## Description

The Shelly BLU Door/Window Outdoor ZB is a rugged IP55-rated sensor engineered for perimeter gates, sheds, and external entrances. Featuring simultaneous Zigbee 3.0 and Bluetooth 5 LE connectivity, it delivers instant open/close alerts and precise tilt-angle monitoring with an impressive battery life of up to 5 years.

The Shelly BLU Door/Window Outdoor ZB is a resilient smart contact sensor designed to withstand exposed environments such as garden gates, garages, sheds, and external entryways. Built with an IP55-rated weather-resistant enclosure, the sensor operates reliably in ambient temperatures ranging from -20 °C to 40 °C.
Equipped with dual-radio connectivity, the device supports simultaneous communication across Zigbee 3.0 and Bluetooth 5 LE. This allows seamless integration into existing Zigbee home automation networks while maintaining compatibility with Shelly Bluetooth ecosystems and third-party controllers via the BTHome protocol. Communication can also be secured using built-in encryption mode for enhanced transmission protection.
Beyond standard magnetic contact detection, the unit features an internal inclination sensor that measures opening tilt angles. This allows smart systems to distinguish between tilted ventilation positions and fully opened windows, enabling automated HVAC adjustments without triggering false intrusion alarms. Powered by a standard CR2032 coin cell, it delivers low-maintenance performance with up to 5 years of battery life.
