According to the docs (note: I don’t use this binding), there are 2 steps in the discovery process:
Identification of the Bridge (a special kind of Thing) with only the 4 channels that you have
Following the Bridge scan, another Discovery should happen and you should see more Things (linked to the Bridge) representing the Zones. In these “Zone” Things you will have many more channels
If the 2nd autodiscovery doesn’t work, you can try to define your Bridge & Things in a file
Ok, in fact, I seemed to overlooked that! Thanks for the hint.
With reference to your documentation link it obviously does have detected the bridge “yamahaAV” but not yet the zone. I ran searching for things again on the yamaha binding but the zone is not coming up.
Any idea how I can initiate the auto discovery on the bridge now? (I checked the doc and other threads but could find anything).
I would: delete the auto-discovered Thing and create a /etc/openhab2/things/Yamaha.things file with my Bridge and my Things (just like the docs example for manual configuration)
If you use the same Thing UID as the one that was auto-discovered, you won’t see anymore a newly discovered Bridge in your Inbox (it will be auto-ignored)
