Sense vs Emporia: Home Energy Monitors Compared

You cannot cut what you cannot see. A whole-home energy monitor lives in your breaker panel and shows exactly where your electricity goes, in real time. For years the two names in this space were Sense and the Emporia Vue. That changed at the end of 2025: Sense exited consumer sales on December 31, 2025, so its monitor is no longer available to buy new. The Emporia Vue 3 is now the default recommendation by a wide margin.

A quick safety note first: these install inside your electrical panel, which means working around live mains. If you are not comfortable with that, hire an electrician. It is a short job for a pro.

What they cost

• Emporia Vue 3: budget to mid-range, depending on whether you get 8 or 16 circuit sensors. Check current pricing before buying.
• Sense: no longer sold new to consumers after December 31, 2025. Existing units reportedly keep working, but we do not recommend buying into a discontinued product line.

How they measure your usage

Sense (discontinued for consumers) used two current sensors clamped around your main power lines, then applied machine learning to guess which device just turned on. It listens to the electrical "signature" of your fridge compressor, your dryer heating element, your coffee maker, and tries to label each one. When it works, it feels like magic: your phone tells you the garage freezer kicked on at 2 a.m.

The catch is the word "tries." Device detection takes weeks to build up, and some devices never get identified. Resistive heaters, variable-speed motors, and electronics with messy power signatures can stay anonymous forever. Sense keeps improving its models, but buyer reviews consistently say detection is partial, not complete.

Emporia Vue takes the dumber, more reliable route. Instead of guessing, it measures. You clamp small sensors around individual circuits in your panel (up to 16 with the Vue 3), so it knows exactly what the kitchen circuit, the HVAC circuit, and the water heater circuit are drawing. No guessing, no waiting for the algorithm to learn. What you see is what each circuit actually used.

The tradeoff: Emporia tells you about circuits, not devices. If your living room outlets, TV, and lamp share one circuit, Emporia shows one number. Sense, when it works, names the TV separately.

Accuracy and data

Both are accurate enough for household decisions. Emporia's per-circuit readings are generally within a couple percent of a utility meter. Sense's total usage reading is similarly close; it is the per-device breakdown where uncertainty creeps in.

Both offer real-time views in their apps, historical charts, and solar monitoring if you have panels. Emporia's app is straightforward and a little plain. Sense's app is prettier and its timeline view, showing devices switching on and off through the day, is genuinely fun to explore for the first month.

One practical difference: Emporia stores detailed history and offers integrations with home automation platforms that tinkerers like. Sense keeps things simpler and more consumer-friendly.

Installation

Sense is the easier install: two clamps on the mains, a power tap, and a Wi-Fi connection. Most handy homeowners finish in 30 minutes. Emporia's Vue 3 involves routing up to 16 small sensors through a crowded panel, which takes longer and demands more patience. Neither is hard in concept, but Emporia's install is fiddlier.

Both need a 2.4 GHz Wi-Fi signal that reaches the panel. Panels in basements and garages are often Wi-Fi dead zones, so test with your phone before you buy.

The quick comparison

Verdict by user type

Best overall: Emporia Vue 3. With Sense gone from the consumer market, this is the clear pick: direct per-circuit measurements rather than guesses, instant readings, solar monitoring, and a much lower price.

Best for the curious (used market only): Sense. Watching it name your appliances over the first month was satisfying, and the device timeline was the best in the business when detection cooperated. But buying a discontinued product means no warranty and an uncertain app future, so we do not recommend it.

Best for solar owners: Either works, but Emporia's lower price leaves more budget for the panels themselves. If you are shopping for a system, EnergySage lets you compare installer quotes side by side, which matters more than which monitor you pick.

Best for renters: Neither, honestly. Both need panel access you probably do not have. A few smart plugs with energy monitoring will tell you plenty about your biggest plug loads without touching the breaker box.

Whichever you choose, expect the same revelation every owner reports: something you never thought about is using far more power than you guessed. Usually it is the water heater, the dehumidifier, or an old second fridge. Finding it is the whole point.
