Bticino living now

I’m tryng to integrate the living now components into home assistant.
For some reason, I see everithing with the home kit integration when I reconfigure my ip address lan.
But unfortunately I had to remove everithing because after few days , all the switches became double, I dont know why.
Thinking that was easy reconfigure that, I deleted the components ( switches and termo ) , but I dont know how integrate everithing .
How can I do? I dont have conbe usb. All worked with the bticino gateway k4500c . If I didnt see with my eyes , probably I start to think to use conbee and other kind of integration. But Im sure it works with the auto detect and homekit . I dont know whats happen.
There is someone that use bticino with standard integration?
