Shelly BLU Motion ZB – Smart Motion and Light Sensor, Zigbee 3.0 Protocol, Battery Life of up to 5 Years, Universal Compatibility

The Shelly BLU Motion ZB expands the Shelly ecosystem into the Zigbee 3.0 connectivity space, serving as an ultra-compact and highly energy-efficient motion and light sensor (lux meter). Designed to ensure instant detection and adjustable sensitivity, this sensor is the ideal component for presence-based automation. Thanks to the Zigbee protocol, energy consumption is kept to a minimum, offering a remarkable battery life of up to 5 years, whilst its extensive compatibility allows it to integrate natively with both Zigbee-compatible hubs from the Shelly range and universal open-source controllers.

Key Features & Technical Advantages

• Zigbee 3.0 Protocol (Efficiency and Stability): Unlike traditional Wi-Fi sensors, the Zigbee (ZB) communicates via a mesh network, offering minimal response times and excellent signal stability, whilst relieving the Wi-Fi router of additional connections.

• Dual Sensor (Motion + Light Sensor): As well as detecting human presence, the device continuously measures ambient light levels in lux. This enables smart calibration of scenarios (e.g. the light switches on in response to movement only if the room is dark enough).

• Record Battery Life of up to 5 Years: Thanks to rigorous optimisation of the Zigbee protocol and next-generation hardware components, the included CR2477 battery offers an extremely long lifespan, eliminating the need for regular maintenance.

• Adjustable Sensitivity and Range: The sensor offers maximum flexibility in configuration, allowing you to adjust motion sensitivity (across multiple levels) to avoid false alarms caused by small pets or draughts.

• Universal Open-Source Compatibility: As well as integrating with Zigbee-compatible Shelly gateways, the sensor adheres to the protocol’s strict standards, making it 100% compatible with Home Assistant (via Zigbee2MQTT or ZHA), Hubitat, SmartThings and other Zigbee hubs on the market.

• Minimalist Design and Flexible Installation: Its compact size and matt finish allow it to blend in unnoticed in any corner of the room. The pack includes an adhesive mount and a swivel joint for perfect adjustment of the detection angle.

Examples of Applications and Automations

1. Smart Lighting in Hallways and Stairwells: Instantly switch on the lights in your home (by controlling a Shelly Plus 1 or Plus 2PM relay) when you step into the area, but only after sunset or if the blinds are down.

2. Home Security System: Send a critical notification to your phone or trigger a siren if movement is detected in the home during the time when the system is armed and everyone is out.

3. Energy Saving in Offices: Automatically switches off the air conditioning or lights in a room if the sensor detects no human presence for 15–20 minutes, reducing utility bills.
