August was one of the first companies to offer a smart lock. With the Wi-Fi Smart Lock, they've finally perfected the formula. Once again, it has a Yves Behar design, yet it is 45% smaller and 20% slimmer than the prior Smart Lock Pro. Built-in Wifi lets it interface with Google Assistant, Alexa, and Siri without the need for the Connect bridge, while also letting you manage access from anywhere with Internet. DoorSense technology makes sure that the door is securely closed and locked, and it installs over most single-cylinder deadbolts in less than 10 minutes.
