Insteon Hub Local discovery question

Hello, i’m kind of new to HA, but I have some trouble setting up my insteon hub (V. 2014) to be able to see something on the frontend.
My question is, apart from setting IP, Username and password of my Hub in the Configuration.yaml is there something else that need to be installed or configured?
I thought that the discovery service would be able to pick up my devices automatically, but nothing appear on the frontend.
I had a look at the logs, and it seems to detect my devices without putting any error message, so it seems to be communicating but it is not doing anything with it…

Tanks for your help!
