your device NOT response to all the C3 device query message, so HA can't get enable it or control or get the device status.

below is the error all the query cmds failed in your debug log file:

please try to reboot your device and HA to confirm again.
if it still have the same error result, there should be some issue exist, but I'm still not sure now.

Thanks for the quick reply!

I restarted both HA and the WaterHeater, removed it from HA and added it again. Same behaviour. Is there something I can change in the configuration, that might help? Here is a screenshot of the default:
