A smart thermostat will be a welcome addition to any home, and if you’re interested in getting one, why not go for the best in the market? The fourth-generation Google Nest Learning Thermostat, which has an original price of $280, is on sale from Walmart for a much more affordable price of $198. There’s no telling how much time is remaining before the $82 discount expires, so you need to hurry with your purchase if you want to take advantage of this fantastic offer.

Why you should buy the Google Nest Learning Thermostat (4th Gen)

The fourth-generation Google Nest Learning Thermostat headlines our list of the best smart thermostats, and it’s even featured in our roundup of the best smart home devices. The first thing that you’ll notice about it is the premium design with a screen that’s 60% larger than its predecessor. You can customize the display’s appearance to show information like time, weather forecast, or outdoor air quality, in addition to your home’s temperature, and with the second-generation Google Nest Temperature Sensor, those readings will always be accurate.

Of course, the Google Nest Learning Thermostat is more than just a flashy device. Its features as a smart thermostat include an onboard AI that tracks your habits to make a schedule that fits your home, compatibility with the Google Assistant to work with voice commands, and the ability to monitor your HVAC system to let you know if you need to call a professional for service. You’ll also be able to use the Google Home app to control the Google Nest Learning Thermostat from anywhere, though of course, you also have the option of using its touch controls.

The fourth-generation Google Nest Learning Thermostat already offers excellent value at its original price of $280, so it’s a steal at its lowered price of only $198 from Walmart. The savings of $82 will only be available for a limited time though, so you should hurry! After this purchase of the Google Nest Learning Thermostat, if you want to build out your smart home ecosystem further, you should check out all of the other Google Nest deals that we’ve collected, which include smart displays, security cameras, and video doorbells.

This wild new TV mount moves your screen without you touching it

TVs can already adjust their picture and sound without much help from you. Perlegear now wants the physical screen to adapt to you as well.

Indoors, Interior Design, Lamp

TVs have become incredibly smart over the years. They can automatically tweak picture quality, adjust sound for your room, and recommend what you should watch next. Yet once you bolt one to the wall, there’s one decidedly old-fashioned thing about it: it’s staying exactly where you put it.

Perlegear has an interesting solution at IFA 2026. The company is showing off the AX1 Smart Adaptive Mount, a motorized TV mount that detects where you’re watching from and automatically moves the television to a more comfortable height. It’s an idea that sounds a little excessive until you think about how many different ways we use TVs today. You might be sitting on the couch for a movie, standing up for a workout, playing a motion-controlled game, or have kids watching from the floor. The ideal screen position for one isn’t necessarily great for the others.

iRobot’s new Roomba concept uses a piggybacking sidekick to reach tight spaces

The Roomba Duo pairs a powerful floor washer with a smaller robot built to clean hard-to-reach spots.

Robot vacuums have long forced buyers to choose between cleaning power and clearance. Heavy-duty wet-dry models pack enough scrubbing force to tackle stubborn, sticky messes, but their bulky frames often can't squeeze under low furniture. Slim robot vacuums can glide beneath sofas and beds, but they typically lack the muscle to do much more than sweep up light dust. iRobot's new Roomba Duo concept, unveiled at IFA 2026 in Berlin, aims to solve this problem with an unconventional approach that involves deploying two specialized robots to work as a team.

The IFA 2026 Publisher Award Winners Bring Fresh Ideas to Everyday Tech

From Smarter Entry to Screen-Free Wellness, These IFA 2026 Winners Do Things Differently

IFA 2026 Publisher Awards

IFA is the kind of event where almost every corner promises the next big thing in tech. Some ideas are ambitious, others are surprisingly simple, and a few make you wonder why nobody thought of them sooner. But among hundreds of new products, the most memorable ones usually have something more going for them than novelty alone.

This year’s IFA Publisher Award winners are a good example. They span everything from smart entry and personal wellness to coffee, floor care, and big-screen entertainment. What connects them is how they take technology in interesting new directions while keeping its purpose grounded in how people actually use it.
