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.
