Driven by the Internet of Things (IoT) trend in recent years, many cities have actively installed the Advanced Metering Infrastructure (AMI) system to replace the traditional mechanical meter.

Supervisors can monitor the users' usage in real time, and no longer need to calculate their billing by regularly dispatching staff to the site for the meter reading.
