The `forecast` platform uses the [Forecast.io](https://forecast.io/) web service as a source of meteorological data for your location. The location is based on the `longitude` and `latitude` coordinates configured in your `configuration.yaml` file. The coordinates 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 coordinates can be found by using [Google Maps](https://www.google.com/maps) and clicking on your home or [Openstreetmap](http://www.openstreetmap.org/).
You need an API key which is free but requires [registration](https://developer.forecast.io/register). You can make up to 1000 calls per day for free which means that you could make one approximately every 86 seconds.
<p class='note warning'>
[Forecast.io](https://forecast.io/) will charge you $0.0001 per API call if you enter your credit card details and create more than 1000 calls per day.
</p>
To add Forecast.io to your installation, add the following to your `configuration.yaml` file:
```yaml
# Example configuration.yaml entry
sensor:
platform: forecast
api_key: YOUR_APP_KEY
monitored_conditions:
- summary
- icon
- nearest_storm_distance
- nearest_storm_bearing
- precip_type
- precip_intensity
- precip_probability
- temperature
- apparent_temperature
- dew_point
- wind_speed
- wind_bearing
- cloud_cover
- humidity
- pressure
- visibility
- ozone
- minutely_summary
- hourly_summary
- daily_summary
- temperature_max
- temperature_min
- apparent_temperature_max
- apparent_temperature_min
- precip_intensity_max
```
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 of the current conditions.
- **precip_type**: The type of precipitation occurring.
- **precip_intensity**: The average expected intensity of precipitation occurring.
- **precip_probability**: A value between 0 and 1 which is representing the probability of precipitation.
- **temperature**: The current temperature.
- **apparent_temperature**: A numerical value representing the apparent (or "feels like") 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.
- **minutely_summary**: A human-readable text summary for the next hour.
- **hourly_summary**: A human-readable text summary for the next 24 hours.
- **daily_summary**: A human-readable text summary for the next 7 days.
- **temperature_max**: Today's expected high temperature.
- **temperature_min**: Today's expected low temperature.
- **apparent_temperature_max**: Today's expected apparent high temperature.
- **apparent_temperature_min**: Today's expected apparent low temperature.
- **precip_intensity_max**: Today's expected maximum intensity of precipitation.
- **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`.
`auto` will let forecast.io decide the unit system based on location.
Details about the API are available in the [Forecast.io documentation](https://developer.forecast.io/docs/v2).
