Getting started
What you need and how it fits.
How do I know which Flair products I need?
Start with the System Builder. Answer a few questions about your home and how you heat and cool it, and it lists the products you need and where each one goes.
Does Flair replace my thermostat?
No. Flair works alongside the thermostat you already have, smart or traditional, to even out temperatures across your home. With a supported smart thermostat, you can also control the thermostat from the Flair app. See the thermostat compatibility page.
Do I need a smart thermostat to use Flair?
No. Flair works with all thermostats. With a traditional thermostat, or a smart thermostat Flair doesn't integrate with, Flair manages room temperatures by redirecting airflow with Smart Vents. With an integrated smart thermostat, Flair can also control the thermostat for you. Compatible smart thermostats are listed on our compatibility page.
Do I need a Flair Puck in every room?
Every room with a Smart Vent needs a Flair Puck or a supported room sensor, so Flair knows the temperature in that room. For mini splits, use one Puck 2 per indoor head unit, placed in the room that unit serves. You can add a Puck to other rooms too if you want Flair to track them.
Can I install Flair myself?
Yes. Smart Vents replace your existing vent covers, so you only need a Phillips screwdriver and the Flair app. Puck 2 needs no wiring. Step-by-step guides and videos are on the installation page, along with a way to find an installer if you'd rather have it done for you.
Compatibility
What works with Flair.
What is Flair compatible with?
Flair Smart Vents work with central heating and cooling and the thermostat you already have, smart or traditional. Flair is an official integration partner with several smart thermostat and HVAC brands, listed on the thermostat compatibility page.
Puck 2 works with mini splits (ductless heat pumps), window ACs and portable ACs that have a standard IR remote: 275+ brands · 6,000+ OEM IR remotes.
Flair also works with Amazon Alexa and Google Assistant for room-by-room voice control.
Does Flair work with my mini split?
If your mini split has a standard IR remote, Puck 2 works with it. Look at your remote's display. If it shows the settings you're sending, like temperature, mode and fan speed, it's a standard IR remote and Puck 2 can control the unit. Remotes with no display, or a display that only shows temperature (incremental remotes), aren't compatible. Find your brand on the mini split compatibility page.
Do I need my mini split's Wi-Fi adapter?
No. Puck 2 talks directly to your head unit with infrared, just like your remote. It connects to Wi-Fi itself, so you don't need any wiring or the manufacturer's Wi-Fi adapter. Your handheld remote still works alongside the Puck.
Can I use room sensors from my thermostat with Flair?
Yes, if they're supported. Flair works with room sensors from select smart thermostat brands. Each sensor must be paired with a thermostat from the same brand. See which sensors and thermostats are supported on the thermostat compatibility page.
Does Flair work with Amazon Alexa and Google Assistant?
Yes. Flair works with Amazon Alexa and Google Assistant, so you can add room-by-room voice control. See all of Flair's smart home integrations.

Flair Bridge
The Bridge, explained.
What is the Flair Bridge?
The Bridge is Flair's plug-and-play hub. It connects to the internet and passes information between your Pucks, your Smart Vents and Flair hvacOS™ in the cloud. It makes setup simple and lets every Puck and Smart Vent run fully wireless.
How do I connect the Bridge?
Plug it in and connect it to your router with an Ethernet cable for the quickest setup and the most dependable connection, or use Wi-Fi. Then set up and control your system in the Flair app.
Do I need a Flair Bridge?
Central systems with Smart Vents: yes. Every new Flair home with Smart Vents needs a Bridge as its hub.
Mini splits: recommended. Without a Bridge, a Puck runs while plugged in to power. A Bridge lets Pucks run fully wireless, and we recommend one for homes with several mini splits. It also makes setup faster.
How much of my home does one Bridge cover?
A centrally located Bridge covers a home of about 2,500 sq ft and supports 30+ devices. Your layout and building materials affect the range. For a bigger home, add another Bridge.
My system uses a Puck as its Gateway. Do I need a Bridge?
No. Homes that already use a Puck as the Wi-Fi Gateway are still fully supported. If you want more wireless range, have a lot of devices or want battery-powered Pucks, install a Bridge and switch your Gateway Puck to a room sensor.
Smart Vents
Smart Vents for central systems.
How do Flair Smart Vents work?
Smart Vents replace your existing vent covers and open and close on their own to redirect airflow. They fix rooms that run too hot or too cold, balance temperatures across your home and save energy and money along the way. A Flair Puck or supported room sensor tells Flair the temperature in each room, and Flair works alongside your thermostat. See how Smart Vents work.
Do Flair Smart Vents need Wi-Fi?
Smart Vents connect through the Bridge, which connects to your home network with Ethernet or Wi-Fi. If the power or internet goes out, Flair enters a fail-safe mode and every Smart Vent opens. Flair starts back up on its own when power and the connection return.
What is Flair Backpressure Protection?
Backpressure Protection limits how many Smart Vents can be closed at one time. Flair never closes more than 1/3 of the vents in your system, counting every vent in your home, including regular vents. A Lawrence Berkeley National Laboratory study showed this is safe, and Flair adds a 100% safety margin on top of its conclusions.
How are Flair Smart Vents powered?
Each Smart Vent runs on 2 C batteries that last up to 3 years, and the batteries are included. 24VAC wired installation is also available.
What size Smart Vents do I need?
Measure every vent, since sizes can change from room to room. Take off the vent cover and measure the length and width of the duct opening. The vent measuring guide shows three ways to measure and every Smart Vent size.
How many Smart Vents do I need?
It depends on the problem you're fixing.
- One room gets too much air. It's too cold in summer and too hot in winter. Start with a Puck and a Smart Vent in that room.
- One room gets too little air. It's too hot in summer and too cold in winter. Put a Puck in that room, then add Pucks and Smart Vents to the other rooms to push more air toward it.
- Temperatures are uneven across your home. If rooms change with the time of day and the season, add Pucks and Smart Vents to every major room.
The System Builder works it out for your home.
Pucks
Pucks and Puck 2.
Do Flair Pucks need Wi-Fi?
With a Bridge, every Puck connects through it wirelessly, and the Bridge connects to your home network with Ethernet or Wi-Fi. Without a Bridge, at least one Puck in your system connects to Wi-Fi and has to stay plugged in to power.
How are Flair Pucks powered?
Pucks take 2 AAA batteries that last about a year, and the batteries are included. Every Puck also comes with a cable and power adapter, so you can keep it plugged in.
Can I use Puck 2 as a Gateway?
No. Puck 2 can't act as the Gateway for other Flair devices. To connect several Pucks and Smart Vents, use a Bridge.
I already have a Puck (1) set up as a Gateway. Can I connect Puck 2 to it?
No. Puck 2 can't connect to a Puck (1) Gateway. To add Puck 2, install a Bridge and switch your Puck (1) to a room sensor.
