MYENERGI Harvi Self-Powered Wireless CT Sensor

myenergi harvi Energy Harvesting Wireless Sensor

The myenergi harvi is a wireless power sensor designed to work with zappi and eddi, enabling energy monitoring without a wired connection between the current transformer (CT) clamps and the myenergi device. Using patented energy harvesting technology, it draws power directly from the CT clamps, removing the need for batteries or an external power supply.

Featuring three CT inputs, harvi supports single-phase, three-phase or multi-point power measurement, with configurable monitoring of grid, generation or storage. Its compact, wall-mountable design provides installation flexibility while reducing cable runs and disruption to existing floors and home décor. CT clamps are supplied separately.
