The Number of Certified Devices in the OMS Product Listing Reaches 80

Since June 2023 there is an increase of five new OMS-certified devices supporting OMS Generation 4.


Itron/Allmess contributes three new devices: The "EquaScan eHCA RF V2", an electronic heat cost allocator with radio communication, the "EquaScan hMIU RF", a heat meter module and the "EquaScan wMIU RF", a water meter module. This was followed by two devices from Maddalena, the "ElecTo Sonic", an electronic ultrasonic meter, and the "ElecTo MVM Multiprotocol", an electronic volumetric meter. Furthermore, numerous certificates and datasheets for existing devices were extended or renewed, which clearly shows that the interoperable OMS devices are experiencing high and steady demand.

OMS certification ensures compatibility with the OMS Specification and opens a broad market for manufacturers of interoperable smart meters. Currently, 80 devices are listed on the OMS website.
Relevance of OMS for Smart Metering/Submetering Using the Smart Meter Gateway-Infrastructure with OMS

With the initiation of the German legislation called GNDEW (Gesetz zum Neustart der Digitalisierung der Energiewende) in May 2023, the rollout of the Smart Meter Gateway (SMGW) in Germany is now accurately defined. As reported in the latest OMS Newsletter news4all in May 2023, the SMGW will serve as a centralised communication platform for future buildings, ensuring maximum data protection and security. As such a secure communication-unit, the SMGW becomes the functional core of smart metering systems to enable a „sector coupling “. Which means the main measurement of electricity can be bundled with measuring of gas, water or heating energy and submetering.

Besides the requirements to functionality and security, components in the smart meter system environment have to fulfil demands regarding the interoperability. In Germany these requirements are defined in technical directives (Technische Richtlinien, TR), generated by the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, BSI). The TR-03109-1 defines the above-named requirements for the following relevant interfaces: the Local Metrological Network (LMN), which connects meters for electricity, gas, thermal energy and water and the Home Area Network (HAN); the interface for Controllable Local Systems (CLS) is categorised to the HAN. Details of the optional connections to the CLS are specified in the expected TR-03109-5.

image The Open Metering System (OMS) enables interoperability between metering devices and integrates the media electricity, gas, heat, and water incl. submetering in one system. By supporting the development and evolution of a future-proofed communication standard, the OMS Specification’s „Volume 2 – Primary Communication“ in context to the EN-13757 are also relevant and mandatory for wireless connections at the LMN interface of the SMGW referring to the TR-03109-1.

Regarding the Heating Costs Ordinance (Heizkostenverordnung, HKVO) in Germany, interoperability becomes more relevant for submetering-devices, as well. Furthermore, the HKVO refers to the State-of-the-Art compliance, which prospectively could require the connection to the SMGW for submetering. Following the released BSI papers in 2021, especially the „Step Model for the further Development of Standards for the Digitalisation of the Energy Transition“ and as well due to the State of the Art, it is recommendable to observe the expected TR-03109-5.

The TR-5 will prospectively describe the State of the Art for communication units connected to the HAN, respectively, the CLS interface – and also submetering-units are "technical equipment" for the purposes of the TR. Connecting the submetering-devices to the CLS imageinterface and transmitting metering data over the SMGW is an available solution provided by QUNDIS called „BSI-conformed Submetering “.

Conclusion: OMS is a future-proofed standard, implemented in the specification of the TR-03109-1, which supports the evolution of interoperable metering devices as a key target. Furthermore BSI-conformed submetering over the smart meter gateway-infrastructure is available for OMS devices.

News from the OMS-Group’s Executive Board

It has been eight months since the last news from the OMS EB. In that issue, I spoke about the necessity of having a statutory basis in Europe regarding remotely readable cold-water meters.

With the announcement of the “Declaration for an EU Blue Deal” in October 2023 of the European Economic and Social Committee (EESC) we are happy to see that the EESC is leading the way as the first European institution to take concrete steps to address the water crisis. Furthermore, they call on the European Commission to start making water a primary issue and to propose an EU Blue Deal as a standalone strategic priority, on a par with the EU Green Deal.
Among the challenges the EESC addresses are a “sustainable and resilient water infrastructure” and a “sustainable use and consumption of water and fostering new opportunities”. Water meters are a small but integral element to the realisation of a possible EU Blue Deal, however, as often is the case, they are not specifically mentioned. It is important to note, you do not have to be an engineer to know, you cannot monitor and improve, what you do not first measure.

Therefore, we intend to team up with associations active in the water sector to offer the OMS communication as the solution to make data from water meters available as a basis for one of the already identified opinions on the topic of “Water efficient consumption and consumer awareness about their water footprint”.

The OMS EB has already held its final meeting for 2023 in the beginning of November. A highlight of the year will be the General Meeting of the OMS-Group, to be held on December 7 at DIN in Berlin after three years of virtual meetings. The OMS GM will decide about further changes in the OMS-Group’s Articles of Association, thus securing the OMS-Group’s assets regarding certification and licencing.

So, stay tuned for more information after the General Meeting 2023 of the OMS-Group.
