Did you find a solution to this? I’ve just hit the exact same issue.
I’ve written my own python script that is sending adalight packets over serial to an esp8266 (connected to a pi with gnd/rx/tx).
It works for a short while (10s seems about right, though sometimes it does randomly work longer) and then it seems to just reset back to the initial colours. I also notice that the last led seems to always be a white colour rather than the colour it should be, regardless of the number of LEDs bring used (I’m well within current requirements as have usbc powering the esp with 3a, and only running this on a handful of LEDs at this point)
