I am looking for a smart thermostat with additional temperature sensors

I have two separate AC and heating units with two thermostats in my office. I am looking for a thermostat I can lock at a specific temperature that has temperature sensors. One area gets too cold while the room with the thermostat stays perfect, and the warehouse has a similar issue. Managing these zones manually is very costly. It would also be nice if I could control them using the same app. Any recommendations?
