I installed my Nuki Opener to a BtCino intercom system following the Generic bus option since I only had two wires to work with.
When setting up the app software I could enter that I wanted to open two doors and both could only be openend after the bell rang and an single button would then open the door.
Since I was alone during this setup I could not do this for the first door downstairs en just did for both doors the same procedure (ring bell and open) at the door upstairs. This has worked for a while although the app gave me an PIN error so I could not do anything in there. Since the upstairs door worked I just left it like that for a while. Until yesterday when I had a power and wifi loss and had to do the whole setup again.
To my surprise I could not select two doors anymore. When setting up Generic → BtCino I can ring a doorbell and open, but then it continues to "“Please step outside to the doorbell next to the front door” and when i then ring the doorbell next to the upstair intercom door, it just shows the spinning icon and it times out.
How can i set up the Nuki so it works? Does anyone know? Do I need something different than the Generic->BtCino?
