The `openweathermap` platform uses [OpenWeatherMap](http://openweathermap.org/) as a source for current meteorological data for your location. The `forecast` will show you the condition in 3 h. 

You need an API key which is free but requires a [registration](http://home.openweathermap.org/users/sign_up).

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

```yaml
# Example configuration.yaml entry
sensor:
  - platform: openweathermap
    api_key: YOUR_API_KEY
    monitored_conditions:
      - weather
```

{% configuration %}
