If you want to define a specific interval at which your device is being polled for data, you can disable the default polling interval and create your own polling service.

1. Go to {% my integrations title="**Settings** > **Devices & Services**" %}, and select your integration.
2. On the integration entry, select the three dots.
   - Then, select **System options** and toggle the button to disable polling.

3. To define your custom polling interval, create an automation.
   - Go to {% my automations title="**Settings** > **Automations & Scenes**" %} and create a new automation.
   - Define any trigger and condition you like.
   - Under action, select **Call service** and use the [`homeassistant.update_entity` service](/integrations/homeassistant/#service-homeassistantupdate_entity).

   - Example in YAML.

      ```yaml
      automation:
         - alias: "Only update weather information every 20 minutes when I'm home"
            trigger:
               - platform: time_pattern
                 minutes: "/20"
            condition:
               - condition: state
                 entity_id: device_tracker.cynthia
                 state: home
            action:
               - service: homeassistant.update_entity
                 target:
                   entity_id: weather.home
      ```

4. Save your new automation to poll for data.
