GeoNet NZ Volcano

The geonetnz_volcano integration lets you use a GeoJSON feed provided by New Zealand’s GeoNet with information about volcanoes in the New Zealand region. It shows information of those volcanoes filtered by distance to Home Assistant’s location.

Entities are generated and updated automatically with each update from the feed. Each entity defines the volcanic alert level as its state. Latitude and longitude of the volcano are included as attributes to show on the default map automatically.

The data is updated every 5 minutes.
