Question about usage

[TD22057]

I was wondering if you could help me. I’m trying to save the state of a binary_sensor from my alarm panel and restore both the state and the last_modified and last_updated times. After a restart, the sensor is “unknown” until the door/window is actdually toggled and the modified/updated times are the restart time which is useless. But there is no service call to change the state of a binary sensor so how does the restore action of the saver component work? I started writing this and got stuck with how to implement the restore portion. I also looked through the saver code and don’t see anywhere that it would actually be able to update the last_modified and last_updated times of a state in the state machine.

In my automations.yaml:

  - service: saver.save_state
    data:
      entity_id: binary_sensor.front_door

- id: saver_load
  - service: saver.restore_state
    data:
      entity_id: binary_sensor.front_door
      restore_script:
        - service:  ???

Thanks.

Saver technically doesn't restore anything, it just stores the state and provides a way to use it in a service call, so you can't do anything without an appropriate service.

Thanks - that's what I was afraid of.
