What will happen if I update the firmware of my opener from 1.2.7 to 1.3.1 but do not reconfigure it? I have a Bticino 344252 which already works. But in the changelog I also read that the new firmware increases the stability.
Try several times. I am in your case and something is trapped when you try to reconfigure. I spend 1 hour in reconfigure my fermax VDS, and at last after several tries, go back ok. Reset Opener and delete manually from bridge, and try to config with bridge manually in the bridge config app, not in the config process in the app. Dont desesperete, at last the good config back in my VDS Fermax, so it could possible in others intercoms.
