Keen has what looks to be a pretty smart product the company is calling Smart Vent. It's an Internet-connected vent that helps control the temperature in your home room-by-room. The devices are controllable through an iOS or Android app when connected through a Keen Smart Bridge (a $39 hub for the company's Internet-connected devices). It also works with Google's Nest thermostat. We haven't tested the Smart Vent yet, but when I saw it over the weekend, it screamed "cool" at me. $79 gets you a Smart Vent with a herringbone design on the vents. $129 gets a brown vent called "Arbor" that looks like a microscopic closeup of a leaf. There are also optional Smart Filters made by 3M that will be available in February.
