Nuki Opener BPT Agata C

Good morning, in the office we have the intercom BPT AGATA C.
compared to other models already present as compatible, this model communicates via BUS with only two cables.

I tried to follow the generic BUS guide with red and black but I can’t put them in communication, did anyone succeed?

It includes photos of the actual wiring diagram.



Same problem…any update?
