This smart front door can go from clear to opaque with a voice command

Glass front doors are great for letting light in during the day but not so great when you want privacy at night. The Home Depot has a smart solution for this problem - a glass front door that can switch from clear to opaque on a schedule, with a voice command, or by pressing a button.

The smart glass Feather River door is a prehung fiberglass front door with built-in smart glass. A button on the door lets you change the glass from clear to opaque, and it works with The Home Depot's Hubspace smart home app to control it from your phone. You can also set the glass on a schedule and have it be clear during the day and opaque at night. The door costs $798 for a three-quarters lite, $899 for a half lite, and $998 for a full lite, similar to a non-smart front door.

Hubspace is The Home Depot's attempt at demystifying the smart home for its customers. Despite the name, the smart home platform doesn't require a hub, just the Hubspace app. With it, you can connect and control a wide range of The Home Depot's store brands, from smart lights and shades to bathroom fans and thermostats.

The smart glass door is the retail giant's first Hubspace collaboration with a third party. It works with the Hubspace app and can connect to smart home systems like Amazon Alexa or Google Home to use a voice command to make your door clear or opaque.

The smart glass works over Bluetooth and Wi-Fi and requires power. The door has a battery built into the frame, which a USB cable can power if you have an outlet nearby. The battery is removable, and the door comes with a second battery and a charger.

The battery only powers the glass and the connectivity. Unlike The Home Depot's first attempt at selling a smart door - the $4,000 M-PWR smart door from Masonite - the Feather River door doesn't feature built-in power for a smart doorbell or door lock. It's a standard door outside of the glass. You can add a battery-powered smart lock, and the door acts as a Bluetooth-to-Wi-Fi bridge for Hubspace-compatible Bluetooth locks.
