I was just replying to your previous post, glad to see things are working.
If you are talking about the “Configure” button 
, that updates the configuration of the device (it is a little useless since that gets called when you edit the preferences). I guess I should remove it. 
I think people have used the “Better Laundry Monitor” app with this device type. I use the app I wrote “Yet Another Power Monitor” with my device type. It is essentially the same thing but I don’t have the extra bells and whistles @sudarkoff put in his app.
So there is a concept of “All switches on” where a group of different devices all perform in unison (like synchronized swimmers). This controls the behavior when this device is added to one of those groups. I don’t think SmartThings supports this feature yet but they might when you group devices in Rooms.
