Got this added to OpenZwave but NoJoy. This unit does not exist in open zwave so while it is recognized sensors and control is not possible. I am thinking about adding general trane thermostat definition to this and see what happens.
This person added it to HA and noticed this. When I saw this I decided to take a look
On a side note, the XL824 can probably just be added into the “manufacturer_specific.xml” file and will just work.
