blueprint:
  name: "Omnibattery - Central Status Webhook Reporter"
  description: >
    Periodically sends selected Omnibattery and Home Assistant entity states to
    a central HTTP endpoint. The endpoint is configured once as a
    rest_command; this blueprint configures the site identifier, the entities
    to report, and the interval.

    Before using this blueprint, define the selected rest_command in
    configuration.yaml with payload: "{{ report }}". The documentation gives
    a complete example. Treat the endpoint URL as a secret.
