I will try to answer your answer I just auto-translated. 
The current state of compatibility to intercoms can be found at Opener | Nuki The Smart Lock (or https://nuki.io/fr/opener/). If your model is not listed there you can still submit a request so we can see that there is demand for that model and check compatibility (based on that demand).
Especially with BUS intercoms it is hard to give general statements without doing some research and you have to understand that there is broad demand for different models at the moment.
