Flair will work with all thermostats!
Regardless of what thermostat you have, Flair Smart Vents will open and close automatically to balance airflow across your home.
If you're looking to buy a smart thermostat, Flair integrates with ecobee, Google Nest, Carrier/Bryant, or Honeywell WiFi-connected smart thermostats equally well.
If you have a traditional thermostat Flair will auto-detect the temperature in your vents to know if the system is heating or cooling.
