New Parks Associates research shows that 23% of U.S. smartphone owners also own a smart home device and over three-fourths of those consumers use their smartphone, tablet, or PC to control their smart home devices at least once per month.

Purchase intentions for smart home devices among U.S. broadband households more than doubled in less than two years, going from 21% in early 2014 to nearly 50% at the end of 2015," said Stuart Sikes, President, Parks Associates. "Safety and security are the main drivers for consumer interest, and we see, once smart home products are in the home, consumers quickly develop habits with these devices. Usage varies based on device, but among owners of most safety and security devices, 40-50% control or monitor these products on a daily basis."
