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.

   • Example in 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.
