How to render data template before call to script?

hcjehg · October 13, 2024, 11:14am

Hello

I have been trying this for a long time, in all kinds of ways.

I have a script that takes two parameters (fields temperature and useoffsets))

alias: SetTemperature
description: Set the Temperature
icon: mdi:home-thermometer
fields:
  temperature:
    selector:
      number:
        min: 5
        max: 32
        step: 0.5
    name: Temperature
    description: Temperature to set
    required: true
    default: 15
  useoffsets:
    selector:
      boolean: {}
    name: useoffsets
    required: true
    description: Use Thermostat Offset or not
sequence:
  - action: input_select.set_options
    metadata: {}
    data:
      options:
        - On/Automatic
    target:
      entity_id: input_select.heating_mode
  - action: input_number.set_value
    target:
      entity_id: input_number.set_bedroom_temperature
    data:
      value: >-
        {% if false==useoffsets %}  {{ temperature|float }}  {% else %} {{
        states('input_number.offset_bedroom_temperature')|float +
        temperature|float }} {% endif %}

When I call this script from an automation, then it works perfectly well…

alias: New automation
description: ""
triggers: []
conditions: []
actions:
  - action: script.settemperature
    data:
      temperature: "{{ states('input_number.temperature_day')|float}}"
      useoffsets: true
mode: single

However, when I call from a button (the second one) on an entities card
(The first button with constant value 10 works perfectly)

type: entities
state_color: true
entities:
  - type: button
    name: 10 degrees
    entity: script.settemperature
    icon: mdi:thermometer-low
    tap_action:
      action: perform-action
      perform_action: script.settemperature
      data:
        temperature: 10
        useoffsets: false
  - type: button
    name: Day temperature
    entity: script.settemperature
    icon: mdi:thermometer-low
    tap_action:
      action: perform-action
      perform_action: script.settemperature
      data:
        temperature: "{{ states('input_number.temperature_day')|float }}"
        useoffsets: true

then I get:

It is as if the template does not get rendered, when used in a button …but it does get rendered when executed from an Automation… ???

What am I doing wrong ?

If you have any ideas on how to fix my script call in the button, they are very welcome

Correct. Very few core cards support templates.

Pass the entity id to your script and put the template in your script.

Thank you for your feed back

Am I to understand that the Buttons on cards (and perhaps elsewhere) does not use the actions used by e.g. automations (which does support templates) ?
Basically that: “Actions” are not simply “Actions”

tom_l · October 13, 2024, 1:41pm

This is a template:

Most core cards do not support them.

The actions performed by the frontend (dashboard cards) are not the same as actions performed by the backend (scripts and automations).
