Sensor & Alert Systems
The Shelly Presence Gen4 is an advanced smart presence sensor that combines high-precision mmWave presence detection with motion sensing to deliver intelligent occupancy detection for modern smart homes. Supporting Wi-Fi, Zigbee, Bluetooth, and Matter, it enables highly responsive automation based on real human presence rather than simple movement.
Unlike traditional PIR motion sensors, the Shelly Presence Gen4 can detect occupants even when they remain still, making it ideal for lighting control, climate automation, security, and energy-saving smart home scenarios.
The integrated mmWave presence sensor continuously detects human presence with exceptional accuracy, even when someone is sitting, reading, sleeping, or working without noticeable movement. This creates more reliable automations and eliminates the limitations of conventional motion sensors.
The Shelly Presence Gen4 automatically controls lighting, heating, cooling, and ventilation based on room occupancy. Turn lights on when someone enters a room and switch them off only after the room is truly empty, improving comfort while reducing unnecessary energy consumption.
Create intelligent automations that adapt your home to your daily routine without requiring manual interaction.
The smart presence sensor supports multiple communication protocols, making it easy to integrate into virtually any smart home ecosystem.
The Shelly Presence Gen4 works seamlessly with Shelly Smart Control, Home Assistant, Google Home, Amazon Alexa, SmartThings, and other Matter-compatible smart home platforms.
Build intelligent automations using occupancy detection, schedules, scripting, MQTT, webhooks, and local logic. Automatically activate lighting, adjust heating or air conditioning, control motorized blinds, arm security systems, or trigger custom scenes whenever someone enters or leaves a room.
Local scripting ensures your automations continue working reliably even without internet access.
The room occupancy sensor helps eliminate wasted electricity by ensuring lighting and climate systems only operate when rooms are actually occupied. This improves user comfort while reducing energy consumption across residential and commercial buildings.
The Shelly Presence Gen4 is a smart presence sensor that uses advanced mmWave presence detection to detect human occupancy with much greater accuracy than traditional motion sensors.
A traditional motion sensor only detects movement. The Shelly Presence Gen4 can detect people even when they remain still, making automations significantly more reliable.
Yes. It supports Matter together with Wi-Fi, Zigbee 3.0, and Bluetooth for maximum compatibility with modern smart home ecosystems.
You can automate lighting, heating, cooling, ventilation, security systems, blinds, and custom smart home scenes based on real-time room occupancy.
The Shelly Presence Gen4 combines precise mmWave presence detection, intelligent occupancy sensing, and flexible Wi-Fi, Zigbee, and Matter connectivity in one powerful smart presence sensor. Whether you're creating a more comfortable home, reducing energy consumption, or building advanced smart home automations, it delivers reliable presence detection that responds to people—not just movement.
