@bcopeland - here is another that doesn't work correctly under JS. The Zooz RGBW Dimmer. My Fibaro RGBW device uses it and I have similar issues to the other drivers.
- Command component on/off from driver - component turns on/off but does not update state to on/off
I've tried using the driver 'Fibaro RGBW' but it doesn't work (presumably that's for the old 1st gen Fibaro device). I've also tried using the 'Generic Component RGBW'. Again that doesn't work just logs 'missing signature of method' errors.
Right I'm completely screwed with this driver and with the Fibaro RGBW2. I've got the FGS-223 and FGS-224 working by modifying them myself, I've got the Fibaro Plug working by selecting another suggested driver and I've spent 4 hours rewriting rules to NOT use the Smart Implants inputs as they don't work properly.
However this RGBW2 has me stumped - none of the system drivers work properly. It would probably be the same easy fix but that's impossible because the source code is unavailable. The possible (but more complicated) community drivers for the Zen31 also do not work and sifting through 2000 lines of code with ChatGPT is no fun.
I've now 4 devices that are basically scrap without a working driver 
Can you go to:
/hub/zwave2/ccdebug/true
This will turn on more debug logging specific to ZWave-JS value parsing..
If you could perform your actions again after the logging is running then PM me your hub ID so I can pull the logs..
To disable:
/hub/zwave2/ccdebug/false
@bcopeland - is there any news regarding the issue yet? Thanks.
