The adoption of OMS over LoRaWAN is entering into commercial availability.
Several smart metering solutions are being now commercially available with BIRDZ, ELVACO, KAMSTRUP, ZENNER and others that are the first paving the way for utilities to rely on M-Bus standard in OMS-based applications and end-devices featuring the LoRaWAN connectivity.
Here below are statements from Semtech customers and partners and information on available or new solutions for OMS over LoRaWAN:
“Birdz is proud to have been able to actively participate in and lead the "TF OMS over LoRaWAN" task force, giving birth to the OMS over LoRaWAN mode. After a demonstration with its partner Diehl Metering at ENLIT 2023, this new communication mode is now embedded in the new range of water meter products featuring Birdz's "B-Inside SM4" technology.
This new-generation water meter solution enables communication using Birdz's proprietary protocol, LoRaWAN, Wireless M-Bus and, of course, OMS over LoRaWAN. It will be available from summer 2024 from our partners Diehl and Itron. The same solution will be duplicated on Birdz's remote range from Q2 2025.”
“Elvaco has been part of the joint task force between LoRa Alliance and OMS group which has resulted in a M-Bus Adaptation Layer. We are proud of enabling OMS support with our LoRaWAN end devices for heat metering. Thanks to the M-Bus Adaption Layer specified by the joint taskforce, we will be able to support customers demanding for interoperability and reliability of the OMS standard.”
List of devices from ELVACO that would be ready for OMS over LoRaWAN:
CMi4110 - Integrerad MCM för Landis + Gyr UH50/UC50, LoRaWAN | Elvaco
CMi4111 - Integrated MCM for Landis+Gyr T230/T330, LoRaWAN | Elvaco
CMi4130 - Integrated MCM for Itron CF ECHO II/51/55, LoRaWAN | Elvaco
CMi4140 - Integrerad MCM för Kamstrup Multical 403/603/803, LoRaWAN | Elvaco
CMi4160 | Elvaco
CMi4170 LoRaWAN Modul Int Ant | Elvaco
''KAMSTRUP is excited to announce the residential water meter KWM2231 series has been LoRaWAN and OMS certified, enabling seamless integration with third-party systems according to OMS and allowing efficient fallback with Wireless M-Bus.''

“STACKFORCE is very proud to have launched another powerful software product in early 2024 with the Dual Stack OMS® v4.5.1 + OMS® over LoRaWAN (TR06)®. This addition to our portfolio significantly contributes to the ongoing standardization in the metering sector. Thanks to the M-Bus adaptation layer specified by the joint working group of the OMS® Group and the LoRa Alliance our product can support customers who are looking for the interoperability and reliability of the OMS® standard while benefiting from LoRaWAN® technology.”
Software stack can be fully available by STACKFORCE:
LoRaWAN product, the “Dual Stack OMS v4.5.1 + OMS over LoRaWAN (TR06)”

“ZENNER is really proud to be one of the first mover of enabling OMS support with our LoRaWAN end devices. Moreover ZENNER provided its Element platform as development and testing platform for several stakeholders.
Thanks to the M-Bus adaption layer specified by the joint taskforce of OMS group and LoRa Alliance, our company will be able to support customers demanding for interoperability and reliability of OMS standard.”

To understand the real advantages of having new solution using OMS over LoRaWAN, it is key to acknowledge how the OMS using M-Bus and LoRaWAN complements well each other:
M-Bus applications are suitable and well established in smart metering but the radio used in Wireless M-Bus does not have long range radio.
The LoRa modulation used in LoRaWAN provides long range communication but is “Application Agnostic”.

OMS and LoRaWAN complement each other because:
モノの LoRa Alliance Live Event conference in Munich, of 2024 June 20th, the OMS-Group e.V gave an important session to highlight the achievements of the liaison, that began in 2019 between the LoRa Alliance and OMS, and explain the stack architecture of OMS over LoRaWAN using the M-bus Adaptation Layer (MBAL) for LoRaWAN that was published in technical report TR06 on OMS Group website. Following a comprehensive review and voting process in 2023, the European Normalization Committee (CEN) has officially standardized and extended the M-bus Adaptation Layer (MBAL) for third-party networks, referencing it as EN 13757-8:2023. Among all LPWAN technologies, LoRaWAN stands as the pioneering connectivity use case.
The LoRa Alliance represented how the OMS Application layer fits within the LoRaWAN architecture using the MBAL link layer:
For more context and details on the importance of standardization for smart metering, please consider our previous blogs:
Now, OMS and LoRa Alliance are continuing their joint efforts to create the certification of smart meters and utilities end devices that will allow utilities enable OMS over LoRaWAN using this M-bus Adaptation layer. It’s important to remember the CEN makes only standard but not certification.
Therefore, the utilities requiring certification of smart meters and other end devices for best reliability and interoperability will rely on the two certification together:
the OMS certification for the application including the M-Bus Adaptation Layer (MBAL), and
the LoRaWAN end device certification by the LoRa Alliance.
By incorporating OMS over LoRaWAN properly, the smart meter and end device manufacturers can ensure compliance with OMS and with CEN standard to ensure reliable interoperability, easier and seamless integration, and future-proof solutions.
Customers can use all Semtech LoRa products and rely on our software partners to get the adaptation layer software MBAL (EN 13757-8:2023) :
ELVACO : solution built for LoRa Basic Modem compliant with OMS over LoRaWAN (TR06)
Stackforce : solution built on top of LoRaMAC node. Stackforce provides a Dual stack, that supports seamless switching between legacy Wireless M-Bus (OMS v4.5.1, modes S/T/C) and OMS-over-LoRaWAN (TR06) at runtime.)
