Ecobee Smart Thermostat Premium
What works
- Built-in air quality sensor (VOC + CO2) alerts you when indoor air quality degrades — no extra device needed
- Zigbee hub integration allows it to control compatible lights and locks directly
- SmartSensor remote room sensors average temperature across rooms — solves hot/cold room imbalance
What doesn't
- At $249, it costs $100 more than Nest Thermostat for features most people won't use
- Ecobee's UI feels clinical and menu-dense compared to Nest's rotating dial and learning-curve-free setup
- Remote sensors sold separately at $79 for a 2-pack — the full system gets expensive fast
Google Nest Thermostat (4th Gen)
What works
- Learning schedule builds itself in 5-7 days — genuinely zero-configuration for typical households
- Nest Energy History shows exactly when your HVAC ran, what it cost, and why — best energy reporting of any thermostat
- Mirror display blends into a wall and shows ambient information on approach — cleanest design in the category
What doesn't
- No C-wire adapter included — many older homes need a professional install to run a C-wire
- HomeKit is conspicuously absent — Google and Apple play cold, iPhone users get a second-class experience
- Learning algorithm occasionally makes wrong assumptions — manual correction needed for irregular schedules
Bottom line
Our pick: Ecobee Smart Thermostat Premium.
