 The `denonavr` platform allows you to control a [Denon Network Receivers](http://www.denon.co.uk/chg/product/compactsystems/networkmusicsystems/ceolpiccolo) from Home Assistant. It might be that your device is supported by the [Denon] platform.

 Configuration variables:
 
-- **host** (*Optional*): IP address of the device. Example: 192.168.1.32. If not set, auto discovery is used.
-- **name** (*Optional*): Name of the device. If not set, friendlyName of receiver is used.
-- **show_all_sources** (*Optional*): 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 (default). Some receivers have a bug that marks all sources as deleted in the interface. In this case this option could help.

 A few notes:
 
-- Additional option the control Denon AVR receivers with a builtin web server is using the HTTP interface with denonavr platform.
-- denonavr platform supports some additional functionalities like album covers, custom input source names and auto discovery.
-- Marantz receivers seem to a have quite similar interface. Thus if you own one, give it a try.

+- Sound mode: The command to set a specific sound mode is different from the value of the current sound mode reported by the receiver (sound_mode_raw). There is a key-value structure (sound_mode_dict) that matches the raw sound mode to one of the possible commands to set a sound mode (for instance {'MUSIC':['PLII MUSIC']}. If you get a "Not able to match sound mode" warning, please open an issue on the [denonavr library](https://github.com/scarface-4711/denonavr), stating which raw sound mode could not be matched so it can be added to the matching dictionary. You can find the current raw sound mode under "Development Tools/States" in the front panel.
