  • themes

Plugins can be turned off and on in the Plugins section of the "config.json" file.

Custom Themes​

With this plugin you can define a custom theme for the Management Center, including a custom logo. You find the settings for your themes in the "config.json" file under "themes".

It looks a little like this:

 "themes": [
        {
            "id": "custom",
            "name": "Cedalo AG",
            "light": {
                "logo": { }}}]

Exchange current wordings, logos, colors by replacing the default values. The image files for the logo are encoded in base64.

"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAABL4.."

An easy way to encode your own images is via base64 image.
