    Hi Taylor,

    I see you want to cool the upstairs by redirecting cool air from the main level to the bedrooms at night. You have the right idea of putting the Smart Vents downstairs. I'd place the Puck downstairs too because all the Smart Vents need to connect to it using RF (radio frequency) signals. Putting it upstairs might be too far out of range for all the Smart Vents. Flair can use the temperature from the ecobee remote sensors you have in the bedrooms to know when to close the downstairs Smart Vents.

    Since you have an open floor plan and no Smart Vents upstairs, we can create two "rooms" in Flair: Upstairs and Downstairs. You'll assign all the bedroom ecobee remote sensors to the Upstairs room, and all the Smart Vents and the Puck to the Downstairs room. (When you get Smart Vents for the bedrooms to handle winter heating needs, you can break out the Upstairs "room" into individual rooms to get better control over room temperature.)

    We want to prioritize airflow to the bedrooms at night when you're using them the most. For this, we recommend a Flair schedule that sets Downstairs to Inactive during sleeping hours sets the Upstairs Inactive during the day.

    There's another setting that Flair uses to control where the home temperature comes from. The "Set Point Controller" (found in Home Settings->System Settings) can be set to "Thermostat" to read the temperature you set on the ecobee. You can create a comfort setting on the ecobee that uses the remote sensors in the bedrooms at night. This will keep the AC on long enough for the Smart Vents to open and redirect cool air to the bedrooms.

    If you have more questions about the operation of your system, please direct them to so our Support Team can respond more quickly to your questions.

    All the best,

    There's lots of ways you can set this up.  Depending on if you want the Ecobee or Flair to make decisions about when to run the HVAC.

    If I was doing this, I would move the Puck downstairs so it's in the same "room" as the vents.  I would plug it in and just put it on a table/counter somewhere in the large open space, so it's closest to the most vents in this space.  I would NOT integrate the Ecobee and Flair systems at all.  Just have them function independently.

    For the Ecobee, I would set a schedule and which sensors to use for that schedule based on which sensors you want included in it's averaging math.

    For Flair, I would define 2 rooms, one with the unconnected Thermostat and one for the "room" with all the vents in it.  Set a schedule for the temperature you want that room to be at in Flair.  Flair will then open close the vents to get to this temperature, but since it's not integrated with the Ecobee it will not be able to turn the HVAC on or off.

    Not being able to control the HVAC will not matter, since the other rooms are really driving the Ecobee to run or not.  They're always behind the big room in changing temp.  The Flair puck will open and close the vents as the big room gets there first to cut it off, or when it needs some air.


    I'm using the system exactly like this in my house, only it's the basement that's the room with all the vents and get's cold first then closes.  I have some bedrooms set up this way too.  My Ecobee and sensor are mostly based on the one room that's always last to cool or heat.  That lagging room drives the HVAC status and the Flair opens or cuts off the areas that get to temp first.  On the plus side, when the kid sets their bedroom puck to 60, it doesn't drive the HVAC.  It just never closes that vent when cooling.  It also doesn't include in the heating average either then, just stays closed all winter in that bedroom.
