Fastled addressable monochrome light

ESPHome
1

Hi All,
I am hoping for some advice on setting up a White only WS2811 addressable light in ESPHome. I have a partially working config at the moment, but HA treats the light as an RGB one. See below.

I have tried adding in color_mode: WHITE or color_mode: BRIGHTNESS but editor reports these are not compatible with fastled.
platform: monochromatic does not seem to support addressable lights.

In developer info the light shows as supported_color_modes: rgb even though it is only single colour.

light:
  - platform: fastled_clockless
    chipset: WS2811
    pin: GPIO19
    num_leds: 38
    name: "Headboard Light"
    id: fl_hb_light
    restore_mode: ALWAYS_OFF
    effects:
      - random:
      - addressable_scan:
      - addressable_twinkle:

  - platform: partition
    name: "${upper_devicename} Left Light"
    id: fl_hb_light_left
    restore_mode: ALWAYS_OFF
    segments:
      # Use first LED from the light with ID light1
      - id: fl_hb_light
        from: 0
        to: 17
  - platform: partition
    name: "${upper_devicename} Right Light"
    id: fl_hb_light_right
    restore_mode: ALWAYS_OFF
    segments:
      # Use first LED from the light with ID light1
      - id: fl_hb_light
        from: 18
        to: 37

Hello.
I know it took a lot of time, but did you manage to solve it? I want to do the same.
