Smart thermostats are simple to install and use, but what makes these devices most interesting for consumers these days is how they can help automatically control their home’s temperature through their smartphones.

Tony Fadell, the designer of the original iPod hardware was also responsible for designing the Nest Learning Thermostats, which might be why these products have become so popular. The Nest Learning Thermostat is one of the best looking smart thermostat. Almost 10 years after its initial launch, it is still among the best smart thermostats with a sleek, intuitive design and comprehensive features.

In the following article we will be comparing the Nest E Learning Thermostat to the Emerson Sensi Smart Thermostat.

Nest E Learning

The $249 Nest E Learning thermostat has a well-rounded design reminiscent of old-school thermostats, but it has a modern look that goes well with home decor.

As the name suggests, the Google Nest thermostat is designed in partnership with Google. There are advantages to being part of the Google Ecosystem, as the Nest Learning thermostat both use the same Google Home app. While most of the basic functionality can be completed from the thermostat itself, users will need to use either the Nest app or Google Home for more advanced features..

Programming the thermostat is easy thanks to a user-friendly mobile app. We found it very simple to set schedules using preset options in the Google Home app and found the thermostat as a whole to be intuitive and easy to use. While the current article will focus on the Sensi ST55, don’t hesitate to read our full review of Nest Thermostats.

The ST55 with it’s more than 10,000 reviews is widely regarded as an affordable smart thermostat with high-end features, such as geofencing. In addition, it works with all major voice assistants, such as Amazon Alexa, Apple Siri and Google Assistant. It certainly supports more systems than more other thermostats with compatibility with Apple HomeKit and SmartThings Home Automation platforms. Although IFTTT is not supported, the Sensi ST55 is an inexpensive smart thermostat that is easy to install and works with many home automation and voice control systems


The Emerson Sensi Wi-Fi thermostat provides an easy-to-use app for Android and iOS devices and has a sleek touchscreen design. A pair of sensors are equipped with the device so the thermostat can detect multiple temperature readings and make the appropriate temperature changes.

To make controlling the home temperature as simple as possible, the Emerson Sensi Wi-Fi thermostat connects to your home Wi-Fi, enabling you to control the thermostat from anywhere on the Internet, no matter where you are. It also features seven-day planning, path settings, on-screen weather information, humidity sensors, geofencing and device status alarms. 

Within 15 short minutes, you could already be managing your home’s heating and cooling temperatures. The installation of the Emerson Sensi Wi-Fi thermostat is easy using the Sensi mobile app, which tells you which wires to connect to your old thermostats and configures them with settings that suit your home. As shown in the tutorial, the app also provides instructions on what you need to do to set up your thermostat from the start.

With the Emerson Sensi Smart Thermostat, users will save money with the reliable WiFi monitoring, control and automation. The Sensi Touch thermostat could get a few upgrades in the coming years, but if you don’t mind not having the latest technology features, the Sensi and Sensi-Touch thermostat’s features are more than satisfactory.

The Sensi temperature setting can be set to a precision of one degree, which is usually the industry average for level of detail in temperature control.


Unlike most smart thermostats, the Sensi is not compatible with mains voltages, gravity systems, floor and millivolt walls. If you don’t have a C wire (common wire) in your home heating systems this thermostat works great without it.

The Emerson Sensi Wifi Smart Thermostat lacks some of the advanced tools that other programmable thermostats include, such as automatic scheduling and motion sensors. 

 Even if it doesn’t have motion sensors or automatic timing, it still offers all of the other more important features at a fraction of the price of leading thermostats, including the Nest Learning. The Emerson Sensi Wifi Smart Thermostat comes with a three-year warranty and an impressive mobile app. It is easy to program and provides the best value of all the smart thermostats out there.
