• AUDIT EVERY CENT & SLASH ELECTRIC BILLS: Stop the guesswork and start saving. By monitoring 18 individual circuits with professional ±1% precision, Refoss Home Energy Monitor shows exactly where your money goes. Identifying “energy vampires”—from HVACs to aging appliances—in real-time helps households effectively reduce monthly utility bills by 10%-20%. This smart power meter is the ultimate tool for electricity consumption audits.
• LOCAL PRIVACY & MULTI-PLATFORM CONTROL: Your home energy data belongs to you, not a cloud server. Featuring a built-in Local Web UI, Open API, and MQTT, and WebSocket, Refoss ensures 100% data privacy even without internet. Seamlessly integrate with Home Assistant (via Refoss_RPC) to manage every kWh without cloud reliance or subscription fees. Ideal for a secure electricity monitor with professional local control.
• SMART AUTOMATION & SOLAR ROI OPTIMIZATION: Turn your solar panels into a high-yield investment. 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.
• 5-YEAR DATA ANALYTICS & SMART FAULT ALERTS: Catch appliance failures early before they become expensive repairs. Refoss records minute/hourly/daily/weekly/monthly/yearly usage, with daily data securely stored for 5 years and fully exportable via CSV without any subscription. Receive smart alerts if a fridge or washer consumes unusually high energy, helping you optimize home power usage habits and prevent bill spikes.
• STABLE SIGNAL, EASY SETUP & PRO SPECS: This system supports Single-phase, Split-phase, and 3-phase 4-wire Wye systems, featuring 2 main sensors (up to 200A) and 16 branch sensors (up to 60A). ETL certified with a 2-year warranty, it includes an external high-gain antenna for enhanced Wi-Fi stability. Most importantly: if a sensor is installed backward, simply flip the reading in the App with one tap—no need to rewire or reopen the live breaker box.
