Ecobee3 vs Nest: The Reviews



With the Ecobee4 now available, it’s easy to overlook its predecessor, but the truth is that the Ecobee3 is also a great example of a smart thermostat.

It begins with the Ecobee3 sensors. If you’ve heard anything about the Ecobee thermostats, then you likely know at least a little about how good their sensors are.

These sensors are able to accurately read a room’s temperature and it can also tell if there are people currently inside of it.

You can rest assured that the sensors are indeed as good as advertised, and as long as you arrange them properly, they will work splendidly and provide adequate temperature control for you and your family.

Also, count on energy reports arriving at regular intervals. You can then use these to determine if you need to make additional adjustments to increase the amount of money you’re saving on a monthly basis.

Ecobee3 and Alexa work together, but if you’ve read an Ecobee 4 review, you likely know that the aforementioned virtual assistant features greater functionality in that newer thermostat.

Even so, Alexa functions well enough with Ecobee3 that you won’t be longing for those additional features.

This Ecobee smart thermostat may not have as many cutting-edge features as the newer items on the market, but it still possesses the capability to work exceptionally well inside your home.

Nest (T3007ES)


The third generation Nest Learning Thermostat wants to make it easier for you to always have the ideal temperature in your home, and it does so by carefully understanding and interpreting your preferences.

It doesn’t take long for this thermostat to gain a good grasp of what you prefer with regards to the temperature levels inside your home.

It doesn’t take that much time to make the necessary adjustment suggested by this smart thermostat, but even so, that is the kind of task that you want this device to take care of on its own.

The designers overlooking that flaw does little to diminish the appeal of the Nest Learning Thermostat though.

It’s a bit more expensive than the Nest Thermostat E, but you’re still getting great value if you choose to purchase this item.

What Qualifies a Smart Thermostat for Energy Star Certification?

As much as possible, you want the devices in your home to be energy-efficient. One sure way to tell if an item can be described as energy-efficient is to look for the Energy Star label.

It is worth noting that the government has specific criteria in place to determine if a particular product is deserving of the Energy Star label, and in the case of smart thermostats the requirements are quite strict.

The requirements are:

  • Has the ability to function as a basic thermostat even when not connected to a service provider
  • Offers feedback for the settings programmed by the user
  • Shares information regarding HVAC energy use
  • It Can be used along with utility programs to prevent brownouts and blackouts
  • Gives users the ability to set a schedule

Smart thermostats are given that coveted certification also have to be highly accurate with their temperature readings, and they should become accessible for users within five minutes of the initial interaction.

These devices also have to meet strict energy savings criteria.

Put it this way, the Energy Star label isn’t just made available to everyone. Companies have to put in extra work to meet the certification standards.

What that means is that you’re getting a quality product if it has the Energy Star label on it. As noted in the comparison table, you will find that label on both the Ecobee smart thermostat that is about to be reviewed and also on the Nest Learning Thermostat.


The smart thermostat that has emerged victorious from the Ecobee 3 vs Nest clash is none other than the Ecobee3.

Ideally, I would love to have the display of the Nest Learning Thermostat but retain all the other features of the Ecobee3, but because that is not possible, I am instead going for the item that gives me a greater return on my initial investment.

There are other reasons to prefer the Ecobee3 over the Nest Learning Thermostat. For instance, if you have already grown accustomed to using SmartThings, I am inclined to think that the Ecobee3 would be more appealing to you.

These are two high-quality smart thermostats being pitted against one another, but in the end, the Ecobee3 comes out on top.
