Hey OP,

I cant seem to get this working, I just get:

Invalid config for [automation]: required key not provided @ data['action']. Got None
required key not provided @ data['trigger']. Got None. (See /config/configuration.yaml, line 55). Please check the docs at https://home-assistant.io/components/automation/
Invalid config for [automation]: required key not provided @ data['action'][0]['delay']. Got None. (See /config/configuration.yaml, line 55). Please check the docs at https://home-assistant.io/components/automation/

It’s not this automation that is causing you a problem - the error message mentions a delay: paramater, which does not feature in the automation in the OP.

but if I remove this automation it works again…

5

Maybe when you’re pasting it in it is not aligned correctly with your other automations so homeassistant is reading another as part of this one.

6

Does this automation, as it appears in OPs post, work on the latest version of home assistant for you?

If I know it’s currently working for SOMEONEon the same as me it’s defs something I’m doing wrong :thinking:

7

Mine is slightly different, but code wise it is the exact same principle…

automation:
  - alias: Interface - Set UI theme
    initial_state: on
    trigger:
      - platform: homeassistant
        event: start
      - platform: state
        entity_id:
          - alarm_control_panel.alarm
          - input_boolean.maintenance_mode
      - platform: state
        entity_id: input_boolean.dark
      - platform: time
        at: '23:00:00'
      - platform: time
        at: '07:00:00'
    action:
      service: frontend.set_theme
      data_template:
        name: >
          {% if not is_state ('alarm_control_panel.alarm' , 'disarmed') %} darkred
          {% elif is_state ('input_boolean.maintenance_mode' , 'on') %} darkorange
          {% elif ((now().hour == 23) or (now().hour < 7)) %} darkcyan
          {% elif is_state('input_boolean.dark' , 'on') %} midnight
          {% else %} default {% endif %}

I have been trying to firgure this out for the last 3 days why it wasn’t working. I am new to HASS and thought if i can’t figure this out then don’t go further. I copied mine from a youtube video and i have just realised that i needed to add a space infron of Name so the N lined up with the A in Data_template.

10

The N for name should be under the T of data in data_template. All spacing is in twos.

Hello, i make it alf working, all the “armed” stuf change the theme.
But the disarmed mod don’t change anything:
Can anyone help meplease ? i am completely stuck for 1week.

automation:
- alias: test3651685215
  description: ''
  trigger:
  - entity_id: alarm_control_panel.home_alarm
    platform: state
  condition: []
  action:
    service: frontend.set_theme
    data_template:
       name: >
        {% if is_state ('alarm_control_panel.alarm' , 'disarmed') %} clear-dark
        {% elif is_state ('alarm_control_panel.home_alarm' , 'armed_home') %} dark_orange
        {% elif is_state ('alarm_control_panel.home_alarm' , 'armed_away') %} material_dark_red
        {% endif %}
12

I suspect the theme is called clear_dark not clear-dark

trigger:
  - platform: state
    entity_id: sun.sun
condition: []
action:
  - choose:
      - conditions:
          - condition: sun
            before: sunrise
            after: sunset
        sequence:
          - service: frontend.set_theme
            data:
              name: BlueNight
      - conditions:
          - condition: sun
            before: sunset
            after: sunrise
        sequence:
          - service: frontend.set_theme
            data:
              name: ais
    default: []
mode: single
