Product detailed description

📡 Sensor for perfect presence detection and smart automation 

Thanks to advanced radar technology, it can detect even the slightest human presence – whether someone is actively moving or just sitting still. The sensor can track up to 6 people simultaneously and supports up to 10 separate detection zones , making it ideal for smart automation in larger or open spaces. 

Thanks to adjustable sensitivity, false triggers caused by pets or robot vacuums can be effectively filtered out. It is the ideal upgrade for lighting, heating and air conditioning (HVAC) systems, and energy-saving scenarios. The sensor is extremely compact, easily placed anywhere, and guarantees perfect control, comfort, and maximum efficiency.

The device features Wi-Fi connection (for direct connection), Zigbee (for a stable mesh network), and Bluetooth (for easy pairing and local use), and is also compatible with the Matter standard, ensuring broad integration into various smart home systems.

Its compact design and flexible placement options allow for easy installation on walls, shelves, or even furniture.More demanding users can rely on MQTT protocol support and seamless connection with voice assistants such as Alexa.

The sensor allows you to create a wide range of automation scenarios – for example, turning on lights when someone enters a 3-meter radius, or triggering ventilation. Whatever your requirements, the Shelly Presence Gen4 sensor makes them easy to achieve.

Solutions

💡 Zone lighting

With 10 detection zones, the sensor activates light only where people are present. Ideal for large rooms – you only light up where you need it, and automatically save everywhere else.

⚡ Energy saving

When the sensor detects that a room is empty, it automatically turns off lights, AC, and appliances. At home and in the office, you can easily lower your energy bills and end waste for good.

🧍 Presence detection  

Where standard motion sensors fail, the advanced Shelly radar steps in. It detects presence even without the slightest movement and without cameras – whether you are sleeping, reading, or working in your home office. 

🛡️ Security

Shelly Presence Gen4 reacts to real presence, not just basic motion, taking security to the next level. At home or away, you are assured of accurate monitoring and maximum peace of mind.
