Amazon Sidewalk is an exciting long-term effort to create a neighborhood network enabling IoT devices to work together no matter where they are, independent of any particular broadband connection.

Hot on the heels of our successful Works With Virtual Smart Home Developer Conference, we’re excited to announce a collaboration with Amazon on this promising new way for customers to ensure secure connections for smart devices anywhere on their property. 

Amazon Sidewalk is a secure, shared network created by neighbors who share a small portion of their broadband connection, allowing their devices to work better at home and beyond the front door. It is a free software application layer that works on top of any wireless solution, including Sub-GHz FSK, Bluetooth LE, and Wi-Fi, enabling IoT devices to connect to each other and through the cloud network securely.

Designed to provide the best experience for people with connected homes, Amazon Sidewalk creates a broad coverage network, ideal for low-bandwidth, low-cost devices, without requiring complex setup or maintenance. One of the most exciting things about Amazon Sidewalk is the ability for the network to extend beyond individual properties to the global Sidewalk network with a range similar to cellular networks.

Jamie Siminoff, founder & chief inventor of Ring, discussed Sidewalk during his feature keynote during our Works With 2020 virtual smart home developer conference. A replay of Siminoff’s keynote is available here and can be viewed by registering for free on the Works With conference website here. Amazon employees also recently demonstrated the capability of Sidewalk by installing 700 Ring lighting products around their homes; in just a few days, the individual network points combined to support a secure low-bandwidth 900 MHz network covering a large portion of the Los Angeles Basin.

Silicon Labs’ EFR32 Wireless Gecko Series 2 family of products will work seamlessly with Amazon Sidewalk when Sidewalk SDK is launching later this year. This launch will enable developers to create IoT products that can securely communicate to the cloud, regardless of which wireless protocol is used.

We’re looking forward to all of the possibilities Amazon Sidewalk will offer and cannot wait to see what our customers develop with this exciting new technology. For more information on how to get started with Sidewalk, contact your local Silicon Labs Sales Representative.

Wow, what a great event our first-ever Works With smart home developer conference was!  It was simply awesome to see so many companies and industry sectors all coming together under one virtual roof to learn and discuss all things smart home and IoT.

With more than 6,000 registered attendees, seven excellent keynote speakers, and a ton of high quality developer-oriented educational sessions, there was a LOT to take in at Works With.  Fortunately, anything you may have missed is available to see replayed on-demand via the Works With site so long as your register (which is free). In every session I visited, the live Q&A on Slack was very busy - a great sign that Works With attendees were fully engaged with the content.

I was fortunate enough to be able to experience many different aspects of the Works With event, and three big themes stood out:

1. Ease of development
2. Interoperability
3. Security

Ease of Development

Being able to easily and efficiently reuse development effort on one project when starting the next project came up in many places during the conference, not least of which was in the Amazon keynote.  When companies develop scalable, versatile platforms that work on standards and incorporate common API's and/or data flows, this effectively enables developers to focus their valuable time on adding innovation in the areas that are most important to them and their products. That is how truly special products are made!

Project Connected Home over IP (CHIP) generated a lot of interest, as the Zigbee Alliance project is a big deal in making interoperability easier to achieve across smart home devices. The project now has 145 member companies and over 1,300 people around the globe participating and contributing to its mission. The project has an open approach to development - open project and open source (all on GitHub), so it's very easy to access and start to engage with. 

The first devices CHIP is focused on include smart lighting, HVAC controls, window covers/shades, gateways, and others to build momentum in both smart home and smart buildings. Sujata Neidig, who represented Project CHIP in a Works With panel discussion hosted by Stacey on IoT's Stacey Higginbotham, announced that we should expect to see the first products built on CHIP appear in the market this time next year. Be sure to check out our EFR Series 2 parts to get your CHIP development going! 

Interoperability

The standardized models in Project CHIP should make it much easier for device manufacturers to build connected products that can fit very well into a wide variety of use cases and ecosystems. This means it becomes so much easier for consumers to choose what to buy and to get their smart home devices up and running instantly. That's a big win-win for everyone! 

Another one of the sessions I joined on interoperability was on the Google technical track, called "Introduction to Google Ecosystem." It was great to see how easy it is now to create a door lock example running on our EFR32MG21 development platform using OpenWeave and seamlessly integrate that into the Google Ecosystem. It truly demonstrates how these initiatives, like Project CHIP, are revolutionary in terms of interoperability.  

