Bit flags are often use as error-code mapping.
In my case a 16 bit, used for several different errors that can occure at the same time.

A good example was desribed in this issue by @maniac-semal

But: if everything works as expected, no bit flag matches and the sensor gets status "unknown" or, and that is the problem, it stays on an old error code.

Describe the solution you'd like

Feature request:
adding a value, if none of the bit flags matches, like "0" or "none".

Workaround:
modification of conversion.py like described by @maniac-semal (thanks).

Describe alternatives you've considered

unfortunatly none

Additional context

none
