'Switch' to operate a stepper motor

Im 100% new to ESPHome, but not Arduino.

I need to know how to define a switch so that it directly tells a stepper motor to move a set number of steps. The examples only describe GPIOS or other commands.

Example, ‘on’ steps +500, ‘off’ steps -500

Have a read about automations. There is an actual stepper example linked on that page.

Define your stepper:

stepper:
  - platform: a4988
    id: my_stepper
    step_pin: D0
    dir_pin: D1
    max_speed: 250 steps/s

    # Optional:
    sleep_pin: D2
    acceleration: inf
    deceleration: inf

Define a binary sensor (your “switch”):

binary_sensor:
  - platform: gpio
    pin: D4
    name: "Stepper Control"

Add your automation to the binary sensor:

binary_sensor:
  - platform: gpio
    pin: D4
    name: "Stepper Control"
    on_press: #on
        then:
          # Move 500 steps forward
          - stepper.report_position:
              id: my_stepper
              position: 0
          - stepper.set_target:
              id: my_stepper
              target: 500
    on_release: #off
        then:
          # Move 500 steps backward
          - stepper.report_position:
              id: my_stepper
              position: 0
          - stepper.set_target:
              id: my_stepper
              target: -500

It gives you several examples of how to do this. The problem is we dont know what you mean by “define a switch” There are two types of switches you can define. Theres an actual physical switch wired to a gpio and a software switch where you would toggle it from HA. Each type requires a different way of doing it.


Now if you look at this example, the top line sais, on_…
That “…” willl depend on what your using to trigger the action. It could be on_press, on_click, on_state, on_turn_on, etc. So, depending on whether you use a gpio switch, a template switch, a binary sensor or whatever, it will tell you in the docs which one you need to use. For example, on_press, on_release are used for a binary sensor. If you used a switch, you would use on_turn_on and on_turn_off.

So you need to define you physical(gpio) switch or template switch(solftware) then you plug in the example from the stepper docs and you replace the (on_…) with whatever method your particular switch/button calls for just like it sais in the docs. Switch Component — ESPHome
