Craftsman's AssureLink now allows you to control your garage door from a smartphone. And you don't have to buy a new garage door opener -- this kit serves as an upgrade for existing Craftsman garage door openers. It comes with an AssureLink motion-detecting wall control that has a built-in transceiver radio, an AssureLink Internet Gateway Module with a power cord, and an Ethernet cable. Not only does it let you operate the door, but it also allows you to monitor it from anywhere you have an Internet connection.

Price: $130.
