According to Parks Associates, 60% of U.S. broadband households planning to buy a smart home product heavily favor solutions that work with the devices they already own. Among smart speaker owners planning to buy a smart home product, 64% want a device that works with their smart speaker. The research house also says purchase intentions for smart home products overall have increased from 35% in 2016 to 43% at the end of 2018, a 23% increase in two years.

Parks says smart speakers continue to shape the smart home experience for users by providing a simple and intuitive way for them to control and interact with other devices in the home.

"The smart home ecosystem is crowded with many leading devices, including smart thermostats, networked cameras, smart video doorbells, smart door locks, and smart light bulbs," said Chris O'Dell, research associate, Parks Associates. "As interoperability continues to increase in importance, companies that are vertically aligned or have the right 'works with' partnerships will have an advantage among likely buyers."
