Features

Adjustable Motion Sensitivity

Fine-tune motion detection to match different spaces and reduce unwanted triggers from everyday movement.

BT Home Integration

Connect the sensor to compatible platforms using BTHome for flexible, cross-platform smart home setups.

Motion-Based Alerts

Receive notifications when movement is detected in selected areas, helping you stay informed in real time.

Scene Activation

Combine the sensor with your Shelly devices to create custom scenes (gateway required).

Scripting

Create custom automations using JavaScript to tailor system behavior to your needs (gateway required).

Secure Communication

Keep your data protected with AES encryption (CCM mode) for reliable and private communication between devices.

Use Cases

Hallway Motion Lighting

Dark hallways and transitional spaces become easier to move through when lighting adjusts automatically to movement around the home. Place Shelly BLU Motion ZB in a hallway and combine it with Shelly smart switches or bulbs in the Shelly Smart Control app to create scenes that softly illuminate the way as someone passes through. Whether heading to the kitchen late at night or moving between rooms without disturbing others, the space stays comfortable and easy to navigate.

Entryway Awareness

When movement is detected near entry areas in low-light conditions, your home can respond instantly. Place Shelly BLU Motion ZB near a front or back entrance and combine it with Shelly smart switches or bulbs in the Shelly Smart Control app to create scenes that react automatically. Whether arriving home late or checking activity around the house after dark, lighting and notifications help make entry spaces easier to monitor and navigate.

Garage Reminder

Movement around garages and backyard areas can easily go unnoticed after dark. Install Shelly BLU Motion ZB and combine it with Shelly smart switches, bulbs, and push notification in the Shelly Smart Control app to create automations that react when motion continues for an extended time in low-light conditions. This helps bring attention to spaces that may require a quick check before the house is closed up for the night.

Guided Night Lighting

Moving around your bedroom at night no longer means switching on harsh lights or searching for switches. Place the sensor on a nearby wall or bedside table to trigger soft lighting as soon as you get out of bed. Combined with Shelly smart switches or bulbs and set up in the Shelly Smart Control app, it creates a more comfortable nighttime atmosphere while keeping lighting gentle and unobtrusive.
