IoT energy meter ,which is Internet of Things energy meter energy measurement device based on Internet of Things technology, which can monitor and record the use of electric energy in real time. With the maturity and stability of IoT communication technology and the increase of IOT communication methods, the development of IoT energy meter provides more communication options and broader function expansion conditions. IOT communication method is the way of communication between IoT devices or between IoT devices and the Internet, IoT energy meter is widely used in home, commercial and industrial fields, providing users with more convenient, efficient and safe power services.
Various IOT communication methods have their own characteristics and advantages, and are suitable for different application scenarios. Commonly used communication methods in IoT energy meters are Wi-Fi, Bluetooth, ZigBee, LoRa, Wi-Fine, PLC, NB-IoT, GPRS, etc..in scenarios where communication reliability is relatively high, two communication methods will be used at the same time for fault tolerance.

1. Wi-Fi communication IoT energy meter: Based on wireless local area network technology, it has high-speed and stable data transmission capabilities. It will be limited by the home Wi-Fi signal when used. Currently, it is relatively more used in the secondary market of energy meters. .
2. Bluetooth communication IoT energy meter: low power consumption, short-distance wireless communication technology, mostly used for data transmission between the energy meter and the indoor display.it is more convenient and real-time to view the electricity consumption data on the indoor display.
3. ZigBee communication IoT energy meter: a low-speed, low-power wireless communication protocol, which is a mode of LAN communication for IoT energy meter. ZigBee has a weak ability to penetrate walls and is currently used less on energy meters.
4. LoRa communication IoT energy meter: a long-distance, low-power wireless communication protocol, which is a mode of LAN communication of IoT energy meter.There are certain applications in energy meters.
5. PLC communication IoT energy meter: a way to use power lines for data transmission, which will not be affected by the installation environment, and is widely used in electric energy meters.
6, NB-IoT communication IoT energy meter: a narrowband Internet of Things technology, with low power consumption, low cost, wide area coverage and other advantages, with the development of CAT1 communication, NB-IoT in the field of energy meter gradually reduced.
7, GPRS (4G\5G): a high-speed, low-latency, high-reliability mobile communication technology, suitable for communication between IoT devices and the Internet, will have a huge impact on the future development of Internet of Things applications. It is used in three phase IoT energy meter and centralized controllers, and the utilization rate is increasing as the module price and tariff price decrease.
IoT energy meter realizes real-time monitoring and data acquisition of energy meter measurement data and meter status data, and sends commands to set parameters and remote control in real time. Improve the quality of power consumption management through data acquisition analysis and remote control and control, optimize power consumption schemes, and achieve energy saving and consumption reduction. The remote monitoring and management of IoT energy meters avoids human error and unnecessary human resource investment, and reduces costs. Realize data-based, intelligent and automated services, improve user experience, improve user satisfaction, bring new business models and business opportunities to the industry, and promote innovation and development.
