The IDIS Association and DLMS User Association announced a merger agreement in November 2021. The current activities of IDIS will be integrated into the DLMS UA and the combined association will drive innovation through interoperability and standardization supporting forward-looking multi-utility and energy-as-a-service trends. The DLMS UA will continue to deliver world-leading specifications and certification programs guaranteeing the highest level of compatibility and serve as the Go-To standard and certification platform for data exchange in IoT and strategic energy and water management.

Already today the DLMS/COSEM standards cover some smart grid features (e.g. load management) the functionality is extended following the market needs. Load management functions are already covered in the interoperability Package 1.

As three innovative smart metering solution providers, we feel responsible to convert the existing standardization framework into real interoperable products. We are encouraged to undertake this investment by the EU directive and by the mandate M/441. The EU directive confirms our strategy to support energy conservation by providing efficient smart metering solutions based on open standards. We are very glad that the EU commission supports our view by mandating smart metering standards to the European standardization organizations. Supported by theses two EU initiatives, we will contribute to the strengthened presence of the European industry to establish the worldwide lead in open standardized metering solutions. We will actively participate in the activities launched with the M/441 mandate by maintaining and extending the existing standards in order to ensure future developments in technology can be considered within the existing standardization framework.

IDIS is based on existing open standards, what is new is the implementation of these standards. The three companies fully support activities of ESMIG and of the standardization organizations. Naturally the three companies will feed all experiences gained by implementing the existing standards to the standardization organizations and to ESMIG. We hope that idis will also encourage other manufacturers to follow our approach.

IDIS is completely based on open, official standards (as declared in the IDIS openness declaration) which are published by standardization committees fulfilling the openness requirements of the EU commission*). Today, there does NOT exist any standard for the DC-HES interface. Therefore, members of the IDIS association initiated a standardization project in IEC TC13 WG14 (project 62056-9-1) to define a web service based protocol which is suitable for the interface between DC and HES. The first proposal is expected to circulate via the IEC national committees in April 2014. Once the standard is established IDIS will consider it in its specifications. Following this procedure IDIS demonstrates its commitment to openness according to the requirements of the European authorities. *) The European Union uses the following definition of OPENNESS in its European Interoperability Framework: The standard is adopted and will be maintained by a not-for-profit organization, and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties (consensus or majority decision etc.) The standard has been published and the standard specification document is available either freely or at a nominal charge. It must be permissible to all to copy, distribute and use it for no fee or at a nominal fee. The intellectual property - i.e. patents possibly present - of (parts of) the standard is made irrevocably available on a royalty-free basis. There are no constraints on the re-use of the standard

Yes. IDIS Package 2 certification will remain available for new certifications until the end of 2023. After that period, it will only be available for re-certifications of existing products that hold an IDIS Package 2 certificate in the case of firmware changes.

Yes. Now that IDIS Package 3 certification is available, it will only be possible to certify new devices against IDIS Package 2 until the end of 2023. After that period, IDIS Package will only be available for re-certifications of existing products that hold an IDIS Package 2 certificate in the case of firmware changes.

In the interest of full transparency for our members, the DLMS UA aims to publish the first DLMS UA Generic Companion Profile for AC smart meters in Q1 2023. Qualification for certification for this first Generic Companion Profile, the ACESM GCP (AC Electricity Smart Meter Generic Companion Profile) will be available in Q3 2023. Once the qualification process for the new DLMS Generic Companion Profile is launched, the certification process for IDIS P3 will end within three to six months. After that time, only recertification of existing products that hold an IDIS Package 1,2 or 3 certificate will be possible. We expect IDIS P3 certification for new devices to cease sometime between Q4 2023 and Q1 2024. We will communicate the exact dates at a later date.
