28BYJ-48 stepper motor with Wemos D1 Mini

ESPHome
1

I am trying to get my stepper motor (with ULN2003 control board) working with HA.
I want a slider to adjust the rotation of my stepper motor.
However, I cannot get it working in HA. (My setup works in Arduino, so I think my wiring is correct.)

My automations.yaml code:

- id: zonnelogger
  alias: Write stepper Value to ESP
  trigger:
  - platform: state
    entity_id: input_number.stepper_control
  action:
  - service: esphome.zonnelogger_control_stepper
    data_template:
      target: '{{ trigger.to_state.state | int }}'

my configuration.yaml code:

input_number:    
  stepper_control:
    name: Stepper Control
    initial: 0
    min: -1000
    max: 1000
    step: 1
    mode: slider

My ESPHome code (zonnelogger.yaml)

esphome:
  name: zonnelogger

esp8266:
  board: d1_mini

# Enable logging
logger:

# Enable Home Assistant API
api:
  services:
    - service: control_stepper
      variables:
        target: int
      then:
        - stepper.set_target:
            id: my_stepper
            target: !lambda 'return target;'

ota:
  password: "***"

wifi:
  ssid: ***
  password: ***

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Zonnelogger Fallback Hotspot"
    password: "***"

captive_portal:
    
stepper:
  - platform: uln2003
    id: my_stepper
    pin_a: GPIO5
    pin_b: GPIO4
    pin_c: GPIO0
    pin_d: GPIO2
    max_speed: 250 steps/s
    sleep_when_done: true    
    step_mode: FULL_STEP

    # Optional:
    acceleration: inf
    deceleration: inf

I am completely clueless! Any advice is greatly appreciated!

That is not an error message. Logs? what happens when you try to use the service?

Thank you! This comment led to the solution.
I didn’t check the logs in HA. I was only looking at the logs in ESPHome.
The logs told me there was no connection to the ESPHome from HA.

I simply forgot to add this board into Integrations. (Add Integration → ESPHome → host: name.local for anyone wondering in the future.)
Now I have a good connection and it works!

Would you be so kind as to share what pins I would use with the ESP8266 I see you posted the pins for the mini:

pin_a: GPIO5
    pin_b: GPIO4
    pin_c: GPIO0
    pin_d: GPIO2
