Restoring persistent notifications on restart

[VDRainer]

Replace the original condition.

also what does the [:5] indicate? I added this as an and condition and none of my notifications are being saved now. I have the ID’s set to be

That indicates that only notifications created with notification_id that matches the first 5 characters (myha_) are saved and restored.

      - service: persistent_notification.create
        data:
          title: "Bresser 3CH"
          message: "Sensor Timeout"
          notification_id: "myha_bresser_notify"

All right I think I understand… but it isn’t working. The notifications do publish to the mqtt broker but when I restart home assistant they do not restore. In my logs I am seeing the following error:

Error during template condition: UndefinedError: 'dict object' has no attribute 'event'

when I run the template thru the template editor I get this:

Error rendering template: UndefinedError: 'trigger' is undefined

When I restart I get the following message with no content on my mqtt broker:

Message 19 received on home-assistant/notifications/config_entry_discovery at 8:36 PM: QoS: 0 - Retain: false

This is my full config:

    initial_state: 'on'
    trigger:
      - platform: event

        event_data:

    condition:
      - condition: template
        value_template: >

        data_template:

            {{ trigger.payload_json.title }}
          message: >-

          notification_id: >-
            {{ trigger.payload_json.notification_id }}

EDIT: This works if I use your condition for the ‘create’ automation but use the original condition for the ‘restore’ automation. Weird.

EDIT 2: Oh wow I am stupid. I just re-read your post and you never said to use it in the restore automation. Jesus. Thanks for your help!!!
