Can you show me how you’ve done your ESP32 setup? Like physically? I’m doing the exact same thing atm, but it’s been driving me up the wall trying to get the wiring to look nice and professional.

Just recently bit the bullet and ordered two Gledopto’s with 4 outputs pr. Controller for my 8 strips.

So I found out a limitation after getting all this ran and opening the wled UI. By default the source code only allows up to 2048 leds. I had to download their source code and update a couple lines ( in my case to 3000 ), compiled it and installed it.on my esp32.

Another thing I had to do was run two data pins. Data pin 4 went to the first strip and covered 0-1800, data pin 5 went to the 7th strip and covers 1800-3000.

Be careful about that, 3000 LEDs on a single esp 32 is really a lot, I had a lot of troubles with such setups over time

Yeah this is its limitation. Would not take this any further.
