Elbow Playground

Edit the YAML and the card redraws as you type. Pick a starting point (a header or footer elbow, or the segmented style), then change the elbow type, bar sizes or colours.

You don't need to know the YAML to start:

• Quick settings above the editor change the most common options for you.
• Type in the editor and it suggests the options that fit where your cursor is, with a short description. Press Ctrl+Space to see suggestions anywhere, and hover over a key to read what it does.
• Options here (under the editor) lists everything you can add at the cursor. Insert adds it at the right indent, and Docs opens its section in a new tab.

How the preview works

The preview is the real elbow card, the same code your dashboard runs. The docs site has no Home Assistant, so:

• Entities get sample values. The entities listed under the preview are always there, and any other entity id in your YAML gets a plausible value for its domain (lights and switches are on, sensors get a number with a unit).
• Taps that toggle switch the sample entity, so state colours change as on a dashboard. More info, navigate and other actions say what they would do instead.
• Jinja2 templates ({{ ... }}) need Home Assistant and render empty here; {entity.state} tokens and [[[ JavaScript ]]] templates work.
• Icons aren't drawn (Home Assistant provides them), and sounds are off.

Messages under the card show schema warnings for your YAML.

When it looks right, Copy YAML and paste it into your card's YAML editor, then swap in your own entities.
