Shelly Presence Gen4 Know When Someone Is Really There

Upgrade your smart home with the Shelly Presence Gen4, an advanced 60–64 GHz mmWave human presence sensor designed to detect people accurately even when they are sitting completely still.

Unlike conventional PIR motion sensors that require noticeable movement, mmWave radar can identify subtle human presence such as someone working at a desk, reading, watching TV or resting on a couch.

The result is smarter, more reliable occupancy detection that can be used to control lighting, heating, air conditioning, ventilation and other smart home devices based on whether someone is actually in a room.

The Shelly Presence Gen4 can track up to 6 people simultaneously, divide an area into up to 10 custom detection zones, and provide a live visual representation of detected occupants.

Available in Black or White, it blends discreetly into modern homes, offices and commercial environments.

🧍 True Human Presence Detection

Traditional motion sensors can turn lights off simply because you’ve stopped moving.

The Shelly Presence Gen4 takes a different approach.

Its 60–64 GHz mmWave radar technology detects human presence and subtle movements, helping your automation system distinguish between an occupied room and an empty one.

This makes it ideal for situations such as:

• Someone sitting at a desk
• Reading in bed
• Watching television
• Working in an office
• Sitting in a meeting
• Resting on a sofa

Instead of asking “Did something move?”, your smart home can respond to “Is someone actually here?”

👥 Track Up to 6 People

The Presence Gen4 can detect and track up to six people simultaneously.

This opens up more advanced occupancy automations for shared spaces.

For example:

Living room:
Keep the lights and air conditioning active while people remain present.

Office:
Automatically manage lighting based on which areas are occupied.

Meeting room:
Turn equipment on when people arrive and off when the room becomes empty.

Open-plan areas:
Use different detection zones to trigger automations for specific areas.

📍 Create Up to 10 Detection Zones

Divide your detection area into up to 10 customisable zones and use them to create more precise automations.

Rather than treating an entire room as one detection area, you can create individual zones around furniture, workspaces or other areas.

This allows automations such as:

• Turn on a desk light when someone enters the workspace
• Control lighting only in occupied areas
• Detect whether a meeting table is occupied
• Ignore areas where movement isn’t relevant
• Trigger different scenes depending on where someone is detected

The live visualisation makes it easier to understand where detected people are located within the monitored area.

💡 Built-In Ambient Light Sensor

The Shelly Presence Gen4 also includes an integrated light sensor, providing information about the surrounding lighting conditions.

Combine presence detection with ambient light levels to create more intelligent lighting automations.

For example:

Someone enters + room is dark → turn lights on

Someone leaves + room is empty → turn lights off

Someone is present + sufficient daylight → keep lights off

This can improve both comfort and energy efficiency.

🐕 Smart Filtering for Pets & Robot Vacuums

Advanced detection and sensitivity settings help reduce unwanted triggers from pets and low-level movement, including robot vacuum cleaners.

This is particularly useful in homes where traditional motion sensors can be triggered by pets moving around the room.

🌐 Four Smart Home Protocols

One of the biggest advantages of the Shelly Presence Gen4 is its broad connectivity.

The sensor supports:

• Wi-Fi 6
• Zigbee 3.0
• Bluetooth 5 LE
• Matter over Wi-Fi

This gives you the flexibility to integrate the sensor into different smart home environments instead of being locked into a single ecosystem.

Good to know: The Shelly Presence Gen4 ships in Matter mode by default. Switching to Zigbee mode (via a simple button sequence) disables Matter. Wi-Fi and Bluetooth stay active either way.

---

🏠 Works with Home Assistant & Major Smart Home Platforms

The Presence Gen4 is an excellent choice for advanced local smart home installations.

It can integrate with platforms and ecosystems including:

• Home Assistant
• Apple Home
• Google Home
• Amazon Alexa
• Samsung SmartThings
• Shelly Smart Control
• Matter-compatible systems
• Compatible Zigbee platforms

For Home Assistant users, presence detection can become the foundation for highly responsive occupancy-based automations.

---

⚡ USB-C Powered

The Shelly Presence Gen4 uses 5V USB-C power, making installation straightforward and flexible.

It can be powered from a suitable USB-C power adapter or another appropriate 5V USB-C power source.

Because the sensor does not rely on batteries, it can continuously monitor the room without requiring regular battery replacement.

For reliable operation, use a high-quality 5V USB-C power supply.

---

🛠️ Flexible Installation

The compact Presence Gen4 can be installed in different ways depending on your environment.

Mounting options include:

• Freestanding placement
• Adhesive mounting
• Screw mounting

Its compact body measures approximately:

64 × 41 × 26 mm
(excluding the stand)

This makes it suitable for discreet placement on shelves, desks, walls and other convenient locations.

🧠 Powerful Local Automation

Shelly devices are particularly popular with smart home enthusiasts because they offer extensive local-control capabilities.

The Presence Gen4 supports advanced automation technologies including:

• Local web interface
• Webhooks
• MQTT
• Scripting
• Schedules
• Local actions
• Smart scenes

This makes it suitable for everything from simple “person detected → lights on” automations to sophisticated Home Assistant installations.
