If you want to own a smart thermostat without having to break the bank, the Connected Control BCC100 is right at your alley. This budget thermostat works with any 24-volt heating, ventilation, and conditioning (HVAC) systems which include conventional gas and oil. For the electric system, it has two cooling and two heating stages, while its heat pump system has two cooling and four heating stages.

This device can be connected via Wi-Fi to any Android or iOS phone using an app, thus giving you access to its controls from virtually anywhere. While this may be the case, the device comes with a basic pre-programmed schedule pre-set at a comfortable 70 degrees. Thus, this thermostat isn’t solely reliant on the app to be functional.

It also comes with a 5-inch touchscreen display where you can see the current temperature, mode, and schedule. You can set daily and weekly cooling and heating schedules with up to four schedules and eight temperature threshold per day. The thermostat also automatically turns on the system when the target threshold is reached and immediately sends an alert via your phone.

Unlike its rivals in this category, though, the Connected Control BCC100 does not have any sensors that should wake it up when someone approaches the unit. It also can’t be connected with other smart-home hubs like Wink or Smart Things, as well as digital assistants like Google Assistant or Amazon’s Alexa.

Dimensions: 5.2 x 3.1 x 1-inches
Screen Size: 5-inch full-color touchscreen; 854 x 480 pixels
Sensors: Temperature
Connectivity: Wi-Fi
Zonal Control: None


  • Easy to install and configure
  • Large, very readable screen
  • Compatible with a lot of HVAC systems
  • Can work autonomously without the App


  • Does not have a motion sensor
  • Lacks smart-home hub connectivity


2. Ecobee 4 Smart Thermostat


When it comes to being “smart,” the Ecobee 4 is one of the most intelligent thermostats today since it comes with its own built-in Alexa support. Hence, aside from regulating your home’s temperature, this device can also order you pizza and over a thousand other things out of the Amazon assistant’s skill library.

The bread and butter of the Ecobee4, though, are its remote sensors. Its battery-operated satellites allow you to measure the temperature in any part of your home. This allows you to fix any type of cooling and heating issues such as averaging the warmth all throughout the different rooms of your home. It also has a “follow me” feature, which can adjust your residence’s temperature based on where the user goes.

Another nifty feature of this thermostat is its clear 3.5-inch LCD touchscreen with an intuitive user interface that allows you to set a personalized schedule quickly. Using the unit, the app or Ecobee’s website you can also you can also program a baseline comfort settings so the temperature won’t jack up especially during early mornings.

Because of its premium price and pretty advanced features, the Ecobee 4 is always compared with the gorgeous, iPod-like Nest Learning Thermostat. While the former may lose aesthetically, it won’t lose to functionality. However, unlike the Nest thermostat, Ecobee 4 doesn’t have a learning feature and relies solely on the user’s setting preference.

Dimensions: 4 x 1 x 4-inches
Screen Size: 3.5-inch full-color LCD  touchscreen; 320 x 480 resolution
Sensors: Temperature, proximity, ambient light, humidity
Connectivity: Wi-Fi, Bluetooth
Zonal Control: none


  • Works perfectly with other Alexa devices
  • Remote sensors enhance the accuracy
  • Schedules and geo-fencing temperature settings
  • User-friendly app and interface


  • A bit more expensive
  • Unchangeable “Alexa” wake word


3. Emerson Sensi Touch

Traditional thermostats will always have its loyal customers and if you just happen to be one of them you can never go wrong with the Sensi Touch. This mid-range thermostat has a large 4.3-inch touchscreen display with 272 x 480 resolution which you can also customize. The device is also easy to install and comes with the usual rear plate that you screw to the wall and the main body. During installation, however, you will need a C-wire.

You can also set a schedule when your home’s temperature should change with 15-minute increments. In case you don’t want to set a daily schedule, you can easily rely on the device’s geofencing feature. Depending on your phone’s location it can use different temperature preferences. Being within 3 miles from your home, for example, will make it use the usual “home” setting. However, when you remove yourself from this range, the device will use the energy saving setting instead.

After installing the device to the wall and you turned it on you can learn more about the setup process through the downloadable Sensi app. You can also use this app to set the schedule and create notifications and alerts. If you are an iOS user the app also allows you to connect to other Homekit-compatible smart devices.

However, this Emerson thermostat also has a few disadvantages that you should note. The most noticeable is that you can only set or adjust the schedules using the app and not directly with the main unit itself. The geofencing feature is also not customizable plus you can’t control when the device switches to sleep mode.

Dimensions: 5.6 x 3.4 x 1.2-inches
Screen Size: 4.3-inch touchscreen; 272 x 480 resolution
Sensors: Temperature, proximity, humidity
Connectivity: Wi-Fi, Bluetooth
Zonal Control: Yes


  • Has geofencing feature
  • Large touchscreen display
  • Customizable user interface
  • Auto detects humidity and temperature extremes


  • Unpreventable sleep mode
  • Doesn’t display outdoor temperature

Hive is owned by British leading energy provider Centrica and most of their products have only been available in the US beginning 2017. However, that doesn’t erase the fact that the brand is one of the most experienced manufacturers in home heating solutions. The beautifully designed Active Heating 2 is their entry in the premium smart thermostats category.

