The `wunderground` platform uses [Weather Underground](http://www.wunderground.com) as a source for current weather information.
<p class='note warning'>
Obtain a WUnderground API key [here](https://www.wunderground.com/weather/api). A free account allows 500 requests per day and also a maximum of 10 per minute. See details [here](https://www.wunderground.com/weather/api/d/pricing.html).
</p>
To add Wunderground to your installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry

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](https://www.wunderground.com/weatherstation/ListStations.asp). 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](https://www.wunderground.com/weather/api/d/docs?d=language-support). If not specified, it defaults to English (EN).

### Forecasts
_12 hour forecasts_
Monitored conditions marked above with <a name="12h">[12h]</a> 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 <a name="1d">[1d]</a> 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 <a name="1h">[1h]</a> 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.

<p class='note warning'>
Note: While the platform is called “wunderground” the sensors will show up in Home Assistant as “PWS” (eg: sensor.pws_weather).
