If you have a CurrentCost EnviR style energy monitoring device which can output data via USB. Then you can have data from that device uploaded by a server device (could be a Raspberry Pi) to a Xively online feed.This program will then access that Xively feed and show you your current consumption on your Android powered device.DO NOT INSTALL THIS APP UNLESS YOU HAVE AN ACTIVE XIVELY FEED CONTAINING VALID DATA.Example Upload script: http://pastebin.com/chHfPvmn
