Google Nest

Google Nest smart thermostats are part of the Google Nest family of Alexa-enabled smart home products. The range includes DIY security devices, such as the Google Nest Outdoor Cam, but is arguably best known for its thermostats. On Amazon, the Google Nest Learning Thermostat is the retail giant’s #2 best-selling programmable thermostat.

Like other smart thermostats, the Google Nest Learning Thermostat is an energy saver. When you are outside the house, the thermostat lowers itself. And like its competitors, the Google Nest Learning Thermostat can be controlled remotely via an app.

Unlike other smart thermostats, and even other Google Nest devices, the Google Nest Learning Thermostat doesn’t just process the numbers you feed it every day; he uses them to please you. If you let it, the thermostat will warm the house to, say, 69 degrees by 7 am 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 cooling systems.

You can get the Google Nest Learning Thermostat on sale at Amazon for $199, which is a 20% markdown from the list price. The thermostat is available in a variety of colors including brass and stainless steel.

The Google Nest Thermostat Standard is the third best-selling programmable thermostat on Amazon. We found the device for as little as $115 on Amazon. (Prices vary depending on the color of the model.)

Like the Google Nest Learning Thermostat, the Google Nest monitors your energy bill and lowers itself when you’re away. And like its sibling device, you can control it remotely via your phone or the device of your choice. (And, yes, it works with iOS or Android phones.) Google says it’ll take you about 30 minutes or less to install; the same time it says you would need to set up the Google Nest Learning Thermostat.

Amazon smart thermometer

Amazon entered the smart thermostat market with a bang in 2021 with the launch of the Amazon Smart Thermostat.

The Amazon Smart Thermostat is the #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. You may need a C-wire adapter to properly hook up your smart thermostat – or you may not, depending on your current thermostat. (It is best to check before you buy.) The thermostat with the C-wire power adapter is listed for $85. Both models are currently for sale on Amazon; the model without the Cord C is just $48.

(By the way, Google Nest devices don’t come with C wire requirements.)

As you might have guessed, the Amazon Smart Thermostat works with Alexa, but it’s not a two-way communication device. If you want to tell him that you are leaving the house and want him to adjust the air conditioning on dely, then you must give this instruction through the Alexa app or through an Alexa-enabled device.

Honeywell

Honeywell has long been a name in the home-tech space; its technology even helps power the Amazon smart thermostat. On Amazon, one of its smart thermostats is the retail giant’s fifth-biggest seller among programmable thermostats.

Honeywell RTH9600WF Smart Thermostat

The Honeywell RTH9600WF is a completely new entry; the smart thermostat debuted in March 2022. It has a color display screen (which can even show you today’s weather forecast), and it can be controlled via a variety of AI assistants, including including Alexa and Google Assistant. Please note, Honeywell says C-wire power adapter is Mandatory.

Prices for the Honeywell RTH9600WF vary depending on color and whether you’re buying it with a C-wire power adapter. On Amazon, the best deal we saw was for a gray model without the adapter; it’s on sale for $129.

Ecobee

Ecobee is another big name among smart thermostat buyers. On Amazon, three of its devices or bundles are among Amazon’s top 10 best-selling programmable thermostats. Chief among them is the top rated Ecobee3 Lite.
