A Flair system requires at least one Puck to act as a communication hub (called a "Gateway Puck"). You may need more, depending on the number of devices in your Flair system and the size and layout of your home.
If you have a large Flair System - more than 13 Smart Vents and Pucks - you'll need to configure multiple Gateway Pucks. For more info, please see our Large System Calculator.
A Gateway Puck is connected to both your home WiFi and the Flair network - a local network of Flair devices communicating over radios signals.
Gateway Pucks bridge Flair devices to the internet. A home may have one or several Gateway Pucks - it depends on your scenario.
A Gateway Puck is configured during Setup. A Puck that is not configured as a Gateway is called a "Sensor Puck". Both can read room temperature.
Gateway Pucks vs Remote Sensors
For central systems, every room with Smart Vents needs a temperature sensor. This can be a Puck (Gateway or Sensor), an integrated smart thermostat, or smart thermostat remote sensors.
If you plan to use remote sensors or Sensor Pucks in rooms with Smart Vents, keep in mind that every Smart Vent and Sensor Puck will need to communicate with a Gateway Puck. Place Gateway Pucks central to these rooms so Smart Vents and Sensor Pucks have a good radio signal to the Gateway Pucks.
NOTE: remote sensors are not part of the Flair network. Flair reads temperature from remote sensors by communicating with your integrated smart thermostat via their API. Remote sensors do not talk to Smart Vents.
