How to customize the badges at the top of the page?

Hello all,

As everyone does, I’ve put this in my configuration.yaml file:

themes: !include_dir_merge_named themes/

And it works perfectly.
My new wish is to create some additional info there like:

    primary-text-color: '#00cc00'
    label-badge-red: '#00cc00'
    primary-text-color: '#cc0000'
    label-badge-red: '#cc0000'

So I can use them to customize my badges. But how? If I put this under the !include_dir_merge_named, it fails with:

Apr 01 23:57:18 ERROR (SyncWorker_0) [homeassistant.util.yaml.loader] while scanning a simple key
Apr 01 23:57:18 ERROR (MainThread) [homeassistant.bootstrap] Failed to parse configuration.yaml: while scanning a simple key

Is there a way to complete/enhance this themes section in a way?

Thank you,


I’m not sure what your trying to do. Themes typically allow you to set the colors for the entire UI. Examples can be found in themes category in the Hacs add-on. But there are no ‘on:’/‘off:’ keys in those files. Perhaps you are trying to add styling as per the card-mod plug-in? In that case mods are added to the lovelace yaml files. Card-mod is also available through the Hacs add-on.

My initial wish is to colorize my badges (at the top of the pages), like I’ve put some binary sensors (ping) and want them red or green depending on the binary_sensor state.
For that, I’m using something found in this thread Custom UI - icon color change

In customize.yaml:

    theme: >
      if (state = on) {
        return 'on';
      } else {
        return 'off';

Then in the themes section of frontend, in configuration.yaml:

      primary-text-color: '#00cc00'
      label-badge-red: '#00cc00'
      primary-text-color: '#cc0000'
      label-badge-red: '#cc0000'

My understanding is that it will create 2 themes (called ‘on’ and ‘off’) that I will re-use in the customize.yaml to define the theme of my badges.

But my themes tag already contains:

themes: !include_dir_merge_named themes/

So I’m wondering how to add thoses ‘on’ and ‘off’ lines in the themes section of the configuration.yaml file.

Looked into the reference documentation you sited. Most references are pretty old and the last update to the andrey-git seems to be about a year old. What version of ha are you using? Are you using Lovelace for your ui? Are you using the andrey-git Custom UI code? None of what you’re proposing to do will work without it as far as I can see.

Oops :slight_smile: ok
I’m using lovelace of course.
And my HA is the latest, always. So 107.7 at the time of writing.

So, I’m back at step 0, how will I colorize my badges :frowning:

Try looking into card-mod 🔹 Card-mod - Add css styles to any lovelace card. This is what I use for css customizing in Lovelace.

I will. But it is not a badge at the side of an entity, inside a card but the one on top of a page. I’ll have a look to see what is possible with Card-mod.

Then I assume you are using the auto Lovelace ui and not yaml mode. In that case you might look at the hacs themes. There is some amount of customization of the badge colors in them. Perhaps you can determine more of the badge color labels and change it that way. There’s discussions in the card-mod thread about how to find specific color labels that will help.

Long story short, I was using the yaml before lovelace became the default interface but changed to the auto one since.
Changing the theme is something I can do, for sure, but:

  1. It breaks the automatic update if any
  2. It is time consuming and I wanted a quick win solution.

Thank you for the help you provided. I keep the card-mod idea in mind and will use it later for sure.

as far as I remember it has a section about working with badges so it is possible.
can’t say anything about themes as don’t use them.

You, yes you that came here looking for the answer, here it is :slight_smile:

  1. Install the card-mod extension (via HACS is the easiest)
  2. Activate card-mod in your lovelace config
  3. Use the following configuration (in yaml) for your badge:
  - badges:
      - entity: binary_sensor.bbox_ping
        icon: 'mdi:router-wireless'
        name: BBox
        style: |
          :host {
            --label-badge-blue: {% if is_state('binary_sensor.bbox_ping', 'on') %} green {% else %} red {% endif %};

Why --label-badge-blue? Because my badge was originaly blue. Not too hard huh?!

Pay attention to identation.
Here you are, you’re welcome.

Bye bye.

Thank you everyone:

  • @micque to lead me to card-mod
  • @AhmadK to confirm that badges was a viable option.

Btw, I’ve change the title as it was more a custo issue, not a yaml/tag one.
