Turn off the polling toggle and click UPDATE.

disable_polling

You can now write an automation to update the integration’s entities with whatever* frequency you want, e.g.

trigger:
  - platform: time_pattern
    hours: "/3"
action:
  - service: homeassistant.update_entity
    target:
      entity_id:
        - sensor.my_sensor_1
        - sensor.my_sensor_2

Notes:

  • The integration will still poll once if your system is restarted or the integration is reloaded.

  • * Do not abuse this to poll external APIs you do not own by scanning too frequently. This may result in the API owner removing access for all users.

When I do this, even if I just run the automation once, it seems like the Prusalink integration keeps polling after - I’m seeing errors in my logs every 90 seconds that it’s trying and failing.

I believe there is an open issue about repeats for failed polling. I’ll see if I can find it later.

EDIT: can’t find it. I’ve asked for guidance and the advice is to open a new issue here:

Please provide as much detail as possible, screen shots of the disabled polling toggle, the automation you used to poll the entity and the errors you receive, and how often.
