Viessmann API binding for OpenHAB 4.0 [4.0.0.0;5.0.0.0)

[sven1234 (Sven)]

I use the other Viessmann Binding:

Viessmann Binding [5.0.0;5.9.0)

[logo] This binding connects Viessmann Devices via the new Viessmann API. It provides features like the ViCare-App. Changeling Version 5.1.0.202511200020 Add support for heat energy and current Version 5.1.0.202511161327 Fix ´One Time Charge´ Version 5.1.0.202510202037 Fix ´heating-burners-0-statistics#hours, heating-circuits-0-heating-curve#shift, heating-circuits-0-heating-curve#slope` Version 5.1.0.202510190605 Add unit ´kilowatt´ Add unit ´revolutionsPerSecond´ Version 5.1.0.20250…

But it also fails to connect and I cannot login to the developer portal either. It shows error.saml.failed.

The Viessmann App cannot connect either.

So I guess we have to wait until Viessmann IT gets to work and solves the issue.
