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
![node-red-denon-flow] (https://raw.githubusercontent.com/estbeetoo/node-red-contrib-denon/master/example.png)
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.
