Configure Lovelace dashboards in YAML mode by defining views, cards, and themes with proper indentation and entity IDs. Start with a basic template organizing views by layout type—Masonry, Panel, Sections, or Sidebar—then add built-in or custom cards with their required properties.

Lovelace offers four view layouts: Masonry arranges cards in a responsive grid, Panel displays full-screen content, Sections organizes cards into collapsible groups, and Sidebar adds a navigation panel. Choose based on your dashboard organization needs and content density.

Yes, Lovelace supports 40+ built-in cards plus custom cards installed via HACS. Configure custom cards by referencing their resource URLs and following their specific YAML schemas to extend dashboard functionality beyond standard components.

Customize Lovelace themes by defining CSS variables in your theme YAML file, then apply the theme globally or to specific views. This controls colors, fonts, and layout styling across your dashboard without modifying individual cards.

Lovelace YAML requires consistent indentation, valid entity IDs, and all required properties for each card type. Common errors stem from incorrect nesting, missing colons, or mismatched entity references—validate structure before deployment.

Home Assistant supports both YAML and storage modes for Lovelace configuration. YAML mode offers version control and manual editing, while storage mode uses the UI editor; each approach has different backup and portability implications.
