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.
