CEEA™ vs. Square D Wiser: Circuit-Level Monitoring vs. Whole-Home Only
The Square D™ Wiser Energy Monitor (by Schneider Electric®) provides a view of overall household energy use by connecting CT sensors to the main service conductors. It’s a good step for basic insight, but it does not provide circuit-level detail. By contrast, the CEEA™ Professional Energy Monitor delivers up to 16 circuit-level channels (expandable), plus smart receptacle control, EV charger integration, solar tracking, and battery ESS support—all at a similar price point.
Core Difference: Detail vs. Whole-Home Only
- Wiser Energy: Measures energy flowing through the service mains. Provides a whole-home usage view, but no breakdown by branch circuit.[1]
- CEEA™ Professional: Uses up to 16 current transformers (CTs) for circuit-level monitoring. Lets you see which appliances or areas drive your consumption.
