harvi is a smart little device that you use to communicate with zappi or eddi. This allows you to work without a wired CT clamp sensor. Instead, the CT clamp is connected to harvi, and zappi or eddi can measure the grid power (from your energy provider) or the self-produced power (from your solar panels or wind turbine). harvi does not require a separate power supply, as the energy generated by the CT clamp's magnetic coil is used to transmit the measured current signal to zappi or eddi. This means that no additional batteries or power cables are needed.
