HomeAssistant-AEMET

IMPORTANT NOTICE:

Home Assistant now has native support for AEMET, so development of this component is stopped.

NOTA IMPORTANTE:

Home Assistant ahora soporta AEMET de forma nativa, así que el desarrollo de este componente está parado.

A Home Assistant custom-component that retrieves current information and weather forecasts published by AEMET (Agencia estatal de meteorología).

⚠️ As this is the Spanish governmental meteorological agency, only information on locations in Spain is published. ⚠️

The information is obtained from weather stations distributed throughout Spain.

To use this component in your Home Assistant you will need to obtain a personal/private API KEY from AEMET Open Data.

🇪🇸 All information is in Spanish. 🇪🇸

Getting started

Place the files of aemet component at this location on your setup:

• Hass.io: /custom_components/aemet/
• Hassbian / Other: <config directory>/custom_components/aemet/

And then restart Home Assistant to make sure the component loads.

Due to how custom_components are loaded, it is normal to see a ModuleNotFoundError error on first boot after adding this, to resolve it, restart Home-Assistant.

Example configuration.yaml

This configuration will load the component with your current location as defined at your Home Assistant.

weather:
  platform: aemet
  api_key: !secret aemet_api_key

You can add optional parameters to configure your component:

weather:
  platform: aemet
  name: el_tiempo
  api_key: !secret aemet_api_key
  latitude: 40.4169019
  longitude: -3.7056721

Config options

The following table shows all the options that can be used to configure your component.

There is only one mandatory parameter api_key, any other parameter is optional.

key	required	default value	description
api_key	Yes	N/A	Your private api key from AEMET.
name	No	aemet	Name of your component. If you have several instances of this component you need to have different names.
latitude	No	Home Assistant Latitude	Latitude of your location
Longitude	No	Home Assistant Longitude	Longitude of your location
elevation	No	0.0	Elevation of your location.
mode	No	daily	Type of forecast: hourly or daily
cache_dir	No	aemet	Directory where to cache some files. Location is relative to your config directory, but you can use a full qualified path. e.g. cache_dir: aemet and cache_dir: /config/aemet are equivalent

Other config options (for experimental use, can be removed in future versions)

key	required	default value	description
weather_station	No	N/A	Code of weather station to retrieve data instead of looking for the nearest one
city	No	N/A	Code of city (as defined by INE on http://www.ine.es/daco/daco42/codmun/codmunmapa.htm) to retrieve data instead of looking for the nearest one
experimental	No	False	If true the search for nearest weather station or city will be done by using a KDTree (requires scipy package). Some changes in aemet.py file should be done to uncomment some code.

How to obtain your API KEY

How data is processed

AEMET produces 3 types of data...

• Conventional observation with data from the last 24 hours
• Hourly forecast with the forecast of the next 72 hours
• Daily forecast up to 5 days.

All information is collected and preprocessed to match the way " Home Assistant " can work with it.

Currently Weather

The "current" information is obtained from weather stations which are updated hourly, but depending on the station there will be some information or other available.

For example:

• Station 1111X (Santander CMT) has 9 sensors: "precipitation", "wind_speed", "wind_bearing", "pressure", "humidity", "templow", "temperature", "dew_point" and "visibility".

• Station 3194U (Madrid - C. Universitaria) has 6 sensors: "precipitation", "wind_speed", "wind_bearing", "humidity", "templow", "temperature".

• Station 3194Y (Pozuelo de Alarcon, Madrid) has 4 sensors: "precipitation", "humidity", "templow", "temperature".

If some information is not available but it is available in forescast data, then it is obtained from the hourly forecast information for the current time.

Weather Forecast

Weather Forecast is obtained for Locations not directly from Weather Station.

AEMET produces forecast data for:

• Days D and D+1: Some sensors get information for 6 hours interval, 12 hours interval and whole day.
• Days D+2 and D+3: Some sensors get information for 12 hours interval and whole day.
• Day D+4: Sensos get information for whole day.

We present information on daily basis except for current day that will present the information from 6 hour interval.
