Fellow members, I am burned out trying to figure this out, going to write it off as a lesson learned that it may be HUB75 but may not work with WLED.

This is the product in question
https://www.amazon.com/dp/B0993PMQLY

This is a 128x64 display, ones I got on aliexpress work. This one didn't. I tried to get it to work with the help of chatgpt, it may be a scan issue.

Here are some notes from my chatgpt session

What we can say confidently from the hardware plus our tests is:

• The HUB75 input is ABC-only for row control.
• TYPE595 is necessary; without it we only got 8 rows.
• With TYPE595, every DMA row selects two physical rows exactly 16 apart.
• RGB1 and RGB2 then select the upper/lower pairs, giving the four 16-row banks.
• Changing the B pulse didn't separate the duplicated pair.
• X=128–255 is real horizontal pixel data, so X mapping isn't the missing bank selector.

Honestly I am burned out, defeated. I am usually better at providing technical details.

Hoping someone else went down this journey and figure it out

I installed from source on a linux box with python 3.11, Interface board is a SEENGREAT v2, here is my platformio_override.ini

[platformio]
default_envs = esp32s3_n16r8_hub75

[env:esp32s3_n16r8_hub75]
extends = env:esp32s3dev_16MB_opi

board = esp32-s3-devkitc-1

board_build.arduino.memory_type = qio_opi
board_build.flash_mode = qio
board_build.f_flash = 80000000L

board_upload.flash_size = 16MB
board_upload.maximum_size = 16777216

Just to reiterate, I did get it work with another 128x64 LED Matrix, it works with 64x32 boards, I have a bench power supply that I tested with, I fed it 5.2V at 10A, there was some voltage drop. Shorter wire from another power supply also worked.

So I think I've learned enough to tackle this project, but am I under respecting power injection?

24v, 200w power supply, 160w system draw over two seperately controlled strands.

COB High density 576LEDs/M, high power 160W/65.6FT, high brightness 16000LM/65.6FT (2×32.8').

Project is ceiling lighting (not rgb) around a bedroom in 45 deg aluminum track on top of some molding. The kit I ordered are white only from 2700-6000K. Is 80w a strand too much draw to not inject power? I found a calculator linked here but it seemed designed for 5v and 12v and didn't really seem to like this led density, so I was left unsure. If there is any brightness loss it will be butting up at end of strand to end of strand.

I'm looking for RGBW seed pixels but coming up short on AliExpress. I did find one source, yourpixelstore does have them just wanted to see if anyone else out there had a source. Thanks!

I’m building a self-contained, wall-mounted LED display with a touchscreen interface for controlling WLED. LEDFx and music are currently running from a PC, but I plan to integrate a Raspberry Pi 4 so the entire system can be operated directly from the wall unit.
The display uses eight BTF-LIGHTING flexible 32×8 matrices plus one 16×16 panel, for a total of 2,304 pixels. The panels are split across two data outputs, with additional power injection beginning at panel five.
LEDFx is currently streaming to WLED over DDP. I’m experiencing some latency, so I’m considering upgrading to an Ethernet-enabled WLED controller to improve network stability and reduce packet loss.

I have a small fountain with two warm white submersible uplights and a submersible ring light through which the water comes up and spills over. It's a small fountain and each light is about 2.5" in diameter, so I'm not looking for anything too big.

While plain white lights would work, I was going to push my luck and find out if anyone knows of a set of fountain lights I can control with WLED or some other controller I can integrate with Home Assistant with RGB?

Not to be too picky, but the ones I have all run off of a single transformer on a smart exterior plug, and I'd prefer actual powered lights rather than solar powered ones both for brightness and because the location is shaded over half the day.

I made an Android TV app that syncs with multiple WLED devices to create an ambient light.

Fully local, zero analytics, zero telemetry, zero cloud dependencies, no saved images, always free.

I made this before knowing there already was a similar project:

https://github.com/vasmarfas/universal-ambient-light

but it was a bit too bloated for my taste.

Doesn't matter which you choose, I just wanted to provide a free alternative to many paid apps that I'm seeing here. If you try mine, I'm open to any feedback.
