Energy harvesting wireless sensor harvi is an essential part of the installation process if you want to save time and money. It has many great qualities including the elimination of unsightly wiring around the home & prevents the need to lift up floor boards or disrupt home decor. This intelligent device enables the myenergi product family to be installed without using a hardwired current transformer.
harvi is a clever little device that enables the zappi and eddiproducts 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!
