The forecast platform uses the [Forecast.io](https://forecast.io/) web service as a source for meteorological data for your location. The location is based on the Longitude and Latitude cooridinates configured in `configuration.yaml`. The cooridinates are auto detected but to take advantage of the hyper-local weather reported by forecast.io, you can refine them down to your exact home address. GPS cooridinates can be found by using Google Maps and clicking on your home.

|
You need an API key which is free but requires a [registration](https://developer.forecast.io/register). You can make 1000 requests per day. This means that you could create one approximately every 1.4 minutes.
|
|
|
|
To add Forecast.io to your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|

Configuration variables:
|
|
|
|
- **api_key** (*Required*): Your API key for http://forecast.io/.

|
- **monitored_conditions** array (*Required*): Conditions to display in the frontend.
|
|
- **summary**: A human-readable text summary.
|
|
- **precip_type**: The type of precipitation occurring.
|
|
- **precip_intensity**: The average expected intensity of precipitation occurring.
|
|
- **temperature**: The current temperature.
|
|
- **dew_point**: The dew point.
|
|
- **wind_speed**: The wind speed.
|
|
- **wind_bearing**: Where the wind is coming from in degrees, with true north at 0° and progressing clockwise.
|
|
- **cloud_cover**: The percentage of sky occluded by clouds.
|
|
- **humidity**: The relative humidity.
|
|
- **pressure**: The sea-level air pressure in millibars.
|
|
- **visibility**: The average visibility.
|
|
- **ozone**: The columnar density of total atmospheric ozone in Dobson.
|
|
- **units** (*Optional*): Specify the unit system. Default to `si` or `us` based on the temperature preference in Home Assistant. Other options are `auto`, `us`, `si`, `ca`, and `uk2`.
|
