If your Unmonitored usage is unusually high or showing green (negative), or solar net metering isn't tracking right, this article covers both because they can share the same root causes. Most issues come down to: a sensor reversed, a phase mixed, a multiplier in the wrong place, or a calibration that needs to be re-run.
Name change: In the app’s circuit list, Unmonitored was previously labeled Balance. It’s the same measurement: Mains Total minus the sum of Branch Circuits 1–16.
Quick Guide: What's the Symptom?
Unmonitored value is much higher than expected → jump to High Unmonitored Usage.
Unmonitored usage is showing green (negative) → jump to Green or Negative Unmonitored Usage.
Solar isn't showing as Net Production → jump to Solar / Net Metering Wrong.
Total doesn't match my utility bill → see Main CT Total Usage Doesn't Match Utility Bill in Incorrect CT Sensor Readings.
What "Unmonitored" Usage Is
In the Emporia app, Unmonitored appears at the bottom of your Vue’s circuit list. It’s the difference between your whole-home Total (from the 200A main CTs) and the sum of your individual branch readings (from the 50A CTs):
Unmonitored = Mains Total − Sum of Branch Circuits 1–16
In a normal home, Unmonitored usage is positive and represents the energy used by circuits you don’t have a 50A CT on (lighting, outlets, miscellaneous loads). When it looks off, it usually means a sensor is reversed, missing, or counted twice.
High Unmonitored Usage
A higher-than-expected Unmonitored value most commonly comes from one of:
Missing 50A CTs. Open the circuit list in the Emporia app and confirm every sensor you've installed is showing up. If one is missing, see Incorrect CT Sensor Readings.
Big circuits not yet monitored. If your dryer, EV charger, or HVAC don't have 50A CT sensors on them, their consumption rolls into the Unmonitored row. Adding sensors to those circuits is the cleanest fix.
Mains over-counting. Confirm you have the right number of 200A CTs — one per live phase, no more. Compare your Total to your utility bill: if it's more than ±2% off, the mains are likely the issue. See Main CT Total Usage Doesn't Match Utility Bill.
Multipliers on lightly-loaded circuits. A 2.0× multiplier on a circuit with imbalanced legs can over- or under-state usage and skew Unmonitored usage. Where possible, use two sensors and Circuit Merging instead (see Merging and Unmerging Circuits).
Don't try to allocate Unmonitored usage manually. A high Unmonitored value is a signal that something needs troubleshooting — it's not a number to spread proportionally across your monitored circuits. Manually distributing the unmeasured energy will hide the real cause and make your data less accurate, not more.
Green or Negative Unmonitored Usage
A green Unmonitored value means the sum of your branch circuits is greater than your Mains Total. That doesn’t automatically mean something is wrong. Common causes:
Solar generation that isn't flagged. If you have solar but no 50A CT on the solar circuit (or it's not configured as a Solar/Bidirectional circuit), the device under-counts mains relative to branch totals.
200A mains under-counting. Missing a 200A CT on one phase, or a CT that's reversed or mis-calibrated, makes the mains read low.
50A CTs over-counting. Common causes: a sensor on a neutral line that shouldn't be, two sensors on the same wire counted as separate circuits, or a multiplier set higher than the actual ratio.
If the Unmonitored row continues to show green or negative after these checks, run the recalibration flow with the correct Solar/Generation selection. See Resetting Your Vue: Wi-Fi, Solar, and Recalibration.
Solar / Net Metering Wrong
If your home has solar and your Vue isn't tracking generation correctly, the issue is one of three things:
Issue 1 — Vue isn't flagged for solar. If the top of your circuit list shows Total Usage but never Net Production, the Vue was set up as no-solar. Run the recalibration flow and select 'Yes' when asked if your system generates its own energy. See Resetting Your Vue: Wi-Fi, Solar, and Recalibration.
Issue 2 — 200A CTs in the wrong place. The 200A mains CTs must sit between the incoming grid power and the solar inverter's connection point, not downstream of the solar tie-in. If solar is connected to the mains directly (rather than through a breaker in the same panel as the Vue), the mains CTs may not see the bidirectional flow. If you're not sure, photograph your install and send it to Customer Support for a sanity check.
Issue 3 — Calibration needs to lock onto the correct phase voltages with solar present. Run the recalibration flow with these conditions:
Turn off solar generation during the reset (cover the panels, flip the solar disconnect, or run after dark). The Vue assumes any current it sees is grid-supplied during calibration.
Run as much consumption as you can during the reset (HVAC, water heater, dryer). At least 1 kW per phase helps the calibration lock in correctly.
Select 'Yes' when asked if your system generates its own energy.
After a successful recalibration, generation appears as green/negative numbers and consumption appears as blue/positive numbers. Net Production at the top of the circuit list will swap to Net Usage when consumption exceeds generation.
If You're Still Stuck
Measurement-accuracy issues can be tricky — the symptom is rarely far from the cause but the cause itself can be subtle. Please contact our Customer Support team with:
Photos of your panel showing the CT placements and the wire harness routing.
Your Total Usage / Net Production reading for a recent full billing period.
A screenshot of your circuit list showing the Unmonitored row.
Whether you have solar, battery, or other generation, and how it's connected to your panel (such as a line diagram).
For Persistent Issues, Consult an Electrician
If you've worked through the checks above and your numbers still aren't where they should be, a licensed electrician can verify your panel's actual wiring and confirm phase assignments. The Vue can only report on what it's measuring — if the panel itself is wired in an unusual way, on-site eyes are the fastest path to a fix.
