LEDC Dimmer setbrightness resolution to big

I have a led strip that i would dim.
If i look at the dasboard of homeassistant the slider have a resolution off 255 setpoints.
in ESPhome i can only set 0-100% this resolution is to big for me.
The light strip is there to simulate a sunrise and sunset in a aquarium.

in between 38% and 39% there a 3 extra steps in HASS, why can’t i setbrightness like in HASS (from 0-255) ?

Need some advice in this

and my esp configuration:

  - platform: ledc
    pin: GPIO4
    id: pwm_output
  - platform: monochromatic
    output: pwm_output
    name: "Aquarium"
    id: aquarium
    default_transition_length: 0s
    gamma_correct: 5

  - platform: template
    name: "Dummy switch Aquarium"
    internal: true
    lambda: |-
      return (id(aquarium).current_values.is_on());
        - light.turn_on:
            id: aquarium
            brightness: 16.0%


found the solution, when using float i can use a 3 digit precision.

like 0.165 that does the trick for me.
