Harvi wireless sensor for Zappi, Eddi, and Libbi

myenergi harvi — wireless energy sensor

The Harvi is myenergi’s wireless energy sensor. It transmits measurement data from your CT sensor wirelessly to your Zappi, Eddi, or Libbi—without running cables to your meter cabinet and without batteries. That makes installation a lot easier.

Measuring without cables or batteries

The Harvi is unique because it generates its own power from the CT sensor. So it doesn't need a power supply or a battery; you never have to charge it or replace it. Just place it near the meter, and it does the rest.

When should you choose a Harvi?

The Harvi is the solution when it's difficult to run a CT cable back to your MyEnergi device, for example:

1. The meter box is far from your Zappi, Eddi, or Libbi.
2. You don't want any additional wiring in an existing installation.
3. In a 3-phase system, three measurements must be transmitted wirelessly.

Up to 3 CTs, for single-phase and three-phase systems

A single Harvi can process up to three CT sensors at the same time. This allows it to cover both single-phase and three-phase installations, and it can measure your power generation in addition to your grid consumption.

Works with the entire myenergi ecosystem

The Harvi connects wirelessly to your Zappi, Eddi, Eddi+, and Libbi via the secure myenergi protocol. This way, your entire system knows exactly how much energy you’re generating and consuming, and each device intelligently manages your excess solar energy.

Benefits of the Harvi

1. No cables to the meter box and no batteries required.
2. Harvest its own energy from the CT sensor.
3. Rated for up to 3 CTs, for single-phase and three-phase systems.
4. Makes retrofit installations simple and neat.
5. Seamless integration with Zappi, Eddi, and Libbi.

Frequently Asked Questions
