ZigBee Alliance and Device Language Message Specification (DLMS) User Association to Collaborate on Metering Data Compatibility

Work will expand ZigBee Smart Energy complex metering application support

SAN RAMON, California, November 23 - The ZigBee(R) Alliance, a global ecosystem of companies creating wireless
solutions for use in energy management, commercial and consumer applications
announced a liaison agreement with the DLMS User Association to collaborate
on metering data compatibility.

The two groups will define a method to transport IEC standard DLMS/COSEM
messages sending metering data through ZigBee Smart Energy networks. The
result will expand ZigBee Smart Energy to support complex metering
applications, and will provide utilities and energy service providers with a
standard for a variety of Smart Grid energy management and efficiency
programs and services.

"This is an opportunity to enhance the profiles of both ZigBee and DLMS
in the eyes of our potential customers," said Gyozo Kmethy, head of the DLMS
Users Association. "DLMS already has other transport options available so the
addition of ZigBee Smart Energy adds another compelling option."

The agreement with the DLMS UA adds to a growing list of strategic
relationships forged by the ZigBee Alliance with energy and international
standards groups to expand global functionality for ZigBee Smart Energy.

"Our agreement with the DLMS UA is another important move to expand
ZigBee Smart Energy's position in the global energy markets," said Bob Heile,
chairman of the ZigBee Alliance. "Utilities in Europe, North America,
Australia and other regions are looking at ZigBee Smart Energy to deliver
home area network connectivity to their Smart Grid programs."

ZigBee Smart Energy - The Standard for Energy Management and Efficiency

ZigBee Smart Energy enables wireless communication between utilities and
common household devices such as smart thermostats and appliances. It
improves energy efficiency by allowing consumers to choose interoperable
products from different manufacturers giving them the tools to manage their
energy consumption more precisely using automation and near real-time
information. It also helps utility companies implement new advanced metering
and demand response programs to drive greater energy management and
efficiency, while responding to changing government requirements. For more

ZigBee: Control your world

ZigBee is the global wireless language connecting dramatically different
devices to work together and enhance everyday life. The ZigBee Alliance is a
non-profit association of more than 300 member companies driving development
of ZigBee. The Alliance promotes world-wide adoption of ZigBee as the leading
wirelessly networked, sensing and control standard for use in energy, home,
commercial and industrial areas. For more information, visit: www.ZigBee.org.

DLMS User Association

The DLMS User Association maintains a liaison since 2002 with IEC TC 13
WG 14, the standardization body responsible for establishing standards for
electricity meter data exchange. The User Association provides registration
and maintenance services for the IEC 62056 DLMS / COSEM standards suite,
performs pre-standardization work. In addition, the DLMS UA operates the
conformance testing scheme. The DLMS/COSEM standard suite (IEC 62056 / EN
13757-1) is the most widely accepted international standard for utility meter
data exchange. This global acceptance is clearly demonstrated by the
continued fast growth of the membership, now exceeding 150, and an increase
in the number of meter types certified to be DLMS / COSEM compliant.
