Upgraded Watt Power Meter Plug Home Electrical Usage Monitor Consumption, Energy Voltage Amps Kill Tester with Backlight, Overload Protection, 7 Modes Display
Why we love it
Large, clear LCD display.
Tracks cumulative power usage.
Adjustable backlight duration.
Main highlights- Various Monitoring Parameters: The power meter plug can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days and time of your appliances. By switching 7 display modes, you can easily know the various parameters while the appliance is working. The home energy monitor can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time.
- Upgraded LCD display: With large screen size 2.36 inch x 1.85 inch, clearer monitor backlit, our electrical usage monitor can display the data clearer and more visible no matter day or night. 180°full wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers.
- Overload protection: When the power of the appliance exceeds the overload power, the LCD will display “OVERLOAD” to warn the user. All the buttons will quit working and can only be workable when you lower or remove the load power. The default overload power is 3680W and is adjustable from 0 to 3680W. In general, you need to set the overload power to 1800W before using. Just press the "function" button for more than 3 seconds to enter the setting.
- Monitor Your Energy Usage：Our watt meter power analyzer lets you track electricity consumption and manage power usage to help save on bills. It works as a voltage, kilowatt, current, and electricity meter. If you have any questions about your meter socket, feel free to contact us.
- Data Memory Function: The wattage meter will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. You can directly see the last data when you use it next time. This function can also automatically save the data when there is a sudden power failure.
- Adjustable Backlight Time: Our upgraded watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=always on), finally press the "COST" to save the backlight time settings.

Why we love it
Seamless integration with Home Assistant.
Monitors up to 18 circuits simultaneously.
Accurate real-time energy tracking.
Main highlights- NEW Feature Release (25.07.30): 1.Merge channels; 2.Export hourly-level energy data; 3.Manage Peak Demand; 4.Access the new energy statistics page; 5.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.
- 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.
- 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.
- 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.
- 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.
- 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.
