KNX Gateway

Hello,

For school we need to make some sort of home automation project. We want to use Openremote to send KNX-commands and instead of using a KNX-gateway we want to use the Arduino ethernet. We have done some research and we find out that there are library’s like calimero ( http://calimerong.org/ ) that maybe could help us. and if we can read these commands we need to control stepping switches(teleruptors, impulse switches) of 12V.

Are there already projects like this ore something like this??
We can use all information.

Thank you.
