Control your Denon AVR receiver with Homey locally via LAN.

This apps connects your Denon receiver with Homey via TelNet. The underlying technology is also shared with Marantz receivers so those may also work. Please make sure the receiver has a static IP address and has Network Control set to Always-On in its settings.

Features

Action Flow Cards:

• Turn your Denon AVR on and off, or toggle
• Absolute and relative volume controls (using percentages or dB values)
• Muting controls
• Set the input source. Sources are dynamically requested from the receiver including user defined source names - PS5 instead of GAME for example.
• Send customized commands. Add functionality that the app does not support by default: setting surround mode or tweaking parameters for example.

When Flow Cards:

• Turned on/off
• Volume changed
• Source changed (in general or to a specific source)

Condition Flow Cards:

• Is the receiver powered on?
• Is the receiver set to a specific input source?

About Custom Commands

Custom commands allow you to specify custom data to send to your Denon device. These are generally uppercase short words like: MVUP, MVDOWN, SIDVD or Z2ON. You can look up commands that your device supports by doing a websearch for 'denon telnet protocol' including your model number. There are several excel sheets and PDFs with available commands and a lot of them are shared between models. Note that the Denon AVR app will automatically terminate your commands with the required ''.

Supported Devices

Most Denon models that are network control enabled through Telnet should work. Some Marantz receivers have also been reported to work with this app.

Please let me know if your Denon model is supported.

Currently unsupported

• Zone2 and Zone3 control are currently only possible by using custom commands.
• This app uses telnet to communicate with the receiver on port 80, not the web interface via port 8080.

Future Things

Most important features are implemented but there are some things that would be nice to have. If there is some demand for it these might be implemented until then the base functionality remains as is.

• Zone2 control; channel select and volume.
• More trigger cards. (on/off trigger card is available)
• More mobile controls; channel select.

Version 1.4.0

• Sources list now populated by receiver including user defined names (like PS5 instead of GAME).
• Added PHONO and GAME1 to the default sources list.
• Faster response handling.
• Improved general hint and messages.
• Deprecated old obsolete cards.

Version 1.3.x

• Added source change trigger cards.
• Fixed changed settings not applying until restart.
• Fixed condition AND card not working properly with multiline responses.
• Improved stability with regards to message handling.
• Added CD to source list.
• Added support e-mail and bug webpage.
• Fixed the volume slider and relative volume(%) card.
• Updated card texts to match Homey's built in descriptions and updated Dutch translations to be more clear and match language used in Denon's manuals.
• Added (obsolete card) text to duplicate cards that will get removed in the future.
• Added fail-safe to avoid app getting unresponsive.

Version 1.2.1

• Fixed an issue where adding a new device would fail.

Version 1.2.0

• Upgrade to Homey SDK3.

Version 1.1.6

• Deleted devices are handled correctly. All running tasks are killed and callbacks cleared. Before deleted devices would linger due to status and command timeouts.
• Added titleFormatted to flow cards: Selected As Source, Adjust Volume, Set Volume and Select Source. For increased readability.

Version 1.1.5

• Volume clamping added (both in app.json and ensuring it in device.js).
• 'new Buffer' replaced with 'Buffer.alloc', due to deprecation.
• Moved source asset files into .src to exclude it from builds.
• Added brandColor, dark gray fitting Denon's overall look.

Version 1.1.4

• Fixed crash when receiving an error when trying to use the muting capability.

Version 1.1.3

• Fixed an issue where the volume action card could cause a crash if it received a 'dual line message' from the receiver.

Version 1.1.2

• Fixed an issue where a volume response message from MV? could be discarded erroneously. Leaving the socket open and resulting in a confusing or possibly even broken series of events.
• Command messages are given a number which makes it easier to follow the flow of events in the log file.
• Changelogs removed from README.TXT per Athom request.

Version 1.1.0

• Mobile control for volume setting and muting (volume_set, volume_up, volume_down, volume_mute capabilities added).
• Polling feature added; will automatically detect changes to power, muting and volume.

Version 1.0.0

• Updated icon to be centered properly in app.
• Readability of advanced settings improved.
• Reduced time before a receiver is considered unreachable. Reducing the time before a proper error shows.
• Bumped version number to be semantically compatible with Athom's conventions.

Version 0.2.1

• Power toggling could cause the socket not getting closed when the receiver returns an error message, blocking any new requests to the receiver.

Version 0.2.0

• Custom command flow card added. Send your own data to your Denon device.
• Converted to Homey SDK 2. Promises used where applicable.
• Flow cards now show errors; failed to send, IP not found, etc.
• Device specific settings are stored and not requested during each command request.
• Command processing loop now stops when the command buffer is empty.

Version 0.1.9

• Organized and cleaned up some code.
• Value label for volume cards is now 'dB' instead of 'db'.
• Updated compatibility list and some text in README.
• Fixed JPEGs for the Athom app store having a white background of 253 instead of 255.

Version 0.1.8

• Added mobile card for onoff, other capabilities such as volume are for a future release.

Version 0.1.7

• Added option to use ZM instead of PW to only control the Main Zone. Zone2 would also get turned on/off on devices with multiple zones, single zone devices should use PW.
• Added more AUX channels for 3100-W and N8: AUX2, AUXA, AUXB, AUXC and AUXD.

Version 0.1.6

• Fixed crash in capabilities.onoff.set.
• Power flow cards now use module.exports.capabilities, removing duplicate code and making the onoff state data available for insights.

Version 0.1.5

• A change in Homey meant device status could be requested before settings were saved when pairing. Failsafe added.

Version 0.1.4

• Fix for volume adjust not parsing whole dB numbers correctly which could cause large jumps in dB.
• Fix for volume adjust sending negative dB values, which is ignored by the AVR but makes no sense to let happen.
• Reponse packet telling that the AVR is on max volume is not considered a real volume request response. (Caused no problems but still a bug.)

Version 0.1.3

• Fix 'substring' of null crash for channel condition flow card.
