- ELIMINATE UNEVEN ROOM TEMPS & GET ROOM LEVEL CONTROL: Flair Smart Vents work with central systems to bring precise airflow & intelligent control for heating/cooling your smart home. They use smart thermostat and temperature sensor data to automatically open and close vent registers to heat or cool the right rooms at the right time.
- THE PERFECT FLAIR SYSTEM: Flair Smart Vent systems require a Flair Bridge to operate (sold separately). Every room with Flair Smart Vents needs a temperature sensor. Use a Flair Puck (sold separately), integrated smart thermostat, or compatible room sensor.
- INSTALLATION, SETUP & SUPPORT: Replace wall, ceiling and floor vents. No drilling or wiring. Simply take out your old vent and drop in Flair. Flair's app will guide you through step-by-step instructions to connect your devices and complete setup. Flair has a dedicated support team to assist, available 9am-5pm ET (Mon-Fri). Reach us by email, phone or chat.
- POWERED BY SOFTWARE: Control your system from anywhere with Flair’s hvacOS. Use 7-Day scheduling to set individual schedules for each room, and mark rooms as inactive to save energy and money.
- COMPATIBILITY: Flair works with your existing thermostat (smart or traditional) to give you room-by-room temperature control. Flair also works with voice assistants to add simple room-by-room voice control.
