<hr class="divider">
<p>The forecast platform uses the <a href="https://forecast.io/">Forecast.io</a> web service as a source for meteorological data for your location. The location is based on the Longitude and Latitude cooridinates configured in <code>configuration.yaml</code>. 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.</p>
<p>You need an API key which is free but requires a <a href="https://developer.forecast.io/register">registration</a>. You can make 1000 requests per day. This means that you could create approximately every 1.4 minute one.</p>
<p>To add Forecast.io to your installation, add the following to your <code>configuration.yaml</code> file:</p>
<pre><code class="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
</code></pre>
<p>Configuration variables:</p>
<ul>
<li><strong>api_key</strong> (<em>Required</em>): Your API key for <a href="http://forecast.io/.">http://forecast.io/.</a></li>
<li><strong>monitored_conditions</strong> array (<em>Required</em>): Conditions to display in the frontend.
<ul>
<li><strong>summary</strong>: A human-readable text summary.</li>
<li><strong>precip_type</strong>: The type of precipitation occurring.</li>
<li><strong>precip_intensity</strong>: The average expected intensity of precipitation occurring.</li>
<li><strong>temperature</strong>: The current temperature.</li>
<li><strong>dew_point</strong>: The dew point.</li>
<li><strong>wind_speed</strong>: The wind speed.</li>
<li><strong>wind_bearing</strong>: Where the wind is coming from in degrees, with true north at 0° and progressing clockwise.</li>
<li><strong>cloud_cover</strong>: The percentage of sky occluded by clouds.</li>
<li><strong>humidity</strong>: The relative humidity.</li>
<li><strong>pressure</strong>: The sea-level air pressure in millibars.</li>
<li><strong>visibility</strong>: The average visibility.</li>
<li><strong>ozone</strong>: The columnar density of total atmospheric ozone in Dobson.</li>
</ul>
</li>
<li><strong>units</strong> (<em>Optional</em>): Specify the unit system. Default to <code>si</code> or <code>us</code> based on the temperature preference in Home Assistant. Other options are auto, us, si, ca, and uk2.
<code>auto</code> will let forecast.io decide the unit system based on location.</li>
</ul>
<p>Details about the API are available in the <a href="https://developer.forecast.io/docs/v2">Forecast.io documentation</a>.</p>
