What is Matter and why does it matter?

Matter will help make buying smart home products more accessible than ever.

When it comes to buying smart home products, it's not always cut and dry. Support for certain items can often be limited to one ecosystem, meaning you can't just pick up a smart appliance and trust that it'll just work with whatever you're using. But that's about to change, thanks to Matter. Formerly called Project CHIP, Matter is set to change things in a way that will make it easier than ever to establish the ultimate smart home.

But what exactly is Matter? Also, what is Thread, and how does that fit into everything? Will current devices work with the new standard, or will we have to buy entirely new products?

What is Matter?

Matter generally refers to the new smart home connectivity standard created by a working group of over 200 companies and founded by the Connectivity Standards Alliance (CSA), formerly Zigbee Alliance. It uses Internet Protocol (IP) such as Bluetooth LE, Wi-Fi, and Thread to make smart home products compatible with each other using a single standard instead of the many disparate standards that exist today.

The Matter Working Group is also taking an open-source approach to developing the SDK, which will enable companies to bring products to the market faster once it's complete.

This will make it easier for companies and developers to build smart home appliances and Internet of Things (IoT) devices that seamlessly work together, regardless of the brand. That means Matter-certified products will work with Google Home, Amazon Alexa, Apple Homekit products, Samsung SmartThings, and much more. This will also simplify the buying process for both retailers and consumers who can have solace knowing that even the best smart home products will support their ecosystem.

What is Thread?

Thread is a wireless mesh protocol similar to Wi-Fi and Bluetooth that enables seamless communication between devices. It is based on IPv6 and uses an edge router, or "border router," to connect that network to other networks like Wi-Fi, Ethernet, and the cloud. Thread serves as the connection between the devices, while Matter is the language that these devices will use to communicate and sits on top of Thread as an application layer.

The group responsible for the protocol boast that Thread networks have "no single point of failure and include the ability to self-heal." This is because all the devices on the network can communicate with each other as opposed to having one centralized controller like other protocols. That means that if the Leader router fails, another router will take its place in the network.

Devices using Thread are simple to set up, and most are automatically configured. Thread also supports full end-to-end encryption between all devices; that means device-to-device, device-to-mobile and remote devices, and device to any cloud service.

What companies are involved?

There are more than 200 companies involved in the Matter Working Group, meaning there will be plenty of products that will support the new standard. Some of the biggest names in the smart home industry are involved, including Google, Amazon, Samsung, and even Apple.

These companies have already pledged their support for Matter and Thread on current or future products. Amazon says it will bring support to some of its existing Eero and Echo products, starting with the Echo (4th Gen) and expanding to other devices afterward.

Google will integrate Matter with Android and Nest to ensure that device setup is quick, easy, and seamless. Some products like the Nest Hub (2nd Gen) will support Matter over Thread, while others will support Matter via Wi-Fi.

This highlights that not every product updated to support Matter will include Thread support, which may be an important distinction. Either way, it's good news for users that are already invested in the Nest ecosystem ecosystems.

Samsung has also pledged support for Matter in its SmartThings platform. However, the company hasn't specified which devices will receive support, saying that it will "bring Matter to multiple products in 2022."

Other manufacturers for smart home items such as Philips, Ikea, and many more have also pledged to update their current devices to support the new standard.

When will Matter-certified devices be available?

Matter Smart Home Branding

Earlier this year, a timeline was set to have products through certification by the end of the year. These devices would carry the Matter brand, making them easily recognizable for retailers and consumers.

However, the timeline was recently updated, signaling a delay in the process that wouldn't see the SDK finished nor the first device certifications occur until the first half of 2022. This means we may not see Matter-certified products reach the market until the second half of 2022.

Tobin Richardson, president and CEO of the CSA, said that the delay was a necessary move, "ensuring that the SDK, and related tools, are ready to meet the expectations of the market when launched and enable a large ecosystem of interoperable Matter products."

Uber Eats exits seven markets, transfers one as part of competitive retooling

Uber Eats is pulling out of a clutch of markets — shuttering its on-demand food offering in the Czech Republic, Egypt, Honduras, Romania, Saudi Arabia, Uruguay and Ukraine. It’s also transferring its Uber Eats business operations in the United Arab Emirates (UAE) to Careem, its wholly owned ride-hailing subsidiary that’s mostly focused on the Middle East. “Consumers and restaurants using the Uber Eats app in the UAE will be transitioned to the Careem platform in the coming weeks, after which the Uber Eats app will no longer be available,” it writes in a regulatory filing detailing the operational shifts. “These decisions were made as part of the Company’s ongoing strategy to be in first or second position in all Eats markets by leaning into investment in some countries while exiting others,” the filing adds. An Uber spokesman said the changes are not related to the coronavirus pandemic but rather related to an ongoing “strategy of record” for the company to hold a first or s

This popular open-source web server has some serious security flaws

OpenLiteSpeed Web Server, a globally popular open-source web server , was carrying a couple of high-severity vulnerabilities, experts have warned. Threat actors that managed to exploit these flaws would have been given full privilege remote code execution capabilities, noted researchers from Unit 42, Palo Alto Networks’ cybersecurity research arm.  The team found OpenLiteSpeed Web Server carried three high-severity vulnerabilities, namely CVE-2022-0073 (an 8.8 severity score, high-severity remote code execution flaw), CVE-2022-0074 (an 8.8 high-severity privilege escalation flaw), and CVE-2022-0072 (a 5.8, medium-severity directory traversal flaw). The vulnerabilities also affected the enterprise version, LiteSpeed Web Server. Patch ready Unit 42 has notified LiteSpeed Technologies of its findings which has, subsequently, patched the flaws, and released new versions of the server, urging users to update their software immediately.  Organizations using OpenLiteSpeed versions 1.5.1

These Android games support Bluetooth controllers and they're better for it

Gaming is simply better with a controller in your hands. Gaming on Android typically requires you to settle for using touchscreen controls.
