The document discusses the potential for connected home technologies to help address climate change by reducing energy consumption in homes. It notes that homes account for 30% of the UK's total energy use and that demand reduction through technologies that provide visibility and control of energy usage can help close the gap between energy supply and demand in a quick and cheap way. The document outlines challenges around connecting the many isolated devices in homes and proposes that standards and common platforms can help more applications interconnect to work together towards managing home energy use efficiently for consumer benefit.

• Demand-reduction is a quick & cheap way to reduce gap
– Approx £368k per MW saved
• Energy is the most-expensive in-home service
– Energy bill is >8% of take-home pay

• Yet we have no effective visibility or control. So we waste.
• 90% of consumers concerned, and want to save money

5. How will it all happen?

6. Car vs Home
Car: House:
• 50 microprocessors • 50 microprocessors
...working together ...all Isolated
• Doing your bidding
• Simply
• Safely
• Economically
• Visibly
...70mpg and rising

7. How will we get there from here?
• “Smart Home of the Future”
– We won’t get there in a single leap
– “Home Automation” is for geeks & millionaires
• We ARE getting there with 1:1 applications
• ...some being built on a common platform
• ...and platforms will increasingly interoperate
• Smart Metering people talk about the “HAN”
– ...but 65% of all consumers already have a HAN
• The type of PHY is increasingly irrelevant
– Online services are easiest connected... online

8. Standards
• Moving towards IP(v6) is good – but not enough
– Doesn’t deal with sleepy end-points
– Global addressing is nice, but not sufficient
– Biggest challenge to Internet of Things is Management
– Broadband routers already do an increasing amount:
• DHCP
• Firewall
• NAT
• Battle of the Gateways
– Service distributed into the gateway too
• for latency and resilience IP
