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). 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 may be disabled in the future.
|
|
</p>
|
|
|
|
To add Wunderground to your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# 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.

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).
|
|
- **latitude** (*Optional*): Latitude coordinate to monitor weather of (required if **longitude** is specified). Defaults to coordinates defined in your `configuration.yaml`.

### {% linkable_title 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).
|
|
</p>
|
|
|
|
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.
|
|
|
|
- sensor.pws_weather_1d_metric_2
|
|
|
