Any ideas? 
Thanks for the help.
I can’t quite say for sure, but it looks like this bTicino unit uses the 2-wire SCS bus system. If so, compatibility with the Nuki Opener will be hit or miss depending on the quality of the wiring in your house. It might work or it might not, the only way to find out is to try it out.
Unfortunately, the Nuki Opener does not fully decode the bticino SCS protocol, it only captures/replays packets, which might work in some cases, but did not work reliably at all in my case.
I have written quite a lot about the underlying issue and the fix that I ended up using:
- Nuki Opener with an SCS bus intercom (bTicino 344212) (2020) - Michael Stapelberg
- Fixing the Nuki Opener smart intercom IOT device (on the BTicino SCS bus intercom system) (2020) - Michael Stapelberg
- Make your intercom smarter with an MQTT backpack (2021) - Michael Stapelberg
Hope this helps, and I also hope that some day Nuki developers will actually implement proper bticino support…
