wunderground platform uses Weather Underground as a source for current weather information.
Obtain a WUnderground API key here. They no longer offer free API keys, and all keys must be paid for. At this time existing free keys will continue to work, but will be disabled Dec 31, 2018, except you own a personal weather station and provide your data to WU (PWS Uploader). As of Sept 6, 2018 Weather Underground states they are declaring the End of Service for the Weather Underground API. They say they will develop new plans for non-commercial users. No timeline for this has been announced. Please consider this when using the following information.
To add Wunderground to your installation, add the following to your
# Example configuration.yaml entry sensor: - platform: wunderground api_key: YOUR_API_KEY monitored_conditions: - alerts - dewpoint_c
(string)(Required)The API key for Weather Underground. See above for details.
(string)(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.yamlwill be used to display weather conditions.
(string)(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).
Default value: EN
(string)(Optional)Latitude coordinate to monitor weather of (required if longitude is specified).

All the conditions listed above will be updated every 5 minutes.
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
4 and valid values for daytime are
Conditions above marked with [1d] are daily forecasts. To get forecast for different day, replace the number
_1d_ part of the sensor name. Valid values are from
Conditions marked with [1h] are hourly forecasts. To get forecast for different hour, replace the number
_1h_ part of the sensor name with
weather_24h will give you weather in 24 hours.

Note: While the platform is called “wunderground” the sensors will show up in Home Assistant as “PWS” (eg: sensor.pws_weather).
Note that the Weather Underground sensor is added to the entity_registry, so second and subsequent Personal Weather Station ID (pws_id) will have their monitored conditions suffixed with an index number e.g.
