Home Assistant

Buienradar Sensor

The buienradar platform uses buienradar.nl as a source for current meteorological data for your location. The weather forecast is delivered by Buienradar, who provides a web service that provides detailed weather information for users in The Netherlands. The relevant weather station used will be automatically selected based on the location specified in the Home Assistant configuration (or in the buienradar weather/sensor component). A map of all available weather stations can be found here.

The selected weather station will provide all weather data, with the exception of the forecasted precipitation. The forecasted precipitation data will be retrieved from buienradar using your actual gps-location (and not the location of the nearest weather station).

To integrate buienradar with Home Assistant, add the following section to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: buienradar
    monitored_conditions:
      - symbol
      - humidity
      - temperature
      - windspeed
      - pressure

Configuration variables:

  • name (Optional): You can specify a name of the component, but do not have to. If you specify a name, the sensors will get an entity name of sensor.[name]_[default sensor display name], for example:
    • sensor.lopik_temperature, since the name of the sensor is set to lopik and the default display name for monitored condition temperature is Temperature
    • sensor.lopik_wind_force, since the name of the sensor is set to lopik and the default display name for monitored condition windforce is Wind force

    If no name is specified the sensors will be called sensor.br_[default sensor display name], for example:

    • sensor.br_wind_speed, since no name has been set for the sensor and the default display name for monitored condition windspeed is Wind speed
    • sensor.br_ground_temperature, since no name has been set for the sensor and the default display name for monitored condition groundtemperature is Ground Temperature
  • latitude (Optional): Latitude to use for selection of data source location. Longitude and latitude will be taken from Home Assistant configuration, but can be overridden/changed in this component to select a different location for buienradar.nl.
  • longitude (Optional): Longitude to use for selection of data source location. Longitude and latitude will be taken from Home Assistant configuration, but can be overridden/changed in this component to select a different location for buienradar.nl.
  • timeframe (Optional): Minutes to look ahead for precipitation forecast (5..120) [default: 60].
  • monitored_conditions array (Required): One or more conditions to display in the frontend.
    • stationname: The name of the selected meteo-station.
    • conditioncode: A symbol and a unique code identifying the current weather condition ([a..z]).
    • condition: A symbol and the current weather condition (clear, cloudy, fog, rainy, snowy, lightning).
    • conditiondetailed: A symbol and detailed current weather condition (clear, partlycloudy, cloudy, partlycloudy-fog, partlycloudy-light-rain, partlycloudy-rain, light-rain, rainy, snowy-rainy, partlycloudy-light-snow, partlycloudy-snow, light-snow, snowy, partlycloudy-lightning, lightning).
    • conditionexact: A symbol with the full current weather condition (in English).
    • symbol: A symbol for the current weather with the full current condition (in Dutch).
    • humidity: The relative humidity (%).
    • temperature: The current temperature (in C).
    • groundtemperature: The current ground temperature (in C).
    • windspeed: The wind speed in m/s.
    • windforce: The wind speed/force in Bft.
    • winddirection: Where the wind is coming from: N (North),Z (south), NO (North-East), etc.
    • windazimuth: Where the wind is coming from in degrees, with true north at 0° and progressing clockwise.
    • pressure: The sea-level air pressure in hPa.
    • visibility: Visibility in meters (m).
    • windgust: The wind speed of wind gusts (m/s).
    • precipitation: The amount of precipitation/rain in mm/h.
    • precipitation_forecast_average: The average expected precipitation/rain in mm/h within the given time-frame.
    • precipitation_forecast_total: The total expected precipitation/rain in mm within the given time-frame. The total expected rain in the configured time-frame will be equal to precipitation_forecast_total/timeframe mm/min. So, with time-frame configured to 30 minutes and a value of 5, the expected rain is 5 mm in 30 minutes, which is the same as 10 mm/h. If time-frame is set to 90 minutes and a value of 5, the expected rain is 5 mm in 90 minutes, which is equal to 3.3 mm/h.
    • irradiance: Sun intensity in Watt per square meter (W/m2).
    • temperature_1d [1d]: The forecasted temperature (in C).
    • mintemp_1d [1d]: The forecasted minimum temperature (in C).
    • rainchance_1d [1d]: The forecasted chance for rain (%).
    • sunchance_1d [1d]: The forecasted chance for sun (%).
    • rain_1d [1d]: The forecasted amount of rain in mm.
    • snow_1d [1d]: The forecasted amount of snow in cm.
    • windforce_1d [1d]: The expected windforce in Bft.
    • conditioncode_1d [1d]: Symbol and condition code of the expected condition.
    • condition_1d [1d]: Symbol and expected condition.
    • conditiondetailed_1d [1d]: Symbol and detailed expected condition.
    • conditionexact_1d [1d]: Symbol and full expected condition (in English).
    • symbol_1d [1d]: Symbol and full expected condition (in Dutch).

Daily forecasts

Conditions above marked with [1d] are daily forecasts. To get forecast for different day, replace the number in _1d part of the sensor name. Valid values are from 1 to 5.
