Error on CasambiBt import

[aschwith]

Importing the CasambiBt package via

from CasambiBt import Casambi, discover

results in an error:

Datei '/home/smarthome/.local/lib/python3.8/site-packages/CasambiBt/errors.py', Zeile 14
function ConnectionStateError(), Exception: unsupported operand type(s) for |: 'type' and 'NoneType'

Test is run under python 3.8.6.

Any help is appreciated. Thanks and best regards

Python 3.9 or newer is required.
