Esphome controlling servos ??

[Gromyjoe]

I'm working on automating my airflow dampers before winter. Cant seem to get the example on esphome.io to work.. I get stupid syntax errors in the esphome yaml.
I'll post my current yamls in a bit.. but if theres a simpler way of opening and closing dampers I'm keen to hear what you guys have!!

in case someone needs this. im not sure how im going to add this to my setup, i have a servo for cold air in, one for recirculation and one for hot air out.
esphome create a node and setup as you would then add this

Code: Select all

api:
  services:
    - service: control_dump_servo
      variables:
        level: float
      then:
        - servo.write:
            id: servo_dump
            level: !lambda 'return level / 100.0;'

and this

Code: Select all

output:
  - platform: esp8266_pwm
    id: dump_servo
    pin: D3
    frequency: 50 Hz
    servo:
  - id: servo_dump
    output: dump_servo

configurations.yaml

Code: Select all

 control_dump_servo:
    initial: 0
    min: -45
    max: 45
    step: 5
    mode: slider

automations.yaml

Code: Select all

- id: '1601217169190'
  alias: Dump Servo Control
  description: ''
  trigger:
  - platform: state
    entity_id: input_number.control_dump_servo
  condition: []
  action:
  - service: esphome.hvac_servo_controller_control_dump_servo
    data:
      level: '{{ trigger.to_state.state | int }}'
  mode: single

I used the same basic code to build:
