Structural analysis of the Fusion Energy Monitor confirms a high-density telemetry design utilizing 16 non-invasive Current Transformers (CTs). These induction sensors are engineered to measure magnetic fields around individual circuit conductors with a ±2% tolerance for 50A branch circuits. The main logic board is based on an ESP32 microcontroller, facilitating 1-second interval data reporting via a 2.4GHz Wi-Fi stack.
Installation data specifies that the system requires physical integration into a main breaker panel, with revenue-grade accuracy of 0.5% verified for the main lugs. To maintain signal integrity through metal enclosures, an external antenna must be deployed via a knockout hole, as internal RSSI values frequently exceed -75dBm when shielded by the panel door.
- Telemetry Depth: 1-second interval granular reporting.
- Sensor Capacity: 16 individual circuit monitoring channels.
- Integration: Local API support via ESPHome and Home Assistant.
Summary: This unit provides detailed sub-metering of residential loads without a mandatory subscription fee. Technical limitations include significant wire clutter within the breaker panel and a lack of support for 5GHz wireless bands, which may impact data throughput in high-interference environments.
The Ecobee Smart Bundle is a recommended alternative for users seeking a consumer-facing environmental control suite rather than industrial-grade electrical sub-metering.
