I am trying to use the Master Object For Parent setting on my router PING sensors...

For each location I would like to make the router PING sensor the MASTER OBJECT FOR PARENT with the idea that when the router is DOWN or OFFLINE any sensors that are for internal devices past the router will be paused.

This will prevent a huge flood of alerts from all the internal devices past the router. But if any single sensor for an internal device past the router goes DOWN then the alerts for that one sensor will come through.

In order to make this work is setting the router PING sensor as MASTER OBJECT FOR PARENT the best way to do it?

Also if setting the router PING sensor as MASTER OBJECT FOR PARENT is the best way to do it do I need to select a DEPENDENCY for the router PING sensor itself and do I need to select a DEPENDENCY for the other device sensors past the router?
