Homes are Not a Power Panacea 30-40 outlets per house Long wires 2.3x more down time than
batteries More maintenance calls

Homes Have Poor Connectivity Wireless connectivity
Power line communications Wires 180bit/s 5 min polling rate Exploiting Home Automation Protocols
for Load Monitoring in Smart Buildings
