Bticino-Legrand gateway stopped to work

Hi Guys, in last July I bought some actuators manufactured from BTicino Legrand living NOW family, based on a gateway which talks with some domotic devices such as roller shutter commands.
HA immediately recognised it as a new device based on an integration, and automatically added all entities onto my Hassio instance.
Suddenly yesterday they stopped working with HA, no way out. The system by itself works properly (with its own cloud) , but home assistant is blind. I tried to figured out what was the integration, and I remember something such as “home kit” but by searching a new “home kit accessory” integration HA could not discover it anymore…
Could anybody help me?
Thanks a lot in advance.

Hi Stefano, I have the same problem … did you find any solution?
Let me know, ciao.
