MQTT to LoRaWAN Converters – industrial IoT gateways with support up to 32 devices

MQTT to LoRaWAN Converters – reliable gateways for IoT and Smart Metering

MQTT to LoRaWAN converters are advanced communication devices designed for seamless integration between LoRaWAN-based sensors and meters and MQTT servers. They enable the secure publishing of data collected from distributed devices directly into IoT platforms, ensuring full interoperability with supervisory systems. Supporting up to 32 LoRaWAN devices, these gateways are ideally suited for smart metering, smart city projects, and a wide range of industrial automation applications.

Frequency ranges and device compatibility

Converters available in this category support multiple frequency ranges, including 169 MHz and 868 MHz, making them compatible with European and global LoRaWAN deployments. This flexibility ensures that the devices can be adapted to various industrial and municipal projects. They can monitor and integrate with meters from manufacturers such as SIEMENS, Kamstrup, Maddalena, Sontex, and other LoRaWAN-compliant devices.

• Up to 32 LoRaWAN slave devices supported per converter.
• Frequency options: 169 MHz or 868 MHz depending on the model.
• Protocols: LoRaWAN (wireless) and MQTT (Ethernet).
• Interfaces: Ethernet RJ45, SMA Female antenna connector.
• Electrical isolation between Ethernet and LoRaWAN interface.

Industrial performance and robust design

Each MQTT to LoRaWAN converter is built to withstand demanding industrial environments. Operating temperatures range from -40°C to +85°C, ensuring reliable performance in outdoor cabinets, substations, and non-climate-controlled facilities. The devices feature a wide power supply range of 18…35 VDC (or 15…21 VAC), allowing them to be integrated into various energy infrastructures.

• Power supply: 18…35 VDC or 15…21 VAC
• Maximum power consumption at start-up: 30 W
• Housing dimensions: 71 × 60 × 95 mm
• Weight: approx. 200 g
• DIN rail mount (35 mm) for easy integration into control panels
• Free configuration software: SW67931

Secure communication and configuration features

All converters support TLS/SSL encryption, ensuring data security during communication with MQTT servers. This is essential for critical infrastructure applications such as water distribution, district heating, or energy monitoring. Configuration is straightforward thanks to the dedicated SW67931 software, which allows users to:

• Define MQTT line parameters
• Configure LoRaWAN line settings
• Select variables to be published to the MQTT server
• Update device firmware

Why choose MQTT to LoRaWAN converters?

MQTT to LoRaWAN gateways are chosen by system integrators and IoT operators for their scalability, secure communication, and broad compatibility. The ability to manage up to 32 devices, support for both 169 MHz and 868 MHz frequency ranges, robust encryption, and industrial-grade design make them a reliable backbone for smart metering, industrial IoT, and smart city infrastructure. With these converters, data from distributed field devices can be efficiently transmitted to centralized platforms, enabling optimized operations, reduced maintenance costs, and enhanced system visibility.
