A python app to monitor a variety of GPIO pins and publish MQTT messages when the state changes
Latest commit 7fde9ff Jan 5, 2014 @kylegordon Remove debug line



This script will parse a list of pins to be monitored from /etc/mqtt-gpio-trigger/ and publish MQTT message whenever they change state. 
If it's run on a Raspberry Pi, you will need the WiringPi library from https://projects.drogon.net/raspberry-pi/wiringpi/ as the gpio command is used to export the pins to the sysfs interface.
