Shops don’t take your money without asking, so why should
your home appliances use scarce electricity resources without
consulting you? Current “smart meters” are pretty useless,
because house occupants have to guess where the power is
going. Local company Informetis has an Internet of Things
device that sends a WiFi stream of power consumption from any
appliance. Your task is to make an app that will aggregate and
visualise this data to help households budget for a future where
energy costs 10 times what it does today. When energy is
rationed, what will work best? Neighbourhood contests,
household policies, online games or financial incentives? Your
system design needs to address motivation, not just monitoring.
