Yes. I did it myself, configurable duration. Three sets of parallel color values…
I’ve almost posted on Lemmy before, but the script is too long (the variable RGBs drive the length)… It is absolutely possible. Starts white, moves gold, peach, pink, red, then blue. Brightness subsides with time and sun’s position.
I use home assistant to make it happen. The software is free and an RPi4B+ doesn’t break most banks.
