onkyo-rpi

Command line tool to control ONKYO devices connected to Raspberry Pi via Remote Interactive protocol. This project was mainly inspired by a similiar project for the arduino plattform Onkyo-RI. Thanks to docbender for digging out the protocol description from the web. :)

Send message

The script main.py accepts a message as parameter from 0-4095 as hex or int (12 bits) which you want to send to your device.

Example:

# sends turn off message to device
python main.py 0x1AE
# you can additionally pass a gpio port as parameter
python main.py --gpio 25 0x1AE

Scan for supported messages

With the script scan.py can you find out which messages your device reacts to. You can parameterize the lower and upper boundaries of your scan, the gpio port to use and the delay between sent messages. Run the script and check your device for changes.

Example:

# scan from 0x000 to 0xFFF
python scan.py --gpio 25
# set boundaries
python scan.py --lower 0x120 --upper 0x12F
# increase delay in seconds between sent messages
python scan.py --delay 1

Known messages

I am using an Onkyo TX-SR500E AV Receiver and following messages lead to actions on the device.

Message	Action
0x070	switch to mode TAPE
0x07F	turn on and switch to mode TAPE
0x120	switch to mode DVD
0x12F	turn on and switch to mode DVD
0x1A0	switch to mode VIDEO2
0x1A2	volume up
0x1A3	volume down
0x1A4	mute
0x1A5	unmute
0x1AE	turn off device
0x1AF	turn on and switch to mode VIDEO2

Connection

The connection to the RI interface is a simple 3.5 mm mono headphone jack. Connect the tip of the jack to a GPIO output pin (default: 25) and the ground of the jack to a ground pin on your raspberry pi.
