AEMET OpenData

The AEMET weather platform uses AEMET OpenData as a source for current meteorological data for your location. AEMET stands for “Agencia Estatal de Meteorología”, which is the Spanish Meteorological Agency.

There is currently support for the following device types within Home Assistant:

You need an API key, which is free but requires a registration. The AEMET OpenData service is completely free but is limited to the Spanish territory.
