Keeping your home even temprature throughout can be a challenge, especially with some forced air systems. Rooms are like the beds that the three bears kept: to cold, to hot or just right. I am always staying on top of he latest technology and Keen has a great solution. They were profiled on SharkTank a few years back.
The Keen Zoning System
Smart Vents™ adjust airflow to over-conditioned rooms and redirect this airflow to rooms that need it most. Temp Sensors and the Smart Bridge allow the Keen Home smartphone app to set schedules, set specific room temperatures, and control compatible thermostats.
