LIDL / Livarno Lux light bar RGB+CCT (black/white): Cannot set color anymore

[Alex23030]

What happened?

Hello,
since i updatet my Z2m in home Assistant on 2.11.0 i can not change the color of this light anymore. It still can be switched on and off, but it is only white. I removed the 3 Lamps, started z2m new and add them new, but it changed nothing.
What can i do?

Same problem here. Sending the effect "channel_change" enable the rgb again for short time.
