Introduction
In my living room I have a group of four LED lights and a scene controller. I can manage to switch the lights on/off and change the colour temperature, but the brightness control doesn’t seem to work. Ideally I would also like to learn how to use the scene presets.
Technical environment:
Home Assistant 2025.4.4 running HAOS on a Dell with 8Gb RAM
Zigbee2MQTT 1.41.0-1
SLZB-06
Illuminize Scene controller: Iluminize 511.524 control via MQTT | Zigbee2MQTT
Skydance LED controllers Skydance WZ5_dim_2 control via MQTT | Zigbee2MQTT
Binding
In z2m in the “bind” settings for the Illuminze scene plate I have bound “Source endpoint 1” four times, to each of four Skydance LED controllers. The clusters ticked are OnOff, LevelCtrl, LColorCtrl, and Scenes. Identify, Groups and Touchlink are not ticked.
Outcome
When I press the main On/Off button, it toggles all four LEDs on/off correctly.
When I touch the colour control, it changes the color temperature on all four LEDs correctly.
When I press the brightness up or brightness down buttons, nothing happens.
Z2M log output
I am not sure why I am getting anything in the Z2M log at all, because I’m binding directly and trying to bypass Z2M (this whole exercise is my fallback for when I’m having problems with Z2M or the Sonoff adapter). However, I am seeing messages that show first the brightness setting being changed, and then the colour setting being changed.
Given that I am seeing brightness settings changing in the Z2M log, I am confused as to why this, and this alone, is being ignored by the LED controllers themselves?
If anyone has any ideas, or suggestions for further tests I could run please do reply, I would be very grateful.
