The evolution of Meters and More


Meters and More, a global non-profit industry organisation, maintains and promotes the Meters and More protocol for bi-directional data transfer in advanced metering infrastructure (AMI) systems. This new generation powerline, also known as SMITP (smart metering information and telecommunication protocol), communications protocol, is internationally recognised as a technical specification for smart grid communications at CENELEC (CLC/TS 50568) and is the most widely deployed communication protocol for remote meter management.

Meters and More was created in 2010 from the coordinated work between Enel and Endesa to adopt, maintain and evolve the field-proven Meters and More open communication protocol for smart grid solutions. Since its foundation, many of the world-leading companies and institutions from different business sectors have joined the Association, making Meters and More the most field-proven solution for smart metering with nowadays more than 45 million devices on field, with a special focus in Europe and Latin America. The Association goal is to enable interoperability between devices, applications and services by open industry specifications without IPR limitation, ratified by a certification process to assure product compliance with Meters and More specifications and drive protocol evolutions. In order to reach these targets, the Association has been organised into three committees: the Committee for Product Certification and Committee for Protocol Specifications; and a promotional committee, Committee for Communication Activities. All are driven by strategic guidelines from the Meters and More Board of Directors.

A decade of noteworthy achievements:

SMITP is one of the technologies recommended by the European Open Meter Project and has been awarded technical specification status (CLC/ TS 50568) from the European Standardization organization CENELEC, in compliance with mandate M/441 of the European Commission;

The definition and set-up of a neutral certification process developed and monitored by the association’s Committee for Product Certification with the appointment in 2015 of CESI S.p.A as the first laboratory accredited as a Meters and More Test Provider.

The smart energy gateway protocol specifications and demo as part of the ‘beyond the meter programme’ of the association. Making consumption data available in ‘near real-time’ to the end customer has proven a fundamental step to obtaining reductions in energy consumption and demand. In this context, Meters and More has extended the protocol for communication between the smart meter and in-home devices, enabling the interchange of energy consumption information as well as the inclusion of new services. The first prototype of the Meters and More smart energy gateway, implementing the new protocol extension, aimed at accelerating smart energy and IoT benefits for consumers in accordance with European Commission recommendations on the provision of energy consumption information.
