If you mean that the options listed here:
lacks BLUETOOTH, COAXIAL, DIGITALIN1, DIGITALIN2, ANALOGIN, ANALOGIN2 - then I think you should just add it to this list, which is already a list of all possible input sources across all models (and evens brands).
Filtering this list should be done outside the binding, at least with the current design. I have not read the source code, so there is a chance I’m missing something, for example if the binding would dynamically manipulate this list based on detected model from the MAC address, but I wouldn’t think so.
