Editor's note, Dec. 13, 2018: Parent company White-Rodgers has issued a recall for some first-generation Emerson Sensi Wi-Fi Thermostats manufactured in 2014 and 2015. According to the company, the thermostats can be damaged by household line voltage during service or replacement of a heating or cooling system, resulting in a fire hazard. The recall affects approximately 135,000 first-generation models sold in the US and 15,000 sold in Canada. Current models of the Sensi Wi-Fi Thermostat are not affected and are still available for purchase. . The original review, published on Oct. 4, 2016, follows.
Emerson's Sensi Wi-Fi Programmable Thermostat doesn't rely on algorithms, remote sensors, geofencing or any other high-end smarts a la Nest's Learning Thermostat, Honeywell's Lyric or the Ecobee3. In fact, it's really just a basic-looking programmable thermostat with a related app. So, why should you buy it over the competition?
Let me count the ways:
- It's affordable -- The Sensi is widely available at stores like Home Depot for $130 and on Amazon for just $104. Nest and other connected models cost as much as $249. Amazon's UK site lists Sensi for £341 through a reseller, so it's much cheaper and easier to find in the US.
- It's easy to use -- Both the thermostat and the app have thoughtful, logical layouts that make usability a breeze.
- It works with Amazon's Alexa -- You can pair any Alexa-compatible device with Sensi for fast voice control integration.
If you're on the hunt for a thermostat upgrade, but don't want or need all of the fancy extras, the Sensi's semi-smartness still makes it much simpler to heat and cool your home. I definitely recommend it.
Sensi, part one
If I were to come across the Sensi on a store shelf alongside other connected thermostats, I would assume someone put it there by mistake. This thing is pretty utilitarian-looking. It's way better than the 20-year-old, barely functioning model in my house right now, sure, but decidedly lacking in the dazzling design department.
Since the advent of the Nest Learning Thermostat in 2011, a $249 smart model designed by two former Apple employees, a number of manufacturers have turned away from the practical rectangular white box look and have instead tried to add a dose of modern design into the mix.
Emerson didn't do that with the Sensi, but it isn't all bad news -- its buttons are responsive, its display is large and it's easy to read from a distance, as well as different angles. The app and Amazon Alexa integrations, too, are simple to configure and create a number of opportunities for remote access.
But before all that, you have to install your Sensi.
First stop? Check here to see if your wiring is compatible and be sure to visit Sensi's support page if you have installation questions. As always, consult a professional if you aren't comfortable going the do-it-yourself route, but a basic familiarity with thermostat wiring should have everything up and running in minutes. It took me roughly 10-15 minutes, but the holes in my wall from the old thermostat conveniently lined up with the Sensi's, so I took a slight shortcut.
