Shelly announced the Presence Gen4, a camera-free mmWave radar sensor that the company says can detect up to 10 people at once. It is available from Shelly for $84.99 and supports customizable detection zones and several smart home platforms.
Shelly announced its Presence Gen4, a camera-free sensor that uses mmWave radar to detect the presence, movement and activity of people and pets, with the company saying it can track up to 10 people simultaneously. The device costs $84.99 through Shelly’s online store and is designed to trigger smart home automations across rooms or larger spaces.
The Presence Gen4 uses mmWave radar rather than a camera. Shelly says the sensor can monitor an area of up to 650 square feet and has a 140-degree horizontal field of view. It can sit on a shelf or table using its built-in stand, or be mounted on a wall. It needs a nearby power source for its USB-C cable.
Users can configure as many as 10 independently customizable detection zones. For example, a zone could be set to switch on a desk lamp when someone sits at a desk, while another could trigger a home theater when someone occupies a sofa. The sensor can also be configured to include pets or to ignore low objects, which may help prevent a robot vacuum from triggering an automation.
Shelly says the device works with Google Home, Apple Home, Amazon Alexa, Samsung SmartThings and Home Assistant. Its listed connectivity options include Wi-Fi, Bluetooth, Zigbee and Matter. The report says the product is available through Shelly’s store, with Amazon and Best Buy availability expected later.
Radar-Based Room Automations
The sensor gives smart home users a way to trigger actions based on where people are in a room, rather than relying only on a door sensor or broad motion detection. Shelly’s examples include switching lights, heating, cooling or music on when someone enters an area and off when they leave. Custom zones could make those actions more specific to a desk, sofa or other part of a room.
Because the device uses radar instead of a camera, it offers a camera-free option for presence detection. The source report does not establish how the device processes or stores detection data, so the absence of a camera should not be read as a full account of its privacy practices. Its listed compatibility with several major smart home platforms may also matter to households that want the sensor to work alongside existing devices.

From Entry Detection to Presence
Shelly introduced the Presence Gen4 after launching a $50 subscription-free security camera the previous month, according to The Verge. The new accessory serves a different purpose: detecting people, movement and activity in indoor spaces to support automation, rather than recording video.
Presence sensors can help systems distinguish whether a room is occupied, while motion sensors generally react to movement. The report describes Shelly’s device as able to follow multiple people and support separate detection zones. Its stated coverage, setup requirements and platform support are product details reported at launch; independent performance testing was not included in the source material.
“The sensor can detect up to 10 people simultaneously.”

Performance and Data Practices
The source report does not provide independent tests of the 10-person detection claim, the stated 650-square-foot coverage or how reliably the sensor distinguishes people, pets and low objects in different room layouts. It also does not explain what data the device processes, whether any detection information is stored, or how those settings can be managed.
The report says Amazon and Best Buy availability is expected, but gives no dates for those listings. Regional availability and whether all listed integrations and connectivity options are available at launch are also not specified.
Retail Availability and Testing
Shelly’s online store is the reported launch channel, with Amazon and Best Buy sales expected later. The company has not provided a retailer launch date in the source material. Further product details or independent reviews may clarify real-world detection range, accuracy, setup and data handling.
