By defining a custom polling interval, you can control how frequently your system checks for new data, which can help optimize performance and reduce unnecessary network traffic. [Learn more] data from the service every 60 minutes by default.
Known limitations
Data is delayed by up to 24 hours (and can even last longer if there are issues with the smart metering service).
Home Assistant will only poll the API for new data once every 60 minutes as your smart meter does not frequently report changes.
