how to power off/on onkyo/integra receivers automatically - swinokur - 01-20-2022

Hi,
I've just started using Moode and in the process of setting it up and getting it going I've done a few things that I thought I'd share.

In my place I've got a Rpi4 connected to my Integra AVR over HDMI. I wanted the AVR to turn on, change to the proper input and set the volume when Moode started playing audio. I also wanted it to turn off after nothing had been playing for a bit.

Here's how I did it:

- installed onkyo-eiscp (github for that project is here: https://github.com/miracle2k/onkyo-eiscp)

Code:
$ sudo pip3 install onkyo-eiscp

- then I made sure it was working. My Integra AVR is an older unit so it isn't auto-discoverable by eiscp

Code:
$ onkyo --discover

(returns nothing, not a shock.)

- But I know the IP address I've given the AVR so these work

Code:
$ onkyo --host 192.168.0.125 power=on

unknown-model: system-power = on

$ onkyo --host 192.168.0.125 source=query

unknown-model: input-selector = video2,cbl,sat

I found here on the forum that someone had written a bit of python to control relays when moode started / stopped playing - so I adapted that script. Thanks to the person who wrote that one! (original script was here: https://gist.github.com/michaelfdeberry/d3e7c9b4c4e1305be863d81a7e09f3de)

Code:
#!/usr/bin/env python3

import os

import time

import eiscp.script

defaultDelay = 5 #seconds 

playbackDelay = 300 #seconds 

currentState = False # the current state

def isRunning():

    return "RUNNING" in os.popen('cat /proc/asound/card0/pcm*/sub*/status | grep RUNNING').read().split()

while True:

    if isRunning() and not currentState:         

        receiver = eiscp.eISCP('192.168.0.125') # 125 = integra

        receiver.command('power on')

        receiver.command('volume=40')

        receiver.command('input-selector=video2')

        receiver.disconnect()

        currentState = True

        print("onkyo Activated")

        time.sleep(defaultDelay)

    elif not isRunning() and currentState:   

        # delay again on playback stops to account for track changes

        #time.sleep(defaultDelay)

        # we wait longer to shut down, in case there's a device swap or whatever 

        time.sleep(playbackDelay)

        if isRunning():

            # if it's running don't deactivate the realay   

            print("Playback resumed, cancelling deactivation")

            continue

        else:

            # deactivate the relay

            receiver = eiscp.eISCP('192.168.0.125') # 125 = integra

            receiver.command('power off')

            receiver.disconnect()

            currentState = False

            print("Onkyo Deactivated")                                     

        time.sleep(defaultDelay)

    else:

        print("No State Change...")

        time.sleep(defaultDelay)

This worked fine from the command line, so I then added it as a system service, as the relay controller did:

- Save the contents of onkyotoggle.service script to /lib/systemd/system/onkyotoggle.service

Code:
[Unit]

Description=MoOde Onkyo Toggle Daemon

[Service]

Restart=on-failure

WorkingDirectory=/home/pi

ExecStart=python3 onkyotoggle.py

ExecReload=/bin/kill -HUP $MAINPID

KillSignal=SIGINT

[Install]

WantedBy=multi-user.target

(this is also in the attached zip file)

- set it going in systemd

Code:
$ sudo systemctl enable onkyotoggle

Created symlink /etc/systemd/system/multi-user.target.wants/onkyotoggle.service → /lib/systemd/system/onkyotoggle.service.

$ sudo service onkyotoggle start
