Hello @tom_l, thanks again! It works

esphome:
  name: basement_ventilation_fan
  platform: ESP32
  board: esp-wrover-kit

wifi:
  ssid: "xxx"
  password: "xxx"

# Enable logging
logger:

# Enable Home Assistant API
api:
  password: "xxx"

ota:
  password: "xxx"

output:
  - platform: ledc
    pin: GPIO19
    frequency: 10000 Hz
    id: ventilation_fan_pwm

fan:
  - platform: speed
    output: ventilation_fan_pwm
    name: "Basement Ventilation Fan"

Just put the integration in on Home Assistant and the high-medium-low works out of the box. Tried with a lower frequency first but it made no sense. At 10000Hz it works just as I hoped.

Thanks for your help!
