How do I expose servo/number to automation?

ESPHome

I have a d1 mini and I’ve got a simple push button that I’m trying to use to operate a servo. There will only be two positions on the servo. I can get the button to show up in automation but not the servo. What am I doing wrong?

  name: test-blast-gate
  friendly_name: Test Blast Gate

  board: esp01_1m

  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Test-Blast-Gate Fallback Hotspot"
    password: 

captive_portal:

binary_sensor:
  - platform: gpio
    pin:
      number: 2
      mode:
        input: true
        pullup: true
    name: "Simple Push Button"

output: 
  - platform: esp8266_pwm 
    id: pwm_output 
    pin: GPIO0
    frequency: 50 Hz

servo: 
  id: blast_gate_servo 
  output: pwm_output

As far as I know that is not possible.
There is no servo domain in HA.
What you could do is create two buttons or scripts in ESP-Home that you can trigger from HA and have the buttons/scripts set the position of the servo.
Or you need to pass a value from HA to ESP-Home that is then sent to the servo as the position.

I think this could work…

number:
  - platform: template
    name: "Servo position"
    optimistic: true
    min_value: -100
    max_value: 100
    step: 1
    on_value:
      then:
        - servo.write:
          id: blast_gate_servo
          level: !lambda "return x/100;"

    pin:
      number: GPIO2
      mode: INPUT_PULLUP
      inverted: true
    name: "Simple Push Button"
    filters:
      - delayed_on: 50ms
      
    on_press:
      then:
        - lambda: |-
            static bool state = false;
            state = !state;
            
            if (state) {
              id(blast_gate_servo).write(1.0);  // 180 degrees
            } else {
              id(blast_gate_servo).write(-1.0); // 0 degrees
            }

I like this solution. I’ll try it out tonight. Thank you.

Not tested.
Map your servo angles though.
You’re welcome :wink:

This is what I did for continous servo’s. So as mentioned above, you’ll need to alter to fit your need i.e. the angles
