Short description
Shelly BLU Motion ZB(the Device) is a compact, battery-powered motion sensor designed to bring smart automation to any space without wiring or drilling. It detects movement and ambient brightness in one device, making it ideal for automating lights, scenes, and notifications based on real activity and actual room conditions.
With dual wireless connectivity, BLU Motion ZB combines flexible Zigbee-based smart home integration with low-energy Bluetooth capabilities for advanced presence and automation scenarios. Adjustable motion sensitivity and configurable light thresholds help you fine-tune when and how your automations trigger, while the long-life CR2477 battery keeps it running reliably for extended periods.
Main features
Battery-powered by a single CR2477 cell, providing long, maintenance-friendly operation without wiring
Integrated motion detection with adjustable sensitivity, so you can tailor responsiveness for hallways, living rooms, or quieter areas
Built-in lux sensor with three configurable levels (dark, twilight, bright), including customizable thresholds between levels for precise light-based automations
Easy, tool-free installation using the included double-sided adhesive, allowing you to place the sensor exactly where it’s needed
Zigbee 3.0 and Bluetooth 5 LE, supporting simultaneous Zigbee + Bluetooth operation for flexible system design
Supports BTHome, enabling straightforward data integration into Shelly and compatible smart home platforms
Use cases
Install BLU Motion ZB in a hallway to automatically switch on lights only when someone passes by and the lux sensor reports low ambient light. This reduces energy usage by avoiding unnecessary lighting during the day while ensuring safe, hands-free navigation at night.
Place the sensor in a living room and combine motion detection with the adjustable twilight level to trigger cozy evening scenes. Lights, blinds, or other Zigbee-connected devices can respond only when the room is both occupied and naturally dim, keeping the environment comfortable and efficient.
Use BLU Motion ZB in a home office to turn lights and related equipment on when motion is detected and sufficient brightness isn’t already present. When no motion is registered for a set period, your Zigbee automation can switch everything off, helping to cut standby consumption.
Mount the sensor near an entryway to act as a subtle security and awareness device, triggering notifications or lighting when unexpected motion is detected in darker conditions. With sensitivity adjustment, you can reduce false triggers from pets or distant movement.

Solutions
Shelly BLU Motion ZB
Hallway Motion Lighting
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
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
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
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.
