Decouple the temperature and valve in thermostats

Is it possible to control just the valve of my radiator using Home Assistant, without relying on a Smart-Thermostat’s temperature setting? Essentially, I’d like to measure the temperature separately and use Home Assistant to adjust the valve accordingly. Can this be done with any Smart-Thermostats out there?
