 Works on numbers and strings. Useful for filtering out repeated messages of the
 same value. Saves bandwidth, etc...

+### Deadband modes
 
 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.
+It can also be set to block values more than a certain distance away from the present value.
+This can be used to remove outliers or unexpected readings. 
 
 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
