Shelly Presence Gen4
Device identification Device name: Shelly Presence Gen4 Device model: S4SN-0U61X Device SSID: ShellyPresence-XXXXXXXXXXXX BLE ID: 0x1821 Short description Shelly Presence Gen4 is a presence sensor that uses mmWave radar to reliably detect people, even when they are sitting still. It enables more natural room automation by sensing actual presence rather than just motion. It is designed for precise, room-aware automations with customizable detection behavior for both real rooms and open spaces. With up to 10 customized zones, you can tailor how the sensor reacts in different areas and fine-tune it to match your layout. Shelly Presence Gen4 connects via Wi-Fi 6, Bluetooth 5 LE, and Zigbee 3.0, and it supports Matter-over-Wi-Fi. It integrates with Shelly Cloud, Home Assistant, and other popular platforms. You can also manage and monitor it through its own Embedded Web interface. Main features Identifies up to 6 separate people simultaneously for realistic multi-occupant automations Supports up to 10 customized detection zones for more precise, area-specific automations Covers up to 42 m² to handle larger rooms and open areas Visualizes detected people on a map for clear, real-time understanding of the space Allows configurable transmission power and sensitivity, including advanced fine-tuning controls Provides filtering options to ignore near-ground movement and to avoid detecting small objects such as pets or robot vacuum cleaners Built-in light sensor that reports dark, twilight, and bright states for lighting-aware automations Operates via USB‑C (5 V) for continuous power Connects via Wi-Fi 6, Bluetooth 5 LE, and Zigbee 3.0, with Matter-over-Wi-Fi support Integrates with Shelly Cloud, Home Assistant, and other popular platforms Built-in Embedded Web interface for direct device access and configuration Use cases Hands-Free Room Automation Enter a room and let Shelly Presence Gen4 instantly trigger the lights, AC, or music - no need for switches or voice commands. Zone-Based Smart Lighting Use multi-zone detection to light only the areas in use - perfect for large rooms, studios, or open-plan homes. Energy Efficiency in Empty Spaces Automatically turn off appliances and lights when no one is present, helping reduce energy costs and waste. Ambient Light-Aware Scenes Trigger different scenes based on light levels - like activating soft lighting during twilight or full brightness when it’s dark. True Presence Detection in Quiet Settings Ideal for bedrooms, offices, or meeting rooms where people remain still - detects presence even without motion. Privacy-Friendly Occupancy Awareness Monitor when and where people are present without using cameras - ideal for sensitive spaces like restrooms, bedrooms, or offices. Pet-Friendly Setup Avoid false triggers from pets or robot vacuums by adjusting the detection sensitivity to match only human movement.

It comes pre-attached to a free-standing base with a built-in metal weight for added stability. The following mounting methods are recommended: With screws and wall plugs Detach the mounting plate from the free-standing base by removing the two screws with a Phillips screwdriver. Hold the mounting plate against the wall and mark the hole positions with a pencil. Drill holes at the marked positions. Insert the wall plugs and fix the mounting plate using the provided screws. With adhesive tape Detach the mounting plate from the free-standing base by removing the two screws with a Phillips screwdriver. Clean and dry the mounting surface. Attach the double-sided adhesive tape to the back of the mounting plate. Press the plate firmly against the surface for a few seconds. Flipped mounting Flipped mounting adjusts the detection logic when you rotate the Device 180°. Use this feature when you mount the Device upside down to match the room layout or mounting height. This improves presence detection in specific installation setups. To activate it, enable Flipped mounting in the Device’s web interface or in the Shelly Smart Control app. Detach the mounting plate from the free-standing base by removing the two screws with a Phillips screwdriver. Rotate the Device 180°. Reattach the mounting plate to the free-standing base and fix it with the two screws. Placement and range Shelly Presence Gen4 is intended for indoor use in spaces with maximum dimensions of 8 × 8 m (26 × 26 ft). Detection coverage may vary depending on the sensor’s horizontal and vertical placement within the room, as well as its tilt angle. The optimal installation height is 2 m (6.5 ft), with a maximum supported room height of 5 m (16.4 ft). The recommended tilt angle is approximately 15°. The following placement configurations are advised: On a wall Position the sensor preferably at the horizontal center of a wall to ensure it utilizes its full 140‑degree detection field. The Device can be secured using the adhesive tape or mounted with the screws. On a horizontal surface When using the device with its free-standing base, it may be positioned on furniture of sufficient height to ensure proper operational coverage. A flipped mounting setup works well for this application. In a corner (left or right) Use this configuration for smaller spaces, as this placement limits the detection field to 7 × 7 m (23 × 23 ft) and reduces the detection range to 90°. The recommended placement angle is 45° of the sensor center relative to each wall. The device cannot detect objects situated behind walls or other solid obstructions, even when these objects lie within its nominal detection range. The detection sensor is located on the front of the device and is unable to register movement occurring behind it. In case the device is mounted above the recommended height, adjust the tilt angle to maintain proper detection coverage. When mounted, specify the chosen device position in its web interface or Shelly Smart Control app to optimize detection coverage. Matter If you use the device with a Matter-compatible home automation system, only one room zone will be visible in its interface by default. You can have up to a maximum of ten zones. Each newly added zone will appear as a separate component.
