Help with RGBWW LED Strip (WS2805) and Home Assistant – Warm White not working

Configuration
1

Hi everyone,

I’m using a GLEDOPTO controller based on an ESP32, running WLED version 0.15.

Home Assistant is running the latest version available as of today.

My setup includes a 5-meter WS2805 RGBWW LED strip.

It has 4 wires: V+, Ground, Data, and a fourth blue wire.

I connected both the Ground and the blue wire to the GND pin on the controller.

Everything works perfectly via the WLED web interface – I can control effects and colors smoothly.

However, in Home Assistant, I can only control the RGB part. When I try to set a color temperature or use warm white, the output is still RGB-based – no proper warm white.

Does anyone know how to correctly configure WLED and Home Assistant so that true warm white (WW) is used instead of simulated RGB color?

Thanks in advance!

The blue wire is another data line. Don’t connect it to ground, connect it to the other data line. It’s a backup in case one of the data lines is messed up.

Does warm white work in WLED? If so, then make sure you don’t have any funky settings in WLED:

Lastly, you can delte and re-add the device in Home Assistant. If the config is wrong, Home Assistant won’t have the color temperature part.

Also, my color screen has a separate control for color and white luminance separate from the global one the strip uses:

The UI here is totally broken for me, but you can use light.turn_on with RGBW controls to make it work outside of the UI.
