Usage
|
|
-----
|
|
|
|
A simple node to provide report by exception (RBE) and deadband function
|
|
- only passes on data if it has changed.
|
|
|
|
###RBE mode
|
|
|
|
Outputs the **msg** if the **msg.payload** is different to the previous one.
|
|
Works on numbers and strings. Useful for filtering out repeated messages of the
|
|
same value. Saves bandwidth, etc...
|
|
|
|
###Deadband mode
|
|
|
|
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"
