Quick update. I was able to get it too add to my c-5 (still not recognized as any kind of device), and then try the Zooz Smart Dimmer driver again, and I can now turn off / on the lights, and with a couple of configures it now seems to populate the firmwareVersion. The Current Status doesn't seem to update properly though. (it never updates the status unless I click refresh).
Still testing if it will work on my C-4.
Here is the log output when I included it and did the configures in case this helps.
