Floor Heating with closet placed Thermostat


I have a house with floor heating on the ground floor. For the upper rooms I'm about to install smart thermostats for each radiator.

For the ground floor I hope I can replace the regular radiator thermostat (that is paced there to control the flow to the floor heating) with a smart radiator thermostat in the cellar yet control in using the main thermostat, overruling the temp measurement of the knob in the sellar.
