Nest Thermostat E Review: E is for Everyone

Nest thermostat e

The most recent thermostat launched by Nest is the Nest Thermostat E. The company launched its “diffusion product” with the idea that the new Nest Thermostat E will work wonders for “Everyone”.

The Thermostat is similar to many of the company’s previously launched products in terms of quality and service, excluding a few dispensable features here and there.

However, what the Nest Thermostat E lacks in innovation, it compensates for in its pricing domain. The company has priced the Thermostat at approximately $80 less than the flagship Nest Learning Thermostat 3rd Generation, making it an attractive alternative to expensive thermostats for a majority of newcomers with budding smart-homes.

The Nest Thermostat E, with its easy-to-install and set-up approach, has made professional installation obsolete. Forgoing some superfluous features, the product manages to maintain its predecessor’s user friendliness along with its energy-efficient outlook.

It comes equipped with Temperature, Proximity, Humidity, and Ambient Light sensors to help deliver an unprecedented user experience.

Nest Thermostat E Advantages & Disadvantages

The availability of a free Android and iOS compatible thermostat controller application makes the Nest Thermostat E a worthy investment.

A compact and attractive design along with an extremely easy-to-use interface at an unimaginably reasonable price only adds to the prevailing charm of the product.

Unlike the Nest Learning Thermostat, the Nest Thermostat E does not necessarily call for professional installation. The entire installation process is included in the Nest app which you may follow to install the Thermostat all by yourself.

The device is compatible with most, if not all HVAC systems. The Nest Thermostat E comes with a pre-programmed schedule, based on the data collected from the existing users of Nest’s other products. Additionally, the Thermostat learns to make minor adjustments in its program to suit individual heating and cooling requirements of its users.

You may separately install remote sensors if you wish to monitor the temperature in rooms other than the one where the Thermostat has been installed. The product also provides you with timely Energy Reports so that you may keep a tab on your heating habits and alter the same to suit your energy budget.

Unfortunately, the Nest Thermostat E doesn’t work with the Apple Home Kit. Another disadvantage would be the absence of occupancy sensors in remote monitors.

This directly impacts the amount of energy being conserved by your smart thermostat as heating of unoccupied rooms becomes difficult to control. Hot water support is also missing.

The absence of zone-specific heating can lead to abrupt discrepancies in the temperature profile being maintained in your house. In areas located far away from the location of your Nest Thermostat E, heat regulation becomes quite challenging as the latter fails to take into account the temperature variations observed in different rooms of your house.

This causes a temperature drop to occur in rooms located at a distance from the Thermostat as a temperature reading of 22 degrees in your living room prevents the latter from heating distant areas.

Nest Thermostat E Design & Other Specifications

The Nest Thermostat E is compactly designed in a round puck-like shape. While the Thermostat gives a staggering ceramic feel, it is actually made up of strong polycarbonate material.

The product comes only in a bland white color with a frosted plastic display, similar to many other products available in the market.

The Nest Thermostat E easily blends with light colored walls and offers a lower resolution of 320 x 320 pixels in contrast to the 480 x 480 pixels offered by similar Nest products which makes the display a little sub-standard but at the same time, manageable.

The Nest Thermostat E has proximity sensors and displays the set and current temperature as you approach it. However, unlike the Nest Learning Thermostat, it does not display the date, time or weather.

The packaging includes a matte white ring with a clear plastic overlaid on the display, a base unit to plug the Thermostat’s wires, an installation guide, a pair of mounting screws, and a trim plate to cover visible old holes, thereby giving the newly installed Thermostat an extraordinary finish along with stickers to label the wires.

The Nest Thermostat E has a diameter of 3.19 inches, is 1.14 inches deep and weighs approximately 139 grams. It contains built-in rechargeable lithium-ion batteries and requires an average bandwidth of 50MB per week upload and 50MB per week download.

Nest Thermostat E Installation

The installation process for the Nest Thermostat E is fairly easy for a compatible HVAC system. Nest Thermostat E is compatible with 24V cooling and heating systems.

Nest claims that the Thermostat E would be compatible with 85% of the systems. The provision for checking Nest Thermostat E’s compatibility with your existing system is available at

After unboxing the Nest Thermostat E, take a picture of its wire connections and check for compatibility. The compatibility checker detects if there are any stranded wires, or if there are thick wires with wire nuts, or if the thermostat is labeled 110/120V. In circumstances where any of the aforementioned conditions prevail, the Nest Thermostat E fails to work.

The Nest Thermostat E has a built-in level for easier installation and push-in connectors for screwing the wires which makes the installation process easier for everyone. The mounting screws with wide threads eliminate the need of plastic anchors and get aptly secured into the drywall.

Following is a summarized version of the installation process for Nest Thermostat E.

In the beginning, you must turn off the power from the breaker box. This is important to prevent a potential blow out of the fuse.

When you’re done, try changing the temperature using your existing thermostat and wait for at least 5-7 minutes in order to make sure that the power has been successfully killed. Next, pull off the old thermostat to make the connecting wires visible, and using the labels included in the package, label the wires appropriately, then, unscrew the old baseplate to install your new Nest Thermostat E.

