is instantaneous, but my newer strip, which I had just set up takes around 8 secs for it to light up via the Yeelight app and Google Home. My ID is 1887348638.
