I don't own an open DMX device yet, so I haven't written a controller for it.
You are absolutely welcome to fork this project, write a new controller that works with open DMX and then PR it :)

👋 Sorry for such a late reply to this, but I finally got my hands on an FTDI chip and have now implemented an OpenDMX FTDI controller -- this is currently in master, and will be part of the eventual 2.0.0 release.
