Before using Zigbee bindings, I had a Home Assistant automation that would get the brightness of the Zigbee group and then apply it to the brightness attribute of the Inovelli switch. And that worked great.
Then I went ahead and setup Zigbee bindings, using the clusters genOnOff and genLevelCtrlbut this creates a feedback loop with the automation above because the brightness attribute of the Inovelli switch now controls the brightness of the group. If I disable the automation and if I were to only set all the lights in the group to the same level that would be fine, but if I use a scene or control individual lights in the group (instead of the group itself), the LED bar won’t update to the new brightness level of the group. Is there a workaround for this?
I tried simply using genOnOff cluster but then when I press ON on the Inovelli switch, it sends the brightness command 255 which for Philips Hue bulbs means reverting back to last know brightness value before turning off. It seems you need to use the genLevelCtrl cluster to be able to use DefaultLevelLocal parameter.
