+  <li><strong>tolerance</strong> (<em>Optional</em>): Set a minimum amount of difference between the temperature read by the sensor specified in the <em>target_sensor</em> option and the target temperature that must change prior to being switched either off or on. For example, if the target temperature is 25 and the tolerance is 0.5 the heater will start when the sensor goes below 24.5 and it will stop when the sensor goes above 25.5.</li>
