actually i got a problem with the yamaha receiver binding: after changing the state of a switch or another item the receiver doesnt execute the command as expected. there is no error in the logs, the receiver just doenst do anything - even the items in openhab didnt get an update after changes at the receiver itself:
2018-05-25 20:07:28.061 [ome.event.ItemCommandEvent] - Item 'RXV775Main_Zone_Zone_channels_Mute' received command ON
2018-05-25 20:07:28.063 [vent.ItemStateChangedEvent] - RXV775Main_Zone_Zone_channels_Mute changed from OFF to ON
2018-05-25 20:07:31.591 [ome.event.ItemCommandEvent] - Item 'RXV775Main_Zone_Zone_channels_Mute' received command OFF
2018-05-25 20:07:31.594 [vent.ItemStateChangedEvent] - RXV775Main_Zone_Zone_channels_Mute changed from ON to OFF
the state of the thing is “UNINITIALIZED - HANDLER_CONFIGURATION_PENDING” but i dont have an idea what to do now. scanning for new things doesnt bring up any results.
If you did recently an update, and defined the bridge/thing via text file, there is a chance that you missed the breaking change: In current snapshot, for yamaha binding the parameter names changed to host (formerly HOST) and zone (formerly ZONE)