We've now established that easy development and reuse of technology combined with interoperability leads to rapid growth in the IoT and to building things we can't even imagine yet. BUT - consumers must be confident IoT devices can be trusted to keep their personal information private and secure, which in turn means that the security embedded in these connected products has to be strong.

Security

Getting IoT security right is a big deal and doing so successfully is not an easy thing to achieve.  At Silicon Labs, we have been investing in IoT security for quite some years as we saw the need for this coming. In a keynote from our head of IoT, Matt Johnson, Works With attendees heard about our EFR32 Series 2 devices earning both Arm's PSA-2 and IoXt Alliance's SmartCert IoT security certifications. For PSA-2, the EFR32MG21 with Secure Vault is the first wireless SoC ever to achieve this level of certification!  We are committed to making security accessible and easy for developers to implement by embracing standards and leading the way for secure IoT connectivity. In doing so, we believe more and more IoT developers will include security by default into their products, thus making it easier for consumers to trust their data is safe in an IoT device.

Another highlight for me was the opening keynote on Works With Day 2 with Ring founder and CEO Jamie Siminoff. It was great listening to his story and the passion he has for advancing IoT and making a positive impact on the way we all live. Jamie shared the latest on Amazon's Sidewalk effort, which stands out as a great example of how IoT can improve the way we live. Jamie described Sidewalk as a 10+ year project for Amazon, which builds on the idea of neighborhood: sharing with neighbors but with an IoT tech twist: the more connected devices your neighbors have in the network, the more everyone benefits. I loved the 'Fetch' example Jamie shared, which is an Amazon ultra-low-power play to be able to track your dog throughout the neighborhood if it escapes! Nodes around the neighborhood track and help pet owners locate their lost dog. To me, this is a simple yet really tangible way of showing how IoT tech, such as 'roaming' within Sidewalk, helps to make the IoT super-valuable to us all.

These past two days have been jam-packed with a ton of great content, and I want to thank all the people and teams involved in preparing and presenting the material. From our internal marketing and apps teams, our design partners, and our customers - all have played a huge role in making this event such a great success! But I'd also be remiss if I didn't give a massive shout out to the Silicon Labs production team who worked tirelessly behind the scenes to evolve what was originally planned as a big 'in-person' event into a huge virtual one! We ended up connecting a much bigger audience than initially planned by going virtual. We did so in a very slick, easy to consume way - bringing together all parts of the IoT industry and fostering great collaboration and innovation in a space that's more relevant now than ever before.

What we are doing at Silicon Labs is striving to make everything work with everything and do so in a way that has a positive impact on everyone's quality of life. We are THE place to go if you want to enable IoT connectivity, and we'd love to talk with you about how we can help bring your next IoT products come to life. If you'd like to start that conversation, we are waiting to hear from you. Simply send us a note here, and we'll be in touch!

Today, Silicon Labs kicked off its first-ever smart home developer event, Works With 2020, featuring industry experts and leading engineers sharing the latest in smart home technology development. Works With is the first of its kind to host developers and ecosystem partners, delivering 40 engineering-led session and 15 workshops to aid developers with designing, prototyping, and getting their products to market. When Silicon Labs imagined Works With, it wasn’t envisioned as a livestreamed event, but shifting to virtual allowed more than 5,000 developers from all over the world to participate.

Day 1 Recap - It’s All About Connections

Opening Keynote

Silicon Labs CEO, Tyson Tuttle, kicked off the event by diving into Silicon Labs’ vision to build a smarter, more connected world. With the current global pandemic, now more than ever, people are depending on IoT technology to stay connected – to work, to fun, and to each other. The creative ideas of developers are key to the success of the smart home industry.

Tyson went on to speak about Works With being the “Smart Home Hub” – a place where major platform players, protocol experts, and alliance partners unite to help developers navigate smart home technology. The event is designed to bring together all developers, no matter their level of expertise, and provide the know-how and best practices to get certified smart home products to market quicker. Tyson welcomed Silicon Labs IoT SVP and GM Matt Johnson to the keynote stage where he spoke to Grant Erickson, Jim Kitchen, and Joshua Danovitz, who are leading efforts at their respective companies, Google, Comcast, and Amazon, to pioneer a smoother development journey and break through the standards fragmentation in order to bring new and differentiated features to consumers.

