Shelly has released the Presence Gen4, its first mmWave radar presence sensor, in North America for a suggested retail price of $84.99. The company says it can track up to 10 people across 10 customizable zones and supports Matter, local control and multiple smart-home radios.
Shelly has released the Presence Gen4, its first mmWave radar presence sensor, in North America, introducing a device the company says can detect up to 10 people across 10 customizable zones. The sensor supports Matter and local control, allowing compatible smart-home systems to use room occupancy as an automation trigger without relying on a cloud connection.
The Presence Gen4 uses mmWave radar to detect presence and small movements, including when a person is still. Shelly says its app can show occupancy by defined space, and the sensor can trigger actions when people enter or leave a zone. That could be used to control lights, heating and cooling, curtains or other connected devices according to where people are in a room.
The device supports Wi-Fi, Bluetooth and Zigbee, alongside Matter. The source report lists compatibility with Google Home, Amazon Alexa, Apple Home, Samsung SmartThings and Home Assistant. Shelly also supports local control and custom scripting. Its suggested retail price is $84.99, and the report says it is available through Shelly’s North American store, with Amazon availability also noted.
Shelly lists a 140-degree horizontal field of view and coverage of up to 650 square feet when wall-mounted. Corner mounting narrows the field to 90 degrees, with coverage of up to 525 square feet. The compact sensor measures 64 by 41 by 26 millimeters; a built-in stand changes its dimensions and can help with positioning. It is powered over USB-C, so placement depends on access to a suitable power source.
Zone Tracking for Home Automations
Presence detection can make automations respond to whether someone is actually in a space, rather than only to movement. A conventional motion sensor may stop registering a person who remains still; mmWave sensing is intended to detect subtle movement and maintain presence detection. If it works reliably in a particular room, that could make lighting or climate controls less likely to switch off while someone is still there.
The 10-zone design also offers more specific triggers than a single room-wide occupancy signal. For example, an automation could respond to a person being in one defined area rather than anywhere within the sensor’s field. Matter support and local-control options may appeal to households that want to connect devices across smart-home platforms or limit reliance on cloud services. Actual compatibility and performance can depend on the user’s platform, placement and setup.

Shelly Enters mmWave Sensing
The Presence Gen4 is Shelly’s first mmWave sensor, according to the source report. The product combines radar-based presence detection with other radios and Matter support, positioning it as both a sensor and a trigger for connected-device automations. Matter is intended to help compatible smart-home products work across participating platforms, though specific features can vary by ecosystem.
Shelly says the sensor includes minimum- and maximum-height settings, which users can adjust to include or filter out pets, robot cleaners and other small objects. It also has a light sensor for detecting changes in ambient lighting. These functions add configuration options, but the source material does not provide independent test results or detailed guidance on how consistently the device distinguishes people from pets or other moving objects.
“Accurate presence detection unlocks the kind of smart home experience customers have long dreamed about, where everything from lighting to HVAC respond automatically without needing to lift a finger.”
— Matt Brown, CMO of Shelly USA
Performance Claims Await Testing
The source report describes the sensor’s capabilities but provides no independent test results confirming how accurately it tracks 10 people at once, separates occupancy across 10 zones or performs across the stated coverage areas. It is also unclear how well the height filters distinguish pets and small devices in varied home environments, or how placement and room layout affect detection.
The report says the product is available through Shelly and refers to Amazon availability, but does not give a separate Amazon launch date. It also does not detail whether every listed platform supports all of the sensor’s zone-level features through Matter. Buyers may need to check the capabilities of their particular smart-home system before relying on a specific automation.
Availability and User Testing
The Presence Gen4 is listed as available now in North America at a suggested retail price of $84.99. The next useful evidence will come from hands-on testing of its tracking accuracy, zone setup, detection range and integration with individual Matter platforms. Shelly’s product information and app configuration should clarify supported settings as customers begin installing the sensor.
For prospective buyers, the practical next step is to confirm that their hub or smart-home platform supports the functions they want, then assess whether the sensor can be placed within its stated field of view and near a USB-C power source. Broader availability and independent evaluations are not specified in the source material.
Key Questions
What is the Shelly Presence Gen4?
It is Shelly’s first mmWave radar presence sensor, designed to detect occupancy and trigger smart-home automations. It supports Matter as well as Wi-Fi, Bluetooth and Zigbee.
How many people and zones can it track?
Shelly says the sensor can detect up to 10 people across up to 10 customizable zones. Independent verification of that stated capacity is not included in the source report.
How much does the Presence Gen4 cost?
The reported suggested retail price is $84.99. It is listed as available through Shelly’s North American store; the source also refers to Amazon availability.
Does the sensor require cloud access?
The source report says the Presence Gen4 offers a cloud-free local-control option, as well as custom scripting. Buyers should check which functions their chosen smart-home platform supports locally.
Can it detect pets?
Shelly says the sensor has minimum- and maximum-height settings that can be adjusted to include or filter out pets and small objects. The source does not provide independent accuracy tests for those filters.
