eBus coupler USB: eBus to USB data interface for PC, Raspberry Pi and Co


  • With the eBus coupler you can access the eBUS e.g. of your heating system in read and write mode.
  • With appropriate software, you can evaluate data from your heating system and send new values to your heating control system via the eBUS.


  • The ESERA eBus coupler is equipped with a galvanic isolation between eBus and PC interface.
  • The eBus input is bipolar, so you do not need to pay attention to the polarity of the eBus when connecting.
  • The housing of the eBus coupler is designed for control cabinet installation.
  • As data interface to your PC, the eBUS coupler is equipped with a USB interface of the manufacturer FTDI. Drivers for Windows, Linux and other operating systems are available via the FTDI site.

Note: The eBus coupler is not supported by Vaillant vrDIALOG Software.

A very good example (VWMon by Alexey Ozerov) for reading out eBus data can be found here or the project Fhem here
