The SwitchBot Hub 3 smart home controller is now available for purchase. The Matter-capable device is quite different than other smart home hubs we've tested, starting with its rotary knob that can adjust the target temperature on a smart thermostat, the brightness of smart lighting devices, or the volume level of a connected speaker. Another feature that makes the 120 controller so interesting is the USB-C cable that connects it to its power supply: The cable senses the ambient temperature and relative humidity in the room where the Hub 3 is installed. These readings are shown on the hub's display. We have a hands-on review of the all-new SwitchBot Ultra, which is also shipping today.

From game-changing text diffusion models and cutting-edge AR glasses to AI videos with sound and virtual clothing try-ons, there was plenty of amazing tech to see during Google's I/O keynote on Tuesday. The closest we got to a smart home shout-out was when a Google exec said that Gemini--the star of the show--is "coming to your watch, your car dashboard, even your TV." As Google puts its Google TV Streamer under the umbrella of smart home, we'll count that as a fleeting reference. Officially, Google has promised that Gemini is coming to Nest devices. Gemini on Nest speakers has been available on a public-preview basis for months now, and back in March, Google confirmed that a "new experience powered by Gemini" is coming to smart speakers and displays.

Got your eye on a new laptop, smartphone, TV, or gaming console? Be prepared to shell out more money if and when you decide to buy it. A new report released this week by the Consumer Technology Association describes how the Trump tariffs could dramatically bump up the cost of your favorite electronic products. Based on analysis from the Trade Partnership Worldwide (TPW), an international trade and economic consulting firm, the latest report follows one released in January. Back then, Trump was advancing tariffs only as a threat and a bargaining ploy.

On paper, the up-and-coming Matter standard appears to be an ideal solution for smart homes: a protocol that enables the competing Alexa, Apple Home, Google Home, and other major smart-home platforms to collaborate effectively. In reality, Matter is still plagued with issues. Adding new devices to your Matter network can be a pain, and products connected via Matter sometimes "expose" only a fraction of the functionality to Matter controllers. And while Matter supports everything from smart bulbs and smart shades to robot vacuums and thermostats, one key smart home category still isn't part of the specification. I'm discussing security cameras, which are a crucial part of the smart home but still cannot connect to a Matter network.

Older Google TV and Chromecast devices are finally getting the Home Panel feature, allowing you to control your smart home devices from your TV. The feature was initially launched with the Google TV Streamer last year, but Google opened a public preview program to let users enroll older devices. Now, the feature appears to have launched widely and quietly. The latest update began rolling out earlier this week, and reports indicate users are using the Home Panel feature on discontinued Chromecast devices and Google TV sets, including Hisense TVs. Also: New Google Labs experiments help you learn new languages in'bite-sized' lessons The Home Panel on Google TV lets you control Google Home-compatible smart devices by accessing them on the right side of your TV.

Google has announced that it will no longer be bringing new Nest Thermostats to Europe due to the "unique" requirements of heating systems in the region. The company launched its redesigned fourth-generation Nest Learning Thermostat in 2024. "Heating systems in Europe are unique and have a variety of hardware and software requirements that make it challenging to build for the diverse set of homes," Google says. The third-generation Nest Learning Thermostat and the Nest Thermostat E will continue to function, receive security updates and be sold while supplies last. If you're in the market for a new thermostat that works with Google Home, though, you'll have to turn to a third-party option.

Smart LED light bulbs are one of the easiest ways to get into the IoT space. These smart lighting solutions let you control your home's illumination from your phone and other connected devices, and in addition to that practicality, they also inject some fun into your space. Color-changing bulbs have a plethora of RGB options for you to customize the lighting mood for your next movie night, date night or game day, or you can opt for cozy warm white light when you need to unwind at the end of a long day. It goes without saying that many of these smart LED light bulbs work with Amazon's Alexa and the Google Assistant, so if you already have a smart home setup in the works, you can find one that fits into your chosen ecosystem. And arguably the best thing about these devices is that they can fit into any budget; affordable and advanced options have flooded the space over the past few years. We've tested out a bunch of smart lights over the years, and these are our current favorites. If you've done any research into smart lights, you've probably come across Philips Hue bulbs.

Learning-based environmental sound recognition has emerged as a crucial method for ultra-low-power environmental monitoring in biological research and city-scale sensing systems. These systems usually operate under limited resources and are often powered by harvested energy in remote areas. Recent efforts in on-device sound recognition suffer from low accuracy due to resource constraints, whereas cloud offloading strategies are hindered by high communication costs. In this work, we introduce ORCA, a novel resource-efficient cloud-assisted environmental sound recognition system on batteryless devices operating over the Low-Power Wide-Area Networks (LPWANs), targeting wide-area audio sensing applications. We propose a cloud assistance strategy that remedies the low accuracy of on-device inference while minimizing the communication costs for cloud offloading. By leveraging a self-attention-based cloud sub-spectral feature selection method to facilitate efficient on-device inference, ORCA resolves three key challenges for resource-constrained cloud offloading over LPWANs: 1) high communication costs and low data rates, 2) dynamic wireless channel conditions, and 3) unreliable offloading. We implement ORCA on an energy-harvesting batteryless microcontroller and evaluate it in a real world urban sound testbed. Our results show that ORCA outperforms state-of-the-art methods by up to $80 \times$ in energy savings and $220 \times$ in latency reduction while maintaining comparable accuracy.
