Verdict
The Emporia Vue 3 is a panel-level energy monitor: clamp-on sensors inside the breaker panel, reporting real power continuously to an app. The listing states UL Listing for the United States and Canada, support for single phase, single split phase and two wire systems, optional support for three wire and three phase four wire Wye systems with an additional 200 A sensor, solar and net metering monitoring, and a one year warranty. If you want to know where your electricity actually goes, including the hard wired loads a plug-in monitor cannot see, this is the category of device that answers it.

The Loads You Cannot Plug Into Anything
In most homes the largest consumers are hard wired: heating and cooling, an electric water heater, a cooker, a shower, lighting circuits, and increasingly an electric vehicle charge point. None of those can be measured by a plug-in monitor, which means a plug-in monitor tells you about the smaller share of your bill while the larger share stays invisible.
A panel monitor with per-circuit sensors sees all of it. That changes the conversation from “which appliance should we unplug” to “the heating is 60 percent of the bill and everything else is noise”, which is usually the truth and is usually a surprise.
Solar and Net Metering Are Where It Gets Interesting
With generation on the property, four numbers matter and they are easy to confuse: what you generate, what you consume, what you import and what you export. An inverter app shows generation. A utility bill shows import and export after the fact. Only a monitor watching both sides continuously shows self consumption, which is the number that determines whether shifting a load to the middle of the day is worth doing.
That is the practical value: you learn that running the dishwasher at two in the afternoon uses your own generation while running it at seven in the evening buys electricity, and the difference is visible rather than theoretical.
Be Honest About the Installation
This device goes inside a live electrical panel. Clamp-on sensors do not require breaking conductors, which is why the job is feasible at all, but the panel has to be opened and the sensors placed around conductors that are energised or have been isolated properly. That is qualified electrician work in most jurisdictions, and treating it as a DIY afternoon because the sensors are non-invasive is a mistake.
Check the system type before buying, too. The listing is specific: single phase, single split phase and two wire are supported directly; three wire and three phase four wire Wye need an extra sensor; Delta systems are not supported.
What to Do With the Data
- Establish a baseline first. A week of normal use tells you far more than an afternoon of switching things on and off.
- Find the standing load: what the house draws at three in the morning with nobody awake. That figure, multiplied by the year, is often the cheapest saving available.
- Compare circuits rather than chasing absolutes. The largest circuit is where attention belongs.
- Use our electricity cost calculator to convert a circuit’s weekly energy into a yearly cost at your tariff.
Strengths
- Sees hard wired loads that a plug-in monitor cannot.
- UL Listed, with the system types it supports stated clearly.
- Solar and net metering monitoring in the same device.
- Clamp-on sensors, so no conductors are broken.
Limitations
- Requires work inside a live panel, which means an electrician for most owners.
- Delta systems not supported, and some configurations need an extra sensor.
- App and account dependent, unlike a plug-in monitor with a screen.
- One year warranty is short for a permanently installed device.
How It Compares
The Kill A Watt P4400 answers one outlet with no installation and no account, and is the right first purchase for most people. The comparison between the two approaches is set out in plug-in versus whole home monitoring. Our ranking is in the how to choose a whole home energy monitor.

Frequently Asked Questions
What systems does it support?
The listing states single phase, single split phase and two wire systems. Three wire systems and three phase four wire Wye systems with earthed neutral are supported with an additional 200 A sensor sold separately, and Delta systems are not supported.
Does it need an electrician?
It installs inside the consumer unit or breaker panel with clamp-on sensors, which means opening a live panel. In most places that is work for a qualified electrician, and it is not a task to attempt on the strength of a video.
Can it monitor solar?
Yes. The listing states solar and net metering monitoring, which lets you separate what you generate from what you import and export.
Is it certified?
The listing states the Emporia Vue is UL Listed for the United States and Canada, and carries a one year warranty.
