Motion detection for home automation

The Shelly Blu Motion is a Bluetooth motion sensor with an integrated lux sensor designed for home security and automation. It detects movement and ambient light levels to trigger connected devices or send alerts. The unit runs on a long-lasting battery and requires a Shelly Bluetooth gateway or compatible Plus-series device to operate within a smart-home system.

Behaviour under continuous monitoring

The sensor provides real-time motion detection with a quick response time and maintains operation through its long-lasting battery during extended use. It covers a 120-degree detection angle and identifies movement up to 30 feet, allowing it to monitor large rooms or hallways without gaps. Customisable alarm zones let users focus on critical areas while ignoring routine activity.

Limits of the Bluetooth interface

Communication relies on Bluetooth, so the sensor must remain within range of a supported gateway to relay events to the cloud or app. The 30-foot detection range applies to motion sensing, not to the wireless link, which can be affected by walls and interference. Users needing coverage beyond a single gateway’s reach must add additional gateways or use compatible Shelly Plus devices as repeaters.

Questions about this item

How much power does the Bluetooth radio draw when the sensor runs all day?

The sensor uses a long-lasting battery designed for continuous performance, so daily power draw stays very low.

Which gateway must I already own for the sensor to work?

A Shelly Bluetooth Gateway is required, or any Shelly Plus series device that can act as a gateway.

Will the 120-degree detection angle still cover the hallway if I keep my older Shelly relays?

Yes, the 120-degree field and 30-foot range work alongside existing Shelly relays through the same gateway.
