The Wire Harness acts as the vital link for the Vue 3, enabling it to connect seamlessly with four uniquely purposed wires. This integral part ensures the device is both powered and capable of performing detailed electrical measurements within your home.
The Wire Harness component is similar in function to the Vue 2 device, although the connector is a bit different:
Wire Functions
Black Wire: Powers the Vue device and monitors one phase of voltage
Red & Blue Wires: Installation locations vary based on your electrical system
White Wire: Serves as the neutral line, typically connected to the neutral bus bar
An exception to this would be an AFCI/GFCI or RCD breaker. For installations involving these breakers, please refer to the instructions found here
Installation Based on System Type
Single Phase (one live main): Black to live breaker; Red/Blue/White to neutral bus bar
Split Single-Phase (two live mains): Black and Red to live breakers on separate phases; Blue/White to neutral bus bar
Three Phase (three live mains): Black/Red/Blue to live breakers on separate phases; White to neutral bus bar
Calibrating the device:
When first installed, the device calibrates automatically. If you adjust the wire harness after setup, you'll want to re-calibrate the device to ensure that any physical changes to the hardware installation are captured. To run a re-calibration reset, you'll want to follow these steps:
Open the Emporia Energy app
Go to Menu (☰) → Manage Devices
Select your device
Scroll down and select "Reset WiFi / Solar Setup"
Follow the prompts to complete the recalibration
