    Hi David,

    Flair supports multiple thermostats and sensors so no worries there :)  In most homes a single Puck is all thats needed if you already have enough remote sensors however if you have 3 separate hvac systems, my guess is that you might have a pretty large home/deployment.  You can punch in the number of Vents you'll need here and then it will calculate how many gateways you need:  https://flair.co/pages/large-systems

    Cheers,

    Thank you for the great response.  I have since purchased my first Flair puck (gateway) and several vents.  Upon exploring the system I have another, related question...

    I have three HVAC systems in the house, one on each floor (basement, first, and second floor).  Each has it's own Ecobee thermostat.  Flair has recognized all of this with one gateway puck and seems to be working properly.  However, in my house my basement is constantly warm due to some equipment which generates a lot of excess heat.  This means that even when I need heat on the first and second floors, I still need cooling in the basement.

    In the Flair system it appears that I need to set the entire system to one mode (heat/cool/auto) which affects all of the thermostats it knows.  I have created three zones (one for each HVAC system and Ecobee thermostat) and put the various rooms, sensors, and thermostats in those zones.  Is there a way to have one zone be in cooling mode while another is in heating or auto mode?  Do I need a separate gateway puck and a separate home setup to separate these?

    Again, I appreciate all the help.  I wanted to find the right way to do this before I purchase more equipment to manage my basement temperature.

    Thanks again!

    So, to add one more complication to my setup, I would like to let the Ecobee thermostats control the mode, setpoints, and schedule if possible.  That is how I have them set now with the first Flair equipment I installed on the second floor.  After reading the article https://support.flair.co/hc/en-us/articles/360049600871-Mode-Switching-Explained, I am wondering if letting the Flair system do the setpoints, schedules, etc. will solve this problem of heating one zone while cooling another?

    Thanks.

    Hi David,

    When Mode switching, Flair will make a determination for the whole home - regardless of how Set Point Controller is set. If you want your basement to be in a different Mode than the rest of the home, I'd suggest making a separate Home for the basement. You can still set Mode to Auto Heat/Cool, but it will make a determination for only that Home.

    1. Remove the integration for your ecobee in the basement:

         In the Flair menu, go to Home Settings->Integrations, tap the integration, and then select "Remove Integration".

    2. For each Flair device in the basement, remove it from the home:

        In the Flair menu, go to Home Settings->Flair Devices, tap the device, and then select "Remove Device from Home"

    3. Remove each basement room:

        Tap the 3-dot menu on the room tile, go to Settings, and select "Delete Room" 

    4. Do a "Factory Reset" for each Puck (in the Gear menu)

    5. Add a new home:

        Tap the PLUS sign, select "Add new Home", and follow the prompts to add the new Gateway Puck, ecobee, and Smart Vents.

    Meanwhile, I'll add a feature request for allowing different Modes at one time in a Home. Keep in mind that all feature requests are prioritized by management for inclusion in the product.

    All the best,

    Finn

    Hi David,

    Hang tight. I might have been too hasty in my response and might have an alternate solution.

    I’ll report back once I learn more.

    Quick question: do you want to force one zone to be in a different mode, or let Flair handle the switching based on the set point?

    All the best,
    Finn

    Finn,

    I am open to both scenarios.  My first thought was to be able to put different Ecobee thermostats (i.e. Zones) into different modes (heat/cool/auto).  I think this goes along with your first suggestion that I need to create another "home", one for the first and second floors, and one for the basement.  However, I wasn't clear if I would need a separate gateway puck for each "home" or if one gateway puck can be used for multiple "homes".  It appears when I try to setup a new home that the setup process wants to reset the gateway puck so I have a suspicion that I will need a gateway puck for each home.

    Second possibility is to let Flair handle switching modes based on set points.  It sounds like I could do that all with one "home" based on your last posting.  The only thing I would lose is the scheduling and comfort settings I have setup in the Ecobee environment but I think the Flair system has equivalent capabilities to replicate that.

    Thank you again for the help.  I am getting ready to purchase the hardware for the basement so I appreciate the quick response and help you are providing.

    One more point to clarify... It sounds like you are saying the smart vents have a temperature sensor in the vent itself that can determine if the system is blowing hot or cold, is that accurate?

    Hi David,

    I confirmed with engineering that you'll be able to do this with one Home and integration with your ecobee. Here are the recommended settings:

    • Three ecobees integrated with Flair
    • Rooms assigned to their correct zones
    • Set Point Controller set to "Thermostat"
    • Mode set to "Auto Heat/Cool"

    All the best,

    Finn
