EM114039-01 LoRa Electricity Meter LoRaWAN Energy Meters Smart Home Power Meter

EM114039-01 is a single-phase smart electricity meter, which supports LoRaWAN communication, has built-in relay, can be connected with intelligent equipment, and can realize remote meter reading, remote control, etc. The meter has a visual LCD display, which can measure voltage, current, power, electricity quantity, frequency, power factor. The meter can be easily installed by using the guide rail installation method.

Product Details

1. Brief Introduction

EM114039 is -LoRa LoRaWan/LoRaMesh/Sigfox Multi-function Single Phase Wireless Digital Energy Meter for Long Distance communication. It has a built-in magnetic 80A latching relay and an SMA socket for an external antenna. LoRaWAN® network is a star-of-stars topology in which gateways relay messages between end-devices and a central network server. The gateways are connected to the network server via standard IP connections and act as a transparent bridge, simply converting RF packets to IP packets and vice versa. External interfaces provides pulse and LoRa wirless outputs, without any wiring , the user can easily read the data from the meter sand program the parameters of the meters. This solution makes the users out of trouble of wiring, and saves a lot of cost for lobor work and cables etc. The maintenence also become simple, the meter installation position can be changed within the communication area without any problem.

Lorawan wireless communication module combined inside the meter. With Lora gateway ESP, the user can remote monitor and program the meters. It saves lots of labor work for meter reading in sites with many meters, Bus line wiring and maintenance. by LoRaWAN, the communication distance between submeter to gateway can reach several kilometers. by LoRaMesh, data supports 4 relay hopping. The frequency band is 470Mhz. if other band is request, please specify when you order. 433, 869, 915Mhz are available.


(1)Simple din rail installation

(2)LoRaWAN Compliant

• EU 868 MHz ISM band communication

• US 915 MHz ISM band communication

LoRaWAN specification draw devices in three categories. All compatible devices must implement Class A with Class B and Class C as extensions to the specification of Class A devices.

Class A devices support bidirectional communication between a device and a gateway. Uplink messages (from the device to the server) can be sent at any time (randomly).

Class B devices extend class A by adding scheduled receive windows for downlink messages from the server. Using time-synchronized beacons transmitted by the gateway, the devices periodically open receive windows.

Class C devices extend class A can receive downlink all the time l End-device is constantly receiving. This allows for low-latency communication but is many times more energy consuming than Class A devices.

LoRaWAN is designed to wireless connect battery operated 'things' to the Internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.
