Homebridge support for home theater devices using CEC over HDMI
homebridge-cec-accessory was written with Raspberry Pi in mind.
Create homebridge accessories for each CEC device you'd like to control.
Currently power and volume are the only available controls, and volume
only toggles mute (and probably only works with an attached receiver).
No automatic detection of attached devices is performed. For each device, create
an accessory entry in your config.json.
Bug reports, feature requests, and pull requests welcome.
-
Follow these instructions to install and run homebridge on Raspberry Pi. Don't give up. Hang in there.
-
Install cec-utils using package manager:
$ apt-get install cec-utils -
Install homebridge-platform-cec:
$ npm install -g homebridge-cec-accessory -
Open an issue if you run into problems.
Here is a sample of what you might put in your ~/.homebridge/config.json
"accessories": [
{
"accessory": "cec",
"name": "TV Power",
"type": "power",
"address": 0
},
{
"accessory": "cec",
"name": "Amp Volume",
"type": "volume",
"address": 5
}
]
"name" can be any string you want, but must be unique. Try to keep it short
and descriptive.
"type" must be either "power" or "volume".
"address" specifies the CEC destination address of the device, represented
as an integer. Here are the possible devices:
0: TV
1: Recording 1
2: Recording 2
3: Tuner 1
4: Playback 1
5: Audio system
6: Tuner 2
7: Tuner 3
8: Playback 2
9: Recording 3
10: Tuner 4
11: Playback 4
The best way I've found to find your devices is to use the cec-client tool
which comes as part of the cec-utils package.
From the command line:
$ cec-client -d 1
Once it outputs waiting for input, type scan and press return. This might
be slightly confusing, but the number to use for "address" is the value
presented as device #, not the decimal separated IP-style address.
Under the covers, homebridge-cec-accessory uses the cec-client to interface
with your HDMI device. Stopping and starting repeatedly can cause things to go
awry. If the plugin reports that cec-client never reported ready, try
restarting.
If you're having trouble doing something with this plugin, verify you can do it
with cec-client. If it can't, neither can we.
