Raspberry PI: EIB/KNX IP Gateway and Router

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 useĀ 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
