BOSCH - Smart Home Door/Window Contact II Zigbee, gray (IP45)

A perfect overview:

No need to scour the whole house: with your door/window contact (plus), you can see at a glance in the app whether a window or door is open or closed. If the status of a door or window changes, you can be informed via a push notification or widget, whether you're at home or out and about.

Optimum intruder protection:

When your door/window contact (plus) detects the opening of a window, if your alarm system is activated, it immediately triggers an alarm. The plus version of the security system's door/window contact even triggers an intruder alarm as soon as a shock is detected. Even smarter: as soon as the alarm system is activated, you'll be informed of any security breaches associated with open doors/windows.

Simple durability:

Your door/window contact (plus) makes it easy to save energy, thanks to the "Sustainable ventilation" service: when the intelligent window sensor detects the opening of a window for ventilation, the room's intelligent thermostats automatically lower the temperature. So you don't heat up the outside.

Versatile use:

You choose what qualifies as a door or window:

your Bosch Smart Home door/window contact (plus) is small, compact and waterproof. It can be used anywhere you want to know if something is open or closed:

• Doors and windows Garage doors
• Garden sheds and gates
• Medicine cabinet
• Cleaning cupboard, pantry
• Mailboxes
• Mailboxes

And much, much more! Let your imagination run wild. Thanks to this versatile little device, you'll be informed of every opening and closing in your home.

Sustainable ventilation: heating while saving energy

Don't feel like heating the outside? When the door/window contact (plus) detects an open window, it can automatically lower the room's radiator thermostat. This saves you heating and energy costs, without any effort on your part.

Use the button to pause the sensor or as a control element

The button on the intelligent window sensor is just as versatile as the door/window contact (plus) : A double-click activates the pause function. This lets you open and close doors/windows once, without activating services or automations. Very practical, for example to air out or let the dog out without triggering the alarm.
