blueprint:
  name: "Omnibattery - Forward Persistent Notifications To Telegram"
  description: >
    Forwards Home Assistant persistent notifications to a Telegram chat.

    Default behavior:
    - Fires when a persistent notification is added or updated (not on reload,
      so existing notifications are not re-sent every restart).
    - Sends the title, ID and message to the selected Telegram notify entity,
      HTML-escaping the dynamic fields so any character is delivered safely.
    - By default forwards only this integration's notifications (IDs start with
      "marstek_venus_"). Clear the prefix to forward every persistent
      notification, or set a different prefix.