At the center of its 3.5-inch TFT display is a mechanical dial which can be moved clockwise or counter-clockwise to control the temperature. At the bottom are three clickable buttons- the left being a back button, the center brings up extra settings such as a child lock and the right being the confirm key. There is also a downloadable Hive app for better convenience. The best bit about this device though is it can provide multizone comfort with active heating.

Much like its rivals, this smart thermostat has also been integrated with Amazon’s Alexa. Thus, you can control your heating preferences with your voice. The true potential of the Active Heating 2 comes alive if you paired it with other smart devices from Hive such as their light bulbs and cameras which also have smart functions. However, the challenging part of owning this system is you may need to hire a professional installer since the installation process is quite complicated.

Another downside of this thermostat though is the active heating feature isn’t supported by Apple’s Homekit. Thus, if you have already invested in smart home devices from Apple you may think twice before buying this one. Overall, this thermostat offers a lot of value in terms of its functionality and ability to control multiple zones.

Dimensions: 4 x 4 x 1.9-inches
Screen Size: 3.5-inch color TFT display; 320 x 480 resolution
Sensors: Temperature
Connectivity: Zigbee HA 2.0
Zonal Control: Multi Zone with Active Heating


  • Easy to use
  • Intuitive user interface
  • A great looking thermostat system
  • Seamless Alexa integration


  • Requires professional help to install
  • Doesn’t have motion sensors

If you’re the kind of homeowner who prefers simplicity in all things, then the EvoHome is just right about your alley. This thermostat has a durable no-frills design with an exterior made of plain white plastic. The package or kit contains a terminal and its dock but you will also have to purchase a  TRV valve for each radiator in your home that needs to be controlled.

The best bit about this thermostat is its ability to control even the most complicated heating system out there. It’s compatible with almost any heating system including underfloor heating. This feature is a godsend for a home whose rooms need to have different temperature settings and varying heating schedules.

When setting up the EvoHome kit we recommend that you seek the assistance of professional installers to ensure everything will work perfectly. Getting the preferred temperature in each room can be quite a daunting task especially at the beginning as it involves a lot of trial and error. However, once you get it right customizing the schedule is simply a breeze. There is also an economy mode which changes all the heating down to just 15 degrees. The corresponding app is also easy to use and has access to all its features and controls.

Much like other systems, there are a few flaws in this thermostat, too. The screen is always on, and its “idle screen” is either a traditional clock face or digital display. While it can work with Alexa’s voice assist, the commands you can give are pretty limited compared to its competitors. Overall, if you really need a multi zone comfort control and does not mind the aesthetics of the device, then the EvoHome is a great choice.

Dimensions: 5.5 x 4 x 0.8-inches
Screen Size: 5-inch color LCD; 480 x 272 resolution
Sensors: Temperature
Connectivity: Wi-Fi, Bluetooth
Zonal Control: Yes


  • Can also do underfloor heating
  • Has zonal control
  • User-friendly and easy to operate
  • Durable design


  • Unimpressive design
  • Lacks additional features of its rivals

If you’re looking for an affordable alternative to premium smart thermostats, then the GEO-WH won’t leave you disappointed. While it does not have the elegant screens and sleek exterior of more expensive temperature control devices, it has a number of useful functions. This thing also has multiple power options such as batteries, a C-wire system power, and a micro-USB connection.

Despite being almost half the price of its premium rivals, this thermostat also works in conjunction with an Alexa device. As such, you can control the room’s temperature by your voice. It also comes with an Android or iOS app which makes it easier for you to manage its schedule. Moreover, this device also has a geofencing option with “away and back” settings and even allows Zonal Control.

Another exceptional feature of this thermostat is you can mount it to have either horizontal or vertical orientation. It also possesses an air filter monitor and is compatible with a lot of heating system. It’s also easy to install and set up even if it’s the first time you are digitalizing your home. Finally, the device also has a 3-year warranty.

But then again, you can say that this thermostat is not for the picky homeowner. The digital screen is unappealing plus the display is hard to read without the backlight. It also has some trouble getting a decent Wi-Fi signal, especially if it’s too far away from the router or has a few walls and obstacles in the way.

Dimensions: 6.5 x 2.8 x 6-inches
Screen Size: 3-inch digital screen
Sensors: Temperature, proximity
Connectivity: Wi-Fi, Bluetooth
Zonal Control: Yes


  • Affordable price
  • Can be integrated with Alexa
  • Has zonal control
  • Comes with geofencing feature


  • Black and white display
  • Finicky temperature readings

Bar none, the Nest Learning Thermostat is considered as the most intelligent thermostat device in the market today. Functionality wise, there are only a few smart products that can compare with it. It also has a very appealing iPod bezel-like design and a vividly clear touchscreen display with 480 x 480 resolution.

