Add to that the extended compatibility with fans, HVAC systems, hot water systems, and more, and you have one of the most versatile thermostats enabled for Home Automation.

It’s biggest drawbacks are the facts that it only monitors and shows temperature and that the battery only lasts for 9,000 hours, which is actually very annoying.

PROS	CONS

VERDICT

6. Honeywell RTH6580WF

First off, know that, as opposed to other thermostats on our list, this one is actually quite convenient in terms of pricing. Thus, you are more likely to afford it.

PROS	CONS
Allows you to program it as you like for every day of the week	Not the easiest to set up – some had issue with the WiFi setup
Smart Response feature enables it to learn your heating/cooling cycles
Cheap price makes it quite accessible
Works with Alexa, so voice control is possible with this separate purchase
VERDICT

Best of all, it comes at a reasonable price which makes it quite accessible.

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.

Differences between Smart and Normal Thermostats

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. The thermostats 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.

Why Choose Smart over Regular Thermostats?

Nonetheless, these smart 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.

• Convenience

Needless to say, this is one of the reasons why they are better than regular thermostats. The fact that you can connect it to multiple systems and that you can access them via the internet is of great help especially if you travel a lot and you need to keep tabs on the energy consumption of your cooling and heating systems. You can also check the indoor humidity level, the outdoor temperature, and customize your setting so your home will always welcome you with the perfect ambiance.

• Efficiency

They are more efficient because they provide a wide range of information and they can be synced with many systems. Not only the air will be brought to the right temperature but will be done even without you interfering with their functioning. The smart technologies they use allow them to operate mostly on their own and adjust their running schedule according to your own schedule.

• Money saving

The fact that the thermostat will turn on and off whenever it senses it’s right will also lead to reduced electricity usage. Not wasting energy for heating empty rooms and turning off at night or when you are at work means fewer expenses and a 23% lower annual electricity bill. Despite the fact the purchase price is significantly higher than a normal thermostat, the investment will be absorbed in a couple of years.

• Versatility

While other types of thermostats can only be connected to one system in your home, this one can handle almost any system you use for heating or cooling the air and the water you use. The wide compatibility makes it suitable for use with whole house air conditioners, heat pumps, ventilation systems, and water heaters. Some can even be linked to air dehumidifiers in order to maintain the proper air moisture level. This way, you will only be using one thermostat for the entire house.

Tips for Choosing the Best

When it comes to purchasing devices you are not familiar with, it’s not easy to pick the one that provides the best price-quality ratio and that will turn out to be the most effective. As such, it is useful to know which are the details that really matter so you will know you have made the right choice.

• Ease in Installation

Since this is an innovative device, the last thing you will want is to get tangled in wires and deal with a cumbersome installation. 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 smart 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 the thermostat by simply talking to it.

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

A thermostat 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 the thermostat. 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 the thermostat for children.
