The harvi is an essential part of the installation process if you want to save time and money. It has many great qualities including eliminating unsightly wiring around the home.

This intelligent device enables our products to be installed without using a hardwired current transformer. The harvi prevents the need to lift up floors and disrupt home decor. It’s patented technology is the only one of its kind, harvesting it’s own power from the CT clamps, removing the need for batteries or an external power supply.
