This ESPHome package allows control of blinds using a stepper motor.

TLDR; Add this to your ESPHome device configuration:

substitutions:
  stepper_dir_pin_inverted: 'false'
  stepper_dir_pin: D6
  stepper_step_pin: D7
  stepper_enable_pin: D5
  stepper_max_speed: '250'
  stepper_endstop: '650'

packages:
  blinds: github://tronikos/esphome-blinds/esphome-blinds.yaml@main

esp8266:
  board: d1_mini
  restore_from_flash: true

Follow this video guide by The Hook Up but skip their software installation:

Wiring diagram (from https://github.com/thehookup/Motorized_MQTT_Blinds):

Don't forget to cut the center trace on the stepper motor as shown in the youtube video.

1. Setup ESPHome, if you don't have it already, by following Getting Started with ESPHome and Home Assistant.
2. In the ESPHome Dashboard select New device, Continue, give a name: e.g. Kitchen blinds, Next, select device type based on the ESP chip used e.g. ESP8266.
3. In the Configuration created! page select Skip to skip installation for now until we make a few changes.
4. Select Edit on the created configuration e.g. kitchen-blinds.yaml.
5. Skip this step if you used an esp32. Change esp8266 section to:

esp8266:
  board: d1_mini
  restore_from_flash: true

6. Add the following (either at the beginning or the end of the file):

substitutions:
  stepper_dir_pin_inverted: 'false'
  stepper_dir_pin: D6
  stepper_step_pin: D7
  stepper_enable_pin: D5
  stepper_max_speed: '250'
  stepper_endstop: '650'

packages:
  blinds: github://tronikos/esphome-blinds/esphome-blinds.yaml@main

7. Change the values in the substitutions section based on your setting, e.g. if you have used different pins. The stepper_endstop: '650' for my blinds corresponds to the blinds being open, i.e. parallel to the ground -. For some of my blinds I have stepper_dir_pin_inverted set to false while for others I have true depending on how I like them in closed position, i.e. / or \.
8. Your configuration should now look something like the following:

substitutions:
  stepper_dir_pin_inverted: 'false'
  stepper_dir_pin: D6
  stepper_step_pin: D7
  stepper_enable_pin: D5
  stepper_max_speed: '250'
  stepper_endstop: '650'
