ich habe jetzt die Viessmannapi Version 2.4.3 von "https://github.com/TA2k/ioBroker.viessmannapi" manuell im iobroker installiert und alles funktioniert wie vorher.

Hallo Zusammen,

seit Anfang August werden die Daten von meiner Wärmepumpe nicht mehr im iobroker über die Viessmann API übertragen.
Laut dem Change Log wurden die API Endpoints aktualisiert. In meinem Logbuch im Developer Portal wird auch kein Zugriff mehr dokumentiert.

Muss jetzt der Adapter im iobroker angepasst werden?

Domain Change for the Viessmann API
As part of the continuous optimization and modernization of our services, we are currently in the process of switching our applications and websites to the new domain viessmann-climatesolutions.com. This change will also affect the domains for resources such as the Developer Portal and the API Documentation.

For your integrations, this requires the following technical updates:

1. API Endpoints:

The base URI for all API calls is changing. You need to update your code to use the new domain.
Old: https: //​ api.​viessmann.​com/...
New: https: //​ api.​viessmann-climatesolutions.​com/...
2. Identity and Access Management (IAM):

The domain for our identity services will also be updated. This needs to be updated in your application to ensure authorization continues to function correctly.
Old: https: //​ iam.​viessmann.​com
New: https: //​ iam.​viessmann-climatesolutions.​com
3. API Response Body:

The uri value within the JSON response from the Features API (/iot/v2/features/...) will reflect the new viessmann​-​climatesolutions.​com domain in the future.
The API endpoints under the new domain are already available, and we ask you to please use the new addresses with immediate effect. The old viessmann​. com domain will be deactivated during Q4/2025, by the end of the year at the latest.

We understand that these changes may require adjustments to your existing code. To assist you in this process, we recommend referring to the API documentation.

Moin ich habe das selbe Problem. Bei Viessmann im Changelog steht das die API Endpoints aktualisiert wurden. Daraufhin habe ich das Probe Abo abgeschlossen und den Client aktualisiert. Vorher konnte ich die Daten jede Minute aktualisieren, nun werden keine Zugriffe im Delevoper Portal registriert.

Könnte es sein, dass die ViessmanAPI Instanz im iobroker angepasst werden muss??
