The Comprehensive Buying Guide for the Best Smart Thermostats of 2020

The Best Smart Thermostats of 2020

Smart thermostats, today, do much more than automating climate control for heating and cooling your home. We’ve reviewed these app-enabled smart thermostats that allow you to control your thermostat from the comfort of your couch or on the go. Additionally, most of these devices are integrated with Alexa and Google Assistant enabling hands-free control.


Even better, most of the smart thermostats have an additional sensor for motion and temperature that can automatically control your temperature and gives greater temperature control in other rooms.

Best Overall

Ecobee SmartThermostat

The Smart Thermostat, which is priced at $245, is the latest in the Canadian company’s line of smart thermostats. It came to the market just two years after the Ecobee4 hit store shelves. Simply looking at the Ecobee Smart Thermostat, it would appear that there’s very little difference between it and the previous model. However, the Smart Thermostat has a fully functioning built-in speaker with Alexa support and a few other upgrades compared to the Ecobee4.

Best Remote Sensor

Overall, the T9 is a great smart thermostat that’s easy to set up and use. I wish it were slightly more affordable — more like $150 — but its geofencing, Smart Room Sensor and general performance worked reliably for me throughout my testing. This device can also be added to a broader Honeywell Home security and automation system, making it a great option if you want to scale up your smart home.

Best Voice Control

The Ecobee SmartThermostat is the perfect thermostat for voice control whether you’re using Google Assistant, Amazon Alexa, or Siri. And best of all, the overall commands are very similar. To check the current temperature, for example, you wake the device with either Alexa or Google Assistant. Then, you say, “What’s the thermostat temperature?” You can view a full list of the Alexa and Google Assistant commands on the manufacturer’s website.

While the Learning Thermostat has a stainless steel, circular shell with different options, such as, copper, the Nest Thermostat E has a white circular shell that’s very soft to touch similar to the Nest Cam Indoor IQ. It also turns in both directions so that users can change the temperature without using the Nest app and scroll through the different features and options.
