Welcome to our online shop!

The Greenio shop is all about eco-friendly products. We like to stock anything green, recycled, and rechargeable (with solar, of course). There is a purpose behind every item, where some will donate a percentage to clean water products or for the planting of trees, some are just looking at replacing the plastic alternative.

There isn’t really a limit to the eco-products we will stock, so if you think there is something that our shop needs, then please feel free to get in touch!

Harvi - Wireless Interface

In stock
Product Details

Harvi is a clever little device that enables the zappi and eddi products 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!


• Wireless power sensor
• Energy harvesting – no batteries or electrical wiring required
• Uses standard CTs supplied with eddi & zappi products
• 3 CT inputs for 3-phase supplies
• Grid / Generation / Storage measurement configurable
• Fast & accurate measurement
• Wall mountable
