Seamlessly (or as close as possible) integrating mini splits and oil boiler?

I have an oil boiler with two zones (one upstairs, one downstairs) each controlled by Nest thermostats.  I'm aware of the Flair/Nest issue and would consider swapping out the Nests for Ecobees or Honeywells as long as the Flair can do what I need it to do.  Cooling is handled by two 1.5 ton Mr. Cool mini-split units, one upstairs, one downstairs.  I currently control those either through the remote or a smartphone app.  

Through reading here a bit it seems that I should be able to control both utilizing a Flair Puck paired with either an Ecobee or Honeywell, but this post:

makes reference to a "Pro Edition" Puck which can only be obtained from a pro dealer.  If I have to swap my Nests out for another thermostat altogether and purchase two new Flair units I'd rather not have to shell out even more money to have an HVAC contractor install a simple thermostat.  Does a regular Puck paired with an Ecobee or Honeywell have the capability to control heating and cooling or must I go with the Pro Edition?

Finally, I also utilize my HVAC controls via Alexa-heat is straightforward of course as I just tell her what zone (upstairs or downstairs) and what temperature I want, but cooling leaves a lot to be desired.  I have the mini-splits named based on the room they are located in to avoid confusion with the heat, but all I can do is turn them on or off and adjust the temperature.  I cannot adjust fan speed, turn on dry mode, or turn off the LED display-those functions can only be executed via the remote.  Will those functions be able to executed through the Puck and/or Alexa via the Puck?
