There are plenty of cool thermostats available on the market. Not all of them let you control the temperature of each room. The LINQ Vent system is designed to give you room-by-room temperature control. When you replace all your vents with these smart vents, the system will be able to keep you comfortable by opening and closing vents automatically. You can also control your vents from anywhere with your phone.
Linq Smart Vents are battery powered and come in standard sizes. They are renter friendly. More importantly, the system relies on an advanced software that learns your habits and preferences and helps you save money. Each vent has temperature, motion, light, and pressure sensors. The battery should last a couple of years. Yet another interesting Kickstarter project.
