I just got two Trane HVAC systems installed (upstairs and downstairs) and it uses the UX360 thermostat. I already hate this thing but I’m locked into it because it’s a communicating VRF system.
I was able to get the system to show up in HA using the Nexia integration. It found the Upstairs and Downstairs thermostats, but only a “Zone 1” that seems to be associated with the Downstairs thermostat. I guess the Zone is where the climate controls are, and the thermostat is just sensors.
I don’t have a zoned system, so not sure how to get the Nexia integration to give me a Zone for upstairs too?
