TUL

EIB/KNX bus connector unit (TUL)

I am really happy and excited to have been involved by busware.de in the development of this very tiny but very powerful EIB bus connector unit (TUL). The TUL allows a connected PC to communicate with the EIB bus over USB. A powerful AVR microcontroller on the TUL allow developer to design their own dreams. Using the microcontroller pins over a connector hardware designer will be able to develop own EIB actors. Also a rapid prototyping is easily possible.

Firmware

At the moment a transparent tpuart firmware (standard LUFA) is available, which enbles the usage of the TUL as a TPUART modem. This firmware allows TUL to be used by EIBD and natively by FHEM (see below).

It is intended to develop a new firmware with FT12 protocol support. This will allow in full ETS compatibility.

Software Integration

TUL support is currently integrated in FHEM (an open source home automation software).
