Best method for default theme?

Configuration Frontend
1

What I’d like to do is set a default theme so when guests log in it doesn’t blind them. I tried the automation method and it didn’t seem to work. Is there an easier method I am overlooking?

You can attach a theme to the user

so you need to create a Guess user

I know how to change themes but this does not show me how to attach a theme to a user. I want it to be a specific theme on a certain user when they log in. In this case the guest user. If I log into this user on a different device it does not keep the dark theme I chose on my desktop.

Bumping for help.

I set up an automation that sets the frontend theme on HA start.

- id: '...'
  alias: Set Theme on HA Start
  description: ''
  trigger:
  - event: start
    platform: homeassistant
  condition: []
  action:
  - data:
      name: <theme_name>
    service: frontend.set_theme

This I’ve tried as well, but it does not change the default log in screen, which is still blindingly white.

did you find a solution ?

I’m also curious if a solution was found :slight_smile:

I am interested as well. I need to set up specific theme for kiosk mode (where is no option to adjust “user” settings)

not sure if this is what you want - but to set a default theme that any device will see when they open HASS, this worked for me…

in automations.yaml

- alias: 'Set theme at startup'
  trigger:
    platform: homeassistant
    event: start
  action:
    service: frontend.set_theme
    data:
      name: THEME_YOU_WANT

based on the docs:

and the info given above, I built this automation which triggers at HA start and sun up/down to switch themes:

alias: "Theme: Auto Change"
description: trigger at HA startup / sun up / sun down
trigger:
  - event: start
    platform: homeassistant
  - entity_id: sun.sun
    platform: state
    to: above_horizon
    id: up
  - entity_id: sun.sun
    platform: state
    to: below_horizon
    id: down
action:
  - choose:
      - conditions:
          - condition: trigger
            id: down
        sequence:
          - service: frontend.set_theme
            data:
              mode: dark
              name: day_and_night
      - conditions:
          - condition: trigger
            id: up
        sequence:
          - service: frontend.set_theme
            data:
              mode: light
              name: day_and_night
    default:
      - service: frontend.set_theme
        data:
          mode: light
          name: day_and_night
mode: single
