I couldn't find anything with a forum search, so hopefully I didn't overlook anything.
I have setup LinuxMCE 1204 (I couldn't get 1004 to work on my hardware). I'm using a Aeon Z Stick v2 as the interface, and a Radio Thermostat / 2gig CT100 thermostat.
The system sees the thermostat, and I can set heat/cool/off no problem, and I can set a cooling setpoint, but not a heating setpoint. It just ignores it. I get this error in the logs when trying to request a set point:
No such setpoint 'Heating 1' found!
When adding the thermostat, it tells me (in part):

In addition, setting the fan mode has no effect
