<h3>Details</h3>
<p>In RBE mode this node will block until the <code>msg.payload</code>,
(or selected property) value is different to the previous one. If required
it can ignore the intial value, so as not to send anything at start.</p>
<p>In the Deadband modes the incoming value must contain a parseable number and will block
unless the change is greater than + or - the band gap away from a previous value.</p>
<p>Deadband also supports % - only sends if the input differs by more than x% of the original value.</p>
<p>The Narrowband modes will block if the incoming value change is greater than + or - the band gap
away from the previous value. Useful for ignoring outliers from a faulty sensor for example.</p>

<p>The Narrowband modes will block the incoming value,

It is useful for ignoring outliers from a faulty sensor for example.</p>
<p>Both Deadband and Narrowband also supports % -
only sends if/unless the input differs by more than x% of the original value.</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
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. This means that a single rbe node can
handle multiple different topics at the same time.</p>
