Frontend automation does not want to work

[anoril1979]

Hi!

I've just installed ios-themes. Themes appear in the theme dropdown in the user parameters. Themes are well applied from there.

I then added your frontend automation file. Automations are well listed in my automation list. But when I click on "execute", nothing happens.
I set the entities panel with the theme selector input, aside with dark mode toggle and alternative theme toggle. Every thing is well presented on my lovelace. But when I selected a theme from the drop down list, toggle the dark mode knob or the laternative knob, nothing happens.

Using HA 2021.8.8, User Interface 20210909.0

Bas's frontend automations use a different set of theme files.

Try this instead:

automation:
  - alias: "Frontend: change theme"
    trigger:
      - platform: state
        entity_id: input_select.theme
      - platform: state
        entity_id: input_boolean.dark_mode
      - platform: state
        entity_id: input_boolean.theme_alternative
      - platform: homeassistant
        event: start
    action:
      - service: frontend.set_theme
        data:
          name: >
            {% set name = states("input_select.theme") -%}
            {% set mode = "dark" if is_state("input_boolean.dark_mode", "on") else "light" %}
            {% set suffix = "-alternative" if is_state("input_boolean.theme_alternative", "on") else "" -%}
            ios-{{ mode }}-mode-{{ name }}{{ suffix }}
