Short description

Shelly BLU Door/Window Outdoor ZB (the Device) is a rugged outdoor door/window sensor for reliable door and window monitoring. With an IP55 enclosure, it’s designed to keep working in exposed locations like gates, sheds, and outdoor entrances. Beyond simple open/close detection, it enables richer automations by tracking door/window tilt (inclination angle). Dual connectivity via Zigbee 3.0 and Bluetooth 5 LE - capable of simultaneous operation - helps you fit it into different smart home setups and workflows.

Main features

Zigbee 3.0 and Bluetooth 5 LE connectivity, with support for simultaneous Zigbee + Bluetooth operation
Supports BTHome for compatible Bluetooth-based automations and integrations
Long battery life for low-maintenance operation
Door/window inclination angle measurement for detecting tilt/vent positions, not just open/close
Encrypted mode for protected communication

Use cases

When a door is opened during your “away” schedule, the sensor’s open/close detection can trigger an automation to turn on exterior lights and send an alert. This helps you react quickly to unexpected entry while keeping the automation simple and reliable.
When a window is tilted the inclination angle measurement can trigger a “ventilation mode” routine instead of treating it like a fully open window. This lets you reduce unnecessary alarms and apply different comfort rules for fresh-air positions.
When a window is opened a routine can be triggered to close the TRV or stop the AC until the window is closed.
Stick the sensor on a walk-in closet or pantry door. The light turns on the moment the door is cracked open and shuts off immediately when closed, ensuring the light is never accidentally left on all night.
If the contact sensor remains open for more than 5 minutes, your smart speaker can play a chime or your hallway light can flash red. This is perfect for ensuring the door to the garage or backyard isn't left wide open by kids or pets.
If a window stays tilted beyond a set time limit, the reported inclination angle can trigger an automation that reminds you to close it before bedtime. This reduces heat loss and improves peace of mind without requiring you to check every window manually.
In a high-traffic entry area, the long battery life supports frequent open/close events while still keeping maintenance low. You can use those events to automatically start a hallway lighting scene when the door opens and stop it a few minutes after it closes, improving convenience and saving energy.

Why Shelly BLU Door/Window Outdoor ZB

Built for Outside. Smart Enough for Everything Else.

Most door and window sensors stop at open or close. This one also tracks the angle - so you know whether a window is cracked, half-open, or fully ajar. Its IP55-rated shell handles frost, humidity, and summer heat without missing a beat. With both Zigbee and Bluetooth on board, it fits into virtually any smart home setup. Mount it on a gate, shed, or exterior entrance in minutes, and let it run for up to 5 years on a single battery.

Tilt & Angle Detection

Measures inclination angle to track ventilation positions and partial openings - not just whether a door or window is open or closed.

Instant Status Broadcasting

Sends open/close and tilt updates over Zigbee or Bluetooth the moment a change is detected, triggering automations without delay.

Beacon Mode

Broadcasts status periodically for setups that need regular state updates rather than event-driven triggers only.

AES Encrypted Transmission

All wireless communication uses AES encryption to keep status data secure between the sensor and your gateway or hub.

Shelly Smart Control App

View sensor status, monitor battery level, and configure settings including Beacon mode and pairing directly from the app.

Adhesive Mount Installation

Attaches to fixed frames using included double-sided foam pads - no screws, no drilling, works on gates, sheds, and exterior frames.

Solutions

Shelly BLU Door/Window Outdoor ZB

Garage Door Reminder

Never leave the garage open by mistake again. Set an automation to flash lights or trigger a chime if the garage door stays open for more than five minutes - useful when kids or pets are nearby and a quick visual check isn't enough.

Multi-Gate Management

Monitor multiple entry points across an apartment complex, retail site, or gated property from one place. Get instant alerts when any gate opens or closes, and keep a clear picture of who has access and when - without checking each point manually.

Greenhouse Heat Prevention

Use inclination angle detection to monitor tilted windows in a greenhouse or conservatory. Set a reminder to close them before nightfall to prevent heat loss overnight - a simple automation that protects plants without any manual monitoring.

Remote Gate Monitoring

Check whether your backyard gate, garden entrance, or outbuilding door is open or closed from anywhere via the app. Get peace of mind while away from home without needing a camera or additional security hardware.

Shed Entry Lighting

Automate your shed or outbuilding lights to switch on the moment the door opens at night. No fumbling for switches in the dark - the sensor detects the opening and triggers the light instantly.
