can I customize how room thermometers might control HVAC fan?

I have the nest thermostat and i'm considering getting some nest thermometers.. one for the baby's room specifically which is just a little bit drafty in winter and warm in the summer. 

i know that if the fan were to run it would circulate the air and even out that temp difference.

What i want to know is if i could put a nest thermo sensor in that room, and customize it to automatically turn on the central HVAC fan whenever the temp in the baby room gets above a certain temp in the summer or below a certain temp in the winter? I do have a portable heater with thermoregulating smart plug which i will use in the winter which solves this issue i think... but buying any sort of air conditioner to cool that room in the summer is just very expensive.

I guess it might be enough to just put a thermosensor in that room and then make the nest thermostat use the baby room temp as the primary trigger for running the HVAC sensor. Or is it possible that the thermostat can be set to turn on the AC when EITHER room gets above 73 deg F for example?

Open to any suggestions anyone might have! 

Thanks so much,

New Father.

In order to do what you are wanting to do requires an HVAC system upgrade. You would need to install a Zone Controlled VRF HVAC system. Using Nest remote thermostat with your current system, would signal the system to turn on, but it would cool or heat the entire home.  If all you need to just move the air around, just program the FAN to cycle on and off for say 15 minutes every hour.  The Nest Remote Temperature sensors can be programmed on a Nest E or Nest 3rd generation learning thermostat and do kind of what you need.  You will have to change the programming; the nest can only prioritize a singe temperature sensor as a gatekeeper so to speak.  You would program which remote sensor has control and what times of the day.  

Think of the concept like this. You have a Nest 3rd Generation Learning thermostat in middle of the house. You put a Nest Remote Temperature sensor in the Master Bedroom, the Baby’s room, and the Family Room. At 8PM, the MBR has control, at 7AM the Family Room has control, at 1PM the baby’s room has control.  So when your sleeping, Mom and Dad stay comfortable.  When your up and in your family room, your staying comfortable there.  And when the baby has the afternoon nap, yes, that is were the control is. Now then, where ever the control is, the other areas might be too warm or too cool depending on the mode the system is programed for and which temperature sensor is the primary controlling point.
