The Ecobee3 has long been our favorite smart thermostat for several reasons. The Alexa integration is obviously key, and we love the fact that it works with a remote sensor so it can adjust your heating and cooling based on the temperature in an area of your house that gets a lot of traffic, instead of whichever random hallway that happens to house your thermostat. The 3 is still a terrific thermostat, and it’s on sale right now on Amazon at its lowest price ever, but there’s a new sheriff in town: The Ecobee4. It’s better in every way — it can even replace your Amazon Echo as an Alexa speaker — and it’s discounted right now on Amazon even though it was just released!

Here’s what you need to know from the product page:

  • Comes with built-in Alexa Voice Service, so you can ask your ecobee to set a timer, read you the news, adjust the temperature, and more. With Far-field voice technology your ecobee4 can hear you from across the room.
  • Room sensors help manage hot and cold spots in your home, delivering comfort to the rooms that matter most.
  • Easily adjust temperature and comfort settings from anywhere using your Android and iOS devices. Also works with Apple HomeKit, Samsung SmartThings, IFTTT and more
  • Save an average 23% on heating and cooling costs each year. Learn more at
  • Fast, easy installation you can do yourself. Use our handy step-by-step guide right on your phone.
