Live more comfortably and efficiently by controlling the temperature of your home room-by-room with Keen Home Zoning using Smart Vents and Temp Sensors.

The Keen Home Zoning System gives you full control of your home’s heating and cooling at the individual room level. Smart Vents are completely safe to use with any central HVAC system.

Easily connect your Smart Vents, Smart Bridge, and Temp Sensors in the app with quick access to tutorial videos and troubleshooting help.

Automatically control temperature and airflow with Smart Vents and Temp Sensors in rooms that are too hot, too cold, or not in use. Set schedules, set room temperatures, and control compatible thermostats.

Keen Home Smart Vents integrate with the Nest Learning Thermostats, ecobee3 and ecobee4 thermostats, and new integrations are added regularly. Use the Keen Home app to connect to a Nest or ecobee thermostat, and to any number of future integrations. With the Nest and ecobee integration, you can control your smart thermostat right from the Keen Home app. Expect updates and new features over time.

Love this system

I bought the system more for aesthetics because of the vents. Paired it with the Ecobee thermostats and Ecobee room sensors. Set up two zones with a total of 12 vents, a bridge and repeater. I can either use the Keen app or Ecobee app to make changes. The two systems communicate with each other every 3 to 5 minutes and every room has been accurate to the temperature set.
The only wish I have is redesigning the Keen app. It’s a pain to change the individual temperatures using the sliders on the app. It would be much easier and accurate to use a drop down menu to choose the desired number. Change that and you get 5 stars.
Most important, the first month of use lowered energy cost approximately 29% compared to last year with the same average temp. If that remains consistent, the Keen purchase plus the cost of the Ecobee will be paid for in 12 months. I think that’s a worthwhile return the investment.......


Great hardware

I am really impressed by the quality of the hardware of these vents. The software has been a bit of a let down. Originally they tried to use an internal temperature sensor to help automatically adjust the vent. This never worked very well and I always wondered how the vent would measure accurate ambient temperature in the room. The sensor placement would be better if it was where the people live. Now the app no longer has this feature. It has a simple schedule for occupancy of the room. I really like how easy this is and wish it was like this from the beginning. If I want automatic adjustments, I’ll buy some of the temperature sensors.


Does not work as advertised - Poor support

I bought this vent system 2 years ago. It was supposed to use temperature sensors in the vents to open and close them to balance the temperature across rooms and make heating and air conditioning more efficient. It has never done this. The automatic system has been ‘beta’ the entire time and does not work. The vents often go offline, requiring the batteries to be removed and reinserted. They sent out new battery packs with padding around the batteries, which hasn’t helped. Now they are plugging external temperature sensors you need to buy. They are supposed to be using the ones built into the vents, but those apparently don’t work either. I would avoid this system until the software is out of beta and working as promised.
