I have three RGBW controllers, each controlling three mono-chrome LED strips. Control using the app or GUI works fine, both on/off and dimming. For direct physical control, I use switch number 2 on a Fibaro dimmer installed in a wall box behind a double momentary switch. Switch number two on the dimmer is associated with the appropriate output channel on the RGBW controller. The way this is supposed to work, is as follows: When the switch is operated, the information is "shared" through the association, instructing the RGBW to act accordingly. For on/off this works fine. For dimming, however, I am not able to control the RGBW. When I push-and-hold the switch, the LED strip starts to change after a short delay, but then quickly "jumps" to the extreme position (0 or 100%). It seems the z-wave communication between the dimmer switch and the RGBW controller is too slow to handle a dynamic dimming situation. There is no load connected directly to switch number 2 on the dimmer.
I have tried to alter the parameters on the RGBW controller, but I have found no setting that allows me to do a controlled dimming of the LED strips by using the switch. Any suggestions?
I may add that for one LED strip, I tried a similar setup but with a Fibaro double switch (not a dimmer) as the parent device. This did not work at all, so in this case I use a work-around through a script triggered by the switch actions (push, push-and-hold etc.). But for the ones with a dimmer as the parent device, it seems I am very close to making it work properly and I would like to keep the "association" method if at all possible.
