Last year, we told you that we are transitioning to an API-first SmartThings platform. As a part of this, we started investing deeply in improving stability and security. We are excited to announce the beta release of SmartThings Edge, a new architecture for hubs that uses device drivers and rules to execute hub-connected devices locally.

What is SmartThings Edge?

We are taking smart home events that would have happened on the SmartThings Cloud and moving them to your SmartThings Hub. SmartThings Edge uses Lua©-based device drivers and our Rules API to control and automate devices connected directly to a SmartThings Hub. This includes Zigbee, Z-Wave, and LAN devices as well as automations triggered by timers and other hub-connected devices using drivers. In the future, this will expand to include more protocols and features, like the new Matter standard.

For users, edge processing means reduced latency. For partners and developers, SmartThings Edge also brings new benefits, including reduced cloud costs, an improved device permissioning model, and the ability to deploy updates to their drivers. Local device support is open to everyone—not just WWST partners—enabling easier device support and integration with standard capabilities.

Hub-Connected devices are defined by a driver package that includes the fingerprints, components, preferences, and Lua source code. With this beta release, you can start testing features and providing us feedback before we start the platform migration. As a WWST partner, you can create your own driver package or add your device’s fingerprint to our predefined supported drivers.

Building Hub-Connected Devices

Sample-Driver-Code
To get started, all you need is a SmartThings Hub with firmware version 000.038.000XX or greater and a Zigbee, Z-Wave, or LAN device. Visit the SmartThings Community to learn how to get started with the SmartThings CLI and building drivers.

Rules and Automations

Local-Automations-Icon
As part of our June SmartThings app release, you may have noticed that some of your automations show a little 🏠. This means the automation is using locally-executing conditions and actions, such as time of day. As your devices begin using drivers and compatible rules, they will begin running on your hub, meaning higher reliability and faster response times.

We have started expanding the Rules API to include new operations, including: risesAbove / dropsBelow, risesToOrAbove / dropsToOrBelow, and securityState. To learn more, visit these sample rules.

Sharing and Distribution

Previously, sharing device type handlers (DTH) required end-users to copy and paste the code for each individual DTH into their accounts. This could be confusing and time-consuming for users to ensure they had the latest updates installed. With SmartThings Edge, we are also introducing driver sharing for device testing and community distribution.

OEMs can submit their drivers to SmartThings for WWST certification and distribution in the SmartThings catalog. However, hobbyists can now share custom devices with a simple link—no need to copy and paste code! Learn more about driver sharing and how you can start testing Edge drivers.

Getting Started

Documentation-Portal
Along with this launch, we’ve also released a new Developer Documentation Portal.

To learn more about building SmartThings Edge devices and automations, check out our new developer documentation portal. This includes a new Capabilities Reference Guide that clearly delineates between live, proposed, and (soon-to-be) deprecated capabilities. Visit the new Documentation Portal and the SmartThings Community for tutorials, code samples and more.

      The Galaxy S22 series has been a bittersweet success for Samsung. The phone brought back the Note series as the Galaxy S22 Ultra, and the entire S22 line saw great sales initially. But soon after launch, buyers discovered the Exynos 2200 versions of the phone came with performance throttling and benchmark cheating. The Galaxy S23 will be spared such shame next year, with Samsung reportedly using just one chip: Qualcomm’s Snapdragon 8 Gen 2.
      The Galaxy S22 throttling issue turned into quite a scandal in Samsung’s home country. The Exynos 2200 was hardly the success that Samsung wanted it to be. The throttling helped Samsung reduce overheating and preserve battery life. But it also meant the Galaxy S22 wouldn’t perform like a true flagship.
      Samsung had to apologize to shareholders and customers and faced lawsuits and investigations in Korea. Furthermore, the company had to dispel accusations that it had cut corners designing the Galaxy S22. And it pledged to create a high-end chip to power flagship phones in the future.
      That won’t be the Exynos 2300, if the following claims pan out. Ming-Chi Kuo believes the Galaxy S23 series will only use Qualcomm’s next-gen chip.
      Galaxy S23 to run on the Snapdragon 8 Gen 2 chip
      Kuo is an insider known for his accurate Apple-centric leaks. He usually details the iPhone and other unreleased devices. But he recently addressed the Galaxy S23 series, releasing a few predictions on Twitter.
      According to him, Qualcomm will be the sole processor supplier for the Galaxy S23 series after accounting for 70% of Galaxy S22 chip shipments. Kuo says the SM8550 will be Qualcomm’s next chip, built on TSMC 4nm process. The insider doesn’t mention the name of the processor. But we’re probably looking at the Snapdragon 8 Gen 2.
      Kuo said the Exynos 2300 “can’t compete” with the SM8550. Therefore, The Galaxy S23 will get the Snapdragon 8 Gen 2 chip.
      Moreover, the leaker said that the new Qualcomm chip has “obvious advantages” over its Snapdragon 8 Gen 1 predecessors regarding computing power and efficiency.
      Galaxy Z Fold 4 to have a similar fate
      A different insider recently described a similar strategy for the Galaxy Fold 4 and Flip 4 foldables coming in the second half of the year. Samsung will only use the newer Snapdragon 8 Plus Gen 1 chip in those devices. That means buyers will not risk running into the Exynos 2200 version of the two foldables this year.
      Qualcomm’s new Snapdragon 8 chip variation will power other 2022 Android flagships in the coming months. The Plus variant should be more powerful and efficient than the regular model.
      That said, it’s too early to tell what the Snapdragon 8 Gen 2 will bring to the table. Qualcomm will unveil the new chip closer to the end of the year. As for the Galaxy S23 series, we don’t expect Samsung to unveil the phones until the first months of 2023.
      The post Galaxy S23 might dump Exynos for Qualcomm chips next year appeared first on BGR.