What separates this smart thermostat from the rest though is the sheer number of sensors that this thing has from proximity to field activity and more. Through its multiple sensors, the device learns most of your habits and schedules such as at what time you are at home the most and even the current season or climate. Using the data it has gathered, it then adapts to your habits and chooses the most comfortable or energy saving setting for your home.

The app is also quite useful in complementing the functions of the control unit. It also alters the heating when you don’t need it, such as in the case that you aren’t at your house. The motion sensors scan the area to check whether the residents of the house or perhaps some guests are inside the house or not. Finally, the metallic finish on the clock makes it a great décor to any part of your home.

On the flipside, you may find that the thermostat may overshoot the temperature adjustment by a bit since the program’s algorithm that learns your habit isn’t perfected yet. Nest has recently begun expanding their product lines, hence, for now, the Learning Thermostat is still a system on its own.

Dimensions: 3.3 x 1.2-inch
Screen Size: 3-inch color LCD; 480 x 480 resolution
Sensors: Temperature, proximity, indoor humidity, ambient light, far-field and near-field activity
Connectivity: Wi-Fi, Bluetooth, Wireless Interconnect
Zonal Control: No


  • Very smart and learns your heating patterns
  • Beautiful iPod-like design
  • Has motion sensors
  • Can learn your habits and automatically creates energy saving settings


  • Doesn’t have zonal control
  • Not compatible with Apple Homekit

You can think of the Tado Smart Thermostat as a hybrid thermostat that has almost everything. It has a sleek design, a zonal control, and even geofencing. However, balancing all these features together seems to be a tall order as there hasn’t really been a product to come up with such a cohesive system yet.  Regardless, this thermostat is still a great energy saving device which you definitely would like to have especially during the winter months.

One of the unique characteristics of its central thermostat is the combination of physical and touchscreen controls laid out in its nondescript white square design. It has a physical button which serves as a touchpad that lowers and raises the temperature. The individual radiator valves, on the other hand, are not as complicated but offer the same white text display.

Tado also works well with almost every major ecosystem out there such as Google Assistant, IFTTT and of course Alexa. Hence, you can use your voice to control your heating system and even pair all your heating mechanisms to other smart home devices. Furthermore, you can also integrate it with Apple’s Homekit. Setting up the schedules is also as easy as that of other premium thermostats in the list.

Despite all these eloquent features, Tado did not add any kind of motion-sensing sensors which could have made it more convenient just like the Nest. It also doesn’t have self-learning capabilities; hence you have to plan your schedule carefully if you optimally want to save energy. Lastly, the user interface may take a while to get used to especially because of its unusual control center.

Dimensions: 4.1 x 4.1 x 0.7-inch
Screen Size: LED matrix
Sensors: Temperature, Ambient Light, Humidity
Connectivity: Tado Internet Bridge (Ethernet port)
Zonal Control: Yes


  • Sleek and thin design
  • Has zonal control
  • Plenty of sensors
  • Works well with major ecosystems


  • Finicky app
  • Unattractive LED matrix screen


Smart Thermostats Buying Guide

Today’s thermostats can optimize the efficiency of your HVAC system and help you save a hefty sum on your utility bills. The device also allows your digitized home network to follow schedules and even be controlled even if you are halfway across the world provided you have an Internet connection. Some of the best thermostats even have advanced features like forecasts, “learning” ability and even motion sensors.

With more companies investing in the digital home industry, you can expect that smart thermostats will also evolve and have more functions in the future. With so much innovation in this space, it can be quite confusing for a buyer which smart thermostat can offer the satisfaction they need. This is where this article comes in- to be your guide and reference.

Let us look into some things that you should think about before buying a smart thermostat:

1. Technology

Not all thermostats are created equal in terms of its technological features. You want to have one that can connect with networks such as Wi-Fi and Bluetooth for better management and easy notifications. It should also be compatible with some of the digital home major ecosystems like Alexa, Google Assistant and Apple Homekit.

2. Mobile Access

The main allure of smart thermostats is you can control those using apps on mobile devices. While most devices are compatible with both Android and iOs devices, there are a few that only have one of the two operating systems. Make sure your mobile device is compatible with the thermostat you are eyeing for.

3. Sensors

Several thermostats have more than just temperature sensors and even come with motion detection, proximity, humidity and a lot more. Sensors are also crucial for some thermostats to “learn” the user’s habit and automate it to the most effective settings.

4. Geofencing

Many thermostats also have geofencing features which turn off or change the temperature of the room or house depending on the proximity of the user. For example, if you connect the thermostat with your mobile phone and you step off 300-meters away from the control unit the device can shut itself down or lower its temperature.

A smart thermostat can do a lot of good for your home. Aside from keeping up with your heating schedule it also saves you a lot of money that goes into your power bill. It also doesn’t require a hefty sum to start digitizing your home with this device.