Technical Sessions

After the keynote, attendees broke out into a variety of technical sessions, including workshops on designing products that work with Amazon, Google, HomeKit, and Samsung SmartThings ecosystems. During the sessions, developers had the opportunity to hear directly from engineering experts about the latest and greatest in smart home development. The sessions also gave developers the opportunity to learn how to acquire industry-recognized certifications for their products.

Panel – Building an Ecosystem IoT Developers Will Love

During lunch, technology journalist and IoT thought-leader Stacey Higginbotham (of Stacey on IoT) hosted a panel with leaders from NXP, ADT, Philips Hue, Ikea and Assa Abloy where they discussed how the smart home industry is coming together and how it will continue to evolve.

The panel discussed at length the emphasis on matters related to security and user experience, and one of the main points was the focus on leveraging the IP investment companies have already made. Being able to use existing IP bearing networks and shifting development resources to focus on actually innovating on new features that add value and simplify adoption for consumers.

Panelists also touched on some of the biggest obstacles developers face in bringing their products to market, including the effort required to support so many different protocols and delivering consistent user experiences across brands. Answering these challenges will provide developers with the confidence to build new, more sophisticated feature sets that create better experiences and simplify adoption.

Aside from personal electronic devices (PEDs), smart doorbells are a logical entry point for consumers into the world of IoT devices. In particular, with the COVID-19 pandemic forcing many of us to shift our shopping online, knowing who might be lingering on your front porch is suddenly a pretty important feature. What started as an idea to reduce crime in neighborhoods soon became the vision of making people’s lives better by bringing security to their doorstep. As highlighted in his 2019 TEDx event, Jamie Siminoff – CEO, Founder, and Chief Inventor of Ring – shared best practices around building technology around communities. His keynote at Works With 2020 will inspire developers to create and build products that revolutionize smart homes around the world.

Ring has become a dominant name in Wi-Fi-enabled video doorbells, and Jamie has one of the most engaging entrepreneur stories in technology. Developed in Jamie’s garage in 2011 and acquired by Amazon in 2018, Ring has become one of the most sought-after products in the Amazon ecosystem. Jamie continues to lead Ring as it innovates and leads the way in home security. His story is one of tenacity and patience, and his vision for Ring’s future with Amazon is as ambitious as it is promising.

Prior to Ring, Jamie founded several successful ventures, including PhoneTag, the world’s first voicemail-to-text company, and Unsubscribe.com, a service that helped email users remove commercial email from their inboxes. He successfully sold both companies in 2009 and 2011 respectively.

In 2013, Jamie pitched Ring – then known as DoorBot, on Shark Tank, where the investors liked the idea, but not enough for any of them to invest in the start-up. At the time, Mark Cuban said of Ring, “I think it’s a great business. I think you’ll be successful. It will be worth $20 million. I just can’t invest in something that’s not going to be $70 million someday.” During that presentation, Jamie was offering a 10 percent stake in the company for $700,000. Four years after his appearance, the Sharks were asked on an ABC News special about some of the ideas they regret letting slip away, and Ring was at the top of their list. Less than a year later, Amazon acquired Ring – its second-largest purchase behind Whole Foods.  

Jamie will be joining the Works With keynote stage where he’ll accompany Silicon Labs IoT SVP and GM Matt Johnson to kick off the second day of the event. You can catch the Day 2 Keynote on Thursday, September 10, at 9:00 a.m. CDT. Click here to register.

As organizations seek strategies to keep people safe while balancing the need to operate their businesses, wireless temperature sensors are seen as a way to make processes as contactless as possible. As the world moves into month five of the COVID-19 pandemic and the practicalities of emerging from various stages of safe isolation are being addressed. From essential businesses that have remained operational to schools and universities facing the prospect of returning to classes in the Fall, mitigating the risks that come with large gatherings is at the top of everyone’s list of priorities. Administrators and managers can take appropriate measures, starting with an economical, easy-to-use, and ultra-fast method for detecting potential health risks, to balance the anxiety that comes with possible exposure with the pressures of keeping businesses, schools, cities, and economies up and running.

