The difficulties in control in this building are that it is just a 24 x 30 metal shop kit with spray-foam insulation. We're living in it until we're able to build a new house.
The "HVAC System" in the bedroom is a window air conditioner on a zigbee outlet.
The "HVAC System" in the 24 x 20 main area is a larger window unit that is self-controlled and that doesn't quite keep up with a Texas heat (you can see the outdoor temperature there) without arranged help from the bedroom unit.
I'm not home right now, but looking at this I'd guess my wife left the bedroom door closed when she left this morning so the bedroom HVAC isn't helping the living room HVAC out at all.
