DTSY866/DSSY866 Three phase electronic prepaid Bluetooth energy meter (Scan QR code on mobile phone to recharge prepaid rental room card insertion app, self-service payment for electricity meter)

Product Overview

This product adopts an advanced microcontroller processing system for data acquisition, processing, and storage. It adds Bluetooth communication function on the basis of traditional IC prepaid electricity meters, and connects with mobile phones through Bluetooth communication to achieve the function of mobile phone prepaid electricity bills. Simultaneously characterized by high precision, high reliability, high overload, and low self power consumption, the backend system interface design is simpleClean and beautiful, easy to operate process, user-friendly, perfect solution to the difficulty of collecting electricity bills from landlords, suitable for scenarios such as apartments, property management, parks, campuses, etc. The main functions are as follows:

• Online collection: The landlord adds a WeChat Alipay collection account through the WeChat applet, and the tenant directly arrives at the account bound to the landlord after paying the electricity bill;

• Online payment: tenants can pay online by scanning the QR code of the meter, and support WeChat Alipay dual platforms (Bluetooth communication is 10 meters away from obstacles);

• Automatic closing: When the balance of the electricity meter recharge is "0", the system automatically closes the switch. Landlords can also connect via WeChat mini program and BluetoothelectricityRemote closing of the switch behind the watch.
