More features

• Comprehensive Home Energy Monitoring: Monitor your home’s real-time electricity usage with 2 main circuit sensors (up to 200A each) and 16 branch circuit sensors (up to 60A each). The easy clamp-on design supports single-phase 2-wire, split-phase 3-wire, and three-phase 4-wire Wye (TN or TT) systems (excluding Delta), making this home energy monitor ideal for smart energy management.
• Local Control & Privacy: Access your electricity usage through Web UI, Open API, and MQTT protocols without relying on the cloud. Integrate seamlessly with Home Assistant or other smart home platforms for local control. Local data storage ensures your energy data remains private while still supporting advanced home energy management and automation, allowing you to freely set automation rules and control every kWh of electricity usage.
• Smart Automation & Solar Zero Feed-In: Native Home Assistant integration and Refoss App automation allow you to automate, manage, and control your home’s real power. Surplus solar and net metering energy can be directed to medium-power appliances like heat pumps, dishwashers, and microwaves, while time-of-use and peak demand energy management ensures maximum solar self-consumption, prevents low-value grid feed-in, and reduces utility bills.
• Advanced Data Analytics & Smart Alerts: The EM16P smart power meter records minute, hourly, daily, weekly, monthly, and yearly energy usage, with daily data securely stored in the cloud for up to 5 years and fully exportable without any subscription. Receive smart alerts when appliances exceed normal consumption or peak usage, such as if a fridge or washing machine consumes unusually high energy, allowing you to promptly check or adjust usage habits. Detailed reporting helps households identify waste, optimize energy efficiency, and save 10%-20% on electricity costs.
• Real-Time Electricity Data: Provides 24/7 monitoring of voltage, current, active power, and power factor with ±1% accuracy (200A: 2–200A; 60A: 1–60A) and ±2% at low current. Track energy usage of kitchen ovens, water heaters, dryers, central AC, and EV chargers. Optimize energy consumption, save costs, and manage your home efficiently with this smart home energy meter.
• ETL Certified & Reliable Performance: ETL certified and compliant with UL 61010 safety standards for safe installation and reliable operation. Built with high-quality clamp-on CTs and backed by a 2-year warranty with customer support, it’s a dependable power consumption meter for long-term energy management.
