You need at least one Flair Puck in a Flair system. This Puck is configured as a Gateway and plugged into power using the supplied cable and adapter. The Gateway Puck is connected to your home WiFI and bridges all your Flair devices to the internet (even if you only have one Puck in your system).
For mini splits, window AC's and portables, you'll need one Puck per unit. For mini splits, this is one Puck per indoor head unit.
Large Systems: For large systems with more than 11 Flair devices, use the Large System Calculator to determine the minimum number of Gateway Pucks required for your home.
Pro Tip: For systems where a visible wire is not desirable, we recommend using a Puck as a dedicated networking device. This Puck is plugged in to a convenient outlet and connected to home WiFi. This frees up other Pucks to use batteries.
Note: Based on layout and construction, some homes will require more than one Gateway Puck to facilitate signal to other Flair devices.
