Wow, I tried really hard to make that headline exciting, but it just didn’t work. That’s okay, because I think this little device is a good idea, even if it’s not particularly flashy. These automated vent covers let you control airflow to individual rooms on whatever schedule you choose. No, it’s not cool, but if you own a house it sure is practical.
The vent will open and close according to whatever schedule you choose, which, depending on how your home is heated and insulated, could save you a fair bit of cash over a year. The vents cost less $30 each so it’s not much of an investment, and will probably pay for itself pretty easily.
