Shelly BLU Motion ZB

Shelly BLU Motion ZB Zigbee Motion & Light Sensor

Make lighting and smart-home automations respond to movement and actual room brightness with the Shelly BLU Motion ZB. This compact, battery-powered Zigbee motion sensor combines PIR motion detection with ambient light measurement, helping you create more responsive and energy-efficient automations without running wires.

Adjustable motion sensitivity and configurable brightness levels let you determine precisely when an automation should activate. Install it in minutes using the included double-sided adhesive and enjoy up to five years of operation from the included CR2477 battery.

• Secure communication: Supports AES encryption using CCM mode.

Smarter Motion-Based Automation

The Shelly BLU Motion ZB detects movement and reports the surrounding brightness level, allowing your automations to consider both occupancy and available light.

Instead of turning lights on whenever movement occurs, you can configure your system to activate them only when the space is dark or dim. This provides convenient hands-free lighting while reducing unnecessary energy consumption.

Popular Uses

Hallway and Stairway Lighting

Automatically turn on lights when someone enters a hallway or stairway, but only when the ambient light level is low. This provides safer navigation at night without wasting energy during daylight hours.

Living Room Scenes

Combine motion detection with the configurable Twilight level to activate evening scenes when the room is occupied and naturally dim. Compatible lights, blinds and other smart devices can respond automatically.

Home Office Automation

Turn on lights or connected equipment when movement is detected and the room is not already sufficiently bright. Your automation platform can switch devices off again after a chosen period without motion.

Entryway Awareness

Trigger lighting or notifications when movement is detected near an entrance. Adjustable sensitivity can help reduce unwanted triggers from distant movement or smaller pets.

Energy-Efficient Lighting

Use motion and brightness data together so lights operate only when a room is occupied and additional illumination is genuinely needed.

Dark, Twilight and Bright Levels

The integrated lux sensor supports three configurable ambient-light states:

• Dark: Suitable for night-time lighting and low-light security automations.
• Twilight: Ideal for evening scenes and comfort lighting.
• Bright: Helps prevent lights from turning on when sufficient natural or artificial light is already available.

The thresholds between these levels can be adjusted to suit the room and your preferred automation behaviour.

Dual Wireless Connectivity

Zigbee

Connect the sensor to a compatible Zigbee hub or coordinator for responsive motion and brightness automations. Zigbee provides low-power operation and reliable communication within an established mesh network.

Bluetooth and BTHome

Bluetooth 5 LE and BTHome support provide additional integration options with compatible Shelly devices and smart-home platforms. Zigbee and Bluetooth can operate simultaneously for flexible system design.

Button Controls

• Press four times quickly: Activates Bluetooth pairing mode. The LED flashes blue for one minute.
• Press five times quickly: Activates Zigbee pairing mode. The LED flashes purple for one minute.
• Press and hold for 30 seconds: Restores factory settings. The LED flashes red for two seconds before the device restarts.

LED Indication

The device flashes red whenever motion is detected and broadcast. This motion-indication flash can be disabled through the Shelly app if discreet operation is preferred.

Compatible Shelly Devices

• Shelly Plus series
• Shelly Gen3 series
• Shelly Gen4 series
• Shelly Pro series

Available features and integration methods depend on the selected Zigbee hub, Bluetooth gateway and smart-home platform.
