The Nexelec MASTER is a LoRaWAN–BACnet/IP gateway designed for professional building management system (BMS) deployments. MASTER connects a LoRaWAN sensor network to an existing BMS controller over BACnet/IP, converting wireless IoT data into standard BACnet points that any BMS can consume directly. An integrated 4G LTE modem with SIM card provides secure remote access and NAVIXIS cloud supervision alongside the local BACnet/IP connection. MASTER ships pre-configured and ready to use: plug in the power cable, scan the QR code, and the LoRaWAN network is live within minutes. The IP67 enclosure supports indoor and outdoor wall mounting without additional protection. Surge protection and internal or remote antenna options are built in. Key Features LoRaWAN to BACnet/IP conversion: LoRaWAN sensor data is automatically decoded and converted into standard BACnet points, interoperable with all BMS controllers and PLCs. No custom integration work required. BACnet/IP connectivity: Connects to the building controller over Ethernet on the same IP network as the BMS — direct, standards-based integration with existing infrastructure. 4G LTE connectivity: Integrated multi-operator SIM card provides secure remote access for monitoring, diagnostics, and firmware updates over 3G/4G without a local network connection. NAVIXIS supervision platform: Cloud-based IoT management included. Monitor LoRaWAN network performance (signal strength, transmission quality, equipment status), visualize sensor data, set threshold alerts, and access data via API or webhook. Data stored on secure servers for up to 3 years. Compatible with a wide range of LoRaWAN equipment: Connects air quality, energy, security, and other LoRaWAN sensors and devices. Automatically distributes connected devices across the most suitable gateway when multiple gateways (MASTER or LINK) are deployed. Ready to use out of the box: Main settings pre-configured at the factory. Plug in the supplied power cable and scan the QR code — LoRaWAN network active within minutes. Modular installation: Can be installed indoors or outdoors. Internal or remote radio antennas available to optimize coverage. On-site configuration takes minutes via the Nexelec mobile app. IP67 waterproof enclosure: Robust protection against dust and water ingress. Compact, sleek design blends into professional environments — suitable for machine rooms or publicly accessible areas. Built-in surge protection: Protects the gateway against electrical voltage fluctuations that could damage internal components. Simplified power supply: Supplied with a 3 m power cable and standard plug — connects directly to a standard electrical outlet. No special wiring required. Dedicated technical support: Nexelec support team assists professionals at every stage of the commissioning process. Certifications: CE, UKCA, FCC Applications Connecting LoRaWAN sensor networks to building management systems via BACnet/IP Indoor air quality, energy, and security monitoring in commercial and institutional buildings Multi-site LoRaWAN deployments with centralized NAVIXIS supervision Retrofitting existing BMS installations with wireless IoT sensor coverage Professional IoT projects requiring standards-based BMS integration and remote management Important Notes MASTER requires mains power (supplied cable). No battery backup is included. BACnet/IP integration requires an Ethernet connection on the same network as the BMS controller. NAVIXIS platform access is included with MASTER. Additional optional software modules (air quality, energy, fire safety) are available — contact us for details. Other LoRaWAN frequency bands and communication protocols are available. Contact us to discuss the configuration for your project. LoRaWAN sensors and devices are not included and are ordered separately.
