Wifi thermostat for home with two wires to each thermostat

Looking to add a wifi thermostat (e.g. Ecobee, Nest, Honeywell) to a home with just two wires (red and white) running to each thermostat. Heat only. I read 24 volts AC on the wires when they are open


I want to have just one ecobee for the main floor, the other two can remain on dumb thermostats.


Possible?
