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
Exactly what i have been looking for except I want to use D4 for open and D5 for close . The link doesn’t work anymore I suppose its an old post. Any help appreciated
Took me less than 30s of searching on the esphome site, but this is what you were looking for Automation — ESPHome
How do you plan to do that if your using a stepper motor?
You need to just read through the different components your using in the esphome documentation because, thats where you find this information and learn how to do things.
