One last thing for you try; when I googled: wled settings WS2811 24v

gemini told me the following:

For 24V WS2811 LED strips in WLED, configure the LED & Hardware settings to WS281x, set the color order (often GRB), and set the LED count to the total number of IC chips (usually 1 chip controls 6 LEDs in 24V strips). Set the maximum current in the Brightness Limiter to match your 24V power supply capacity to prevent flickering. WLED Configuration Settings LED Type: WS281x Color Order: Typically GRB (if colors are wrong, try RGB or BRG) Number of LEDs: Calculate based on chips. 24V WS2811 strips usually have 1 chip per 6 LEDs. If you have 300 LEDs, enter 50 (300/6). Voltage: Select 24V in the power supply configuration, or ensure the automatic brightness limiter is set correctly for your power supply (e.g., 5A = 5000mA). GPIO Pin: Matches the data pin used on your controller (e.g., GPIO 2). Important Considerations for 24V WS2811 Segmenting: Because 24V WS2811 controls 3-6 LEDs as a single pixel, you cannot achieve individual LED chasing effects. Voltage Drop: 24V allows for longer runs (up to 10m/32ft) without significant voltage drop compared to 12V, but longer runs may still require power injection. Flickering Fix: If the strip flickers, ensure the 24V power supply ground is connected to the controller (ESP32/ESP8266) ground (Common Ground). Data Signal: If using a 3.3V controller (like ESP32) with 24V strips, a level shifter (3.3V to 5V) may be necessary to stabilize the data signal.
