I recently got a pack of 4 color 1S light bulbs, but one of them is having issues. It frequently shows a different color/brightness than what I select in the app, it will change color seemingly randomly, flicker on/off, disconnect from wifi, or just turn off sometimes without my input.
I tried factory resetting it multiple times and multiple different sockets, but nothing is working.
It seems that this is a firmware issue because it is shown as yeelink.light.color.2 on its device info in the app, whereas all my other bulbs show yeelink.light.color.4. Is is possible to get a firmware downgrade or is there a known fix to this?
