Got 2024.3.0 as update today, after reboot 3 of 4 BTE configurations wont fire up anymore. Maybe this is form their old config, or there is new incompatibility.

Described problems seems the same as in #1304

[r-eckert]

I had the same problem. In my case this was due to Home Assistant removing the hourly weather forecast entity. My thermostats were referring to an entity that no longer existed. Just configure the thermostat to point to the regular weather entity and it works again.

[LinuxfarmerHH]

Can confirm r-eckert solution to this problem, so the 1.4.0 stable work again. The weather.hourly entity does not exist anymore in the core update.
