Complete Multi-Circuit Energy Monitoring – Starting at $349.99
Track detailed energy usage across your entire home or facility with our WiFi-enabled GreenEye Monitor, now bundled with a set of current transformers to suit a wide range of electrical loads.
Package Options:
Standard Package: Includes solid-core CTs – $349.99 + shipping & applicable taxes
Split-Core Package: Easier to install, no disconnection required – $379.99 + shipping & taxes
What’s Included:
- Comprehensive Monitoring: Monitor up to 32 breakers individually with our 32-channel WiFi GreenEye Monitor. Each channel can take multiple CTs, allowing you to group circuits together or monitor 240V loads.
- Versatile Current Transformers: The package includes 2 Split-200s (up to 200 Amps), 2 Micro-80s (40-80 Amps), and 18 Micro-40s (under 40 Amps) for a wide range of monitoring needs.
- Smallest Form Factor: Our Micro CTs are designed with the smallest form factor on the market, making them easy to install even in tight spaces.
- Advanced Connectivity: The ESP8266-based WiFi module with custom firmware seamlessly sends data to services like MQTT, with one-click Home Assistant MQTT discovery. Reprogram it with your own firmware for ultimate flexibility.
- Dual Network Capability: Optional Ethernet allows both Ethernet and WiFi to run simultaneously, sending data to different services.
Energy Monitoring Systems - How They Work

Sensors measure voltage and branch currents
- Current sensors are installed to each breaker wire in your circuit panel.
- Voltage is sensed using a specialized AC adapter.
- Measurements from the current and voltage sensors are used to determine “true” power and energy.
Measured data is forwarded to the Data Host
- The energy monitoring system is connected to your network (or directly to a computer).
- Configure to send to a data host of your choice.
- The data host interprets the incoming data and converts it into meaningful information.
*Data Host is any of the variety of services/software supported by our hardware.


The Data Host stores the data for viewing via Dashboards
View your consumption data on your data hosts dashboard.
- Figure out where your power is going.
- Find any “phantom power” being used while idle.
- Compare your appliance usage to new energy efficient appliances.
Use the data to reduce your power usage and save money.
