The term “thermostat” is widely known as the device that connects to a heating or cooling system in order to monitor and adjust its functioning depending on the temperature you set. These are a more complex type that allows for remote control via an internet connection so that you can have access to them even if you are not at home.
Moreover, smart models have the ability to adjust their operating according to aspects like your usual settings or ambient factors. If the subject arouses your interest, keep reading to learn more about this innovative concept.
Smart vs. Classic – Differences
Their internet connectivity enables them to connect to your phone and make all the changes remotely. You can even download apps that monitor and keep tabs on the average temperatures and let you customize the environment according to the season. Moreover, they use multiple sensors that not only monitor air quality but also allow them to adjust their functioning on their own in order to reach your favorite room temperature.
A good model can even sense your presence in the room and adjust its operating or memorize your settings and turn on or off depending on your schedule. The intelligent thermostats are a component of Home Automation that makes your house smarter and easier to control from a distance. All the devices that are part of the Automation concept are internet-compatible and can be synced so that they can be monitored and accessed using a smartphone, tablet, or computer.
They can be linked to several systems in your house, such as air conditioners, heat pumps, HVAC, hot water tanks, and whole-house heating and cooling systems. This way, you can have full control over them using only your phone, which is much more comfortable than having to access each system separately.
Nonetheless, these devices are more convenient and will provide a long-term efficiency but for you to be convinced they are worth their price, you need to find out which are the benefits they bring. Let’s discover the reasons
why you should go past the high price and the effort of replacing your old thermostat with a high-end model.

Therefore, make sure you go for a model that is easy to install, comes with all the necessary components and includes the user’s manual so you will not get stuck mid-installation.
- Ease of Use
An intuitive control panel and clear specifications are also helpful because they will guarantee you will not have troubles setting it up and using it. Check the model you laid eyes on to see if it is user-friendly and if it is available in your language. A large display with night lights and clearly drawn pictograms will be easier to read even from a distance or in the dark.
- Multiple Systems Compatibility
Another important specification you need to check is its compatibility with various systems in your house, such as AC or heat pumps. This will enable you to use it for multiple tasks without having to replace your existing system.
- Many Parameters Displayed
If you really want to enjoy full convenience, get a model that displays not only the room temperature but also the humidity, outdoor weather, or the date and time. Most of the top products show multiple data on the screen so that you check it, you can learn many parameters.
- Voice Control
This is a great feature most high-end models offer via another device called Alexa Amazon which allows you to give commands using your voice. This way, even if you do not have your phone, you can still set it by simply talking to it.
We noticed that this industry has some leading manufacturers which manage to constantly improve their products and bring home automation closer to you. While there are dozens of models on the market, only a few include everything you need for your home and these models are
designed by the following top rated brands.
- Nest
This is, by far, the finest brand that has gained the trust of customers by only offering exquisite products at the best prices. They are leaders in the security camera section and they also provide a series of devices that contribute to making your home more comfortable. They focus on turning every home into a better place and they manage to do so by only resorting to the most innovative technologies.

What You Should Look Into
After we determined the main characteristics, we perused the market to find
the most reliable products that contain a majority of the main features. We sorted them and ranked them according to their specifications and you can see below what stood behind our ratings.
- A Reliable Brand
From experience, we know that a reputable manufacturer is more likely to deliver top-notch products designed to the highest standards and using the most qualitative components. This was also true with the models we reviewed so we eventually picked products from popular brands like Nest, Honeywell, and Ecobee. We were impressed with the attention to details and the advanced technologies used in designing their products.
- Internet Connectivity
It could not be smart unless it was able to connect to the internet. The ones we chose were highly accurate in detecting Wi-Fi connections and immediately connect to them. The signal was strong and they were easy to control via smart devices even from long distances.
- Dedicated App
If you want to be able to keep tabs on your energy consumption, check the status of your heating system, or memorize seasonal or weekly settings, you will have to get an app that will sync all the data received by it. As such, a dedicated app is mandatory to make it not only easier to use but also more versatile.
- Number of Sensors
Regular thermostats only measure indoor temperature because they were only able to detect the air temp in a room. Smart versions rely on a plethora of sensors that can also monitor air humidity or send data on the outdoor weather. The best ones, like the Nest, can even sense your presence in the room and automatically turn on whenever you step in.
- Distance Control
Thanks to home automation, you can access, check, and set it even if you are at the office so you can save energy or prepare your home for when you will arrive. This is possible due to the remote control setting of these ingenious gadgets that bring comfort to a whole new level.
- Programmable Feature
The best models come with the option of being programmed to work during a certain interval and they can even memorize the settings and repeat them when needed. They memorize your schedule and create a pattern and you can even set different temperatures for different rooms. The smartness goes far beyond regular and you can even insert users or lock it for children.

These do much more than that and allow you to have full control of the air and water heating and cooling systems in your house.
