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

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

for anyone that might stumble upon:
I happened to have some cheap knockoff of the esp32c6-devkitc, that seems to be based on https://github.com/wuxx/nanoESP32-C6/blob/master/hardware/nanoESP32C6.pdf

However, the R4 resistor, that was supposed to be 10kOhm, was in my case shorted to 5V, causing no data going through. that means no LED was working, no matter what I tried.

Replacing it with a proper 10k resistor did solve the problem, attached picture for anyone that would like to fix it themselves.

It's finicky to get it right, as I had 0604 components, but you can fit them if you try hard enough :)
