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:
2. Identity and Access Management (IAM):
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.
Support Channels:
If you have any questions or require further assistance regarding these updates, please don't hesitate to reach out here in our forum or send an email to developer@viessmann-climatesolutions.com.
We appreciate your understanding and cooperation as we continue to improve the Viessmann API.
