Smart Home Energy Monitor with Real-Time Accurate Energy Consumption Tracking, Supports Home Assistant, Electricity Usage Monitor with Local Control, Open API & Web UI, Solar Metering, ETL Certified

Local Control & Privacy: Access your home energy monitor locally via Web UI, Open API, and MQTT without relying on cloud services. Integrate with Home Assistant or other platforms. Local data access protects your privacy while giving you full control of your home energy system.
Maximize Solar Energy: Designed for solar homes, the EM16P 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 Energy Monitoring & Cost Insights: Monitor voltage, current, active power, and power factor of major appliances. Provides ±1% accuracy (200A: 2200A; 60A: 160A) and ±2% at low current. Minute, hour, day, month, and year charts show real-time energy usage and electricity costs clearly. Daily data stored up to 5 years and exportable. Many users save 1020% on electricity bills.
Smart Alerts & Energy Control: Set usage targets for each 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.
ETL Certified & Reliable Performance: 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.
