March’s Best Smart Thermostat Deals Keep to Keep You Cozy or Cool

The weather these months can chill you to the bone, even though Spring officially starts this week. If you’re living in a polar vortex and heating bills are climbing, it’s time to let technology shoulder some of the burden. Picking up a smart thermostat lets you tap into AI to monitor and adjust your heating with money-saving results. It can do the work of keeping your house warm and toasty and your bills down.

These modern HVAC controllers can rapidly adapt to temperature changes, and let you set schedules to accommodate your day at home (or away). With many of these smart thermostats, you can adjust your home’s target climate from your phone or with your voice, as well as tap into features like service reminders and activity monitoring. They pay for themselves in no time, especially with the huge discounts we’ve found on well-reviewed units from a variety of top smart home brands. Here comes the deals.

Google Nest Smart Thermostat Deals

Google’s entry-level smart thermostat received an “Excellent” rating in our 2020 review, with praise going to its breezy installation and full toolset, including integration with Google and Amazon smart home systems. All of the basic features you need are here for a little over a hundred bucks, including robust scheduling and energy monitoring reports that also suggest ways to improve efficiency and note potential issues with your HVAC system. It doesn’t have the advanced AI-powered adaptability of more expensive models, but if you can live without those it’s a decent deal at $15 off.

For something a little more feature-rich, the most recent Google Nest Learning Thermostat has a little discount at Walmart right now. In our review, contributing editor John Delaney gave it an “Excellent” rating thanks to its “large display, pleasing aesthetics, and remote room sensing.” He also highlighted that the ability to spread out thermometers across multiple locations refined its operation and made it even more efficient. This model also added even more smart home system interoperability, including the popular Matter standard. Ambient light, temperature, humidity and motion sensors give you tons of variables to build heating routines around, and it also works with humidifier and dehumidifier add-ons to many systems.

Sensi Smart Thermostat Deals

Traditional home appliance manufacturers are also competing in the smart thermostat space, and Emerson’s Sensi line combines their deep experience with HVAC systems with current-day technology. We gave an “Excellent” rating to the Sensi Touch 2 in our review, with numerous nice features like a large, responsive color touch screen, support for Amazon Alexa, Google Assistant, and SmartThings, and comprehensive energy reports. If you’ve got a big space to heat, support for up to 15 independent room sensors gives you a ton of precise control. Best Buy has it on sale for 21% off.

This older Sensi smart thermostat is a reliable piece of tech that still performs well. In our 2021 review, our expert praised its complement of useful features, including geofencing to reduce the ambient temperature when you’re more than three miles from your home, lots of reports including usage and weather, and support for multiple home automation platforms. Although the monochrome LCD screen isn’t the slickest, it still delivers tons of useful information, and the unit supports voice control through Alexa and Google Assistant. Take 36% off right now at Amazon.

Meross Smart Thermostat Deal

There are a few lesser-known brands working in the smart home space, and Chinese company Meross is celebrating its tenth year in business in 2026. They’ve continually expanded their product lines, introducing their first smart thermostat in 2022. Using the Matter smart home protocol, this unit works with most major platforms, including Amazon Alexa, Google Assistant, Samsung SmartThings, and more. The companion app gives you robust reports and the ability to set schedules, and setup is simple and lightning-fast. Smart alerts for system health, filter life, and other metrics make sure you keep up on maintenance. And $65 is a nice price!
