Keen Home - Smart Vent Starter Kit 4" x 10" - White

Adding these vents to an Ecobee thermostat and room sensors basically made every room able to control it's own temperature. It fixed the cold room over the garage by automatically closing other vents in the house to force air where it needs to go. I love it. I do have these on every vent controlled by the thermostat and room sensors.

this works so well, these guys really have solved the issues in my 3,200 square foot home. I can control each room perfectly. I recommend this paired with the ecobee 3 and remote sensors. Soon the team said they will have their own sensors. This is a great product if you have multiple floors. i have complete control of the temp. Thanks guys

I have them installed on all my main floor vents to push air to 2nd level to balance temps. Still waiting on ways to measure this with reports from Keen. Recent Ecobee support is a plus.
