Bosch Door/Window Contact II Plus Wireless Door/Window Sensor White

The Bosch Door/Window Contact II Plus is a compact, wireless sensor designed to monitor the status of doors and windows within your smart home ecosystem. Featuring advanced ZigBee connectivity, this device provides real-time updates on whether your entry points are open or closed. The Plus version includes an integrated vibration sensor, offering an additional layer of security by detecting tampering or break-in attempts before a window is even opened. With its sleek white finish and unobtrusive design, it integrates seamlessly into any home interior while providing reliable performance for up to 36 months on a single battery.

Advantages

This sensor offers a comprehensive approach to home management by combining security and energy efficiency. By integrating with your smart heating system, it automatically lowers radiator thermostats when a window is opened, preventing unnecessary heat loss and reducing energy costs. The inclusion of a vibration sensor allows for proactive security, triggering alarms at the first sign of forced entry. Users benefit from instant push notifications and voice assistant compatibility, ensuring complete peace of mind whether at home or away. The device is highly versatile, featuring a physical button that can be used to pause monitoring for ventilation or to trigger custom smart home scenarios.
