What Makes a Smart Thermostat Smart?

You’re probably wondering what makes a thermostat smart as opposed to just being a regular thermostat. Is it just that these thermostats are connected to Wi-Fi or that you can control them from nearly everywhere? These are part of the overall equation that makes them smart, but it’s not the entire picture.

It’s not even that smart thermostats are programmable. There are plenty of non-smart thermostats on the market that have 7-day or 5-2 day programming options with multiple events per day. (An event is when the thermostat knows to change the temperature in your house. Like you leaving for work is considered an event. That is because the thermostat lets the house warm up in the summer or get colder in the winter to save energy.) It’s not even the neat geofencing technology that lets the thermostat know where you are and adjust automatically.

It’s all of these things that combine to make your thermostat smart. You can control it from nearly anywhere, whether it is through your smart device or just by telling Alexa to turn the heat to 76 degrees. And when you pair it with a smart home hub like the Apple HomeKit, you can integrate it and have it work with all of the other parts of your smart home.

What Makes the Emerson Sensi Such A Good Choice?

So now you know what a smart thermostat is and you’ve had a chance to look at two Emerson Sensi smart thermostat reviews, it’s time to discuss what sets the Sensi apart from other smart thermostats on the marketplace today.

Easy Setup – Let’s face it. One of the major hurdles for getting a smart thermostat is actually connecting the thing to your home. When you get a smart thermostat, some recommend that you get it professionally installed.

That is because there are a lot of wires that connect an HVAC unit to a thermostat. Without knowing the difference between the RH and the W2 wire, you can cross-connections. And making an error in connecting a wire can be a costly mistake.

Not so with the Emerson Sensi smart thermostat. When you take the unit out of the box, the installation guide tells you to download the proprietary Sensi app. It is available on both the Android and the iOS stores. After you create an account, you select the option to “Install new thermostat on the wall and connect to Wi-Fi.”

Once you select this, you then will be prompted to enter the wires that your old thermostat has. The app will then walk you through connecting them to your new Sensi thermostat. There are 16 steps to fully connecting your thermostat, but once you’re done, you’ll be amazed that it was that easy.

And if you have any problems while doing the installation, you can call Emerson’s excellent technical support 7 days a week as late as 8 p.m. on weekdays CST and 6 p.m. CST on weekends.

Different Modes For Different Needs – One nice thing about the Emerson Sensi smart thermostat line is the fan mode. If you want to just have air circulating, then you can turn the fan on and leave it on. You don’t have to mess with any other settings; you can just have the fan blowing and circulating air. This is especially nice if you have allergies and it’s a particularly bad day for pollen or ragweed or whatever your particular allergen is. You likely have a good quality filter in your HVAC system to filter out allergens, possibly a MERV-12 or higher filter. Running the fan lets you perform as many air changes as it takes so you aren’t sneezing and suffering from runny eyes or a drippy nose.

Another mode that the Sensi offers is the temperature hold. There are times when you don’t want the temperature to change according to your normal schedule. With this mode, you temporarily disable your schedule and then adjust the temperature. Now, no matter what, the HVAC system will keep your home at that set temperature.

You can also set a temporary hold if you like without worry. This enables you to set the temperature to something outside of your normal schedule and forget about it. When the next event comes along, the thermostat will then follow whatever program you have set for it. For example, let’s say you have a party, and with all the people in your home, you want the temperature to stay at 70 degrees Fahrenheit. With either of these hold options, you can worry about your guests without worrying about the temperature in your home.

Best Emerson Sensi Smart Thermostat Review Ease of Schedule Setting– It’s no good having a programmable thermostat if the darn thing is too complicated to program or use. Thankfully, that’s not the case with the Sensi line of smart thermostats. You can use the app to easily set a schedule, or you can do it manually on the thermostat itself. If you’re going to set the schedule on the thermostat, you do need to disable its Wi-Fi first. Then you can select if you want it to run the heat or the air conditioning. Of course, if you live in the northern hemisphere, you want to cool during the summer and heat during winter.

