Solution B : Siemens Building X - Milesight LoRaWAN sensor Integration via Siemens Connect Gateways

TABLE OF CONTENTS


Preface

This guide describes how to integrate Milesight LoRaWAN sensors with the Siemens Building X platform using a Milesight UG65 LoRaWAN gateway and a Siemens Connect Gateway. The guide uses the X500 device as an example, but the same process can be applied to X200, X300, and X700 devices.

 

The UG65 acts as both the LoRaWAN network server for the sensors and a BACnet/IP device server that exposes sensor data over the local network. The X500 gateway runs the BACnet Connector and ONEconnectivity applications, which discover and relay the BACnet data to the Building X cloud platform.

 

Data flow:

Milesight LoRaWAN sensor → Milesight UG65 (LoRaWAN Network Server + BACnet/IP Server) → Siemens X500 (BACnet Connector → ONEconnectivity → EDS Data Plane) → Siemens Building X (Data Setup → Data Visualizer).


1. Prerequisites

  • Milesight UG65 LoRaWAN gateway, connected to the same LAN as the X500.
  • One or more Milesight LoRaWAN sensors (this guide uses an AM308L and a WT304 as examples).
  • Siemens edge gateway (such as CXG3.X500) registered and online in Building X.
  • Building X subscription with Data Setup and Devices applications.
  • Milesight Development Platform account (for device management; optional but recommended).


2. Milesight UG65 Gateway Configuration

2.1 Verify Network Connectivity

Enable Wireless Network Connection on your computer and search for access point Gateway_XXXXXX(=last 6 digits of WLAN MAC address) to connect it, the default Wi-Fi

password is iotpassword.


Open a Web browser on your PC (Chrome is recommended) and type in the IP address https://192.168.1.1 to access the web GUI. Navigate to Status > Network and confirm that the WAN interface (eth 0) has received a valid DHCP address on the local network.


Go to Network > Port to review or change the WAN port settings. The default configuration uses DHCP Client, which is suitable for most installations.

Note: Make sure the UG65 and the X500 are on the same IP subnet so that BACnet/IP communication works without routing.


2.2 Configure the LoRaWAN Network Server

Navigate to Network Server > General and enable the built-in LoRaWAN Network Server. Set the appropriate channel plan for your region (EU868 in this example).



2.3 Create Application

Navigate to Network Server > Applications and create an application for device in the same collection.
