If your device is not supported, but it is a Viessmann device, I’m very open to integrating your device. In this case, please contact me using PM, or a reply to this topic and I’ll guide you towards the information I need to integrate your device.
I’ve developed this app in a full open-source mindset, the source code is available under a GPL-license, meaning that everyone is allowed to use it provided that they release their source code under a GPL-compliant license. You can find the source code of the application in my GitLab repository at:
Any issues which are found in the app, or features which I’m still considering to be adopted, can be found in the GitLab issue tracker at:
Anyone is free to contribute towards the app, you can simply fork the repository on GitLab and create a merge request with your changes, I’ll review them and most likely include them as part of the app.

I really hope you enjoy the app, and any feedback is always welcome! I try to respond to all requests as soon as possible, but be aware that I have a regular job too, which might imply that sometimes it takes a bit longer then on other times.
Kind regards,
