I found this cool python script from miracle2k to control a onkyo receiver in the shell.
Install the onkyo package…
sudo apt-get install python-dev
sudo easy_install onkyo-eiscp
onkyo --discover
TX-NR626 192.168.1.234:60128
now we can control the receiver by “onkyo command”
onkyo PWR00 //sets System Standby
onkyo PWR01 //sets System On
onkyo MVLUP //sets Volume Level Up
onkyo MVLDOWN //sets Volume Level Down
onkyo SLI01 //sets Input to Sat/TV
onkyo SLI10 //sets Input to BD/DVD
onkyo SLI2B //sets Input to NET
...
supportet devices and more ISCP-commands
Pimatic Onkyo ShellSwitch
{
"id": "onkyopower",
"name": "OnkyoPower",
"class": "ShellSwitch",
"onCommand": "onkyo PWR01",
"offCommand": "onkyo PWR00"
},
create some Onkyo Buttons in the config…
{
"id": "onkyo-buttons",
"name": "Onkyo Buttons",
"class": "ButtonsDevice",
"buttons": [
{
"id": "sat_button",
"text": "SAT"
},
{
"id": "ps3_button",
"text": "PS3"
},
{
"id": "net_button",
"text": "NET"
},
{
"id": "vol_up_button",
"text": "lauter"
},
{
"id": "vol_down_button",
"text": "leiser"
}
]
},
and some rules…
"if sat_button pressed then execute \"onkyo SLI01\" and set $onkyo_status = \"SAT\""
"if ps3_button pressed then execute \"onkyo SLI10\" and set $onkyo_status = \"PS3\""
"if net_button pressed then execute \"onkyo SLI2B\" and set $onkyo_status = \"NET\""
"if vol_up_button is pressed then execute \"onkyo MVLUP\""
"if vol_down_button pressed then execute \"onkyo MVLDOWN\""
"if SAT_Wohnzimmer is present for 10 seconds then turn on OnkyoPower and after 5 seconds execute \"onkyo MVL28\" and set $onkyo_status = \"SAT\" and after 8 seconds execute \"onkyo SLI01\"
I have an Onkyo NR626, which supports ZONE2. Just playng around and all works fine. With a PIR and a simple rule, the 
will follow me to the kitchen.
pimatic makes it possible
