The short answer

The Sense Energy Monitor is the best choice for homeowners who want appliance-detection (machine learning that identifies what's using power without any extra sensors). The Emporia Vue 3 is the best value choice — half the price of Sense with 16 physical circuit-level sensors included.

Where Sense wins

Sense's standout feature is its proprietary machine learning that identifies individual appliances by their electrical signatures. After a few weeks of training, the Sense app can tell you exactly how much power your fridge, dryer, well pump, and EV charger are using — without any additional sensors. The app is also the most polished in the category, with deep integrations into Alexa, Google Home, IFTTT, and Home Assistant.

Where Emporia Vue 3 wins

At half the price, the Emporia Vue 3 includes 16 circuit-level sensors in the box — meaning you can monitor 16 individual circuits directly, without needing ML appliance detection. For most homeowners, the Vue 3's direct per-circuit measurement is actually more reliable than Sense's ML-based detection. The Vue 3 also integrates natively with Emporia's smart plug ecosystem.

Decision framework

  • Choose Sense if: You want appliance detection without installing sensors on every circuit, or you want the best app experience and smart home integrations.
  • Choose Emporia Vue 3 if: You want the best value, or you prefer direct per-circuit measurement over ML-based detection.
