To add more Smart Vents to your home, navigate to the Flair App on your browser or device. On the App home screen, click the + button, followed by Add New Flair Devices.
After a few minutes, you should see a unique pattern on the Smart Vent Light Bar. A matching Smart Vent (with the unique pattern) will also appear in the App. Assign the new Smart Vent(s) to the appropriate room(s) and exit out of setup mode.
