What exactly does a smart meter do?

Smart meters are not only widely used in homes and businesses, but also can improve the efficiency and safety of electricity management through a variety of functions.

‌Smart meters have a variety of uses and functions, mainly including the following aspects‌:

‌Real-time monitoring and remote control‌: Smart meters can monitor home or business electricity consumption in real time. Through mobile phone APP or other terminal devices, users can remotely control home electrical appliances anytime and anywhere, such as turning off and turning on lights, etc.

Safety protection‌: Smart meters have functions such as overload protection and short-circuit protection, which can effectively avoid safety accidents caused by improper electricity use. In addition, smart meters can also monitor the power consumption status of electrical equipment in real time, and alarm in time when abnormal power consumption is found.

Energy saving and environmental protection‌: Smart meters can automatically adjust the power supply voltage and current according to the power consumption of electrical equipment to avoid unnecessary energy waste. At the same time, smart meters can also provide users with electricity usage suggestions to help users develop energy-saving and environmentally friendly living habits.

‌Convenient and fast‌: Smart meters do not require manual meter reading, and can automatically record and count electricity consumption data. Users can check electricity usage information through mobile phone APP or website, which is convenient and fast.

‌Prepayment function‌: Smart meters can collect electricity bills in advance to prevent power outages due to insufficient balance. At the same time, smart meters can also issue alarms to remind users to pay on time.

‌Accurate billing‌: Smart meters can accurately measure electricity, detect the flow of wiring boards and sockets, and ensure the accuracy of billing.

‌Memory function‌: Smart meters have powerful memory functions, and can save data in the meter even when the power is off to ensure the integrity of user information.

Electricity theft monitoring‌: Smart energy meters have the function of automatically investigating and handling electricity theft, and prevent criminals from stealing electricity through external meter boxes, meter cases, and meter terminal seals.

‌Two-way data communication‌: Smart meters support multiple data transmission modes, such as wireless communication or optical fiber networks, and can measure electricity, open and close electricity, and operate home appliances remotely.

Advanced Metering Infrastructure (AMI) and Automatic Meter Reading (AMR) Systems: AMI and AMR systems built on smart meters can provide users with detailed electricity usage information, helping them better manage electricity usage, save electricity bills and reduce greenhouse gas emissions.
