Energy Consumption Monitor Solar Energy Monitor Temperature And Humidity Monitor

Three Phase WiFi Energy Meter

Name: Three Phase WiFi Energy Meter
Brand: Beijing Lewei IOT Technologies Co., Ltd.

Overview

WEM3080T is a Din rail, there phase Wi-Fi Energy Meter/Wi-Fi Electricity Monitor. It can be easily installed and fit neatly inside your electricity panel, and provides insight into your energy consumption and analysis through our dedicated Online Energy Consumption Monitoring System (https://www.iammeter.com/) and Android/IOS app. With our cloud service, you can easily understand your electricity bill and get timely alert when the total energy consumption in a month reaches a preset value.

It is highly-integrated power meter with Wi-Fi module embedded, which can measure the data of specific electricity equipment, such as AC voltage and current of each phase, active power, total energy, and report them to the cloud every 5 minutes. You can directly get access to the its internal web server and easily set the Wi-Fi network configuration by one-key setup. With open data interface (Http get interface and Tcp Interface), the measurement data can be very flexible to stored locally or upload to your own server.
