Sense ($300), Emporia Vue ($150), and Schneider Wiser ($600) lead the home-energy-monitor market in 2026. Sense identifies devices by power signature (no per-circuit sensors). Emporia uses per-circuit sensors for hard data. Wiser pairs with Square D panels for native integration. For most homes, Emporia Vue offers the best dollar-per-data-point. Sense is best for whole-home pattern recognition without per-circuit installation.

Brand-by-brand feature matrix

Sense ($300): 2 main current sensors. AI identifies individual devices over 4 to 8 weeks. Best for whole-home pattern recognition. 60 to 75 percent device identification accuracy.

Emporia Vue ($150 base + sensors): up to 16 per-circuit sensors. Hard data on each circuit. Manual configuration. Best for households with specific circuits to monitor.

Schneider Wiser ($600): integrates with Square D smart panels. Native circuit data. Premium fit-and-finish.

Install difficulty

Sense: 30 minutes inside breaker panel. Licensed electrician recommended. Emporia: 60-90 minutes for full 16-circuit install.

Wiser: only with Square D smart panel. Bundled install during panel upgrade. Highest fit-and-finish; highest cost.

Common questions

Quick answers from the editorial desk

How accurate is signature-based identification?
Sense: 60 to 75 percent device identification over 4 to 8 weeks. Some devices (LEDs, small electronics) below detection threshold. Per-circuit always 100 percent accurate.
240V circuit support?
Sense and Emporia both monitor 240V circuits with proper sensor configuration. Wiser tracks 240V natively via Square D integration.
Privacy concerns?
All three brands collect usage data to the cloud. Read privacy policies before signing up. Sense aggregates anonymized data for ML training.
Always-on vs battery monitors?
All three are always-on, powered by the panel. No batteries to replace. Data continues during grid outage as long as the panel has power (typically 0 if grid is down).
