It seems that the new switches are not yet supported by the binding. I had raised request [boschshc] Support for new Shutter/Switch II · Issue #14562 · openhab/openhab-addons · GitHub a while ago but not seen any response yet. Though my other devices are working fine.
I think we need to wait until the new devices are picked up by the developers. Unfortunately I do not have the skills working on the code myself.
