Seamlessly Integrate Viessmann Climate Solutions

In keeping with its purpose, Viessmann has smoothed the way for cooperative development projects in the area of smart home automation.

API portal

Via the new API portal (Application Programming Interface), developers can quickly and easily add heating and ventilation systems in third-party applications for example, in smart home systems. Users benefit from the seamless integration of devices into their solutions.

For Viessmann, the API portal is a window on new fields of application that promote innovation in the developer community.

Creative, innovative, and individual

With the new portal, developers can work together with Viessmann to realize tool-based approaches

With the new portal, developers can work together with Viessmann to realize tool-based approaches and solutions creatively, innovatively, and individually. The portal thus provides unique access to data in Viessmann’s Integrated Solution Offering.

For example, it allows developers to adapt parameters for energy saving and CO2 reduction based entirely on individual requirements, or to design apps for complete control of home automation.

Access in just a few steps

The Viessmann API portal is available at developer.viessmann.com. In a few steps and less than five minutes, you can begin calling up the Viessmann APIs.

• Discover the APIs: All Viessmann APIs can be found in the API documentation. Under “Choosing the right API,” users can find instructions on finding the suitable API for their specific case.
• Create an account: To log in to the developer portal, the user needs a Viessmann account. This is the same account that users already use to log in to the ViCare app, for example. If users don’t have an account, user can also register online for access to the portal.
• Call up the API key: An authentication process takes place before the user can use the APIs. This involves calling up the API keys and creating a new client.

Start development for free

Access to the basic functions of the Viessmann Developer Portal e.g. heating system basic functions, ventilation, and hot water storage tank functions, and a basic set of API calls is free of charge. This allows users to start developing and integrating their applications immediately.

In addition, various paid offerings will soon be available that provide access to even more functionality or an even higher number of API calls.
