## Description

The Shelly BLU Door/Window Outdoor ZB is a rugged, IP55-rated sensor engineered for gates, sheds, and exterior entrances. Featuring simultaneous Zigbee 3.0 and Bluetooth 5 LE connectivity, it detects open/close events and inclination angles to enable smart tilt automations, backed by encrypted communication and up to 5 years of battery life.

The Shelly BLU Door/Window Outdoor ZB is a weather-resistant contact and inclination sensor built for exposed installations. Protected by an IP55 enclosure and rated for operating temperatures from -20 °C to 40 °C, the unit withstands harsh environmental conditions when mounted to exterior gates, garage doors, outbuildings, or perimeter windows.
Beyond standard open and close status detection, the device integrates tilt measurement to track window and door inclination angles. This allows smart systems to distinguish between tilted ventilation positions and fully open entryways, triggering tailored actions such as setting TRVs to frost mode or sending notifications when windows remain tilted past a set threshold.
Equipped with dual Zigbee 3.0 and Bluetooth 5 LE radios, the sensor supports concurrent dual-protocol operation for flexible integration into diverse smart ecosystems. It natively supports BTHome protocols, encrypted communications, and pairs directly with Shelly Plus, Gen3, Gen4, and Pro gateway devices.
