This is the exact problem this Powerstrip can solve. You will be able to Monitor power consumed by each device plugged into the strip and Control them (turn them OFF) through your phone when they are not in use. You can also compare devices (Energy usage comparison) between devices of different brand.
Well there is no "App" for smart meters yet as utilities want to hold on to the data...they do not want to let you know how much you consume in real time. Also the People Power app and powerstrip will let you monitor each device's energy consumption and control the devices too. Also the current version PP1.0 currently only lets you monitor data for the entire house, but its a start. Soon you will be able to control your thermostats and devices through the app too, while measuring their power consumption individually.
