What will convince consumers that a connected home is worth the cost and effort? Device makers hope to sell the idea that a connected home is not just safer, but also saves money and is ultra-convenient.

Smart home devices must automate daily mundane tasks so the homeowner doesn't have to worry about them, said Stuart Sikes, president of the research firm Parks Associates.

"We're moving to a place where we have proactive home managers, devices that turn off the water and notify you after the fact that you've had a leak, the water's been shut off, can I do anything else for you?" said Stuart Sikes, president of the research firm Parks Associates. "That is a true smart home."

Take Google's Nest Learning Thermostat, for example, which costs $249. Manufacturers claim the gadget saves an average of $131 to $145 a year in heating and cooling bills. But a smart system could add to those savings by telling the blinds on the home's western windows to automatically close at 5 p.m. to block the sun.
