No this isn't something for your Raspberry Pi.
What this does is detects a potentially life-threatening electrical fault known as a broken neutral. It offers a potential solution to a problem that has challenged the electricity industry worldwide for decades. All you do is plug it into a power outlet and if it detects a fault will sound an alarm and turn red for an emergency and amber for high/low voltage.
CablePI is free to Tasmanian residential and small businesses customers.
