Trying to figure out if I have things setup wrong, or if this is something else. I’m setting up a project that will be controlled with a standard wall switch, so flip the switch and power goes to a meanwell RS-15-5 which is providing power to both the D1 mini and the LEDs. Not using any level shifters, the distance to the LEDs is inches. I do have a 1000uF cap across the power and ground. Using RGBW leds.
When I flip the power on I either get the first LED blinking a green/yellow color, or the entire string blinking full white. Seems random on which one happens. I have nothing happening at boot, meaning no save states being called, no macros, setting to turn LEDs on at boot is not enabled. However changing any of these does not change the behavior.
I have tried a trick I’ve used on other non WLED projects where I put an extra LED in between the controller and the rest of the strip, where that pixel is fed by a diode that drops the voltage to that single LED. It’s a super hacky way to get around some LED strips and controllers not playing nice at the voltage differential. I don’t have level shifters on hand to try them.
Does this sound like a hardware issue, something about how I have it wired? Or is this a WLED issue? I have noticed this on other projects, however only with the first LED blinking, not the whole string.
Edit, Figured out the randomly changing what blinks thing. It depends what what set when everything gets turned off. When the whole string was lit, the string then blinks quickly to that same state when power comes on and then WLED seems to catch up and turn them off. When the string was off before power is removed it is simply the first LED that blinks that yellow/green quickly.
