Tutorial #2, Part 1

In this tutorial, we are going to make the following wide card: 10-step-tutorial-02-part1-step10

Such a card is part of Example 12.

But as opposed to the example, we will create a toolset template for the 4 segmented arcs with icon and state displayed. So the result of the tutorial is in fact better than the original! And much shorter due to the use of templates.

Prerequisites

This tutorial requires:

  • An active Material 3 theme

Step 1: Create the yml view file

  • Create view-tutorial-02-part1.yml in the lovelace/views/sak-tutorial-views/ folder.
  • Add it to the sak-tutorials-dashboard.yaml in your root folder.

Step 2: Define the view basics, card, entities and layout

We are going to use 5 entities from the System Monitor integration.

              format: relative

          # Define aspect ratio
          aspectratio: 6/1

Step 3: Header, first column

The header is divided into three columns: the half circle with the icon, then the name and the state, and in the last header column the vertical line.

Define the first column of the header:

  • half a circle, which is in fact a full circle but clipped by the card due to our positioning the circles center at the card's edge.
  • a fixed icon

Step 6: Add segmented arc as part of the segarc, icon, state toolset

We design the toolset with a segmented arc tool, icon tool and state tool in this card before converting it to a toolset template.

The segarc consists of 4 segments, each having a slightly different primary Material 3 theme color.
