Home Assistant Dashboards & Cards

Workflow

• Determine whether to create a new dashboard or edit an existing one.
• If editing, locate target cards first and transform config with a current config_hash.
• Use built-in cards unless a custom card is required.
• Discover entity IDs before wiring cards.
• Provide minimal, valid dashboard snippets or tool-driven changes.
