Nest Thermostat E Review

If you’ve been craving a Nest Learning Thermostat but a steep $250 price tag, there’s now a more affordable alternative. Nest Thermostat E At $169, the Nest Learning Thermostat does it all: It can be programmed and controlled from your smartphone, and automatically schedules heating and cooling based on your activity. However, it has fewer wire terminals than its more expensive siblings, which means it’s not suitable for homes with complex HVAC systems, and the display isn’t nearly as bright.

Design and Features

The Nest Thermostat E ($169.00 at Newegg) (opens in new window) shares the same disc-shaped design as the Nest Learning Thermostat, but is slightly smaller at 3.19 inches in diameter (3rd-generation thermostat is 3.3 inches in diameter). It comes in only one color (matte white) and uses a polycarbonate casing, while the Learning Thermostat offers brushed black, white, copper and stainless steel finishes and is made of metal.

One of the most obvious differences between the two is the display; The Thermostat E’s LCD screen has a resolution of 320 x 320 and uses frosted glass, providing a softer look than the Learning Thermostat, which has a resolution of 480 x 480. The Nest Thermostat E also lacks the sibling’s Farsight feature, which wakes the device when you enter a room and displays the time and current temperature or weather. E will wake up when you get close to it, but only displays current and target temperatures. In addition, the Learning Thermostat screen is very bright and easy to read from a distance, while the E screen is relatively dim and may be difficult to read for users with less than perfect vision.

Inside the Nest Thermostat E are temperature, humidity, motion, and ambient light sensors, a rechargeable lithium-ion battery, Bluetooth radio, and an 802.11ac Wi-Fi that supports 2.4GHz and 5GHz wireless connections. According to Nest, the E will work with about 85 percent of all 24-volt home heating and cooling systems for hot air, gas, electric, solar, oil, heat pump, and hot water systems. It will support single-stage heating and cooling with secondary heating or cooling (not both), but it does not support multi-stage heating and cooling or plug-ins such as dehumidifiers, such as Learning and Honeywell Prestige IAQ.

Like other thermostats from Nest before it, the E is an educational thermostat and will create a heating/cooling schedule based on your daily activities. It also offers Home and Away modes to save energy, and its Home/Away Assist feature uses your phone’s location services to automatically enter eco mode when you leave home and when you come back, back to home mode (your usual schedule).

Pressing the outer ring of the thermostat activates the on-board menu system. Here you can select heating type (gas, oil, electric, propane), system type (forced air, radiant), set date and time, configure network settings, home / away help, Nest Sense (auto schedule, sunblock), set reminders for changing factors Filter and display energy usage reports. Nest Pro Settings allows you to enter contact information for your HVAC services company.

Temperature settings can be adjusted on the device itself using the exterior color, through the Nest mobile app (Android and iOS), or the web console for all Nest devices, including the Nest Protect smoke alarm and the Nest Cam security camera. The thermostat main screen displays the set temperature, the current room temperature, and the outside temperature. You can use the arrows to increase and decrease the specified temperature or scroll the dial. Below the display is a heat button that lets you turn the heat on and off and switch to eco mode. The “Schedule” button launches a weekly calendar where you can schedule heating and cooling, and the “Record” button starts the daily energy log report.

Clicking the gear icon in the upper-right corner takes you to a menu where you can choose Home / Away Assist, Auto Schedule, Time to Temp (estimates how long it will take you to reach your target temperature), and features including skin can be enabled. (Heating starts early to reach the target temperature at a given time), and sunscreen (tells the thermostat when it’s in direct sunlight, allowing the temperature to be adjusted accordingly). Here you can also set environmental temperature limits, change device information, and configure Wi-Fi settings.

Installation and Performance

I started by removing the existing thermostat, but I took a picture of the wiring for reference. Since I only have a dual-zone heating system (no cooling, unfortunately) I only had to connect three wires to the mounting plate. Wires W1 (heating), RH (power), and C (general). Using the built in level, I mounted the mounting plate to the wall and used the included screws to secure it. Picking up the casing on the mounting plate, the thermostat turned on and displayed the Enter key I had entered into the mobile app. Then I entered my heating system info, chose my Wi-Fi, set my location, and I was good to go.

The performance was great. The thermostat responded immediately to changes made using the app and followed my allotted schedule. Like an educational thermostat, the E created a heating schedule based on my coming and going, and Home/Away Assist never failed to switch modes whenever I left and came back. The thermostat also responded quickly to Alexa voice commands to change the temperature settings.


With the Nest Thermostat E, you get almost the same smart functionality you get with the Nest Learning Thermostat for $80 less. Granted, you don’t get many color options, and the screen isn’t sharp, but the Nest Thermostat E offers the same learning technology for automatic scheduling, uses the same mobile app, and a number of Nest and third-party smartphones. Works with – household appliances. At $169, it’s not as affordable as the Honeywell Lyric T5 Wi-Fi thermostat, but it does offer more features, including usage reports, third-party support, motion and humidity sensors, and support for IFTTT apps. However, if your home uses an advanced multi-stage heating and cooling system and includes components like a whole-home dehumidifier, our editors’ pick, the Nest Learning Thermostat, is still your best bet.
