Hi,
How about a proper documentation about the LED integration?
Thanks :-)

I made a quick analyse and here is what I found (I might be wrong, I am not the author):

LED is implemented by a function LED that write to /tmp/lastled
https://github.com/tholum/PiBunny/blob/503ba8407f851c1b2f1edec7357a1c604921b2b7/bin/LED

And inside pibunny.js the content of /tmp/lastled is readed when change is detected.
Finally, it exec ("neouart " + HEXCODE) to set the LED color.

neouart is coming from here:
https://github.com/bigjosh/NeoUart

It drive a single WS2812B NeoPixel NeoUart and here is the wiring schematics:
