+The **Ambient Weather Network** {% term integration %} retrieves local weather station information
+via the [Ambient Weather Network](https://ambientweather.net).
+
+Similar to the [Ambient Weather Station](https://www.home-assistant.io/integrations/ambient_station/)
+integration, this integration gathers sensor data from individual weather stations.
+However, in contrast to the [Ambient Weather Station](https://www.home-assistant.io/integrations/ambient_station/)
+integration, which exclusively enables owners to fetch data solely from their owned stations, this
+integration directly pulls public data from <https://ambientwether.net/> without requiring an API key,
+albeit with a reduced dataset (for example, excluding indoor sensors).
