I was looking for a binding for the Bosch EasyControl CT200, which was recently installed in my home.
I have found it has an accessible API, and the how-to to get to it is described here (tested it an it works!)
Unfortunately I do not know yet how to program a binding myself (even though I am an experienced programmer in multiple languages), and I fear that even setting up an openhab development environment will take more time than I currently have available.
Maybe more people run into this, so for now this is not much more than a Feature Request - sorry for that.
Regards
