World Air Quality Index

</header>
<hr class="divider">
<p>The <code class="highlighter-rouge">waqi</code> sensor platform will query <a href="http://aqicn.org">World Air Quality Index</a> service to check AQI value for a specific set of locations. The resulting indexes will be added to the Home Assistant as sensor outputs.</p>
<p>This sensor requires an API token. Please obtain one at <a href="http://aqicn.org/data-platform/token/#/">AQICN API token</a>.</p>
<p>To enable this sensor, add the following lines to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
<span class="s">sensor</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">waqi</span>
<span class="s">token</span><span class="pi">:</span> <span class="s">AQICN_API_TOKEN</span>
<span class="s">locations</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">beijing</span>
<span class="s">stations</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">Beijing US Embassy</span>
</code></pre>
</div>
<p>Configuration variables:</p>
<ul>
<li><strong>locations</strong> (<em>Required</em>): A list of location names to look for air quality data. In case a specific location has multiple registered stations all of them will be added to Home Assistant.</li>
<li><strong>token</strong> (<em>Required</em>): The token for the AQICN public API.</li>
<li><strong>stations</strong> (<em>Optional</em>): A list of station names to look for air quality data. Station should be within locations specified above.</li>
</ul>
<p>The value reported is an overall AQ index for the location. The values of the index can be interpreted as following:</p>
<table>
<thead>
<tr>
<th>AQI</th>
<th style="text-align: center">Status</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td>0 - 50</td>
<td style="text-align: center"><strong>Good</strong></td>
<td>Air quality is considered satisfactory, and air pollution poses little or no risk</td>
</tr>
<tr>
<td>51 - 100</td>
<td style="text-align: center"><strong>Moderate</strong></td>
<td>Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution</td>
</tr>
<tr>
<td>101 - 150</td>
<td style="text-align: center"><strong>Unhealthy for Sensitive Groups</strong></td>
<td>Members of sensitive groups may experience health effects. The general public is not likely to be affected</td>
</tr>
<tr>
<td>151 - 200</td>
<td style="text-align: center"><strong>Unhealthy</strong></td>
<td>Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects</td>
</tr>
<tr>
<td>201 - 300</td>
<td style="text-align: center"><strong>Very unhealthy</strong></td>
<td>Health warnings of emergency conditions. The entire population is more likely to be affected</td>
</tr>
<tr>
<td>301+</td>
<td style="text-align: center"><strong>Hazardous</strong></td>
