Hello, just saw that we are talking about the same model.
See my post with the experience I had.
You can see that in online-shops and also bticinos official catalog, the Model 344612 is called “Classe 300 V13E Video” which is listed by NUKI. But I think thats an issue.
However it didn’t work with the Wireing presented in the App and I had to use basic wireing and model “Generic - BUS (Bticino)”.
