harvi – Energy harvesting wireless sensor

harvi is a clever little device that enables the zappi and eddi products to be installed without using a wired current transformer (CT) for measuring the grid and or generation power; instead the CT is connected to harvi. No power source is needed for harvi – the energy from the CT us harvested and used to transmit the measurement signal to the zappi or eddi. This means batteries or electrical wiring are eliminated!
