Hello @lucamichetti I have recently installed the software. I am sorry that you have not received sooner a reply to your quest…
The new software application created by @titilambert, which by the way I highly respect for the great work that was done is not an integration (yet). The only integration portion to the application is that it can be ran using the Home Assistant payload format: MQTT Discovery for its output.
Like I said this is an application that requires to be installed separately. The thing about home assistant and kudo for its simplicity in its integrations installations but at the same time it can be misleading or get a little more complicated in situations such as for this installation. Hence possibly why you did not get an answer?
For me or anyone else to help, you will have to provide more details to your home topology including home assistant and any other linux boxes you may have access to?
