Linked LovelaceReusable Card Templates

Keep your Home Assistant dashboards in sync with zero copy-pasting.

Define Once, Use Everywhere

Mark any card with ll_key and it becomes a template. Place it on as many dashboards as you like – one click syncs them all.

Pass ll_context to inject variables at render-time. Different dashboards can use the same template with different values.

Full if/else, loops, and partials via Eta JS. Write logic once in a partial and reuse it across all your templates.

Dynamically inject rendered card objects into template arrays. Build rows, lists, and grids with a single template.

Works with the Home Assistant 2024.3+ sections dashboard layout out of the box.

Core rendering logic is covered by a comprehensive test suite. Consistent output you can rely on.
