Hey together.
I also have a Elvox intercom system in my new Appartement. Model is 6700 -6711.
As far as i can deduct this information the Due Fili Bus is used for that system.
I wrote a extensive post about the problems here: Bluetooth connection Error during opener setup?
I m also stuck at the recognition of the Door open signal recognition which doesn’t work.
I would really appreciate any progress on this matter!!!
