Smart Home Energy Monitor, Native Open API & Web UI (No Cloud Required), Real Time Electricity Usage Monitor, Power Consumption Meter Works with Home Assistant & MQTT, Solar Net Metering, ETL

MAXIMIZE SOLAR & ZERO FEED-IN AUTOMATION: Designed for solar homes, the power monitor works with the Refoss app and Home Assistant to automatically use surplus solar power. Appliances like EV chargers, washing machines, and water heaters are powered during midday peaks, maximizing solar self-consumption and reducing low-value electricity feed-in to the grid. Optimizes usage and reduces bills.
REAL-TIME MONITORING & ±1% ACCURACY: Monitor voltage, current, active power, and power factor of major appliances.
Provides ±1% accuracy (200A: 2200A
; 60A: 160A) and ±2% at low current. Daily data stored up to 5 years and exportable. With no subscriptions or hidden fees, you get deep historical insights to help you identify every energy-saving opportunity and save 1020% on monthly bills.
SMART ALERTS & CIRCUIT-LEVEL CONTROL: Set usage targets for each individual circuit and receive instant alerts when appliances exceed normal consumption. Refoss app supports automation and peak management to optimize schedules, reduce peaks, and improve efficiency. Real-time electricity usage monitor for circuit-level insights.
ETL CERTIFIED & NON-INVASIVE INSTALLATION: ETL certified and compliant with UL 61010 safety standards for safe installation and operation. Supports 2 main circuit sensors (2200A each) and 16 branch sensors (160A each) with easy clamp-on installation. Fits most home circuit panels and includes a 2-year warranty with responsive support for reliable long-term monitoring.
