Dashboard with dynamically background

Configuration Frontend

Ive found this to work, in my card-mod-themes:

  card-mod-view: |
    vertical-layout {
      {% set weeralarm = states['sensor.weer_alarm'].attributes.icon_color
        if is_state('binary_sensor.meteoalarm_brabant','on') %}
      background: {{weeralarm}};
    }
    hui-sections-view {
      {% set weeralarm = states['sensor.weer_alarm'].attributes.icon_color
        if is_state('binary_sensor.meteoalarm_brabant','on') %}
      background: {{weeralarm}};
    }

be ware though that while the vertical-layout colors the complete background, and goes beyond the last card, just as the window stretches, the hui-sections-view ends at the last section, which, if the required vertical space for that section is less than the window, looks really ugly…

Maybe there is another way of doing it, not sure yet, Sections is still experimental after all… We can add some empty grids in that section to make it use more background, but ofc that is plain silly

Hi,
I tried in a “section” type view but it didn’t work.
I currently use the ‘frontend’ mode to edit lovelace and I would like to change the background of only one specific tab (of type ‘section’) based on the entity sun.sun.
Could you please detail how you applied it?
Thanks

dont think it can be any more detailed.

If you use themes you can use card-mod-theming to set things system wide on particular elements, in this case a type of view.

check the instructions in the card-mod repo on the subject.

I take it with

you mean the UI editor opposed to Yaml mode? tbh, I dont use that a lot, and it really is a pain to have to copy all of that code in the editor…

I haven tried to set a mod on a single Sections view in Yaml mode yet, so cant say how to do that.

I did notice that the colorization was different than on a regular view, as those regular vies are colored all the way done to the view window, even if that is taller than the actual view. WIth sections, the colored background stops at the bottom of the section, and if the window of the view is taller (like on desktop) the rest gets the regular theme setting color.

Which I found really ugly, so I stopped using it altogether for now

Well I finally got this to work using the code below. I can change the background based on a variable. Thanks to all who gave their advice and opinions. I only have one problem now. I am not able to edit the code using the conventional ‘Edit’ on this page (clicking the pencil in the upper right corner). The only way I can edit is with the Raw Configuration Editor.

Just wanted to post what I had in case someone else stumbles on this while researching the same topic.
