Why buy a SmartThings-compatible thermostat?

Adding your thermostat to the Samsung SmartThings ecosystem enhances the monitoring and control capabilities of your HVAC system. Via the SmartThings hub, your thermostats link with various sensors and home devices that help them integrate better with your personal needs.

For example, if you have motion sensors on your entry door, you can tweak your smart network to start the thermostat when the sensors see you entering the home. 


Furthermore, instead of using extra wiring, these smart thermostats can access outdoor information like temperature, humidity and incoming weather via the hub, and improve performance while saving up on energy. 

SmartThings-compatible thermostats can also work with smart assistants such as Alexa, Siri, Hey Google, or Cortana, and provide voice control and remote access features. Moreover, depending on the product you choose, you can also enjoy features like voice commands, room temperature sensors, preference-based scheduling, etc.

Controlling the temperature of your house and monitoring its climate, even when you’re away, brings a host of possibilities – with one of the most important being responsible use of energy. 

Mobile App

Let's not forget the convenience that controlling your HVAC system via a mobile app offers. You'll get real-time notifications of your household temperature, be able to turn the cooling/heating on or off according to weather fluctuations, and have your home ready to receive you with the perfect climate. 

In short, connecting a smart thermostat with Samsung SmartThings is awesome! Now let's see what the best devices that you can do this with are.

The ecobee SmartThermostat gives new meaning to the word smart with features like the pause, home, and away modes and intelligent scheduling functions.

Smart Sensors

Additionally, the product comes equipped with a SmartSensor that you can place anywhere and use to control the temperature in your home. The SmartSensor can gauge a room's occupancy and help manage the temperature accordingly. You can also control the added wireless device from your smart home assistant or directly from the app.

In addition to its Samsung SmartThings compatibility,  the ecobee SmartThermostat is also designed to work with Amazon Alexa and Google Assistant. So, you can manage the HVAC system in your home with voice commands. Plus, there's also Spotify compatibility which allows you to stream music or podcasts.

The latest ‘pause' feature can detect whether a window or door has been left open. If the SmartThermostat notices there's an outlet affecting your room temperature for more than five minutes, you'll receive an instant notification, while the thermostat takes care of the problem for you by turning off your air conditioning.

Top Features
  • Learns your consumption schedules and programs itself to save energy.
  • Offers voice command control via Alexa and Google Assistant.
  • Easily installed in 30 minutes or less.

Google Nest is arguably one of the most popular, commercially available smart thermostats. The thermostat has a sleek, modern, and minimalistic design that's beautifully offset by the large LCD. 


While the third generation of Nest Learning Thermostats doesn't differ too much from the previous versions, they're more compact. They offer a few new features, such as the (separately purchasable) sensor that displays the indoor climate, weather forecasts and seamlessly integrates with Google Assistant and Alexa. 

That means you can opt to buy several sensors, along with one Nest Thermostat to help your monitor and control the climate of your entire household. 

Intelligent Scheduling

Aside from that, the Nest Learning Thermostat is armed with most, if not all, features expected in modern smart thermostats, such as intelligent scheduling (that helps the thermostat pick up your HVAC pattern and adapt usage accordingly). There is a home/away feature to help you control your home temperature remotely. 

Nest Thermostats offer a little bit more in terms of remote control capabilities because you (or your family members) can follow and set temperatures from your phones, laptops, or tablets. 

Energy History

The energy history feature (accessible via the phone app or quick view on the thermostat's LCD) helps monitor your energy usage. There's also a handy maintenance feature that keeps an eye on your HVAC system for any concerns and can send out instant alerts if something needs your attention.

What I liked
  • Sleek and compact design.
  • Multiple helpful features like intelligent scheduling and maintenance alerts.
  • Larger LCD.
  • Good AI algorithms for learning energy consumption schedules and adapting to them.
  • Can work without a C-wire as well.
What I didn't like
  • Smart sensors have to be purchased separately.
  • Earlier versions had issues with taking power pulses from the HVAC system for charging, later models have the Power Connector. Although, that might require some basic rewiring.

The Sensi Smart Thermostat combines several handy features like voice control and usage reports and is competitively priced.

Top Features
  • The geofencing feature uses your location to adjust the thermostat.

The ST55 works well with the Apple HomeKit and Samsung SmartThing ecosystems, and it's also compatible with Amazon Alexa, Siri, and Google Assistant. The product is also relatively easy to install and program.

While it doesn't look as stylish as the Nest Learning Smart Thermostat, it still manages to pack quite a punch when it comes to features. The thermostat is ENERGY STAR certified in its limited budget and promises an overall savings of 23% on your HVAC costs. Then, there's the added convenience of hallmarks like geofencing, 7-day scheduling, and remote access and control through the mobile app. 

 The thermostat also provides you with regular usage reports that offer current stats and past HVAC runtimes to help you streamline your energy costs. There's also the smart alert feature that sends instant notifications relating to humidity and temperature levels.

  • Easy to install and program.
  • Offers remote access through voice assistants and the mobile app.
  • Has multiple features including geofencing, weather updates, keypad lockout, etc.
  • Automatically switches between heating and cooling, and the mobile app changes color to reflect the current status.

The Verdict

While the Samsung Smartthings Hub already provides a lot of features and interconnectivity, integrating a smart thermostat with it can make your home’s climate a lot more responsive and efficient, catering to your changing needs while keeping your utility bills low.

Most modern thermostats offer SmartThings integration, but not all of them. Choosing the right product will depend on your HVAC system, budget, and what features you want.
