✨NEW✨ Feature Release (25.07.30): 1.Merge channels; 2.Export hourly-level energy data; 3.Access the new energy statistics page; 4.Invert CT readings directly via Device Settings → Circuit Factor (no physical flipping needed!). Update to the latest Refoss app and firmware to enable all features. Refoss Smart Home Energy Monitor is ETL Certified and supports 2 main circuit sensors (up to 200A each) and 16 branch circuit sensors (up to 60A each) with an easy-to-install clamp-on design. Compatible with single-phase 2-wire systems, single-split phase 3-wire systems, and 3-phase 4-wire Wye systems with earthed (TN or TT) neutral (no Delta). Easily installs in most home circuit panels and includes a 2-year warranty. Attention: Take care when handling the included current transformers to avoid damage. 24/7 Energy Monitoring: With the Refoss app, you can track your home’s energy usage anytime, anywhere. Easily monitor the power, current, voltage, and power factor of major appliances like air conditioners, stoves, and water heaters. Quickly identify which devices are running efficiently and which ones might be wasting electricity. According to statistics, many users save an average of 10%-20% on their energy bills by optimizing appliance usage. Zero Feed In Automation: The EM16 is a smart meter designed for solar owners, linking with Home Assistant to automate your zero feed-in strategy. Ideal for homes with solar panels, it detects solar surplus (like midday sun peaks) and automatically powers high-energy appliances - such as activating your washing machine, EV charger, or water heater - to consume excess solar energy onsite. This prevents low-value electricity feed-ins to the grid, maximizing your solar investment returns and slashing utility bills. Comprehensive Energy Data: The power monitor provides 98% accuracy and stores up to 3 years of detailed electricity usage data. With clear minute, hour, day, month, and year consumption and cost charts, you can easily understand your energy use. Ideal for homeowners adjusting appliance usage to save on bills or businesses tracking long-term energy savings and emission reductions. Historical data can also be exported for further analysis, making every electricity expense transparent. Smart Consumption Alerts: You can set personalized usage targets for each circuit. Once the system detects an unusual energy spike—such as a sudden increase in power consumption by an appliance that exceeds the normal range—you will immediately receive a detailed alert notification. This allows you to take prompt action, such as checking if there is a malfunction with the device or adjusting your usage habits, thereby optimizing appliance usage across different times of the day. Compatible with Home Assistant: EM16 Wi-Fi Energy Monitor is now compatible with Home Assistant! Simply update the firmware in the Refoss app to seamlessly integrate your energy management system with your smart home platform, enabling centralized control and automation. Additionally, all data is stored locally, ensuring your privacy is protected without cloud processing. API is not supported.