Remember, stranded wires aren’t compatible with the Thermostat. Lastly, hook up the wires to their respective connectors and attach the display unit on top of the base plate.

Once the installation process is complete, you can then set-up the Nest Thermostat E. Nest provides a mobile app for controlling your Smart Thermostat.

Nest Thermostat E Setup

The setup process for the Nest Thermostat E is just as simple as its installation process. All you need to do is provide the system with basic inputs about yourself along with your cooling and heating preferences.

You can also make your thermostat more integrated by connecting it to your Wi-Fi. Follow the steps given below in order to set your Nest Thermostat E.

Select the language of your choice by rotating the outward ring and push the button on the display to confirm your choice. Next, connect to the internet by entering the password. Additionally, input your location and go through all the available options. Finally, regulate your optimum temperature of use.

The Nest Thermostat E operates in two modes: Auto Schedule Mode and Basic Schedule Mode. In order to control the Thermostat using your smartphone, installation of Nest App is required.

Active users need to login to their accounts while new users need to set up a new account. Quick-Shortcut buttons located at the bottom of the screen making it even easier to maneuver through frequently used features.

Nest Thermostat E Features

The Nest Thermostat is nothing if not all about its app. Like a true blue smart product, it can be completely controlled by its users with a twitch of a finger. The Nest Thermostat E offers most, if not all, features available to users on most standard Nest thermostats.

Some of its user-friendly features have been discussed below.

Auto Schedule

The ‘Auto Schedule’ mode can be configured only after manual data has been fed into the system using the ‘Basic Schedule’ mode. The Nest Thermostat E selects optimum temperature requirement based on the previous manual inputs of temperature given by users and tries to match your heating and cooling preference.


‘Time-to-Temperature’ estimates the time required to reach your set temperature. Users must realize that setting higher set temperatures does not increase the pace at which the room-temperature rises.

It only keeps your thermostat running for a longer duration, thereby wasting energy. It’s best to set the Target Temperature as the one that you desire and not at a higher value.


The ‘Early-On’ feature enables the thermostat to start a little early so as to ensure that it reaches the set temperature on the pre-scheduled time. ‘Cool to Dry’ feature has been suitably installed for humid regions. It controls excessive humidity in the room by using the air-conditioner.

The ‘Airwave’ feature, in stark contrast to the ‘Cool to Dry’ feature, is activated when the indoor humidity falls below a threshold and helps maintain it. It stops the air conditioner’s compressor but keeps the fan switched on once the desired temperature has been reached.

The Nest Thermostat E sends notifications about the house’s energy usage and alerts in case the furnace filter needs to be changed. You can also set- up a reminder to change your filter. The safety temperature input in the device works as an extra layer of protection against unexpected temperature variations.

The Nest Thermostat E activates heating if the temperature drops below the set minimum temperature, and begins cooling if it exceeds the set maximum, even when the Thermostat is switched off.

Lock option

With the ‘Lock’ option, you can set a four-digit lock-code and provide a limited range within which you would like to adjust your temperature. In order to change the temperature beyond this set range, one would need to enter your set password.

The Nest Thermostat E also includes numerous energy-saving features. The Home/Away Assist is an energy-conscious feature that utilizes your smartphone for geo-fencing and automatically adjusts the house temperature to ‘Eco Temperatures’, a term referring to the temperature set when you are away, thereby saving energy in the process.

The Nest Thermostat can even reduce the energy consumption by regulating the heating in the presence of sunlight in the room.

The ‘Leaf’ feature shows a green colored image that appears when your thermostat has been adjusted to energy-saving temperatures. Hence, this smart device not only gives its users better control over their thermostat but also fulfills the basic expectations from a smart thermostat, i.e., energy saving.

Nest Thermostat E can be easily integrated with various smart devices such as Alexa and Google Home, giving you voice control over temperature, mode, and other settings.

Nest Thermostat E can be controlled by Alexa or Amazon Echo device. Search for ‘Nest’ on Alexa’s skills and click on ‘Accept’ to enable it. This will link your Alexa account to your Nest account. Click on the ‘Discover Devices’ tab, then find and select your Nest Thermostat to add it.

Availability of an IFTTT channel allows for the activation of secondary devices in cases when the temperature exceeds the set maximum or falls below the set minimum.


The Nest Thermostat E is a one-stop-solution for people looking for a low-budget smart thermostat equipped with a plethora of user-oriented features combined with an attractive design and a strong built.

If you can manage your heating habits without a few luxury features, the Nest Thermostat E can be a good option to consider. The Nest app is simply remarkable when it comes to offering consumers convenient control over the product.

You may remotely control your heating and cooling cycles, create custom schedules, generate Energy Reports, switch between the various available modes, etc. using the Nest app. Also, the ‘True Radiant’ feature prevents overshooting of the temperature by making advance calculations of the time taken by your system for warming up and consequently turning off the boiler before-hand.

The Nest Thermostat E’s ability to take voice commands using Amazon Alexa or Google Home make it an exciting smart-device to get installed in your smart-home.

The fact that Nest finally released an affordable thermostat already has a lot of its consumers looking forward to upgrading their existing thermostats.
