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.
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
