What is a IOT energy meter?

It is a meter that can measure electrical parameters and realize wireless communication.

How does a IOT energy meter work?

The meter upload the data of measurement to the IOT platform through wireless comunication like WIFI/4G.

How to choose which type IOT energy meter?

ADW2XX can measure 4 channels three phase energy meter, while ADW300 can directly upload data.

Why we recommend use iot energy meter?

IOT energy meter can connect to the iot platfom, which will let customer convient to monitor and management.

How Does A DW Series IOT Power Meter Work?

Acrel ADW Series IOT Energy Meter has two solutions to work. First, it can be connected to the gateway through RS485, and then the gateway uploads the data in the meter to the IOT cloud platform through 4G signal. The client can monitor the data in real time through PC or mobile APP. Solution 2 is ADW300 directly upload the data in the table to the IOT platform through 4G/WIFI signals, this solution does not need to pass through the gateway, more convenient installation.
