Aim of this paper is to present a wireless monitoring smart system of household electrical facilities, with ZigBee/WiFi transceivers, able to detect absorbed current from electrical loads, to calculate dissipated power and energy by means of PIC-based software and to view, in real-time, calculated consumption values on web page properly realized for user’s remote control. Depending on light/presence sensors’ signal, the realized system can switch on/off the monitored electrical loads for obtaining energy saving and user satisfaction. Also by sending DALI-standard commands to slave loads (e.g lighting facilities based on LEDs), the user can monitor, remotely by using a tablet/smartphone connected to internet, the operation’s state and adjust the light intensity of each light point for achieving different scenarios. All functional tests, carried out on realized PCB prototype, have provided positive results allowing the use for the monitoring/driving of a real house’s electrical facilities.
