I feel like I must be missing something obvious here. Currently I run Hyperion on a Pi and then use WLED to directly drive the LEDs themselves (WS2812B's). It works mostly OK but the wifi lag on the ESP/WLED is annoying and I get occasional disconnects. Thinking of wiring the Pi in directly to the LEDs.
Currently i wire my ESP like I have in the attached picture. The main difference is I power the ESP board over the USB, so no 5v/ground from the power supply to the ESP board. Basically 3v, ground, and a data wire go from the ESP through a logic level shifter (low side for the ESP, high to the power supply) to the LEDs. The issue is when I unplug from the ESP and move the wires to the Pi (same thing, 3v, ground, and to GPIO 18) I get nothing. Can't even do a manual effect/control the LEDs that way. I've change the setting in Hyperion to "ws281x" for LED controller type, clicked save...nothing. Do I need to set something on the Pi for it to work? Install something?
