HC-003-55 LoRaWAN

The LoRaWAN® module enables secure and energy-efficient long-range communication for Kamstrup’s MULTICAL® 403 series of heat and cooling meters at 868 MHz.

It is designed to meet modern requirements for remote meter reading, data integrity, and cybersecurity, while maintaining full backward compatibility with existing installations.

The module supports unidirectional LoRaWAN communication, allowing meter data to be transmitted reliably to the head-end system (HES) without the need for bidirectional control. In addition, the module includes wireless M-Bus OMS C1 interfaces, providing local readout, on site configuration, and a robust fallback solution if LoRaWAN connectivity is temporarily unavailable. 

Security is an integral part of the design. All LoRaWAN and OMS encryption keys are generated directly from the meter’s internal Data Encryption Key (DEK) or derived through the Kamstrup Security Concept, ensuring complete traceability,  authentication, and protection of sensitive data throughout the device’s lifecycle.

The flexible configuration concept allows utilities to tailor transmission intervals, data content, and adaptive data rate (ADR) settings to match network conditions and energy requirements. With a highly optimised power profile, the LoRaWAN module ensures long battery life and stable performance even in challenging RF environments.
