About harvi

 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 is harvested and used to transmit the measurement signal to the zappi or eddi. This means batteries or electrical wiring are eliminated!


    • Wireless power sensor
    • Energy harvesting – no batteries or electrical wiring


    • Uses standard CTs supplied with eddi & zappi


    • 3 CT inputs for 3-phase supplies
    • Grid / Generation / Storage measurement configurable
    • Fast & accurate measurement
    • Wall mountable
    • Please note* harvi doesn’t come with it’s own CT

    Really helpful company, easy to deal with, no pressure selling and seem to know everything when it comes to heat pumps. They explained everything we needed and how it would work simply for us to understand.

    We have just had our boiler replaced with a Cool Energy invertech heat pump. From initial enquiry through to recommending a local installer, we cant fault the service. The heat pump is very quiet and so far seems very efficient to run. Very happy!
