How to create functional cards

The next step: create functional cards!

In the end, we all want functional cards, no matter what look & feel we are using. We want something for binary and analog sensors, switches, power outlets, etc.

This section, and the next sections is all about creating such cards.

The steps I normally take to work from a certain look & feel to functional cards is as follows:

  • Create some cards to establish that look & feel.
  • Make a list of functional cards you like to have
  • Sketch them
  • Create them

Now depending on how you want to work you:

  • create SAK toolset templates from the start, just as I show in one of th 10 Step Tutorials. This can save you a lot of time creating functional cards, as you can re-use parts from the beginning!
  • Create all cards first, check the similar toolsets, and create SAK templates

The same holds true about using CSS Classes:

  • Create user CSS Classes from the start of your design
  • Or experiment first with several cards, before creating those classes.

Either way: you will get your functional cards!

This section serves as an example of functional cards, not as a starting point to win a Red-Dot Award!

Step 1: Choose your look & feel

For these sections, I choose Example 12: as the basis for creating some example functional cards.

These pages is still a work in progress, so AS IS

This example view requires one of the Home Assistant Material 3 Themes

Step 2: Make a list

I use a Mobile First approach. All cards should be readable and usable on my iPhone. So cards can't be very small!

In most cases that means for the card size:

  • Cards to fit a 1 column grid
  • Cards to fit a 2 column grid
  • Cards to fit a 3 column grid

4 column cards are too small on my mobile, hence I don't use or create them.

Step 3: Sketch some cards

I made some rough sketches based on the example 12 card:, but also used some cards I made as the basis to create other variants and cards.

Step 4: Create them

Last step is to create the cards you need.

As an example, I created a bunch of functional cards for inspiration and learning. Check the next page for that!
