Which Should You Buy?
Our Verdict
If you want a thermostat that programs itself and looks like a piece of design, the Google Nest Learning Thermostat (4th Gen) is the pick. If you have rooms that run hot or cold, want broad platform support including Apple HomeKit, and like the idea of a built-in voice assistant and air quality sensor, the Ecobee SmartThermostat Premium is the more complete package out of the box.
Want to compare a third option? The Honeywell Home T9 Smart Thermostat is a strong alternative with optional room sensors. For a touchscreen, Alexa-ready option, also consider the Honeywell Home Wi-Fi Smart Color Touchscreen Thermostat.
Tip: Whichever you choose, confirm your HVAC wiring has a C-wire (or use the included power adapter) before installation — our smart thermostat buying guide explains how to check compatibility to ensure stable, continuous power.
Frequently Asked Questions
Does the Google Nest work with Apple HomeKit?
No. The Google Nest Learning Thermostat does not support Apple HomeKit or Siri. If HomeKit is a priority, the Ecobee SmartThermostat Premium is the better fit, and it pairs well with a hub like the Apple HomePod (2nd Gen).
Which one saves more energy?
Both can deliver meaningful savings. Nest leans on automatic learning to optimize your schedule (see our Nest Learning Thermostat 4th Gen review for real-world results), while Ecobee uses its included room sensor and occupancy detection to avoid heating or cooling empty rooms.
Does the Ecobee have a built-in speaker?
Yes. The Ecobee SmartThermostat Premium includes a built-in Alexa speaker, so it can answer questions and control smart home devices without a separate Echo. The Nest does not have a speaker.
Do I need extra room sensors?
The Ecobee includes one SmartSensor in the box, while Nest sensors are sold separately. If your home has uneven temperatures between rooms, sensors significantly improve comfort.
