DDSY866 Single-phase electronic energy meter (Mobile Bluetooth Scan Code - Wireless 4G Remote Prepaid)

Product Overview

This product adopts an advanced microcontroller processing system for data collection, processing, and storage. It adds 4G communication and Bluetooth communication functions on the basis of traditional IC prepaid electricity meters. It communicates with the base station through the operator's 4G network and uploads it to the cloud server to achieve remote communication, remote meter reading, remote power on/off, and mobile prepayment of electricity bills. In the case of unstable 4G network, you can immediately switch to Bluetooth mode to achieve Bluetooth meter reading and Bluetooth recharge in a timely manner. At the same time, the 4G+Bluetooth dual-mode meter has the characteristics of high precision, high reliability, high overload, low self power consumption, and complementary communication advantages. The backend system interface design is simple and beautiful, the process operation is convenient, and users are easy to use, perfectly solving the difficulty of landlord electricity collection. It is suitable for scenarios such as apartments, property management, parks, and campuses. The main functions are as follows:

• 1) Online collection: landlords add WeChat and Alipay collection accounts through WeChat applet, or bind corporate bank card accounts through PC computer terminals, and tenants directly arrive at the landlords' collection accounts after paying electricity bills;

• 2) Online payment: tenants can make online payment by scanning the meter QR code or sharing the QR code with the landlord, and support WeChat Alipay dual platforms (unlimited distance in 4G mode; Under Bluetooth mode, there are no obstacles within 10 meters;

• 3) Remote closing: When the remaining power of the meter is "0", the system automatically closes the switch. Administrators can forcibly turn on and off the electricity meter when there is remaining power.

• 4) Automatic meter reading: When there is a signal, the software end of the meter will refresh the electricity level on the homepage every 30 minutes. Back end meter reading records, saving one record per day.
