Yeelight Ambilight wrong brightness

Hello,

I integrated several Yeelight devices (bulbs and ceiling) which are working fine, but i’m facing an issue on ones of the ceilings (YLXD02YL), which is discovered as a ceiling4.

As this ceiling has 2 lights (main + ambilight), the integration created 2 different entities for this device.

Globally, they are both working fine (on/off, color, temperature), except for one case:

Having both on, if i turn off the “Ambilight” light in HA, then “main” light has a brightness to 0 in HA (in real, and in the yeelight phone app, the status is correct), and of course brightness could not be changed in ha anymore.
If i turn on again, brightness becomes again available.

Globally, if “Ambilight” light status is off, then “Brightness” value for the “Main” light is always 0.

Anyone has the same problem and found a solution?

Something related to the “nightlight” entity also created? This one appears always off)

Thanks and have a nice day.

Someone else has this issue?

Small up for this issue?
