Shelly Launches Presence Gen4 in North America: Intelligent Occupancy Detection for Home Automation

Boca Raton, FL — October 15, 2026 — Shelly Group, a global leader in smart home automation, today launched the Shelly Presence Gen4 in North America, a next-generation radar sensor built to solve one of smart home's oldest challenges: accurately detecting where people are located in a home. Shelly Presence Gen4 uses mmWave radar technology to reliably detect human presence and automate a wide range of helpful experiences and alerts without the need for indoor cameras. Shelly also offers a cloud-free local control option, which gives smart home users total control over their privacy and security.

Sensor Operation and Features

Shelly Presence Gen4 uses mmWave radar to detect the micro-movements of people, pets and objects, even when stationary or sitting still. This enables precise room automation by sensing actual presence rather than relying on basic motion detection. Designed to enable room-aware automations, Shelly Presence Gen4 empowers smart home users to automate lights, shades, climate, entertainment systems and more to respond to people based on where they are located in a room or home.

The sensor detects up to ten people simultaneously and supports up to ten independently customizable detection zones to trigger automations as people enter or leave specific areas in a room. Adjustable minimum and maximum height detection thresholds and other advanced settings allow customers to fine-tune sensor performance to filter out pets, robot vacuums, and other low-to-the-ground objects or restrict recognition to human-only movement. A real-time occupancy map shows exactly where people are detected in a space—without a camera ever capturing an image—making Presence Gen4 an ideal privacy-friendly alternative to video-based presence monitoring. A built-in ambient light sensor also reports dark, twilight, and bright conditions, enabling light-aware automations. New features and software improvements will also be released over time.

“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,” said Matt Brown, CMO, Shelly USA. “Shelly Presence Gen4 delivers unprecedented levels of control and adjustability with fine-tunable detection settings and pet-filtering options, which expands how users can automate their homes and improves reliability.”

Shelly Presence Gen4 Use Cases

• Hands-free room automation: Enter a room and let the sensor instantly trigger environmental settings such as lights, AC, or music without the need for switches or voice commands.
• Zone-based smart lighting: Leverage multi-zone detection to only light areas currently in use like desks, seating areas or entire rooms.
• Energy efficiency in empty spaces: Automatically turn off appliances or lights when no one is present, helping reduce energy costs.
• Ambient light-aware scenes: Trigger different automations based on light levels, like dim lights at dusk and full brightness after dark.
• Presence detection in seating areas: Ideal for bedrooms, home offices, living rooms and areas where people sit still for long stretches.
• Privacy-friendly occupancy awareness: Trigger presence-based automations without the use of cameras and without the need for a cloud/internet connection when using local control.
• Pet-friendly options: Choose to include small objects like pets in presence detection or adjust the sensitivity to filter out pets, robot vacuums and other low-to-the-ground objects.

Design, Specifications & Compatibility

Shelly Presence Gen4 is powered by USB-C for continuous operation and supports versatile installation options to suit any space. When wall-mounted, it covers a wide 140-degree horizontal field across spaces up to 650 square feet, ideally suited for larger rooms and open floor plans. When corner-mounted, it narrows to a 90-degree field covering up to 525 square feet, ideal for smaller or partitioned spaces. Tabletop and flat surface placement are also an option with a built-in stand.
