I have an Entities Card which shows Thermostat status including whther Hold is on. I can change temperatures but if a Zone is set to Hold from the thermostat, I can’t see any way to turn it off from HA.
I’m also getting this error. I don’t know if it matters. Everything works except arming alarm. Did you get yours to work?
No. I actually changed it out for a DSC die to the board going bad just after this post.
See my other post to you concerning the custom Sons card……
