The advancement in technology brings ease for human beings, and technology becomes affordable for most people with the count of time. The best example is smart home devices; the trend to convert homes into smart homes is growing year after year. Dozens of manufacturers are making smart devices that provide full control over home appliances and electronics through the internet and app. These intelligent devices can communicate with each other. Now it’s possible to control the whole home’s temperature from one thermostat. The best smart thermostat for multiple zones will be a need to automate your home’s temperature altogether. 

The best smart thermostat for multiple zones supports room sensors that you can place in your house’s different rooms and areas. A sensor can detect the occupancy and temperature then signal the thermostat to switch to the right mode. 

These sensors also help to tune your thermostat to an optimal level. Like on the app, you can see the temperature of different rooms through the sensors and amend your schedule accordingly. Only a few products support multizone management, while with others, you need to buy more thermostats. We reviewed some of the best options available and found under-listed three most reliable and technologically advanced.

Smart home thermostats are quite different from the traditional thermostats that people use for many decades. In the backend operations, these intelligent thermostats control the heating and cooling devices without any human intervention. In the front end, they are equipped with a digital display and connectivity as well as compatibility. The advanced connectivity makes it possible to connect the thermostat with the Wifi, and users can access the full configuration through an app and can set preferred format as well as get alerts and can generate reports.

While compatibility with other devices enables these thermostats to communicate with other smart devices, Wi-Fi connectivity and the ability to communicate with other devices and take instruction are real game-changing features that allow users to have preferred temperature perfectly and conveniently.

In this article, we reviewed some of the best options available in the market that can control the temperature of multiple zones. Before moving forward, let’s have a look at the benefits that one will get with the multi-zone thermostat:

  • Reduce the equipment cost – you need to buy a single thermostat, and additional room sensors are cheaper to buy.
  • Lower installation cost – the main unit’s installation is required only, which saves the installation cost.
  • Better control – on the single app, you will have all the data and control from where you can customize each area separately.
  • Easy to manage – you can set the preferred temperature of different zones, and occupancy detection makes it energy-saving.
  • Energy-saving – with multizone thermostats, it becomes possible to run the heating and colling devices only when needed and necessary.

What to consider while buying the smart thermostat for multiple zones?

Buying a smart thermostat to manage multiple zones is not easy to job because many claim this feature. But I hardly find few choices in the market that can connect to google assistant and Alexa and control different low voltage air conditioning and heating systems. As we know well, smart devices can interact with each other, and a good buy can communicate and provide full control over the different parts of your house to manage and monitor the temperature effectively. 

During our research, I learned that compatibility and integration is the biggest issue as well as advantage that one may get or face when managing multiple zones from a single thermostat.

For a technology lover, it will always be the most prominent parameter while buying. But if you look in more detail, you will have to take care of a few other parameters, which are:

Room Sensors

Smart sensors that can access the temperature and other parameters are essential to managing your house’s different areas. These sensors are designed to act as a relay that provides the necessary information to the main unite; they connect to the thermostat via Bluetooth technology.

Like most advanced sensors can detect the human presence, and when a person enters the room, it sends information to thermostats, which turn on the devices to maintain the temperature.

Along with temperature, these sensors also can detect the humidity level and many other things. 

For every single room or area, you need a separate sensor. Most of the market thermostats come without a sensor, and you need to buy sensors. When you are purchasing additional sensors, you must check their compatibility with the device.

Sensors that can communicate quickly are best to use because they will not slow down your application response, and the central thermostat unit can have full command over them.

Distance is another factor that comes into effect and needs to consider seriously. Some models are made to work up to 50 feet, while costly options can communicate effectively from 200 feet. I recommend looking for low consumption Bluetooth sensors because they are quick and can communicate effectively from afar.

Connectivity with Smart Home Devices

Smart thermostats made to manage multiple zones from a single place are complete devices that can work independently or connect with Wifi. But during our review, connectivity with other smart options like Amazon Echo, Google assistant, Homekit, etc. Bring real ease that every smart homeowner wants in his life.

Connectivity with other smart home devices has some significant advantages like you can control the device through voice command, and with just a mouth word, you can change the setting. 

It also makes it possible to get it on the phone and provides you with effective control through other apps. Moreover, this connectivity is always good to manage the smart home devices from place conveniently. 

Power Extender Kit

Some specific models only work with C-Wire; you can look into specifications and requirements to figure it out. I believe that it’s an option like you have already installed C-wire installed in your smart home, then there is no need for a power extender kit. You can install a smart multi-zone thermostat into your existing wires.

But if you don’t have C-wire installed, you may require a power extender kit that will make it possible to run the thermostat through ordinary home wiring. 

Some models genuinely work with the ordinary house wiring, but with most of the thermostat models, it is required; usually, it’s not included in the package.

Voice Recognition

It is the most discussed feature and the most important one because 70% of household users control their smart devices with voice commands. When you get Alexa or another similar system compatibility, that means you are moving over to voice command.

Above I already discussed integration; the voice recognition feature is also covered in that. Connectivity to other smart options Amazon Echo, Google assistant, Homekit also enables this fantastic feature.

