Abstract

A system is provided in which a microcontroller is connected to a household unit, which is controlled by the microcontroller. The microcontroller is connected to wireless unit, so that the household unit may be controlled wirelessly (e.g. from a smart phone, tablet computer, laptop, and/or personal computer). In an embodiment, the household unit is a circuit breaker or a bank of circuit breakers that protect various devices in the house from faults in the power lines. In an embodiment, the household device is a switch, such as a solenoid for turning off an electrical appliance. In an embodiment, the household device has various settings that may be set remotely, via sending wireless signals to the microcontroller.
