Harvi Wireless CT Sensor (excludes CT clamp)
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!
Up to three devices can be monitored by the Harvi. You will need to buy a Zappi, Eddi or separate CT clamp for the Harvi to work.
