Single Phase WiFi Energy Meter, Real Time Electric Meter/Monitor

Image
Introduction Single phase WiFi energy meter (WEM3080) is a Din rail, bi-directional, Wi-Fi energy meter/Wi-Fi electricity monitor. It is highly integrated power meter with Wi-Fi module embedded, which measures the data, such as single-phase AC voltage, current, power etc, and transmits them to cloud via WiFi network. smart meter wifi connection by one-key setup. With that, you can easily track, monitor and analyze your energy consumption in your home, company or factory in real-time. If you have a solar PV system, this meter can also help track the entire energy flow of the system. The system tells how much energy your solar system is producing, how much excessive energy are exporting to the grid or how much your loads are consuming from grid or your solar system. With open API, you can monitor the data locally via LAN or upload the data to your own server.
