Both of these clamp onto the mains in your breaker panel and tell you what the house is drawing. The real split is granularity. The Emporia Vue 3 can directly measure up to 16 individual circuits, so the water heater, the HVAC, and the garage freezer each show up as their own line. The Eyedro EYEFI-2 measures the whole home — plus solar, with direction — and stops there. That one difference should drive the decision; price and app polish are secondary.
The two monitors
Emporia Vue 3 Smart Home Energy Monitor
Affordable, expandable monitor that directly measures up to 16 individual circuits with clamp sensors.

The Vue 3 runs $60–$160 depending on how many 50A circuit sensors you bundle in, and it's the value pick by a wide margin. Everything is directly measured — no algorithm guessing which appliance just kicked on — and the app and cloud storage are free, no subscription. It's UL Listed, needs 2.4GHz WiFi, claims accuracy around ±2%, handles solar net metering, and talks to Home Assistant if you'd rather not live entirely in Emporia's cloud. The honest downsides: the app is functional rather than pretty, sixteen clamps plus their leads get crowded fast in a tight panel, and the full feature set leans on the cloud.
Eyedro Home Energy Monitor (EYEFI-2)
Straightforward whole-home monitor with free lifetime cloud software and solar net-metering support.

The Eyedro is simpler on purpose. Two included sensors, rated to 200A/600V, tracking whole-home consumption or generation, with directional sensing so a net-metered solar home sees import and export as separate numbers. The MyEyedro platform is free with no subscription fee — real-time data, bill figures, reports, history, from any browser or phone. It also offers Ethernet alongside WiFi, which matters more than it sounds: panels tend to live in basement corners and behind metal covers, exactly where WiFi goes to die. What it doesn't do is break out individual circuits on the base model, and there's no AI appliance detection either. The interface is graphs-and-spreadsheets, not a slick consumer app. Expect $140–$180.
How to actually choose
Ask one question: when the bill spikes, do you want to know which breaker did it? If yes, buy the Vue 3 and stop reading. The Eyedro can tell you a spike happened and when; figuring out the culprit from a single whole-home graph is detective work — flipping breakers, watching the line move. Per-circuit sensors skip all that.
The Eyedro earns its spot in two situations. First, solar homes that mostly want clean import/export accounting — its directional sensing does that job well, and the free-for-life software means the math never acquires a monthly fee. Second, installs where WiFi near the panel is genuinely bad; an Ethernet jack solves what a stronger router sometimes can't.
Price cuts the other way. A base Vue 3 costs less than the Eyedro, and even a Vue 3 loaded with circuit sensors lands near the Eyedro's price while telling you far more. The ratings agree — 4.5 versus 4.2 — and that gap roughly matches the capability gap.
Who should skip both: anyone hoping a gadget will name their appliances without wiring anything. Neither of these does that — the Vue 3 needs a clamp on each circuit you care about, and the Eyedro doesn't try. Renters who can't open the panel are out too. And both installs mean working inside a live breaker panel; CT clamps are a quick job for an electrician and a bad afternoon for a nervous novice, so budget an hour of pro time if that's not your comfort zone.
Bottom line
The Vue 3 is the better buy for most people: cheaper to start, expandable to real per-circuit data, no subscription. Pick the Eyedro if whole-home totals plus solar accounting cover your needs and an Ethernet connection or the free-forever MyEyedro platform seals it. If you're on the fence, take the Vue 3 with a sensor bundle — circuit-level data is the whole reason to own one of these.
