Products that speak Z-Wave work together better.

IntroductionZ-Wave = ONLY interoperable market success for wireless HAN Established in the market, 300 products, 200 companies, various channels, many application all INTEROPERABLE

Z-Wave for smart metering HAN can be tied well to other last mile ZW f t t i b ti d ll t th l t il solutions via bridge architecture as well as integrated to IP via Z/IP Horstmann and Trilliant products / examples / demos

Z-Waves ecosystem in the UK (HVAC & lighting) can be greatly leveraged for energy display A Horstmann or Danfoss thermostat can double duty as an energy display and reduce utilities investments on the display roll-out

Z-Wave is being opened up through collaboration with Cisco in the Z-Wave alliance and the convergence with IP in Z/IP Z-Wave will have 2nd source silicon through the investment of Panasonic in Zensys Z-Wave has a new full device class for smart metering Zensys Inc., 2008 Confidential

Products that speak Z-Wave work together better.

What you need to knowZensys has always focused on the network / ecosystem first before driving the gateways (smart meters) In the UK the key light control companies and HVAC companies have Z-Wave products or will have them soon It does not make any sense to be the only fax machine in a network Would love to introduce these UK companies to let them tell why they chose Z-Wave and what they can do for you

Z-Wave has roll-out and trials in smart metering (Horstmann, Modstroem, DEST) but have not yet been beating the PR drum. Z-Wave contains all IP needed for HAN Z Wave Avoid IP infringement lawsuits during trails and roll out as seen recently in rollout in Southern California.

Z-Wave operates on the well regulated 868MHz band No interference from WiFi!Products that speak Z-Wave work together better.

The Z-Wave AEC VisionWhy create a new Monster? Leverage on the existing flexible Z-Wave technology!Why create new classes of Smart appliances? L t leverage on th many existing d i Lets l the i ti devices supporting l d shedding and temperature setting etc. ti load h ddi dt t tti t Lets leverage on the many existing devices supporting sub-metering The intuitive way for Consumption analysis Then - Allow manufactures to enrich their products No new SKUs which cannot be used with other initiatives to implement even better energy conservation mechanisms going forward.

Why create new classes of information displays? Lets use the displays already in Z-wave products such as remote controllers and thermostats Then - Allow manufactures to add the strong Z-Wave security options to protect sensitive data

Why re-invent Security and Remote Home Access strategies? Lets use IP or other WAN technologies providing the last mile communication, an excellent and proven quality of Service and mature Security (like SSL or TLS) Then - Allow manufactures and Utility Suppliers to leverage on their IP knowledge and enrich existing backend application and IP Gateways

Instead, lets focus on the important NEW problem to solve ! Create a scalable data distribution architecture for ALL devices. Whether low-cost or High-end.

Danish Electricity Savings Trust recommends Z-WaveThe Danish Electricity Saving Trust is a governmental, non-profit organization whose mandate is to help consumers and public sector institutions save electricity. Main reasons for recommending Z-Wave: Z-Wave Alliance and communication protocol are open to everyone at low cost The hardware comprises an inexpensive chip for integration into devices Z-Wave Alliance ensures interoperability between Z-Wave-equipped devices A rapidly growing market share Low power consumption makes battery-powered sensors and switches a reality battery powered 30-metre operating distance can be considerably extended thanks to rerouting/meshing

SMIQ,MUC and Open MeteringGerman utility companies and energy suppliers came together to have a unique standardised solution for smart metering (SMIQ/MUC) The involved manufacturers are in discussion Open Metering was founded as Working Group to investigate a standardised solution which will be accepted by all parties Based on the requirements of SMIC and MUC, existing standards were evaluated evaluated. Based on EN13757, the Open Metering System specification was created.
