The Milesight EG71 is an intelligent edge LoRaWAN BMS IoT gateway that unifies wired and wireless connectivity in a single device, simplifying data aggregation, protocol conversion, and local control for smart building integration across both new construction and retrofit projects.

Supports Python, Node-RED and Docker, enabling flexible secondary development for customized building logic, data processing, and system integration.

Control logic runs locally on the EG71, reducing latency and cloud dependency while ensuring stable operation during network interruptions. With multiple built-in I/O interfaces, EG71 can directly control field devices and actuators at the edge.

Features

A quad-core industrial-grade processor with large memory ensures stable performance for large-scale device connectivity and edge processing
Comprehensive I/O interfaces with native support for RS485, KNX, M-BUS (UnderDevelopment), LoRaWAN®, Wi-Fi, and Ethernet devices
Equipped with NFC for quick addition for add Milesight devices
Multiple backhaul options including Ethernet, cellular (4G) and Wi-Fi for reliable network redundancy
Supports mainstream protocols such as Modbus, BACnet, MQTT, and HTTP for seamless integration with third-party hardware or software
Provides secondary development capabilities (Python SDK, Node-RED and docker) to build customized BMS systems
Enables security communication with multiple VPN tunnels and firewall rules
Enables centralized and simplified remote device management via Milesight Development Platform
