<p class="note warning">
<strong>This platform has been deprecated in favor of the “<a href="/components/sensor.darksky/">darksky</a>” platform and will be removed in the future. Please use the “darksky” platform.</strong>
</p>
<p>The <code class="highlighter-rouge">forecast</code> platform uses the <a href="https://forecast.io/">Forecast.io</a> web service as a source of meteorological data for your location. The location is based on the <code class="highlighter-rouge">longitude</code> and <code class="highlighter-rouge">latitude</code> coordinates configured in your <code class="highlighter-rouge">configuration.yaml</code> 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 <a href="https://www.google.com/maps">Google Maps</a> and clicking on your home or <a href="http://www.openstreetmap.org/">Openstreetmap</a>.</p>
<p>You need an API key which is free but requires <a href="https://developer.forecast.io/register">registration</a>. You can make up to 1000 calls per day for free which means that you could make one approximately every 86 seconds.</p>
<p class="note warning">
<a href="https://forecast.io/">Forecast.io</a> will charge you $0.0001 per API call if you enter your credit card details and create more than 1000 calls per day.
</p>
<p>To add Forecast.io to your installation, add the following to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
