Best smart thermostats to keep your home cool this summer
Smart thermostats add convenience to your smart home: They allow you to control your home’s temperature by voice command. You can also control temperature remotely, so your home can be cooled just before you arrive home from summer vacation.
An even better reason to use a smart thermostat? Savings on your energy bills. Some have sensors that detect when you are away from home and adjust temperatures accordingly. They also offer plenty of data on your energy usage, so you can track just how much you’ve used your air conditioning this summer (or heat in the coming winter).
Google Nest Learning Thermostat
Like other smart thermostats, the Google Nest Learning Thermostat is an energy saver. When you’re out of the house, the thermostat turns itself down. And like its competitors, the Google Nest Learning Thermostat can be controlled remotely via an app.
Unlike some other smart thermostats, and even some other Google Nest devices, the Google Nest Learning Thermostat doesn’t just process the numbers you feed it daily; it uses them to adjust the temperature to your preferences. If you allow it, the thermostat will, say, warm the house to 69 degrees by 7 a.m. because it knows you like the house that way when you wake up.
The battery-powered Google Nest Learning Thermostat is said to be compatible with 95% of home heating and air-conditioning systems. Rated 4.5 stars.

Google Nest Thermostat

Like the Google Nest Learning Thermostat, the Google Nest smart thermostat looks out for your energy bill, and turns itself down when you’re away. And like its sibling device, you can control it remotely via your phone or device of your choice. (And, yup, it works with either iOS or Android phones.) Google says that installation will take you about 30 minutes or less; the same amount of time it says you’d need to set up the Google Nest Learning Thermostat. Rated 4.3 stars.

The Amazon smart thermostat is the No. 1-selling programmable thermostat on Amazon. List prices start at $60 for a smart thermostat without a C-wire (or, common-wire) power adapter kit.

As you might’ve guessed, the Amazon Smart Thermostat works with Alexa, but it’s not a two-way communication device. If you want to tell it that you’re leaving the house, and that you want it to adjust the air conditioning accordingly, then you need to give that instruction through the Alexa app or via an Alexa-enabled device. Rated 4.2 stars.
Benefits of smart thermostats
Not sure if a smart thermostat is right for you? Explore the benefits of smart thermostats below to learn more about why you may want to install one in your home.
Lower energy bills
A new smart thermostat could end up saving you quite a bit of money on electricity or gas — enough to pay back the thermostat many times over. A summary of studies on Nest thermostat usage show “savings equal to about 10% to 12% of heating usage and electric savings equal to about 15% of cooling usage in homes with central air conditioning.”
Voice and mobile app control
The best smart thermostats will also work with your existing smart home devices including smart speakers along. They also often have compatible mobile apps that let you control the temperature at home from anywhere.
Forgot to adjust the thermostat before you left the house? No problem, change the settings from anywhere so that you’re not wasting energy on heating or cooling the house when nobody’s home. You can even log back in later to adjust the temperature to your liking before you arrive home again. Want to turn up the heat without getting out of the covers? Ask Alexa or Google Assistant. Hands-free temperature adjustments are a major perk of having a smart thermostat.
Temperature automation
Love to some extra heat when you wake up in the morning or need the room cool to fall asleep at night? Some smart thermostats can learn your daily routine and temperature preferences to automatically adjust your home’s temperature to your preferences throughout the day.
