Single Phase WiFi Energy Meter

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

Overview

iMeter-WiFi (Single Phase) is a Din rail, Bidirectional, Wi-Fi Energy Meter/Wi-Fi Electricity Monitor. It is highly-integrated, single-phased power meter with Wi-Fi module embedded, which can measure and transmit the data of specific electricity equipments, such as single-phase AC voltage, current, power etc. It supports standard MODBUS-RTU protocol.

iMeter-W can be connected to our energy online monitoring system-Iammeter(https://www.iammeter.com/) by one-key setup. By using this product, you can easily monitor, analyze and save the energy consumption. With Cloud/App service, you can monitor it anytime from anywhere. With flexible function and open interface, you can monitor the data locally via LAN or upload the data to your own server.