We list the best available system which is compatible with most smart home solutions.

Touch Screen

A good quality touch screen not only provides necessary information but is also a primary way to control the smart multi-zone thermostat. Through its touch screen, you can adjust the temperature schedule and can perform other required operations. It’s necessary, especially when you are in view to use mobile for every task.

I figure out that every smart homeowner looks first at temperature when he gets into the home; it should allow you to control the HVAC devices with ease. 

I recommend looking for a touch screen display that is user-friendly and easy o understand and provides all the necessary information and allows to set a schedule with minimum touches. Most modern options are good to have control over the heating and cooling devices.


It’s not necessary to look for this feature because advancement in technology makes it possible to increase or decrease a room’s temperature in minimum time. Smart devices can learn your schedule and prepare the required temperature while following the program. But if you are too cautious and want a preferred temperature inside when getting home, then geofencing is the only solution.

The smart thermostat can access your location through geofencing and turn on the devices to maintain the temperature when you reach your home.

User Friendly App & Home Away Feature

Look for a user-friendly app that you can understand because it will allow you to connect with the system and quickly change the setting. A clean and straightforward interface application is also easy to understand and gives full control over the system. Our recommended systems come with user-friendly apps that are easy to use. You may download and check the app before buying a thermostat. 

We advise you to look for a schedule and try to make your own, and figure out either it’s easy for you or not. You also have to consider the room sensors’ app connectivity that how much responsive they and what information is accessible from them.

Home away feature turns off all the devices when you are not at home, lowering your energy cost.

GLAS Smart Thermostat by Johnson Controls is a trusted device from a manufacturer making similar products for many years and has vast experience. But the story of this product is the different majority of customers do not like it, and its general reaction in the market is not good. The reason is not its functionality but its features that humans use to control the system. Even there is a lot of bias about this product, but here are some features which makes it a suitable device like:

  • Air quality sensors are a big plus.
  • It’s relatively easy to install.
  • Equipped with a built-in battery.
  • Its interface is quite simple and easy to understand.
  • The ultra-bright screen gives a futuristic look.

There is nothing that can allow increasing the time. It needs improvement in security features, especially timeout in case of a power failure and no sensor support is really a drawback. Instead of the sensor, you need to add an individual thermostat.

Traditional thermostats were designed to regulate your house’s temperature from a single point, whereby these do not have any digital feature. But in the last decade, a lot of development happened, like first digital thermostats his the market and then smart thermostats rule market.

Now it’s time for multizone thermostats in which small sensors are placed in different zones of your house, which communicate with the main unite and signal the temperature change and share other data like occupancy, which is a most modern feature. Then the main unit decides about the mode.

There is a massive list of features and customization available with these smart multizone thermostats; everybody can configure them as per his need. But on the negative side, there are a few disadvantages of using multi-zone thermostats.

Disadvantages of Multizone Thermostate

Smart homeowners discuss different negative aspects as per their own wish and setting, but there are two main disadvantages that we found:

  • The very first one is the ability to use a heating and cooling system simultaneously like if you want o cool one and heat another one, then it’s not possible with a multi-zone thermostat, you are bound to use heating only or to cool only, and there are few which restricts to set one temperature only in the whole house. When you change the temperature in one room, the temperature of the whole house changed automatically.
  • Secondly, you will become more app-dependent. To see the temperature of other rooms and zones, you need to use your app when you are there, while the display will be available on where the main thermostat is installed. It really matters because if someone else is sitting there who is not familiar with your system, then he might feel discomfort. 


Yes, it does, because multizone management from a single place provides effective control and energy-saving plans which are a built-in feature of these thermostats works best and only turn on on the basis of occupancy.

Well if you already have some experience of hardware then you can do it yourself in a matter of minutes, even if you are new manuals elaborate on how to install with C-wire and without C-wire and even videos are available on the manufacturer's channels with step by step guide.

Yes, you can, it's not necessary to connect all of your heating and cooling devices with your thermostat you may connect either heating or cooling devices so you can comfortably use one system at time and thermostat work fine even with a single system.

They are a sophisticated piece of engineering and technology, the small device which needs fast communication and needs to connect multiple devices at the same time as well as fast processing and reporting. the combination of these all features cost a lot, as well as they, are made to integrate with the smart application and home assistant solutions which are costly too. all of these factors increase their cost. But once installed you will feel that the convenience it brings is a lot more than its price.

Their ability to work with the multistory building also depends on their range as these are devices that communicate with each other through Bluetooth. Every system has a different range most of them are made for the range of 50 feet while ............. can work up to 200 feet that are amazing range and also can work with multistory building.

Final Words

We list all of available options that support multizone cooling, for a new smart thermostat use it may take time to understand how multizone temperature setting and thermostat configuration works best. Its time taking to learn but once you get hands on it then all become easy for you. 

All of manufacturers are trust worthy and provide warranty as well as support that will keep your investment secure. So, choose any Best Smart Thermostat for Multiple Zones that fits best to your needs.
