A Flair system uses WiFi and the Flair network (RF signals). WiFi is used to communicate with the Flair cloud. The Flair network is used for device-to-device communication in your home to route commands and collect data.
Gateway Pucks maintain continuous WiFI connection.
Sensor Pucks that are paired with a mini split will briefly connect to WiFi when downloading the remote codes. Sensor Pucks will also connect to WiFi during an OTA update.
The Flair network is used for device-to-device communication within your home. It's an ad hoc network using RF (radio frequency) signals, similar to Z-Wave and RedLink.
Gateway Pucks act as the hub of the Flair network and bridge other Flair devices to the internet.
Every Sensor Puck and Smart Vent needs to communicate with a Gateway Puck, so Gateway Pucks need to be centrally located.
Flair also uses infrared signals to communicate with mini splits and other infrared-controlled devices, like window ACs and portables.
