The Shelly Presence Gen4 is an advanced presence sensor from the manufacturer, utilizing mmWave radar technology (60–64 GHz) for precise and reliable detection. Unlike traditional motion sensors, it detects not only movement but actual presence, meaning it continues to work even when someone is sitting still or remaining stationary in a room.
The sensor can track up to 6 people simultaneously and supports up to 10 separate detection zones, making it ideal for intelligent automation in larger or open spaces. With adjustable sensitivity, false triggers caused by pets or robot vacuums can be effectively filtered out.
The device features Wi-Fi, Zigbee, and Bluetooth connectivity, and is also Matter-compatible, ensuring broad integration with various smart home systems. Its compact design and flexible placement options allow for easy installation on walls, shelves, or even furniture. It enables the creation of a wide range of automation scenarios, such as turning on lights when someone enters within a 3-meter range or starting ventilation. Whatever your needs, they can be easily implemented with the Shelly Presence Gen4 sensor.
