Best SmartThings Compatible Thermostats


Despite the fact that heating and cooling setups vary a lot, one thing is certain: you need a good thermostat to control your HVAC system properly.

While any thermostat can do the job, you wouldn’t want something that will fail you in the middle of the coldest month. If you own a SmartThings device (check out the latest device), then having the best SmartThings-compatible thermostat should be your priority.

I’ve owned a couple of thermostats and it goes without saying that some have left me far from impressed. After acquiring a SmartThings device, which my older thermostat wasn’t compatible with, I decided to do extensive research into SmartThings compatible thermostats and came up with the list below.

I hope my findings will help you to select the best thermostat that is within your price range.

Things to Consider When Choosing a SmartThings-Compatible Thermostat

There are many thermostats available, but some are better than others due to several reasons.

C-Wire Requirement

If your heating and cooling system has a C-Wire, then you have a much easier task to choose a smart thermostat that provides an option for a C-Wire connection. Besides, you wouldn’t have to worry about buying batteries for your thermostat. On the other hand, if you don’t have a C-Wire, consider using a C-Wire adapter. While you can use an R-Wire in some cases, it isn’t recommended.

The Ease of Installation

Most thermostats nowadays are easy to install and you can do a DIY within a few minutes. However, there are those that require expert help, which means you’ll have to spend more. Get a thermostat that is not only easy to install but comes with a manual and troubleshooting guide to make things easier.

Ease of Learning and Control

A good smart thermostat should have one of the following three main types of smart thermostat technologies: learning algorithms, geo-fencing and motion sensors. These features make it possible to program and operate your thermostat remotely.

  1. Geo-fencing: Allows the thermostat to sense when you enter and leave the set home perimeter and adjusts temperatures accordingly. This feature can help reduce energy costs.
  2. Remote Access: With remote access, you can control your thermostat right from your smartphone or computer from wherever you are in the world. No more expensive energy bills just because you forgot to turn your heater down when leaving the house.
  3. Learning Algorithms: Self-learning capabilities that enable it to create automatic settings based on your behavioral patterns. Not only does this feature eliminate the waiting period for a thermostat to reach desired temperatures, but it can also help in saving energy.


Determine whether your thermostat supports other compatible devices and systems such as multi-stage or heat pump systems. Most importantly, it should be compatible with Samsung SmartThings device. It should have an integration system, an app, and commands that link it to other systems.

The User Interface

It should be easy to set up and operate. The smart thermostat should deliver important information at a glance and easily adapt to your specific individual behavior pattern.
