Change scan_interval for image_processing from script/automation

1

Hi,

I want to have different scan_interval configuration from image_processing (for example, scan_interval: 1 for a minute when a motion sensor is activated), but I don’t get to do it, someone knows how to change scan_interval dynamically?

Thanks!

Unfortunately I don’t think you can.

The way I do it is to set a very long scan interval in the sensor itself and then have two scripts.

  1. The first works out the required delay (scan_interval) based on whatever criteria you need and then passes that to a second script.

  2. The second script has a delay which is the length of time you want to wait between updates (which you passed to this script) before it calls the homeassistant.update_entity service. Finally it starts script 1 again.

@klogg could you please post more information about your solution, I would like to implement it but don’t fully understand it, thanks

Something like this:

automation:

  - alias: Sensor Update
    trigger: 
      - platform: homeassistant
        event: start

    action:
      #== stop the looping scripts
      - service: script.turn_off
        entity_id:
          - script.set_sensor_update_interval 
          - script.loop_set_sensor_update_interval

      - delay: "00:00:02"

      #=== Start the loops
      - service: script.set_sensor_update_interval


script:
  #========================
  #=== Set update interval sensor
  #========================
  set_sensor_update_interval:
    sequence:
    
      #== Stop the looping script
      - service: script.turn_off
        entity_id: script.loop_set_sensor_update_interval

      - delay: "00:00:01"

      #=== Call the looping script to set the sensor interval
      - service: script.loop_set_sensor_update_interval
        data_template:
          interval: >
            {% if [SOME_CONDITION] %}
              12:00:00
            {% elif [SOME_OTHER_CONDITION %}
              1:00:00
            {% else %}
              00:00:30
            {% endif %}
      

  #====================================
  #=== Looping script that sets the sensor interval 
  #====================================
  loop_set_sensor_update_interval:
    sequence:
      #=== update the sensor
      - service: homeassistant.update_entity
        entity_id: sensor.SOME_SENSOR

      - delay: "{{ interval }}"

      - service: script.set_sensor_update_interval

thanks I will try to implement that solution
