This parameter is used primarily for multi-x operations and controls what is the maximum time between incoming X10 signals before it is not considered part of a multi-x operation.

Sets the X10 status variables to ‘Unknown’ whenever PowerHome is started.  If cleared, PowerHome will use the last known status.

Enabling this parameter will cause the internal X10 status variables and Device Status screen to display ‘Unknown’ for status whenever a status request command is issued to an X10 device that supports status request.
