Hi
Running HA core 2021.10.2 with Zwave-js2MQTT 0.26.0
I’ve got several Fibaro RGBW-1 z-wave modules doing this very happily (several entities show up, with an RGBW one that controls all 4 channels, and a separate light entity for each channel, so you can use that output in isolation for a single strip light).
I can’t get either of my RGBW-2 modules to do this. Five light entities show up, but only the first one turns any LEDs on, and it shows up as an RGBW device with colour wheel etc, so you have to pick the right colour to selectively dim/use each strip! The remaining four light entities do not seem to do anything.
I can’t find any clues in the zwave config for the device, or manuals, or forums so far
