New user trying to understand fields in scripts

Configuration
1

I’m trying to build a series of scripts to automate a laser cat toy that I’ve build, using esp32home.

I’ve exposed the laser and the pan / tilt via esphome and have manual control of it just fine.

Now I want to automate movement and timing using scripts.

I figured I’d start simple and have a script that takes two variables for pan/tilt and set the state.

The code is:

alias: Move Cat Toy
fields:
  rotate:
    selector:
      number:
        min: -100
        max: 100
        step: 1
        unit_of_measurement: float
    name: Rotate
    description: Rotate value for cat toy
    default: -69
    required: true
  tilt:
    selector:
      number:
        min: -100
        max: 100
        step: 1
        unit_of_measurement: float
    name: Tilt
    description: Tilt value for servo
    required: true
    default: -33
sequence:
  - device_id: b93d5e0023fa0e93fa719916f6da64f3
    domain: number
    entity_id: b7fbf0ea9ee681f1ce2b38038a5e40fd
    type: set_value
    value: 0
  - device_id: b93d5e0023fa0e93fa719916f6da64f3
    domain: number
    entity_id: d79cf1e684bae7d9f0ca86b4c9a30899
    type: set_value
    value: 0 
mode: single
icon: mdi:cursor-move

I was expecting that I could just substitute in the fields to the value section and I’d be good to have it work, but that gives me an error.

...
  - device_id: b93d5e0023fa0e93fa719916f6da64f3
    domain: number
    entity_id: b7fbf0ea9ee681f1ce2b38038a5e40fd
    type: set_value
    value: "{{ rotate }}"
  - device_id: b93d5e0023fa0e93fa719916f6da64f3
    domain: number
    entity_id: d79cf1e684bae7d9f0ca86b4c9a30899
    type: set_value
    value: "{{ tilt }}"
...

Error: Message malformed: expected float for dictionary value @ data['value']

How do I coerce what seems to be a type conversion problem?

Device Actions do not support templates.

Use a Number entity’s number.set_value service call.

- service: number.set_value
  target:
    entity_id: number.your_number_entity
  data:
     value: "{{ rotate }}"
