InfluxDB Sensor
</h1>
</header>
<hr class="divider">
<p>The <code class="highlighter-rouge">influxdb</code> sensor allows you to use values from an <a href="https://influxdb.com/">InfluxDB</a> database to populate a sensor state. This can be use to present statistic about home_assistant sensors if used with the <code class="highlighter-rouge">influxdb</code> history component. It can also be used with an external data source.</p>
<p>To configure this sensor, you need to define the sensor connection variables and a list of queries to your <code class="highlighter-rouge">configuration.yaml</code> file. A sensor will be created for each query:</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">influxdb</span>
<span class="s">queries</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">name</span><span class="pi">:</span> <span class="s">mean value of foo</span>
<span class="s">where</span><span class="pi">:</span> <span class="s1">'</span><span class="s">"name"</span><span class="nv"> </span><span class="s">=</span><span class="nv"> </span><span class="s">'</span><span class="s1">'</span><span class="s">foo'</span><span class="s1">'</span><span class="s">'</span>
<span class="s">measurement</span><span class="pi">:</span> <span class="s1">'</span><span class="s">"°C"'</span>
</code></pre>
</div>
<p>Configuration variables for the server:</p>
<ul>
<li><strong>host</strong> (<em>Optional</em>): IP address of your database host, eg. 192.168.1.10. Defaults to <code class="highlighter-rouge">localhost</code>.</li>
<li><strong>port</strong> (<em>Optional</em>): Port to use. Defaults to 8086.</li>
<li><strong>username</strong> (<em>Optional</em>): The username of the database user.</li>
<li><strong>password</strong> (<em>Optional</em>): The password for the database user account.</li>
<li><strong>ssl</strong> (<em>Optional</em>): Use <code class="highlighter-rouge">https</code> instead of <code class="highlighter-rouge">http</code> to connect. Defaults to <code class="highlighter-rouge">false</code>.</li>
<li><strong>verify_ssl</strong> (<em>Optional</em>): Verify SSL certificate for <code class="highlighter-rouge">https</code> request. Defaults to <code class="highlighter-rouge">false</code>.</li>
<li><strong>queries</strong> array (<em>Required</em>): List of queries
<ul>
<li><strong>name</strong> (<em>Required</em>): The name of the sensor.</li>
<li><strong>unit_of_measurement</strong> (<em>Optional</em>): Defines the units of measurement of the sensor, if any.</li>
<li><strong>measurement</strong> (<em>Required</em>): Defines the measurement name in InfluxDB (the from clause of the query).</li>
<li><strong>where</strong> (<em>Required</em>): Defines the data selection clause (the where clause of the query).</li>
<li><strong>value_template</strong> (<em>Optional</em>): Defines a <a href="/topics/templating/">template</a> to extract a value from the payload.</li>
<li><strong>database</strong> (<em>Optional</em>): Name of the database to use. Defaults to <code class="highlighter-rouge">home_assistant</code>.</li>
<li><strong>group_function</strong> (<em>Optional</em>): The group function to be used. Defaults to <code class="highlighter-rouge">mean</code>.</li>
<li><strong>field</strong> (<em>Optional</em>): The field name to select. Defaults to value.</li>
</ul>
</li>
</ul>

<p>The example configuration entry bellow create two request to your local InfluxDB instance, one to the database <code class="highlighter-rouge">db1</code>, the other to <code class="highlighter-rouge">db2</code>:</p>
<ul>
<li><code class="highlighter-rouge">select last(value) as value from "°C" where "name" = "foo"</code></li>
<li><code class="highlighter-rouge">select min(tmp) as value from "%" where "entity_id" = ''salon'' and time &gt; now() - 1h</code></li>
