node-red-contrib-denon

A Node-RED node to communicate Denon AVR receivers over telnet (port 23) TCP/IP connection.

Install

Run command on Node-RED installation directory

npm install node-red-contrib-denon

Usage

If you want to use this node simply inject message's payload as string:

Denon-Out node sends commands to Denon devices

Commands with no arguments

Master Volume

MV20

Master Volume set to 20 - command from Denon AVR protocol: DENON_PROTOCOL_V7.6.0.pdf

Master Volume Up

MVUP

Master Volume UP by 0.5 - command from Denon AVR protocol: DENON_PROTOCOL_V7.6.0.pdf

Master Volume Down

MVDOWN

Master Volume DOWN by 0.5 - command from Denon AVR protocol: DENON_PROTOCOL_V7.6.0.pdf

Commands with arguments

Currently, there is only one such command implemented: SetVolumeDB. One may use setvolumedb too, cause it's case insensitive. So, msg object shoud looks like:

{
    topic; "setvolumedb",
    payload: -65.5
}

It will set the master volume to -65.5dB.

Denon-In

Node sends to single output messages from Denon quipment with structure:

{
    topic: 'denon',
    payload: 'PWON'
}

where notification could be PWON and data contain additional info, arguments for current notification.

Collect debug log for issues

Current package use debug package: https://www.npmjs.com/package/debug. Run you node-red with command to enable debug output:

set DEBUG=node-red-contrib-denon
node-red

for globally installed Node-RED, or

set DEBUG=node-red-contrib-denon
node node-red/red.js

for local Node-RED. Highly recommend to use (cross-env)[https://www.npmjs.com/package/cross-env] package to set enviromnent variables in cross OS way.
