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.
Side-by-side comparison
| Feature | Sense Energy Monitor | Emporia Vue 3 |
|---|---|---|
| Price | ~$299 | ~$149 |
| Circuit-level sensors | 2 mains + 2 solar (expandable to 18 with Flex Add-On) | 2 mains + 16 branch circuits (included) |
| Appliance detection | Yes (ML-based, no extra sensors needed) | No (must install CT on each circuit) |
| Solar tracking | Yes (native, includes solar CTs) | Yes (native) |
| Smart home integrations | Alexa, Google, HomeKit, Home Assistant, IFTTT | Alexa, Google, Home Assistant |
| App quality | Best in class | Good |
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.
