VOLTCRAFT SEM6500 BLACK Energy Cost Meter with Wireless Smart Plug, Data Logger, USB Export, Cost Forecast, TRMS, Adjustable Tariff VC-15450900

The VOLTCRAFT SEM6500 BLACK stands apart from typical plug-in energy meters by combining a precision TRMS measuring unit with a wireless smart plug, enabling both detailed consumption analysis and remote switching of connected appliances. Unlike basic meters that only show instantaneous values, this device logs up to 100,000 data points, calculates costs based on two adjustable tariffs, and exports everything to CSV via USB for long-term tracking.

Highlights

• True RMS measurement for accurate readings even with non-sinusoidal loads
• Includes a 433 MHz wireless smart plug for remote on/off control
• Data logger stores up to 100,000 measured values
• USB interface for CSV data export to a PC
• Cost forecast for daily, weekly, monthly, and yearly projections
• Two adjustable electricity tariffs (e.g., day/night)
• Large backlit LCD display for easy reading
• Integrated child protection and overload protection

In daily use

Plug the SEM6500 into a standard Schuko socket and connect your appliance to the smart plug. The meter immediately shows voltage, current, power, power factor, frequency, and cumulative energy consumption. Use the tariff settings to match your electricity contract, and the device will calculate running costs in real time. The wireless smart plug lets you switch the connected load on or off remotely, adding convenience and energy-saving potential. With the built-in data logger, you can record consumption over days or weeks, then transfer the data to a computer for detailed analysis.
