@Dim, you convinced me. I got rid of the auto discovered bridge and manually added everything as described by @Udo_Hartmann here [SOLVED] Yamaha binding - manual thing config does not work
For those who want to achieve the same thing. Here is exactly what I did as an example:
I used the following setup:
I created a “receiver-wozi.things”-file and added
Bridge yamahareceiver:yamahaAV:wozi "Yamaha Receiver Bridge" [host="receiver.ip.add.ress", refreshInterval=20] {
Thing zone MainZone "Main Zone " @ "Wohnzimmer" [zone="Main_Zone", volumeDbMin=-81, volumeDbMax=12]
}
Note: After that 2 Things appeared in paperUi (or Habmin), so you can now look up all available items.
Added these 3items to my items file
Switch F1_LivingRoom_receiver_power "Receiver Wozi" (F1_LivingRoom) {channel="yamahareceiver:zone:wozi:MainZone:zone_channels#power"}
Switch F1_LivingRoom_receiver_mute "Receiver Wozi Mute" (F1_LivingRoom) {channel="yamahareceiver:zone:wozi:MainZone:zone_channels#mute"}
Dimmer F1_LivingRoom_receiver_volume "Receiver Wozi Lautstärke" (F1_LivingRoom) {channel="yamahareceiver:zone:wozi:MainZone:zone_channels#volume"}
Works like a charm now!
Thanks, Angelos, for you support.
