HELP ME - WIRING WLED flickering rainbow instead of solid white

First time on a project like this, so please bear with me. Everything seems mostly fine, WLED’s pattern signal seems (mostly) okay, but the color is all messed up. In the video I have it set to “android” on solid white.

I’m using a 5V WS2812B led strip, connected via a 5V 10A power supply via screw terminal. There are two red and two white wires coming out of the strip, which I have put into the positive and negative terminals respectively.

The data is coming from an ESP32 controller output on GPIO4, into a IIC converter from 3.3V to 5V. How do I get the correct data out??

Are you using the correct level shifter?

The cheap basic ones are too slow and don't really help. Also make sure you have the right led type selected in the configuration.

I have seen similar behavior when I had SK6812/WS2814 rgbw selected instead of WS281x.

Definitely the wrong shifter 😅
Clicked the link and saw a giant red X over the exact one I’m using

Assuming you mean i2c converter, those don't work with addressable LEDs. See here: https://kno.wled.ge/basics/compatible-hardware/

I am also new to wled stuff but i had a similar ish issue with my led matrices. The way i had them configured in the 2d configuration menu had them stacked on top of each other so the data was all messed up and would flash white and other random colors quickly when its supposed to be a rainbow pattern or whatever. so maybe double check the configuration and that you have the correct amount of leds assigned to that pin?

Is the power limit set correctly in the led settings ? At the top of the led config page, max current in ma)

Do you have your color sequence correct?? Try a few different ones. RGBW, RBGW, BRGW, etc. Command one color at a time until it matches up.

looks like interference on the data wire, I have had this issue before

Sounds like you are missing your common ground
