Problem is that Metrix (who are owned by Mercury) normally use the Elster Grex meters. They don't even have a blinking LED to indicate your current draw. Instead they have an icon on the same LCD screen that has the usage information on it. So alot harder to interface another device to.

 

 

There is always the CT sensor option which seems a lot easier thank counting blinks??
