DHW Thermostat missing?

[MrEarl]

There used to be a Thermostat for hot water, which became unavailable about two weeks ago.
It's still listed in the controls section of the DHW device, but if I click on it I see the following message:
"This entity is no longer being provided by the luxtronik2 integration. If the entity is no longer in use, delete it in settings."
Is this expected due to recent changes?

I'm not quite sure which additional information I should provide, so if there's anything needed, just let me know.

I checked mine and it's still there. Is there an error in the logs? What happens if you install the previous version?

When I install the previous version (2025.12.31-beta), the thermostat reappears:

Note that DHW mode is now unavailable. I guess it's the "Enum-based DHW mode select entity" introduced in the latest version (2026.01.27), so this is expected.

After installing the latest version (2026.01.27), I see this error in the log:

The DHW mode select entity is available, but now the thermostat is gone:

Strange...
Could you make an issue with info from the previous post?

[MrEarl]

Sure.
