what are you trying to control?
You have sensor all over. are you want average all temps and ON/OFF heat/cool based on this average?
there is no method for overide temp on thermostat that I know of but what you may do is create an automation that looks at your temps then adjusts set temp up/down in order to force thermostat ON
basically, thermostat may be looking for 2degree temp drop to turn on cool for example.
if set at 78 and thermostat temp is 78 it not turn on.
if you want cool ON you create automation that shifts set temp down to 76 so thermostat cool turn ON
