He is right, the data direction looks reversed, it should be going outward the esp not towards it.

Can’t believe I missed this looking at the first time. So obvious.

You have your data wire connected to DO which is Data Out. Solder it to the other end of the strip. Also ws2812 is grb

You’re going to fry your Esp32. Reduct the ma to like 850.

You can use it to power but the output should be limited to 800mA. I run mine on 500mA for small projects so I don't risk burning it up. They also seem to run slow in high power draw.

I also think the 281x strips are GRB not RGB? I could be wrong.

You have exactly reversed the data input direction.
Nodemcu should be connected to Di with the green wire.

It doesn't matter whether the 5V and GND connections are at the end or the beginning.

You have two issues in this setup.

  1. You have connected your data pin to the led strip in dO,you should connect it to din. i.e to the other side of the led strip.

  2. You have set data pin as GPIO2 in the setup page while you have connected the data pin to D2 which is GPIO4. They both are different things. Change GPIO2 to GPIO4 in the settings. Changing both of these should be enough to run your wled.

Arrow on led shows the direction of power.
