GDX5 Intercom integration

Hey, also curious if anyone else has tried this or had any other success with GDX-5?

@Juergen - do you know if there’s any official update on getting this intercom/system to work with Nuki?

Thanks.

Did anyone else managed to wire it up successfully? I’ve tried Dan’s suggestion to solder Red wire to G pin and Blue wire to SW3 (Top right pin) and use analogue mode but with no luck
