Weather Underground (WUnderground)

The wunderground platform uses Weather Underground as a source for current weather information.

Obtain a WUnderground API key here. A free account allows 500 requests per day and also a maximum of 10 per minute. See details here.

To add Wunderground to your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: wunderground
    api_key: your_api_key
    monitored_conditions:
      - alerts
      - dewpoint_c

Configuration variables:

  • api_key (Required): The API key for Weather Underground. See above for details.
  • pws_id (Optional): You can enter a Personal Weather Station ID. The current list of Wunderground PWS stations is available here. If you do not enter a PWS ID, the current location information (latitude and longitude) from your configuration.yaml will be used to display weather conditions.
  • lang (Optional): Specify the language that the API returns. The current list of all Wunderground language codes is available here. If not specified, it defaults to English (EN).
  • latitude (Optional): Latitude coordinate to monitor weather of (required if longitude is specificed). Defaults to coordinates defined in your configuration.yaml.
  • longitude (Optional): Longitude coordinate to monitor weather of (required if latitude is specified). Defaults to coordinates defined in your configuration.yaml.
  • monitored_conditions array (Required): Conditions to display in the frontend. The following conditions can be monitored.
    • alerts: Current severe weather advisories

Forecasts

12 hour forecasts

Monitored conditions marked above with [12h] are 12 hour forecasts. To get a forecast for different period/daytime replace the _1d_ part of the sensor name. e.g. weather_2n will give you forecast for tomorrow night. Valid values for day are 1 to 4 and valid values for daytime are d or n.

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 4.

Hourly forecasts

Conditions marked with [1h] are hourly forecasts. To get forecast for different hour, replace the number in the _1h_ part of the sensor name with 1 to 36. E.g. weather_24h will give you weather in 24 hours.
