There are several open source DMX lighting consoles for desktop, this one seems particularly nice and with fresh controlling paradigm ideas.
The device definitions come as GDTF files, see the spec and other projects that utilize GDTF here [1]

I don't know much about BlindersKitten but the page says it can receive OSC. OSC was originally for sound applications but is common as a show control protocol today due to being fairly simple and open (much like MIDI-SC, a formerly common show control protocol based on MIDI). So conceptually OSC is likely how a show control system would send commands (cues) to BlindersKitten.
