The Good The Ecobee SmartThermostat adds features to its built-in Alexa speaker. It has a redesigned temperature sensor and works with Google Assistant and Siri — all for the same $249 price.

The Bad Depending on where your thermostat is located in your home, it might not be in an ideal place for an Alexa speaker.

The Bottom Line Ecobee’s SmartThermostat is a solid device that’s well worth considering if you want a connected thermostat with a built-in Alexa speaker.

he SmartThermostat with Voice Control is Ecobee’s new high-end smart thermostat. At $249 (including one temperature sensor), the price is steep, but Ecobee gave this model some additional smarts that make it worth considering. The Ecobee4 will continue to be sold for $249 as long as supplies last, and while the new model isn’t the most dramatic upgrade over the previous one, it has a the following additional features that make it more compelling:

  • A glass, rather than a plastic finish
  • Support for 2.4GHz and 5GHz Wi-Fi, rather than just 2.4GHz
  • Digital rather than analog microphones (this allows for better Alexa integrations)
  • Improved speaker quality
  • A redesigned temperature sensor

You can’t see the majority of these things by looking at the Ecobee SmartThermostat, but they do make it easier and more enjoyable to use overall.

If you already have the Ecobee4, I wouldn’t run out and buy this model, since they’re very similar. But if you’re interested in a solid smart thermostat with a fully functioning built-in Alexa speaker, Ecobee’s latest iteration is your best bet.
