No improvement. It is also the same on several computers/iPads, only the “completely reinstall” HA shows the new cards. Restart etc. of course already tried everything.
the theme is the same (HA Theme) - but the yaml code mybe not (i dont know, but i have in the “old” HA mqtt and other configuration, the new one is only for testing…
Where can i see in the yaml, if there is a problem with the “thermostat cards”?
