SleekXMPP python tools for running on devices. Python is perfect for easy programming of smart devices most of medium and high range devises is equipped with python from the start. like Intel Edison, raspberry Pi, Cubieboard, beagelbone and alike.
The code is currently in a branch on github to incorporate your local IO device you create field’s that can be readable or writeable and you start a GPIO python file r on your device and it is accessable as a device on the xmpp network.
