Problem to integrate "Devolo Home Control" in Home Assistant

Hello together,

I’m new to Home Assistant and have problems to integrate “Devolo Home Control”

My configuration is:
Version core-2022.2.2
Installationstyp Home Assistant Container on Synology DS218+
Entwicklung false
Supervisor false
Docker true
Benutzer root
Virtuelle Umgebung false
Python-Version 3.9.7
Betriebssystemfamilie Linux
Betriebssystem-Version 4.4.180+
CPU-Architektur x86_64
Zeitzone UTC

When I try to integrate Devolo Home Control
I have to enter my eMail address and password,
the field “My Devolo URL” is already preset with “

After hitting the send button I receive the message “Success - Configuration for
Devolo Home Control is created” and a “Done” button.
When I click the button the integration is shown but with an error message “error during setup - check the protocols”

The log show following stack trace:

Logger: homeassistant.config_entries

  File "/usr/local/lib/python3.9/site-packages/devolo_home_control_api/properties/", line 43, in __init__ = kwargs.pop("zones")[kwargs['zone_id']]
KeyError: 'default_hz'

Can someone please tell me what the problem is?
Any help is appreciated.

Thank you

Hallo together,

my installation of Devolo Home Control worked fine for a long time, but since approximately two weeks I have the same problem. Has anyone already solved it?
