@MDAR thanks for the detailed response!
I played around on QLC+ last night and successfully connected openHAB using sACN. Unless I’m missing something, it seems to now support numerous universes. I was able to control virtual dimmers and start scenes and chasers using openHAB items.
I’ll need to play around with it more once I’ve actually acquired some DMX gear, but it appears to be a great multi platform option. It has a built in RGB matrix tool, and I successfully created a test device of 1x200 pixels that would fit my use case for neopixel lights. It includes a number of chaser options.
I just so happen to have a spare lying around! Does this require a second router, or can you get away with just using static IPs and connecting the devices directly?
