Nexia / Trane integration is not working as thermostat

[iskiselev]

The problem

For several month, Nexia / Trane integration stopped working as thermostat - I still see some devices / sensors there, it shows me room temperature, but does not create thermostat device.
I have Trane XL824 and XR724. Integration perfectly worked with XL824 before. It seams Trane changed something - at nearly same time, I noticed that XR724 visible in Google Home and some information available in Home Assistant (which was not available at all before) and XL824 stopped work as thermostat.

What version of Home Assistant Core has the issue?

22.10

What was the last working version of Home Assistant Core?

Hey there @bdraco, mind taking a look at this issue as it has been labeled with an integration (nexia) you are listed as a code owner for? Thanks!

It looks like they renamed a few things from the diagnostics

I don't have the bandwidth to investigate this or make the changes to adapt to what has changed on the cloud service right now but if you have the time to do a PR to the lib I'll find the time to review and test it on my system.

[iskiselev]

I will try to look into it, but it will take some time for me - I don't know how to try my changes / debug with HomeAssistant yet. Looking into JSON and call stack shows me that my guess about XR724 was correct - it is now returned in the same device list, but don't have system_status / operating_state fields (but zone inside has field zone_status "auto", which is empty in XL824.) I will check how json looks in different modes, but probably first hotfix should be to ignore none-supported device, instead of failing. - as now I don't have access even to supported XL824.

[bdraco]

Usually I dump the diagnostics into a test fixture and then go through and fix whatever is broken

I have several of the XR724 in an office setting and I was working to put them in HomeAssistant. When I add them in they show up as basically read only devices. Is there a chance that HomeAssistant will be able to control them?
The Nexia app has the ability to do so, so it seems there is some pathway to them receiving changes.

It should be possible to add support for them if someone wants to invest the time to make it happen.
