I’m working on another WLED project and have run into an issue. I’ve got these https://www.aliexpress.us/item/3256802634297184.html?algo_pvid=87a4b355-4eb4-45a9-82aa-f135f5e54a20&algo_exp_id=87a4b355-4eb4-45a9-82aa-f135f5e54a20-0&pdp_ext_f={“sku_id”%3A"12000022340959301"}&pdp_npi=3%40dis!USD!57.0!54.15!!!!!%402122443916771759801585221d06cc!12000022340959301!sea!US!160132098&curPageLogUid=hPzglLGIuYOf

Triple row, ws2811 LED’s. I’m running WLED version 0.13.3. Powering ESP32 from USB port. LED strip powered by separate 12v source, and data pin hooked to D2.

Lights are flashing all sorts of random colors, not in any pattern, and are not responding to commands. Please help! Trying to build a fish tank light!

Did you connect the ground from the LEDs to the esp? All DC Grounds need to be common.

I knew it had to be user error! Thank you!!! That was it. I tied the ground from the LED strip to the GND pin next to the 3V3 pin on esp and now I’m rocking! Thanks again!!
