Both of these monitors do the same basic job: current-transformer clamps around your service mains, a box at the breaker panel, an app that shows what the whole house is drawing. The real split shows up after that. The Eyedro EYEFI-2 is a straight meter — accurate whole-home and solar totals, cloud software that's free forever, nothing clever. The Square D Wiser is the Sense machine-learning platform wearing Schneider Electric's badge: it tries to identify individual appliances from their electrical signatures, and you pay roughly a hundred dollars more for the attempt. That one sentence is most of the decision.
The picks
Eyedro EYEFI-2 — the meter
At $140–$180 it's the cheaper unit, and it carries the slightly higher rating of the pair (4.2 vs 4.0). It measures consumption or generation up to 200A/600V with two included sensors, connects over WiFi or Ethernet, and its directional sensing separates power you're pulling from the grid from power you're exporting — exactly what a net-metering solar household needs, with no add-ons. The MyEyedro platform costs nothing, ever. The trade: the interface is graphs and tables rather than a polished consumer app, and the base model reads the whole home, not individual circuits.

Square D Wiser — the detective
$250–$320 buys the same app and device-detection engine as a Sense monitor, sold under the Square D name that's been on breaker panels for decades. It fits most single-phase 120/240V panels up to 200A, ships with CTs, antenna, cables, and a mounting bracket, and ties into Alexa, Google, and Philips Hue. Solar takes the separate WISEREMPV variant or add-on CTs, so check which box you're ordering. Two catches are worth saying plainly: the appliance detection is the same slow, imperfect AI that Sense runs underneath, and the system is cloud-dependent with no local-only option.

The detection question, answered honestly
Appliance detection sounds like the obvious upgrade, so be clear-eyed about what it is. The software watches the electrical noise on your mains and guesses which device made it. That process takes time, some loads never get identified cleanly, and similar appliances get confused with each other — this is true of every monitor in the category, not a Wiser-specific flaw. When it works, it's genuinely useful: alerts for a device left on, confirmation the sump pump ran. If that's why you're buying, and you can live with the guesswork, the Wiser is the pick. If you'd resent paying a premium for a feature that's part magic trick, you already have your answer.
The quieter differences matter too. Eyedro's Ethernet jack is underrated — panels often sit in basements and garages where WiFi is weakest, and a wired link ends that problem. And "free software forever" versus "cloud-dependent" isn't just philosophy; one vendor's outage or policy change can't brick the Eyedro's core usefulness.
Who should skip which
Skip the Eyedro if the entire reason you want a monitor is "what's using all this power, specifically?" It will never tell you. That's by design, not a flaw. Skip the Wiser if you're a solar household on a budget — by the time you've bought the solar-capable version, the Eyedro has done the net-metering job for far less. And either way, installation happens inside the panel; if you're not comfortable there, price in an electrician before you compare price tags.
Bottom line
Most people should buy the Eyedro: it's cheaper, rated a touch higher, solar-ready out of the box, and free to run forever. Buy the Wiser only if appliance detection is the point and the Square D name settles your nerves — and go in knowing the AI is a patient, imperfect guesser.
