Product Overview – harvi

It is important to note that harvi facilitates wireless communication between current transformer (CT) clamps and myenergi devices without the necessity for a wired power source or any physical connection.

harvi is an exceptionally innovative energy harvesting sensor developed by myenergi, specifically designed to streamline the installation processes of various systems, including zappi, eddi, and libbi. What sets harvi apart is its ability to draw power directly from the current transformers (CTs) it is connected to, effectively eliminating the need for traditional batteries or external power supplies. This unique feature not only simplifies the installation but also enhances the overall efficiency of the system.

This device is particularly well-suited for installations where the routing of additional cables would be impractical or could cause disruption. Its wireless capabilities mean that users can avoid the hassle and mess often associated with wiring, making it an ideal solution for various settings.
