After update to 2021.4.1, miele integration gives errors at start and while running

Looks like the "AssertionError" became an "AttributeError" in HA as the exception is only thrown for "devices" that I have manually disabled.

@marconfus what type of devices did you hide? We had this error before and I think I fixed it on all devices but might have missed some.

I disabled the irrelevant temperature sensors like "sensor.washing_machine_target_temperature_1" or "sensor.freezer_temperature_2". After adding some debug code I saw the exception is raised only for these device objects.

@marconfus allright I'll take a look this week, thanks!

+1 get the same error after #39 was fixed.

Should be solved after next Dev to Master PR :-)! Please let me know if not the case.
