Enhanced Home Security & Automation
Install the Shelly BLU Door/Window on your front door, balconies, windows, or garage door to receive instant notifications when someone opens them while you're away. Create intelligent automation scenarios to turn off heating or air conditioning when windows are opened, or trigger lights when doors are accessed. The sensor's tilt angle measurement is ideal for tilt-and-turn windows, providing precise monitoring of window position.
Smart Ambient Light Monitoring
The integrated LUX sensor measures ambient light levels, enabling sophisticated lighting automation. Automatically adjust indoor lighting based on natural light entering through windows, or create scenes that respond to changes in outdoor lighting conditions throughout the day.
Two Operating Modes
Regular Mode: The sensor broadcasts open/closed state, illuminance, and battery status each time the state changes. For tilt-and-turn windows, it immediately reports the event, then broadcasts tilt angle data two seconds later, checking every 8 seconds for angle changes.
Beacon Mode: The sensor broadcasts current status, illuminance, and battery level every 30 seconds for continuous monitoring (note: this mode may reduce battery life).
Gateway Required
To use this device with the Shelly Smart Control app, a gateway is necessary. Compatible gateways include the Shelly BLU Gateway, or any Shelly Plus, Pro, or Gen3 device (excluding sensors). Use scripting functionalities on your Shelly Plus and Pro devices to create complex, customized automation scenarios.
