EM114039 is a single-phase smart electricity meter, which supports LoRaWAN remote communication, has built-in relay, can realize remote control of relay on/off, and remote meter reading, It is widely used in smart cities and power distribution systems of the Internet of Things. The primary frequency band used for LoRaWAN in India is the IN865-867 MHz band. This falls within the license-exempt ISM (Industrial, Scientific, and Medical) band, which is crucial for cost-effective deployment as it doesn't require spectrum licensing.

4.What are the Key Considerations When Choosing a LoRaWAN DIN Rail Meter:
Phase: Single-phase or three-phase, depending on your electrical system.
Current Rating: Ensure the meter can handle the maximum current of your application.
Accuracy Class: Typically Class 1 or Class 0.5S for higher accuracy.
MID Certification: Essential if the meter is used for billing or legal metrology in Europe.
LoRaWAN Frequency Band: Ensure compatibility with your regional LoRaWAN network (e.g., EU868MHz, US915MHz, AS923MHz for Japan).
Antenna Type: Internal or external antenna options. External antennas can improve signal strength in challenging environments.
Additional Features: Look for features like multi-tariff metering, event recording, remote load control (via built-in relay), and local communication (e.g., RS485 Modbus) for parallel access.
Integration with Platforms: Consider how easily the meter can integrate with your existing or planned energy management system or IoT platform.