      The Samsung Foundation of Culture established the Leeum Museum of Art in Hannam-dong, Seoul, Korea in 2004 in order to preserve its cultural assets and share them with the public. It was designed by acclaimed architects, Mario Botta, Jean Nouvel and Rem Koolhaas, and is highly regarded for its architectural value and harmonious design which blends with nature. With its unfailing dedication to holding exhibitions and showcasing its expansive collection, the museum now has one of the most broadly representative and varied collections in South Korea. Today, the Leeum is known as an open museum where various artistic styles, from traditional Korean art to vibrant and modern contemporary pieces from both Korea and abroad, can coexist. The museum has also been utilizing digital technology in its exhibits for the past ten years with this technology allowing, old artworks to be displayed in new and exciting ways. In this way, the Leeum seeks to head toward the future while not forgetting about the past. The museum is currently using a variety of state-of-the-art devices for both exhibition and education purposes.

      A few days ago, Samsung warned investors and fans that the current chip shortage might prevent it from launching a new Galaxy Note smartphone this year. But there was no evidence that Samsung was actually developing a Note 21 phone before the company said the chip shortage could impact smartphone production. Early rumors always seem to reveal specs and design choices for the next Galaxy flagship well before the phone is ready to launch. That hasn’t happened with the Note 21 series. If anything, longstanding rumors said that Samsung would cancel the Note series, which is increasingly difficult for Samsung to differentiate from its Galaxy S phones. The Galaxy S21 Ultra is the best proof of that. It features a large display and supports the S Pen. Screen size and stylus interaction were the signature features of the original Note.
      Various rumors also claimed that Samsung might replace the Note with the obvious choice that would keep the Note legacy intact. A foldable phone would offer a bigger display than traditional smartphones and could continue to support S Pen functionality like the Note. A new report from Asia says that Samsung is indeed looking to diversify and expand the foldable phone lineup for 2021 by launching a third device that would fold not once, but twice. The double-folding phone would join the Galaxy Z Fold 3 and Z Flip 2 phones that are both still expected to launch later this year.

      Sources familiar with Samsung’s plans told Nikkei Asia the Samsung aims to increase foldable phone production “sharply,” despite chip shortages. Samsung also aims to make up for the lost Note sales with foldables, hopefully increasing revenue in the process. Samsung sold an estimate of 3.5 million foldable handsets last year, and wants to raise that figure to over 10 million a year in the near future, which would match Note sales.
      People who claim to be familiar with Samsung’s plans said that “the suspension of the Note series was pretty much decided last year. The company wants to bet more on foldable phones that have much higher prices with distinctive designs.”
      A different person said that Samsung has “long struggled to differentiate its two premium phone series, the Galaxy S and Note, which are often set for the first half of the year and the second half, respectively… The company is thinking to use foldable phones as a key differentiator and hopefully to replace its Note series in some ways.”
      A double-folding Galaxy phone wouldn’t necessarily be a surprise. We’ve already seen several patents from Samsung detailing such devices. The handset would feature two hinges instead of one. When unfolded, the device would offer users even more screen real estate than the Galaxy Z Fold. And a smartphone design like this could potentially replace the Note. This year’s foldable Galaxy handsets are supposed to feature S Pen functionality, according to rumors.
      Nikkei makes no mention of the stylus but offers other details about the double-folding handset. “The design is set to make the unfolded screen aspect ratio be in line with the mainstream ratio of 16:9 or 18:9, so more video games and other apps could run more smoothly with better resolutions on the device,” according to a person with knowledge of the matter.
      The Galaxy Z Fold 2 has a 25:9 aspect ratio, making it harder to develop apps that take advantage of the whole screen. On the other hand, Samsung has always stressed that the bigger display can be split between different apps to enhance multitasking.
      According to the report, the unnamed double-folding Samsung phone will be unveiled as early as late-2021. Samsung usually launches the new Note flagships during an Unpacked event set in early August. It’s unclear when the 2021 Galaxy Z Flip and Fold versions will be announced.
