Load Consumption Buzzer PowerAlert Integrated in Italian Residential LV Energy Communities

Residential housing is increasingly oriented toward all-electric consumption, also replacing gas loads. Users are under contract by an electricity provider that sets a power threshold above which the supplied is interrupted, that means it is increasingly difficult to stay below the threshold. The paper proposes an innovative device, called PowerAlert, that could show real-time power consumption with an audible signal related to the power thresholds set by the user. It is possible to switch the display between power consumption and the real-time clock with a simple push button. During device configuration is possible to connect it to a wireless network, to set a power meter among those available and its IP address. It is also possible to set three power thresholds referred to three different frequencies of the buzzer as alarm. This device can also be useful for monitoring modern electric devices that work in pulse mode and thermally stress protections that might intervene later.
