In terms of homes that have a broadband connection as a market for home automation, the market size turns out to be around $8.8 billion at $100 spent per home or $880 billion at $10,000 for the U.S. If we are a little more conservative and say that only those broadband subscribers who use smartphones are targets, the range turns out to be about $5.63 – $563 billion. In order to capture this opportunity a number of business models have come into play. While these are not new business models, it is interesting to see how this opportunity is being captured.
