If you find that the Total (or Net) Usage readings from your Emporia Vue Gen 3 Energy Monitor are not aligning with your utility provider's measurements, you're not alone. Discrepancies can arise due to various reasons, including differences in billing timeframes, connectivity issues, and sensor configuration. Here are several key areas to investigate:
Time Frame Comparison:
Ensure you are comparing data from the same periods. Verify that the time zone setting on your device is correctly configured.
Please note that the Emporia Energy app utilizes a standardized billing cycle, which begins on the first day of each month. In contrast, your utility company may use different billing periods (such as March 11th through April 10th). This mismatch in timeframes can result in significant differences.
200A CT Installation:
Confirm that the 200A current transformers (CTs) are installed correctly. Accurate installation is crucial for precise readings.
Check for these common installation errors:
Incorrect Orientation: CT sensors must be installed with the arrow pointing towards the main breaker (away from incoming power).
Improper Wiring: The red and black wires from the CT harness must be connected to separate phases.
After correcting any installation issues, recalibrate the system through the Vue Settings menu.

Connectivity Issues:
Check for any connectivity problems that might be affecting data collection. The app requires consistent connectivity to the cloud and Wi-Fi to record accurate data.
Frequent disconnections can result in incomplete or inaccurate readings that don't match your utility bill.
Upstream Usage:
Check for any electrical usage occurring upstream from the energy monitor. This is particularly important if the Emporia data shows lower usage compared to the utility provider.
External breaker panels or power supplies upstream from the sensors can result in undetected usage.
Accuracy Expectations:
With properly installed CT sensors and correct cost per kWh settings, your Emporia readings should typically be within a margin of error of +/- 2% compared to your utility bill.
Contact Customer Support:
If the above steps do not resolve the discrepancy, reach out to our Customer Support team.
When contacting support, please provide the utility data you are comparing against and details about the installation and setup of your Emporia energy monitor. Including installation pictures can be very helpful.
Discrepancies between your energy monitor data and utility bills are often resolvable by addressing the factors above. By ensuring proper installation, checking connectivity, and comparing the correct timeframes, you can achieve more accurate energy monitoring and better understand your consumption patterns.
