<p>The <code class="highlighter-rouge">min_max</code> sensor platform is consuming the state from other sensors and determine the minimum, maximum, and the mean of the collected states. The sensor will always show you the highest/lowest value which was received from your all monitored sensors. If you have spikes in your values, it’s recommended filter/equalize your values with a <a href="/components/sensor.statistics/">statistics sensor</a> first.</p>
<p>It’s an alternative to the <a href="/components/sensor.template/">template sensor</a>’s <code class="highlighter-rouge">value_template:</code> to get the average of multiple sensors.</p>

<p>Sensors with an unknown state will be ignored in the calculation. If the unit of measurement of the sensors differs, the <code class="highlighter-rouge">min_max</code> sensor will go to an error state where the value is <code class="highlighter-rouge">UNKNOWN</code> and the unit of measurement is <code class="highlighter-rouge">ERR</code>.</p>
<p>To enable the minimum/maximum sensor, add the following lines to your <code class="highlighter-rouge">configuration.yaml</code>:</p>