After that, it’s just a matter of setting the times of the events and then what temperatures you want to be set after those events take place.

Aesthetics and You – Sometimes when you are looking for a smart thermostat, you want a unit that is going to mesh in with the rest of your stuff. And sometimes you want something that actually looks like you remember a thermostat looking like. There’s nothing wrong with a shiny black hockey puck stuck to your wall, but that aesthetic isn’t for everyone.

Emerson’s Sensi line is white with a classic form factor. Nobody is going to mistake a Sensi smart thermostat for anything but what it is; a thermostat that keeps your house at the right temperature and saves you money at the same time.

Depending on the model of Sensi that you get, you can get a white matte finish housing or even a black matte finish. Whatever it takes for your Emerson Sensi smart thermostat to look its best on your walls.

Compatibility – You need a smart thermostat that works with whatever HVAC system you have, and you need it to just plain work. That’s where the Sensi shines. It can handle heat pumps that have up to 4 stages of heating and 2 stages of cooling. It can work with dual fuel and geothermal equipment. It can work with gas, electric and oil HVAC systems as well.

Okay, there are some things that Sensi doesn’t work well with. Those are high voltage baseboard heating systems. But that’s pretty much it. Sensi will even control millivolt (mV) systems like fireplaces and wood-burning stoves. You just need a transformer that steps up the voltage to 24 volts and you’re good to go. Your Sensi is now up and running and working even better than you thought it would.

Best Emerson Sensi Smart Thermostat Review Reports and Information at Your Fingertips – You might be the type of person who likes to sit back and just let things work. If you are, that’s great; the Sensi line of smart thermostats will work like a dream, saving you money on your heating and cooling bill. But if you’re the type of person who craves more information, and the more, the better, then Sensi has you covered in spades.

You can get usage reports emailed directly to you each month. The report will contain an overview of system runtime, the average humidity, and any important reminders, such as changing your filters. Best of all, if you have more than one Sensi thermostat, you get a report on each, with the thermostat’s name printed at the top of the report.

The report breaks down the number of hours used in the number of cooling hours and the number of heating hours, so you’re always able to keep track of each. It’s all the information you need to keep track of your heating and cooling, while not being overwhelming.

Run Multiple Thermostats with Ease – If you have more than one Sensi in your home or business, you need a way to keep track of them that’s more intuitive than just from your phone. Emerson offers an app that groups all of your Sensi smart thermostats in one convenient location, giving you full drag and drop functionality that gives you full control over the climate at your home or business.

You can do batch controls and scheduling amongst all of the thermostats, which is going to save you money and minimize the amount of overhead and energy wasted. And if you really want to control your thermostats, you can lock out each individual unit so that no one can change the settings there. Instead, you have complete control. You can even set limits so that users can adjust the temperature within a range that you prescribe. No more will you see one building with a high energy usage for heating and cooling because the workers set the thermostat to 55 degrees.

Not Just For Residential Applications – You might think that a smart thermostat is only for the home. But it is not. A smart thermostat is an intelligent decision for anyone, whether they own a home, run a business or manage 20 buildings. The Sensi smart thermostat offers comprehensive solutions for churches, schools, and other commercial applications.

Schools no longer have to worry about teachers and maintenance staff having to remember to set the thermostats at set temperatures when they leave. The smart thermostats take care of that for them. With the ability to control multiple units and multiple zones, the Sensi smart thermostats allow property managers and facility directors the ability to take full control over their heating and cooling energy use and the costs.


There are a number of things that make the Emerson Sensi a smart choice for the discerning consumer. When you review all of the features available to you when you own a Sensi combined with the pleasing aesthetics, it’s easy to see that the Sensi line of smart thermostats is a great choice. Hopefully, this guide has helped you choose which Sensi thermostat is right for your needs and your lifestyle.
