Monitoring and Configuring Individual CT Sensors or Phases in the Emporia Energy App
The Emporia Energy app offers versatile monitoring and configuration options for individual Current Transformer (CT) sensors, allowing users to analyze power consumption at both individual leg and combined mains levels. Below, we outline the steps for setting up CT sensors, viewing data, and optimizing configurations to enhance energy management.
Overview of CT Sensor Capabilities
The Emporia Energy app supports monitoring:
Combined mains usage: Total energy and power consumption measurements using 200A CT mains sensors.
Individual leg readings: Phases such as Main A or Main B can be analyzed by viewing amps or volts instead of combined kW or kWh data.
Exporting the Raw Data for Vue Monitors: the power per phase will be displayed. Columns labeled with suffixes like Main_A, Main_B, and Main_C indicate data from the device's "mains" sensors. These correspond to the three 200A CT sensor ports (A, B, C).
Configuring CT Sensors for Individual Leg Monitoring
If you want to monitor each leg individually without relying solely on total usage figures:
Modify the hardware setup: Use branch CT ports for the mains on your Emporia device. - Consider replacing the terminal blocks of your 2A CT sensors with aftermarket terminal blocks (e.g., options like those from DIGIKEY). This modification enhances customization.
Set ratios appropriately: When using branch ports with a 5A service, configure the circuit multiplier in the app's settings to maintain the correct measurement ratio (e.g., 4x for a 1:5 ratio setup).
Viewing and Analyzing CT Sensor Data
Combined Usage Data:
Open the Devices tab located in the bottom-right corner of the app.
Select the device tile displaying total energy usage.
The app will show combined net usage details, including production, solar, and battery metrics, if applicable.
Tips for Optimized Monitoring and Troubleshooting
Double-check Multipliers: Ensure that the multiplier settings in the app correspond to your service type and setup to avoid inaccuracies.
Hardware Modifications: When replacing terminal blocks or making other changes, consult the Emporia support team if needed, especially for warranty-related concerns.
Data Analysis: Regularly export CSV reports to track changes in individual CT readings and identify trends.
