The Bosch Door/Window Contact II is a wireless sensor designed for monitoring doors and windows. It features ZigBee connectivity, a compact size of 22x23x75 mm, and a long battery life of up to 60 months using a CR123A lithium battery.

## Long description

The Bosch Door/Window Contact II is a compact wireless ZigBee sensor for monitoring doors, windows and other closable openings. Available in a standard model and a Plus version with an additional vibration sensor, the device reports open/closed status to the Bosch Smart Home system and supports energy-saving and security functions such as automatic radiator setback during ventilation and alarm triggering when openings are opened or vibrated.
Advantages
The sensor offers a small, waterproof design and long battery life with a CR123A lithium cell. It provides reliable open/closed detection and, in the Plus version, vibration detection with adjustable sensitivity. Integration with the Bosch Smart Home controller enables push notifications, widgets, voice queries via Amazon Alexa or Google Assistant, and coordinated services like break-in protection and sustainable ventilation. Installation is simple using the supplied adhesive strips and a discreet 3 mm magnet for many window types.
Suitable for
Doors and windows
Garage doors, summer houses and garden gates
Cabinets: medicine cabinet, cleaning cupboard, pantry
Letterboxes and pet flaps
Any other opening where you need to monitor open/closed status

Connectivity: ZigBee
Dimensions: 22 x 23 x 75 mm
Battery: CR123A lithium battery (up to 60 months battery life)

MPN: 8750002090

How to use
Mount the sensor and magnet on the door or window using the adhesive strips or screws where appropriate, ensuring correct alignment so the sensor detects open and closed states. Pair the sensor with the Bosch Smart Home controller via ZigBee and configure the device in the Bosch Smart Home app. Choose whether you want push notifications or widgets to receive status updates, and use voice assistants to query window and door status if desired.
Usage recommendations
Use the Plus version if you require early break-in detection via vibration sensing and set the vibration sensitivity to one of five levels according to the installation location. Enable the “Sustainable ventilation” service to reduce radiator heat automatically when windows are open, and use the sensor button double-press to temporarily pause automations when you need to open an entry without triggering alarms.