One way this challenge is being met is through technology. Silicon Labs is excited to be part of a coordinated effort to develop a low-cost, contactless wrist temperature sensor that can be used to determine whether or not an individual is within the acceptable temperature range. Screening individuals for fever is a strategy that’s been deployed by organizations when isolation or social distancing simply isn’t an option. And while there’s so much we don’t know about COVID-19, temperature checks may be an effective way to identify a symptom even before the individual experiences any symptoms.

The TTI Family of Companies (FOC), which includes Connected Development, Symmetry, and Mouser, together with TE Connectivity, have joined forces to develop an open-source, contactless wrist temperature sensor. Cost-effective and easy to use, the temperature sensor is based on the Silicon Labs EFM32 Tiny Gecko TG11 Starter Kit, which is used to collect temperature sensor information from the thermopile and to notify the end-user of results.

The contact sensor is already being used by TTI employees at its warehouse locations where employees entering the facility simply hold their wrist near the sensor. They receive an instant reading of their temperature, which is accompanied by beep noise and a red or green light indicating if they are at or above the acceptable temperature range. Connected Development (CD) designed and prototyped the sensor; they specialize in hardware and software design services. CD tapped into TTI FOC’s extensive network of component distributors and services, with contributions from TTI, Symmetry Electronics, and Mouser Electronics, to develop this open-source design.

In addition to the Silicon Labs Tiny Gecko Starter Kit, the sensor design features a TE TSD305 Digital Thermopile Sensor for temperature measurements, a TDK Piezoelectric Buzzer for audio feedback, and Cree PLCC6 3 in 1 SMD LEDs provide the visual cues. Aside from body temperature, the thermopile sensor can also detect when a person is within range to take a measurement. The Tiny Gecko constantly regulates the thermopile for temperature fluctuations, and if the temperature rises above 90 degrees Fahrenheit, it is assumed that a human body is close by, prompting a measurement cycle to begin. The microcontroller then awaits a consistent measurement, which is achieved by capturing three readings in a row that are within one degree of each other. Once a stable measurement is captured, the temperature is displayed on the starter kit’s LCD. The TDK Piezoelectric Buzzer then sounds, which is accompanied by a green light from the Cree LEDs if the temperature is below 100.4 degrees Fahrenheit, or a long beep with a red LED light if the temperature is higher than 100.4 degrees Fahrenheit.

If you’re considering developing a contact sensor to help bring clarity to the health of your workforce, there are a couple of different ways we can help you realize that goal. The first is during the first-ever Silicon Labs Works With Smart Home Developer Event. David Hoover, VP of Advanced Development at Connected Development, will be presenting a tutorial showing how to interface a TE thermopile sensor with the EFR32xG22 Wireless Gecko Starter Kit, which includes all you need to create a Bluetooth connected device. David will also demonstrate how to use Silicon Labs’ Simplicity Studio to send the resulting temperature to an IOS device using Bluetooth services and characteristics. The first Works With virtual event, taking place on September 9-10, will bring together our ecosystem of partners from Amazon, Google, Samsung, Z-Wave, and more for keynotes, panels, and hands-on workshops.

If you can’t attend the workshop, our friends at Mouser Electronics have developed a detailed, step-by-step technical article on how to develop the contact sensor, calibrate it, and start using it. You can also explore open-source contactless sensor documentation on GitHub.

IoT protocols such as Wi-Fi, Zigbee, Z-Wave, Thread, and Bluetooth are all networking technologies that make it possible for IoT products to communicate and work with other platforms, devices, and applications. We rely on these wireless protocols to specify the rules that establish and manage networks and transmit data.

In keeping pace with rapid advances in smart home development, Works With, the smart home developer conference, will feature training and how-to tutorial sessions designed to accelerate IoT development across platforms. With built-in essentials for IoT wireless already implemented into the stack, developers can focus on application development and not spend time worrying about lower-level network details.

To get started with smart home development, check out the featured sessions covering IoT protocols training sessions. But first, we will define what an IoT wireless protocol is.

What is an IoT Wireless Protocol?

IoT wireless protocols specify the rules and formats to manage and transmit data across networks so that devices, gateways, and applications ‘speak’ to each other.
