Thank you for sharing the details.
I'm using this device https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32c6/esp32-c6-devkitc-1/user_guide_v1.1.html
It says it also works with GPIO8:

Unfortunately this code does not work. I tried your versions of ESP-IDF and Platform, and the latest 5.3.1 and 6.9.0 - no success 😞

Got this working on my ESP32-c6-devkitc-1 revision v0.0 early sample boards. Note the rgb_order for me was rgb_order: GRB.

Thank you very much for providing this config.
I can confirm, this works on "Waveshare ESP32-C6-DEV-KIT-N8" board 🎉

Does not work in my setup with any version.

  This feature is not available for the IDF framework version 5.

@trianglesis The error message is unclear but it seems to be saying that "rmt_channel: 0" is not supported. Removing that fixes it for me.

That is interesting.
Does that give you control over the board's LED?

• power on\off
• color change

@trianglesis Yep! All works fine. Not the same board as yours, this is a knockoff of the Waveshare ESP-C6-Zero board but I'd be surprised if it was different.

I played with another similar device this weekend: https://www.waveshare.com/esp32-c6-lcd-1.47.htm

Like @midnightveil, I also had that rmt_channel error about IDF v5. LED works great with that line removed 👍

It worked just fine!

But colours are inverted:

light:
  - platform: esp32_rmt_led_strip
    name: Status LED
    pin: GPIO8
    rgb_order: GRB
    num_leds: 1
    chipset: ws2812
    web_server: 
      sorting_group_id: sorting_group_controls

Change the rgb_order to the correct order. Probably look at your data sheet for this.
