Liebe Modulentwickler,

ich hab neulich von Viessmann die Ankündigung erhalten, dass die bestehende URL für das Viessmann API abgeschaltet wird:

Dear Developer Portal user,
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.

Frage an unsere Entwickler: Ist diese Änderung bekannt und gibt es schon einen Plan, wann unser Modul entsprechend umgestellt wird?

Mit besten Grüßen

Pete Salomon
