From the brand
Why is my CT reading showing a negative value?
This issue may arise from incorrect wiring or settings. Fix it by inverting the current direction via the ‘Circuit Factor’ page in device settings; no need to physically alter the current transformer. Firmware update is required.
Can I monitor the net metering of my solar system?
Yes, Refoss EM16 can accurately monitor the net metering of your solar system.
Is the data being monitored accurate?
The energy monitor is rigorously calibrated to provide high-precision energy consumption data with an accuracy of 98%. For any questions, We’re here to help.
Is cloud data free?
Yes, Refoss offers free cloud services that can store historical consumption data for up to 3 years.
How to set up power consumption alerts?
In the Refoss app, click on the “Power Alert” option and customize the consumption threshold for each channel. The system will automatically notify you when the power consumption reaches the set value.
Can it be used with Home Assistant?
Yes, it is compatible with Home Assistant. After integration, you can monitor power consumption in real-time and set up automation scenarios directly from the Home Assistant dashboard.
✨NEW✨Feature Release (25.01): On the Device Settings -> Circuit Factor page, you can now invert the readings directly through the settings, eliminating the need to physically flip the current transformer. (Requires updating to the latest version of the Refoss app and firmware.)
Refoss Smart Home Energy Monitor: 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 in accessing the included current transformer and avoid bumping it to prevent 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.
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.
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.
Cut Electricity Costs and Maximize Efficiency: The energy meter accurately monitors solar panel and wind turbine energy generation, providing real-time data on power output. This allows you to optimize the use of renewable energy, enhance energy efficiency, and reduce electricity bills with ease.
