Hi,

this Post is a tutorial to build an IP EIB/KNX Gateway based on a Raspberry Pi completely from the scratch. The core components are the eib daemon from the bcusdk in conjunction with the TPUART EIB Bustranceiver module.

The Hardware

3 components are needed:

• A Raspberry PI
• A EIB Buscoupling Unit
• Adapter Board to connecting both

You can use A or the B Model of Raspberry Pi. The eibd daemon has minimal hardware requirements.

There are two possibilities for connecting a computer to the EIB/KNX Bus over a RS232 serial interface. Both are supported by eibd.

• Buscoupler 2 with FT12 protocol
• TPUART module
