The smart home race is getting into high gear and no single leader has yet emerged.

At the moment, it looks like there are four major leaders in the smart home space, all household tech names.

When asked in a recent study which brands are the leaders in the smart home technology race, Google, Amazon, Samsung and Apple all received equal rankings by consumers.

The study to measure smart home device adoption comprised an online survey of 700 U.S. adults conducted by the research firm Gut Check.

Following those four were, in order, LG, iRobot, Nest, Bose, Philips, Ring, Kohler, Belkin, Sonos, Wink, Ecobee, Lutron and August.

Smart home hubs likely have the most opportunity for adoption, since the spread between awareness and ownership is high, with 67% being aware of devices such as Google Home and Amazon Echo, but usage is at 46%, according to Gut Check.

More than half of consumers say they are likely to buy a smart home device in the next year, either as a first purchase or an addition to smart home devices already owned.

The leading categories relate to safety and security, entertainment, home management and appliances. More homes will be getting smart.
