Current guidance
ecobee retains an ecobee4 installation guide with an HVAC compatibility check. Remote room sensors provide additional temperature and occupancy information, rather than knowing with certainty whether everybody is home. A current ecobee Premium feature is not automatically present on ecobee4. Confirm wiring and system compatibility before purchase or installation; energy savings depend on the building and settings.

Very similar to the Nest Thermostat the ecobee4 replaces your home thermostat. One benefit of ecobee is that is uses sensors in each room to know if you’re home.
