Data updates

The integration pollsData polling is the process of querying a device or service at regular intervals to check for updates or retrieve data. 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] the GeoSphere Austria warning service every 5 minutes. Each poll first checks whether GeoSphere Austria published new warning data, and only downloads the full data when something changed. No authentication or API key is required.

Known limitations

• Warnings are only available for locations within Austria.
• Warnings are resolved per municipality. Locations within the same municipality receive identical warnings, even if conditions differ locally.
• The integration reports the warnings published by GeoSphere Austria as-is; it does not forecast or interpret weather data itself.

Troubleshooting

No Austrian municipality was found

The selected location is outside of Austria, or too far from any municipality boundary. Check the latitude and longitude, and select a location within Austria.

If this message appears for an entry that already worked before, the configured location can no longer be resolved to a municipality. Delete the entry and add it again with a location within Austria.

Entities are unavailable

The GeoSphere Austria warning service could not be reached. Check your internet connection and whether warnungen.zamg.at is reachable. The integration recovers automatically once the service is available again.
