Parameters:

    The email address to hide notifications for. If nil, hide broadcast notifications.

  • id (String, nil) (defaults to: nil) —

    hide notifications associated with the given reference ID.

  • tag (String, nil) (defaults to: nil) —

    hide notifications associated with the given tag.

This method returns an undefined value.

Send a notification using openHAB Cloud Notification Action.

Examples:

Send a broadcast notification via openHAB Cloud

rule "Send an alert" do
  changed Alarm_Triggered, to: ON
  run { Notification.send "Red Alert!" }
end

Provide action buttons in a notification

rule "Doorbell" do
  changed Doorbell, to: ON
  run do
    Notification.send "Someone pressed the doorbell!",
      title: "Doorbell",
      attachment: "http://myserver.local/cameras/frontdoor.jpg",
      buttons: {
        "Show Camera" => "ui:/basicui/app?w=0001&sitemap=cameras",
        "Unlock Door" => "command:FrontDoor_Lock:OFF"
      }
  end
end

Parameters:

  • msg (String) —

    The message to send.

  • email (String, nil) (defaults to: nil) —

    The email address to send to. If nil, the message will be broadcasted.

  • icon (String, Symbol, nil) (defaults to: nil) —

    The icon name (as described in Items).

  • tag (String, Symbol, nil) (defaults to: nil) —

    a name to group the type or severity of the notification.

  • severity (String, Symbol, nil) (defaults to: nil) —

    Deprecated - an alias for tag for backwards compatibility.

  • title (String, nil) (defaults to: nil) —

    The title of the notification. When nil, it defaults to openHAB inside the Android and iOS apps.

  • id (String, nil) (defaults to: nil) —

    An optional reference ID which can then be used to hide or update the notification. Subsequent notifications using the same reference ID will update/overwrite the existing notification with the same ID.

  • on_click (String, nil) (defaults to: nil) —

    The action to be performed when the user clicks on the notification. Specified using the action syntax.

  • attachment (String, Item, nil) (defaults to: nil) —

    The URL of the media attachment to be displayed with the notification. This can either be a fully qualified URL, prefixed with http:// or https:// and reachable by the client device, a relative path on the user's openHAB instance starting with /, or an image item.

  • buttons (Array<String>, Hash<String, String>, nil) (defaults to: nil) —

    Buttons to include in the notification.

    • In array form, each element is specified as Title=$action, where $action follows the action syntax.
    • In hash form, the keys are the button titles and the values are the actions.

    The maximum number of buttons is 3.
