Supported devices by the Tahoma Binding

Hi.
I have a connexxoon with window app and it is no longer supported using tahomalink (that’s what somfy was talking to me today because I switched to the new firmware version of the box).
Since I need to include by shutters in openhab I need to buy a new box. My questions is which one is the best supported box today (and for the future) to use the io products. Is Tahoma Switch working well with the Tahoma binding? Or shall I buy the legacy old Tahoma Premium?
Thanks, Markus
