FHEM with CUL

FHEM is a cool software utility with a web-based GUI that is used in conjunction with different hardware devices to control amongst others FS20 and HomeMatic devices.

CUL is a little USB stick that runs an opensource firmware. It can be used to control the above devices through the air.
