A Puck set to “Gateway Mode.” A Gateway Puck reads temperature and will send IR commands when paired with an IR device (mini splits, window ac units, portable heaters, etc.).
Every Flair system needs at least one Gateway Puck. It is the hub for your Flair system. Gateway Pucks are powered by AC power, connected to WiFi, and bridge Sensor Pucks and Smart Vents to the internet.
