Home Energy Wizard (HEW) Energy Monitor is a real-time electricity monitoring device that needs to be professionally installed (by an electrician) into the residential (or small commercial) customer mains switchboard. 

Once installed, the device will continuously stream key electrical quantities (like energy consumption, supply voltage, electric current, power factor, etc.) to a bluetooth-enabled IOS or Android device running the HEW Energy Monitor App, helping customers understand their energy needs.
