You do not need three full smart thermostats.For single HVAC with dampers, get one primary smart thermostat ~$175–250 ecobee Premium + two ecobee SmartSensors or compatible remote sensors for the other zones total under $400 and fully HA I ntegrated.
So, if I get an ecobee premium, it will be smart (and connected) enough to control 3 zones? I’m assuming that there would be wiring for N number of zones? How’s that work?
I’ll be doing the wiring myself, so I REALLY need to understand this.
