    What is the Emerson Sensi Touch Smart Thermostat?

    Smart thermostats are tasked with the responsibility of checking your home’s temperatures. They bring the convenience that they can control the temperatures from anywhere. The Emerson Sensi Touch Smart Thermostat is no different as it does that and much more. You get an interactive LED screen and smart home integration capabilities up and above what conventional thermostats offer. What more does the Sensi Touch Smart Thermostat have to offer? There’s only one way to find out.

    Design and Features

    The Emerson Sensi Touch Smart Thermostat comes with either a black or white glossy finish, which gives it a unique kind of attractiveness. The device has a considerable bezel all-around the gorgeous 4.2-inch color touchscreen. The package comes with mounting hardware, an installation guide, a welcome guide, HVAC wires labels, and an embedded Wi-Fi radio to connect to your local Wi-Fi.

    The thermostat is compatible with single and multi-stage electric, gas, and oil HVAC systems. It is also compatible with systems with heat pumps and central air control mechanisms.

    You’ll need a ‘C’ wire for wiring purposes, so you’d want to confirm with your wiring before you begin with the installation.

    The Emerson Sensi Touch Smart Thermostat will work perfectly with Apple’s HomeKit and Samsung’s SmartThings home automation systems. Moreover, the thermostat can be controlled using Apple Siri, Amazon Alexa, IFTTT applets, and other smart home devices.

    The Emerson Sensi supports geofencing, which will adjust your temperature based on your location's climatic specifications. The thermostat can also send push messages if you set it to do so when temperatures go above or below a certain threshold. If you have severe heating/cooling issues, you'll also receive push alerts.

    With the help of the Sensi mobile app, you can schedule your heating and cooling for, say, a week. However, the thermostat doesn’t have remote room sensors, a feature available in higher-priced thermostats.

    Great Interactive Screen

    The screen remains dimmed till you touch it. You can check the current room temperature displayed at the center in white numbers against a gray background when it lights up. When the thermostat is heating the house, its background turns orange. When cooling, the background turns blue.

    You get a 'Set to temperature' tab on the right with top and bottom-facing arrows for adjustment. The current temperature is displayed to the left, and the humidity is displayed right below it. The bottom side of the screen shows the various operating modes (Aux, Cool, Heat and Auto). You also get fan mode indicators around the same section.

    The top-left corner houses the menu button, which also takes you to where you can access the settings. You can toggle around with LED (back glow) settings, sleep mode Wi-Fi, date and time settings, creating cooling and heating schedules, etc.

    The advanced settings concern the circulating fan and dehumidifier.

    Advanced Features

    The thermostat indicates the current area’s weather at the top, with the highs and lows. A scheduling button also helps you create cooling and heating schedules over a specified time. There's also a section where you can view your usage reports; on the usage button.

    Other controls let you set temperature limits, enable and disable geofencing, change passwords, change profile information, set reminders and push information, set up emails, access the online help center, etc. You can also sign up for energy-saving programs and check your thermostat’s firmware update information.

    Installing the Emerson Sensi Touch Smart Thermostat

    Everything about installing the Emerson Sensi Touch Smart Thermostat is pretty straightforward. You only have to use low-voltage wires. If you aren't good with electrical wiring, kindly get a professional to handle it. Nonetheless, you can also watch a tutorial video guide.

    Afterward, download the mobile app (compatible with Android and iOS) and connect it with your thermostat for mobile operation. Of course, you'll need to create an account and register your thermostat.

You only need to set the desired temperature ranges to stay within. Now sit and watch the Sensi Touch Smart Thermostat will do everything else for you.

    Is the Emerson Sensi Touch Smart Thermostat worth buying?

    Yes! If you need a reliable thermostat, the Emerson Sensi is hands down one of the most reliable choices. Its design might be the only downfall we're seeing, but why would you write off a top-notch thermostat for a lacking design? Emerson Sensi thermostat’s smart home integration is insane, and you’ll be able to control the temperature by word of mouth – I’m talking about Google Assistant, Siri, and Alexa.

    Above all, the capacitive touchscreen is satisfyingly responsive to touch and displays much information at a glance. The setup and configuration, and ease of operation of the Sensi Smart Thermostat will go unbeaten for long.

    Comparison: Emerson Sensi ST55 vs. Honeywell Wi-Fi 7-Day Programmable Thermostat

    Let's compare two of the most popular budget thermostat brands; the Emerson Sensi Touch Smart Thermostat and the Honeywell RTH 6580WF. They come with Wi-Fi connection and smartphone integration and still manage to be among the best-priced thermostat models. Let's look into what they have to offer and highlight their differences.


    The Sensi Smart Thermostat is far ahead in setup and configuration. When it comes to installing the software, creating a user account, and running it. Unfortunately for Honeywell, the app appears to 'assume' you already have an account. You'll have to create an account and access it via the 'Forgot Password' section on the website. You'll be prompted to enter your location manually, which won't be anywhere near friendly for you. Entering your device's Mac ID is also tedious, and you'll be done in almost an hour, something that won't take your time on the Sensi thermostat. You'll either scan a QR code or be prompted to provide an email and password to create your account on the latter—such a breeze.

    When it comes to the thermostats’ hardware look and feel, Emerson Sensi comes on top again. Both devices have a ‘somehow-rectangle’ look and have huge buttons that are easy and comfortable to push. However, the Sensi thermostat has a more defined rectangular shape, and its controls are flatter and have a sleeker look. The device looks more modern than its counterpart, the Honeywell thermostat. The green illumination on the Honeywell might look better than Sensi’s white glow.

    When we compare the app companion design and usefulness, Sensi easily wins, again! Both thermostats are run through their mobile apps, which increases efficiency and saves you the effort of adjusting everything from the device. However, when you open both mobile apps side-by-side, you'll notice that Honeywell's interface is cluttered and has so much information, while Sensi’s screen has just enough detail and looks a bit more modern. Again, as opposed to Sensi’s unlimited adjustment periods, Honeywell offers only four.

    Here’s a comparison table to highlight the distinctive differences.

    1. Will my Sensi Thermostat work without Wi-Fi?

    Yes! If you had set a heating or cooling schedule, the thermostat would continue working without a Wi-Fi connection. Sensi thermostats are designed to work even without a Wi-Fi connection.

    1. What is the lifetime of the Sensi Thermostat’s batteries?

    A year. The batteries should last a year, and there's always a battery-level icon on the screen to show which level you’re currently running on.

    1. What does the AUX on the Sensi Thermostat mean?

    The Aux means the heat generated from a secondary source. It is taken to mean an Auxiliary heat source. An auxiliary heat source is less cost-effective than a heat pump on most occasions. Therefore, it needs to be used ONLY when you must reach a certain set point in Heat Mode.
