ArduHA is an opensource Framework for Home Automation using arduino.
It is intended to retrieve data from sensors and send data to actuators in a standardised way.
ArduixPL is a set of Arduino libraries to implement xPL protocol in the ArduHA framework.
It is aimed to assemble Home Automation modules using Arduino's boards and xPL protocol.
switches, temperature, humidity sensors, light dimmer, level sensors, etc...
Many modules are fully implemented, but libraries should allow to create your own specific modules.
