Have a pet who wants to go in and out of the back door all day long? Don't want or can't install a dog door? There's some simple tech that can help!

The Wayzn is an automatic sliding glass door opener for your pet.

Much more elegant than a traditional dog door, the Wayzn fits in just about any size sliding glass door and can be activated by its app. But it also can be triggered by a sensor on the unit when your dog approaches. There's even a way for you to have your smart speaker activate it.

The Wayzn is $500.
