If you have something else using the IP controller for your Denon AVR 3808CI, such as your URC controller, it will not work! There is either a bug or security issue with some models where only one device could be controlling the IP functionality.
If True all sources are displayed in sources list even if they are marked as deleted in the receiver. If False deleted sources are not displayed. Some receivers have a bug that marks all sources as deleted in the interface. In this case, this option could help.
Specifies if zone 3 should be activated. Zones are displayed as additional media players with the same functionality as the Main Zone of the device supports. Some receivers do not support a second zone.
Specifies if a telnet connection should be used to receive device status updates. Using telnet provides realtime updates (local push) for many values but each receiver is limited to a single connection. If you enable this setting, no other connection to your device can be made via telnet. This will be set to true for new installations of the integration but false for existing installs to prevent compatibility issues.
Denon AVR receivers support a simple text-based network interface for sending commands to the receiver over the network. You can access this interface via the denonavr.get_command service. In addition, IR remote codes can also be sent to this interface.
So for example, the above command /goform/formiPhoneAppDirect.xml?VSMONI2 will switch the HDMI to output 2 (if your receiver supports it). Sending an IR code works the same, so the command /goform/formiPhoneAppDirect.xml?RCKSK0410370 will toggle muting.
The denonavr platform supports the standard media player controls such as turn_on and volume_up. Thus calling the service media_player.turn_on is equivalent to calling denonavr.get_command with the command /goform/formiPhoneAppDirect.xml?PWON. See media_player for more details.
