I just excluded it, but I'll try to do a factory reset on it. As far as I can tell there isn't a parameter to enable / disable crc16.
I tried a factory reset. Also tried connecting it to my Fibaro Home Center to see if it had a firmware updated. It did not and still wants to talk mostly with crc16. I'm not sure what is unique about this model, but I think most of my Fibaro switch modules use crc16.
Trying to control it in Hubitat doesn't work of course:
I don't know how involved the CRCEncap implementation will be, some of these classes are cake, some not so much.
In any event I've added to my white board...
No problem, personally I'm not in a huge hurry to get it. As long as it is somewhere on the list.
