All in all, I have to say, #Grobpfottaster2Light worked way better than feared.
The batteries held up flawlessly, the button response time was very quick, no electronics pack died during the event, the wireless link was stable, the DMX worked also over longer cables and most importantly: people had fun :3
The wireless range was also surprisingly good. It only got spotty at around 2/3 of the tram length away from the receiver (depending on the amount of creatures inbetween).
And for having the idea on Sunday, developing the the code from Tue-Thu and building all of the hardware on Friday, the result was really nice :3
Thanks for reading ^w^
Here, have a bonus video of the almost finished system at 3am on the night before the event as a treat:
