denon-avr

A handy node library which allows you to control and receive events of a Denon AVR.

Few words

This library is not complete. There are functions missing. Feel free to contribute by doing pull requests. New functions are easy to implement.

Get the protocol specification here: http://assets.denon.com/documentmaster/de/avr3313ci_protocol_v02.pdf

The protocol is pretty unified so any Denon AVR should be somewhat compatible.

A yuidoc based documentation is available here: http://lmoe.github.io/node-denon-client

Introduction

This library is designed to provide a simple way to operate with a Denon AVR. Making it an easy use in your own IoT project, or any lazy remote after your remote went missing.

It's using ES6 functionality and is based on promises. You are still able to receive events though.

Make sure to use strict and a newer version of node. I haven't tested it with a lower version than 5.10.1 yet.

Examples

Setting up is simple.

// Initialization
const Denon = require('denon-client');
/**
 * Denon is now an object containing DenonClient and Options.
 * Use the DenonClient to send requests. Use the Options to define the data.
 */
const denonClient = new Denon.DenonClient(`${DenonAVRHost}`);

// Subscribe to any available event
denonClient.on('masterVolumeChanged', (volume) => {
  // This event will fire every time when the volume changes.
  // Including non requested volume changes (Using a remote, using the volume wheel on the device).

  console.log(`Volume changed to: ${volume}`);
});

// Connecting
denonClient
  .connect()
  .then(() => {
    // Tasty promise chains..
    //
    // You are free to send any command now.

    return denonClient.setInput(Denon.Options.InputOptions.Aux1);
  })
  .then(() => {

    return denonClient.setSurround(Denon.Options.SurroundOptions.Stereo);
  })
  .then(() => {

    return denonClient.setVolume(98); // Destroy neighborhood
  })
  .catch((error) => {
    // Oh noez.
    console.error(error);
  });

Changelog

1.0.6

• Fix setVolume returns no promise
• Fix setVolume does not set float values like 22.5 as the denon API requires a non float number (225)

1.0.5

• Fix the getVolume functionality as it returned a three digit value when the receiver returns a double (22.5 -> 225)
• Implemented transform methods for each event / hook
