Maybe this helps
- turn on upnp in configure gets you the raspberry as entry in the modules list, at least this one should show up
- other devices are detected by HG after a while, turning them from standby to power on helps for AV Receivers
- some devices claim to be upnp capable, but they just have a thin-client to connect to servers, these do not show up on my system, too
- devices detected get a long hexadecimal identifier in the add modules widget
cheers
