. The majority of electric devices in households is stationary and — due to their considerable power consumption — relies on electrical installation, especially electric outlets instead of small electric generators, batteries, rechargeable or not. Due to their dependence on electric power sources, in general well-evolved power grids, electric devices and their power consumption pattern have moved into the focus of smart metering.
