Trane XL850 compatibility

It is not possible - had to use IFTTT and created some virtual switches on HE that triggers automations on ASAir cloud platform. Crude, not local, but it works most of the time.

[RE-RELEASE] Nexia Thermostat Manager (Trane Home)

I took @thebearmay’s app (v1.0.3) and extended it (v1.1.0) to work with the Trane Link UX360 thermostat. It likely works with other newer Trane thermostats as well, but that is the only one I have to test with. I didn’t remove the existing functionality; it now has 2 distinct methods of thermostat discovery. It’s been a really long time since I’ve coded, so I relied heavily on Codex (chatGPT) to help me. This is the first time I’ve released Hubitat code as well. The key changes are: Updated…

Very cool! I look forward to trying it out. I eventually got Home Assistant up and running with a nice integration there, and have it shared to my Hubitat through HADB. But I’ll give this a shot soon! Thanks for doing this!

@waterboysh I just installed it via HPM, and it seems to work like a charm!

Thanks so much for developing this! One less hop through Home Assistant is never a bad thing!

So far the only thing I’ve done with it is refresh and see that it had accurate info that matched my thermostat, and then I changed the setpoint in Hubitat and watched it update on the UX360 in realtime. If I run into any issues with further use/testing, I’ll let you know in the main thread.

I’m glad to hear it’s working for you! This is the first time I’ve ever released any code publicly so I was a little nervous about it. I used to code a lot, but have done very little for about 15 years now. It was really neat using Codex… but I don’t think I could have gotten it working with zero prior experience. I still had to do quite a bit of tinkering, but the difference was instead of me trying different things I’d explain to Codex what needed to change and it would make the changes. I had to open the Trane Home web portal and use the developer tools in Chrome to inspect the network traffic too. It’s possible if I had told Codex I had no idea what I was doing it would have dumbed down what it told me and walked me through getting the data, but I don’t really know. Just let me know if you notice any problems.

The next thing I want to do is develop a companion app that tackles two problems.

1. My variable speed system only does upstairs. During the day I sent the temperature to 78 because generally no one is upstairs. But I’ve noticed that the humidity is getting pretty high (like 65 - 70%). Instead of just lowering the cooling setpoint, I want to automate adjusting the cooling set point so there is never a large demand response needed and it runs at a slower speed.
2. My other issue is also related to raising the temp higher during the day. When it’s time to start getting the kids ready for bed, I want the temperature to be lower. But even setting it 2 degrees lower often causes the compressor to run at a speed > 80%, and often just at 100%. I want to be able to say “I want the temperature to be 74 by 8pm” and have the thermostat slowly adjust the cooling setpoint down over time, starting at just the right time, so that the temperature goes down slowly and the compressor never has to ramp up to a high speed.
