Overview

Sense Home Energy Monitor is a panel-installed monitor for U.S. and Canadian split-phase homes. It uses CT sensors on the service mains, a voltage reference from a 240 V breaker, and the Sense app/cloud platform to show real-time household energy use and detected device activity.

Measurement setup

The standard kit uses two main split-core current sensors around the service mains. Sense lists the sensors as CAT IV 250 V with a 200 A maximum rating. The middle port can accept one extra sensor pair for solar, generator, 400 A split-service, or dedicated-circuit monitoring.

Integrations

Sense connects over 2.4 GHz Wi-Fi. Home Assistant has an official Sense integration, but its IoT class is cloud polling, so this page marks Home Assistant support as true and local API support as false.

Buyer fit

Sense is strongest for app-led whole-home visibility and optional solar views. It is less suitable for buyers who need local-first data ownership, formal billing-grade accuracy, or many branch-circuit measurements.
