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 or 10 per minute.

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

Configuration variables:

  • api_key (Required): See above.
  • 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).
  • monitored_conditions array (Required): Conditions to display in the frontend. The following conditions can be monitored.
    • alerts: Current severe weather advisories
    • dewpoint_c: Temperature in Celsius below which water droplets begin to condense and dew can form
    • dewpoint_f: Temperature in Fahrenheit below which water droplets begin to condense and dew can form
