Edit to add: This is working again as of 2022.9.4. Thanks!
Since updating to HA Container v2022.9.0, I can no longer set the temperature on my Nexia/Trane XL824 from Home Assistant. I’m using the built-in Nexia integration. Here’s what the climate.thermostat entity looks like.
No. See debug logs for the climate and nexia entities below. Note that I can set the temp using the Climate: Set temperature service, but cannot set it through the UI climate entity card.
