Useful for ignoring outliers from a faulty sensor for example.</p> <p>Both Deadband and Narrowband allow comparison against either the previous valid output value, thus ignoring any values out of range; or the previous input value, which resets the set point, thus allowing gradual drift (deadband), or a step change (narrowband).</p> <p><b>Note:</b> This works on a per <code>msg.topic</code> basis.
