I would like to request a new E1.31 (sACN) input mode for WLED where one DMX channel controls one LED pixel, instead of the current RGB mapping (3 channels per pixel).
This would make WLED extremely useful as a DMX/sACN training, testing, and diagnostics tool.
Current behavior
WLED currently maps DMX data as:
- CH1 = Pixel1 Red
- CH2 = Pixel1 Green
- CH3 = Pixel1 Blue
- CH4 = Pixel2 Red
- etc.
A 32×16 matrix (512 pixels) therefore requires 1536 DMX channels / 3 universes.
Requested behavior
New input mode:
Channel Visualizer (1 Channel = 1 Pixel)
Example:
- CH1 → Pixel1
- CH2 → Pixel2
- CH3 → Pixel3
- …
- CH512 → Pixel512
This allows a 512-pixel matrix to be controlled with a single DMX universe.
Main use case
I am building a 32×16 WLED matrix (512 pixels) for DMX/sACN training. Using software such as sACNView, students could directly see which DMX channels are active without needing RGB addressing.
Example:
- Set CH237 = 1
- Pixel 237 lights up immediately.
This is much easier to understand when teaching:
- DMX channel numbering
- Universe structure
- Patching
- Channel allocation
- Signal testing
Proposed visualizer modes
1. Fixed Color (primary request)
User selects a color (e.g. purple).
DMX value controls brightness:
- 0 = off
- 1…255 = selected color with corresponding brightness
Optional On/Off mode:
- 0 = off
- 1…255 = full brightness selected color
2. Grayscale
3. Hue / Color Wheel
DMX value maps to hue.
4. Palette
DMX value indexes the currently selected WLED palette.
Suggested UI
DMX Input Mode
- RGB
- RGBW
- DRGB
- Channel Visualizer
Additional settings:
- Visualizer Mode: Intensity / On-Off / Hue / Palette
- Visualizer Color: color picker
- Start Channel: configurable
Why this would be useful
- DMX training classrooms
- sACN / Art-Net demonstrations
- Patch verification
- Channel activity monitoring
- Troubleshooting universes
- PLC / automation visualisation
- Sensor matrix displays
WLED is already excellent for LED control; this feature would also make it a very powerful DMX analysis and education tool.
Thank you very much for your great work, and thank you for considering this feature. I am convinced that it would be of great benefit, particularly for educational and diagnostic purposes, and could benefit many WLED users beyond my specific project.
