8.Active upload / bidirectional transparent transmission function. Actively upload the data to the corresponding platform through the LoRaWAN wireless network, with a default interval of 4 hours (settable).
9.After the meter is powered on and the LoRaWAN module is connected to the network, the meter is automatically calibrated.


And our lorawan electricity can widely used in such scenarios:
a.Residential quarters: smart meter reading, energy-saving management, and prevention of energy waste.
b.Commercial places: saving costs, improving energy efficiency, real-time monitoring.
c.Industrial enterprises: precise measurement, remote monitoring, energy saving and emission reduction.
d.Government agencies: Unify management, reduce operating costs, and improve energy management levels.

Note

INSTALLTION
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.


TRANSPORTATION AND STORAGE
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.

Key Feature of LoRaWAN
LoRaWAN (Long Range Wide Area Network) smart electric meters bring several key features to the table, largely due to the specific advantages of the LoRaWAN communication technology itself. Here are some key features:

Long-Range Communication: LoRaWAN has a range of up to 15 kilometers in rural areas, and up to 5 kilometers in urban areas. This makes it perfect for smart meters, especially in areas where meters are spread out over large distances.

Low Power Consumption: LoRaWAN devices consume very little power, which means the smart meters can operate for years without needing a battery replacement. This is crucial in remote areas where regular maintenance may be impractical.

High Capacity: A single LoRaWAN gateway can handle up to thousands of nodes, meaning that a single gateway can receive data from thousands of smart electric meters, making it a cost-effective solution for large scale deployments.

Security: LoRaWAN uses two layers of encryption (unique network, application, and device keys) to ensure that the data being transmitted is secure. This is important in smart meters where privacy and security are key concerns.

Adaptability: LoRaWAN's Adaptive Data Rate (ADR) feature optimizes data rate, airtime, and energy consumption, making it suitable for varying network conditions.

Bi-Directional Communication: Unlike some other technologies, LoRaWAN allows for both uplink (device to server) and downlink (server to device) communications. This enables not just data collection, but also remote control or firmware updates if necessary.

Geolocation: LoRaWAN enables geolocation without additional power consumption, which can be beneficial in certain metering or grid applications.

Interoperability: LoRaWAN is based on open standards, which allows devices from different manufacturers to work together seamlessly. This is crucial for utilities companies who might have meters from different vendors.
