Nest Thermostat E Review

You know the expression “you have to spend money to make money”? It’s not just something I use to justify spending money aimlessly (although it is also that). It’s also true, especially with smart thermostats. Now, if you already have a thermostat, you might be wondering why you should replace it, and the answer? By sensing motion and body heat, smart thermostats can be as energy-efficient as possible, only making you room comfortable if you’re actually in it.

Don’t believe me? According to an independent study, the Nest Thermostat E can save you anywhere from 10-12% on heating and up to 15% on cooling, making it pay for itself within a couple of years for many people. Not to mention the Nest Thermostat E is just easier to use than a regular thermostat, and I’m excited to show you how.

In this review, I’m going over the Nest Thermostat E’s design, features, installation process, and app before helping you decide if it’s the right smart thermostat for you. I hope you’re staying hydrated, because things are about to heat up!

Save an average of 10-12% on heating and 15% on cooling with the Nest Thermostat E, which works with 85% of 24V systems.

If you’re looking for a sleek and minimalist thermostat, the Nest Thermostat E is a great option. It’s white on white with a 24-bit color LCD screen showing your temperature in 182 pixels per inch. Only a few inches wide, the Nest Thermostat E will work with 85% of 24-volt systems and will probably not require a c-wire. Rather than touching the screen itself, you’ll control the Nest Thermostat E the old-fashioned way— by turning the rim. Of course, there are a bunch of other ways to control your thermostat, but I’ll get to those in a minute.

You can have up to 20 Nest thermostats in your home and three homes per account. It’ll only consume less than one kWh per month, and with a rechargeable battery, installation just got a lot easier. The Nest Thermostat E will connect to the Nest app over Bluetooth and Wi-Fi. Finally, the Nest Thermostat E is ENERGY STAR-certified, meaning that the Environmental Protection Agency deemed it energy-efficient. Sounds great to me!

Now, you probably want to know the temperature in all of your rooms, but having a separate thermostat in every single room would be a little excessive. That’s why Nest also offers the Nest Sensor Thermostat, a small white circle with a diameter of less than two inches operated by battery. You can place the temperature sensor either on a shelf or on the wall, and it’ll communicate with your Nest Thermostat E via a Bluetooth connection. Just place it within 50 feet of your thermostat to easily stay on top of the temperature in different rooms of your house.

To get the most specific information about the temperature in different rooms of your home, you'll need a Nest Sensor Thermostat in addition to your Nest Thermostat E or Nest Learning Thermostat. 

Nest Thermostat E Features

Taking a room’s temperature is really just the tip of the iceberg for the Nest Thermostat E. It can sense a bunch of other useful quantifications, including:

  • Humidity: Let’s be honest, humidity can have a huge effect on how the room’s temperature feels, so I’m glad that the Nest Thermostat E takes this into account.
  • Proximity: The Nest Thermostat E can tell if you walk in front of it, detecting motion.
  • Occupancy: Using infrared body heat, the Nest Thermostat E can check if you’re home and awake, home and sleeping, or away from home.
  • Ambient light: Is it the middle of the night or a bright sunny day? The Nest Thermostat E can sense light and will dim or brighten its screen accordingly.

By taking all of these factors into account, the Nest Thermostat E can tell when it’s appropriate to adjust the temperature to your liking and when it’s not, saving you some major chump change.

Now let’s talk about the different ways you can control the Nest Thermostat E, cause if you’ve read any of my reviews before then you know I love options:

  • Schedules: Let’s be honest: most of us do versions of the same thing every day, so if this is the case, why not match your Nest Thermostat E’s schedule with your own?

  • Geofencing: Connect your Nest Thermostat E with your phone’s GPS so it’ll automatically adjust based on your location. Of course, this method only works if you have your phone with you at all times, which seems to be the case for most people in 2019.

  • Voice commands: With integrations with Amazon Alexa and Google Assistant, you can tell your Nest Thermostat E whatever you want it to do, really useful for children or the elderly who aren’t super tech-savvy.
  • App: Finally, you can use the Nest app to adjust your Nest Thermostat E— we’ll talk about that more in a bit.

Now, aside from Alexa and Google Assistant, you’ll also be able to sync the Nest Thermostat E with other connected devices, having their actions trigger each other. From LIFX to Lutron, from Wemo to Logitech, there’s dozens of connected devices that you can connect with your Nest Thermostat E to make your smart home run smoothly. For example, I like having my heat turn up when my Logitech camera is disarmed, as it means I’m home.

You’ll also be able to add up to nine users to your Nest app so they can have full access to your Nest Thermostat E s well. Want to see how much energy you’re using? Check out Nest’s energy usage report (hint: a Nest leaf means you’re at an energy-saving temperature). For the environmentally-minded, a smart thermostat makes a whole lot of sense.

The Nest App

Like all of the Nest products I’ve reviewed, the Nest Thermostat E can be controlled through the Nest app. It’s also where you’ll add users and get alerted if anything is wrong, like if your home is so cold that your pipes might burst. While Android-users gave the app a nice rating of 3.8, iPhone-users were less than impressed, rating it only a 2.1. As a user-friendly app is tantamount to any connected device, I can’t recommend the Nest Thermostat E to iPhone users.

Recap of the Nest Thermostat E

At $169, the Nest Thermostat E is actually one of the more affordable smart thermostats that I’ve seen, which are usually closer to $200. All in all, I think it’s a great deal, with very few things to complain about.

I’d buy the Nest Thermostat E if you’re looking for…

  • 24-volt compatibility 
  • Integrations with Amazon Alexa and Google Assistant 
  • Humidity, proximity, occupancy, and ambient light sensing 

But it may not be the best choice for you because of the following reasons…

  • Low-rated iPhone app 
  • No touchscreen 
  • Won’t support high-voltage heater
