The `openweathermap` weather platform uses [OpenWeatherMap](https://openweathermap.org/) as a source for current meteorological data for your location.

There is currently support for the following device types within Home Assistant:

- [Sensor](#sensor)
- [Weather](#weather)

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

## Weather

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

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

{% configuration %}
api_key:
  description: Your API key for [OpenWeatherMap](https://openweathermap.org/).
  required: true
  type: string
name:
  description: Name to use in the frontend.
  required: false
  type: string
  default: OpenWeatherMap
