Homebridge GPIO WiringPi - Platform Plugin
WORK IN PROGRESS
Please report issues at https://github.com/rsg98/homebridge-gpio-wpi2/issues
Supports triggering General Purpose Input Output (GPIO) pins on the Raspberry Pi.
Uses wiringPi as a back end to give non-root access to GPIO.
Requirements
- Homebridge - HomeKit support for the impatient
- node-wiring-pi - Node.js bindings to wiringPi
This version of the plugin expects WiringPi itself to already be installed - see the documentation for node-wiring-pi for more details, or just follow the instructions below for Raspbian.
Installation
-
Install the wiringpi package using
sudo apt-get install wiringpi
-
Install Homebridge using
sudo npm install -g homebridge
-
Install this plugin
sudo npm install homebridge-gpio-wpi2
-
Update your configuration file - see
config-platform-sample.json
in this repo -
Make sure your
homebridge
user is in thegpio
group.
$ sudo usermod -G gpio homebridge
Configuration
The pin numbers used in this config file are the BCM pin numbers, not the physical pins or WiringPi pin numbers.
You can run gpio readall
to generate a table showing how the BCM pin numbers map to the physical pins, which varies between models of Raspberry Pi.

Platform Config Items
Config Item | Valid Values | Description |
---|---|---|
platform |
WiringPiPlatform |
Must be set to this value to initialise this plugin |
name |
string |
What you want this platform to be called (appears in the logs and such like) |
overrideCache |
true / false |
Homebridge will cache all your accessories - setting this to true will ignore the cached value (direction, mode, etc.) and read them direcly from your config file |
autoExport |
true / false |
As long as your homebridge user has permission (i.e. is a member of the gpio group), setting this to true will automatically export the pins via sysfs, meaning you don't need a set-gpio.sh script |
Pin Config Items
Config Item | Valid Values | Description |
---|---|---|
"type" | "string" | Type of device connected to GPIO. Set to "Switch" for "out" pin mode, or one of "ContactSensor", "LeakSensor", "MotionSensor", "OccupancySensor", or "SmokeSensor" for "in" pin mode |
name |
string |
Initial display name for the PIN accessory - can be renamed in HomeKit app (e.g. Home) |
pin |
number |
The BCM pin number - see Pin Configuration below |
enabled |
true / false |
Whether you want the module to publish this pin as an accessory |
mode |
out / in |
Mode the pin should operate in |
pull |
up / down / off |
Configuration for the built in Pi pull up resistor |
inverted |
true / false |
Reverse the behaviour of the GPIO pin (0 is on, 1 is off) |
duration |
number |
Pin will turn off after this number of miliseconds |
polling |
true / false |
Whether Homebridge should periodically check the status of the pin (perhaps it's being set by something external to homebridge) |
Pin Configuration
If you don't use the autoExport
option above, you'll need to manually configure the relevant GPIO pins using the gpio utility included with wiringPi.
This is not necessary if you use autoExport and your homebridge user is a member of the gpio
group.

The pin number specified in the config.json file is the BCM pin number in this table.
To set up the pins correctly, this module includes a make-gpio-script
script, which will generate a set-gpio.sh
. You should run set-gpio.sh
before starting Homebridge so that all the pins are configured. If you start Homebridge using systemd, you can add set-gpio.sh
as a ExecStartPre command in the homebridge.service
file
$ node make-gpio-script config.json set-gpio.sh
The gpio tool is setuid root, so this script should be run as the user that runs Homebridge.
Troubleshooting
Homebridge reports no errors, but nothing is switched on or off
Check the permissions in /sys/class/gpio/gpioXX - autoExport
option should have created all these properly, if your Homebridge user account has the right permissions (i.e. is a member of the gpio
group)
$ sudo usermod -G gpio homebridge
If you are not using autoExport
, you should run the set-gpio.sh
script as the homebridge user (see section above to generate this script):
$ node make-gpio-script config.json set-gpio.sh
