[Bug] Fresh HB instance, device not found
Hi, I'm trying to add Homebridge-shelly to a fresh new instance of HB on a rpi 4 4gb but it can't find my Shelly1 device. The device is successfully reachable from LAN using its IP (no auth required) and it works normally from app (even from outside the LAN with cloud connection). Also, the command shelly-describe seems reaching the device normally (and details look corrects) so I can't really understand why it cannot find it. I tried also to leave network interface empty or put either HB IP address and network interface name, without success. What could I try? 

Thanks in advance!

Andrea
