@@ -18,6 +18,9 @@ Usage
A simple node to provide report by exception (RBE) and deadband function
- only passes on data if it has changed.
This works on a per **msg.topic** basis. This means that a single rbe node can
handle multiple topics at the same time.
###RBE mode
Outputs the **msg** if the **msg.payload** is different to the previous one.

In deadband mode the incoming payload should contain a parseable *number* and is
output only if greater than + or - the *band gap* away from the previous output.
Will accept numbers, or parseable strings like "18.4 C" or "$500"
The deadband value can be specified as a fixed number, or a percentage. E.g. 10
or 5% . If % mode is used then the output will only get sent if the input payload
value is equal or more than the specified % away from the previously sent value.
For example - if last sent value was 100, and deadband is set to 10% - a value
of 110 will pass - then the next value has to be 121 in order to pass (= 110 + 10% = 121).
This is mainly useful if you want to operate across multiple topics at the same
time that may have widely differing input ranges.
