Remember Sidewalk, Amazon’s “neighborhood” network that leverages nearby Echo speakers and Ring cameras to connect smart devices that would normally be out of Wi-Fi range? After years of quietly brewing, Sidewalk is back in a big way, with Amazon-owned Ring hard-launching a series of new Sidewalk-enabled sensors, controls, and smart plugs at CES today. Among the Ring devices making their debuts in Las Vegas include door and window sensors, motion detectors, panic buttons, smoke and carbon-monoxide “listeners,” floor and freeze sensors, and air-quality monitors, along with a smart plug, a smart light switch, and even a car alarm. Separately, Ring announced new AI-powered alerts designed to notify you of “out of the ordinary” home events as well as “Active Warnings” about potential threats. These “AI Unusual Event” alerts and “Active Warnings” are coming later this month and will require a “compatible” Ring subscription, according to Ring’s press release . Also coming soon is a new app store for the Ring app , offering a wide variety of integrations from third-party developers that provide functions ranging from monitoring your pets’ health to tracking whether your pool needs cleaning. But let’s jump back to the new Sidewalk devices, with Ring announcing three categories of Sidewalk products, including security-minded sensors, safety detectors, and control-oriented devices. Among the security devices is the Ring Window & Door Sensor ($29.99), which, like all of Ring’s product announcements today, requires an Amazon Sidewalk bridge. If you own an Amazon Echo speaker or a Ring camera, you’re probably covered already. Ring There’s also the Motion Detector ($39.99), the Glass Break Sensor ($39.99), an Outdoor Door Sensor ($39.99), and the Panic Button ($29.99), which lets you summon your emergency contacts when you press it. Ring’s new safety-minded devices include the Smoke & CO Listener (which keeps an ear out for smoke and carbon monoxide sirens, priced at $39.99), the Flood & Freeze Sensor ($39.99), the Temperature & Humidity Sensor ($39.99), the Air Quality Monitor ($69.99), and the Sump Pump Monitor ($39.99). For smart control devices, Ring is serving up Sidewalk-powered smart plugs ($24.99 each), a Smart Light Switch ($29.99), a Smart Fan Control ($39.99), and a push-button Smart Light Remote ($29.99). Finally, Ring has unveiled the Sidewalk-enabled Ring Car Alarm ($49.99), which it developed in partnership with Cambridge Mobile Telematics. Ring The new Sidewalk-enabled Ring sensors and control devices will ship in March, while the Ring Car Alarm is already up for pre-order . First announced back in 2019, Amazon Sidewalk uses a combination of Bluetooth Low Energy (BLE), 900MHz radio spectrum, and other wireless frequencies to allow multiple nearby Ring, Echo, and other compatible devices to work together, creating a low-power, long-range network large enough to cover an entire neighborhood. Such a “neighborhood” network is ideal for low-bandwidth devices such as smart sensors, motion sensors, light switches, and all the other types of smart products that Ring is announcing today, as it gives them connectivity in places outside the home that are well out of Wi-Fi range. Amazon Sidewalk relies on Echo and Ring devices throughout the neighborhood to create the network. Sidewalk is an opt-out feature—meaning, it’s turned on by default—and as such, it raised the ire of Echo and Ring users worried about privacy and concerned that Sidewalk was siphoning off their bandwidth. Amazon says it has enabled a raft of security measures designed to protect the privacy of both Sidewalk bridge owners as well as passersby with devices that can connect to Sidewalk. After a slow start, more and more Sidewalk networks have been popping up from coast to coast. Amazon lent me an antenna a few years back that allowed me to see all the nearby Sidewalk networks in my area, and there were a lot of them. Amazon says it will begin a global Sidewalk rollout later this year, starting with the E.U., the United Kingdom, Australia, New Zealand, and Japan.
