WebIOPi is a fully integrated Internet of Things framework for the Raspberry Pi.

Control, debug, and use your Pi's GPIO locally or remotely, from a browser or any app.

WebIOPi is the perfect Swiss-knife to make connected things with the Raspberry Pi.

Developed and provided by Eric PTAK, french R&D engineer in networks, soft ware, and Internet of Things.

Javascript client library built on top of jQuery

Python client library with HTTP and CoAP support

What for ?

Use webiopi.GPIO library to control GPIO in your Python scripts

Use devices drivers to interact with DAC, ADC, sensors and more in your Python scripts

Use Serial, I2C and SPI webiopi classes in your Python scripts

Use the GPIO Header web-app to play with GPIO and debug circuits

Use the Serial Monitor web-app to debug Serial devices

Use the Devices Monitor web-app to debug devices like DAC, ADC, sensors and more

Create a web-app with the Javascript library to remote controls things connected on GPIO

Add webiopi in your existing Python script to simply add all WebIOPi features

Extends webiopi with your own macro

Extends webiopi with scripts loading facilities in a Arduino fashion way (setup, loop, destroy)

Use the Python Client to make Pi-2-Pi communication through the REST API

Use the Python Multicast Client to control multiple Pis with a single REST call

Use the Java Client to use the REST API from a Java application, including Android

Use the REST API from any technology/language
