Raspberrypi GPIO Remote Control

Remote control appliances via WebInterface by using a RaspberryPi + Node.js + GPIO Relay control board (turning On/Off a coffee machine, toaster, heater, etc from a webpage in your mobile phone, tablet or laptop)

NPM dependencies

Raspberry Pi GPIO Remote control dependes on the following node.js packages:

• rpi-gpio https://github.com/JamesBarwell/rpi-gpio.js

• Flatiron

• Socket.io

• others - please check package.json

How to compile node.js on a RaspberryPi

How to get things running

Clone project and install Node.js necessary packages

git clone git://github.com/nneves/Raspberrypi_GPIO.git

cd Raspberrypi_GPIO

npm install

Raspberry Pi GPIO access requires sudo (for gpio access - still working on a safer solution)

sudo node app.js 8080

or (for quick testing)

npm start

Experimental testing with WebSockets protocol

sudo node app.js 8080 websockets

GoogleTalk (XMPP) integration
