SwitchBot contact sensor for opening windows/doors

The SwitchBot contact sensor is an innovative component of a smart home system that provides security and convenience by monitoring doors and windows. After integration with the SwitchBot application, you can receive notifications of registered events directly to your smartphone, allowing you to control your home from anywhere and at any time. The device is installed efficiently and without any hassle, and compatibility with popular voice assistants improves usability.

Entry and exit control

With the SwitchBot sensor, you can accurately monitor movement around your front and interior doors. The device detects when residents leave the house and when they approach, and allows you to automatically turn on or off electrical appliances based on their presence. The detection range is up to 5 meters (90° horizontally and 55° vertically). This optimizes energy consumption and increases security by alerting you to unexpected entrances or exits - including unwanted individuals.

More with the app

When connected to the SwitchBot app and SwitchBot Hub Mini, you will receive notifications on your smartphone for any event, such as opening windows or doors. The ability to check the status of your home from anywhere provides control and peace of mind, especially for families with children or pets.

Voice control

When configured with the SwitchBot Hub, the Mini Sensor offers integration with various external services. This allows you to control it with your voice and remotely via your smart speaker and smartphone. Voice assistants like Alexa or Google Home notify you of any door or window opening, and additional features like light and motion sensors are available via IFTTT.

Automation for your comfort

The contact sensor can be configured to work with other SwitchBot devices to create automation scenarios – such as closing window shades or turning on lights when a door is detected open. This intelligent solution adapts the environment to your needs and not only increases comfort but also improves the energy efficiency of your home.

Universal use

Easy to install and use, the contact sensor can be easily mounted on any type of door or window. Its versatility allows it to be placed in various areas of the home – from the main entrance, through room doors, to balcony windows, cabinets with important documents or even pet cages.

Durable and reliable

The sensor requires 2 AAA batteries for power, which provide up to 3 years of operation. In addition, its resistance to a wide temperature range (from -10°C to 60°C) ensures the reliability of the device in almost all conditions.

Included in the package:

• Window/door opening sensor

• Screw set

Same summary

The SwitchBot contact sensor is designed for those who want simple and clear control over the opening of doors or windows in their home. It is especially suitable for users who already use the SwitchBot ecosystem and is not an obstacle for them that it requires an appropriate control panel to operate. Since the device does not support WiFi connection, it is mainly suitable for those for whom the stability of the local network and central management mean more than simple independent use. When choosing, it is important to consider that without a control panel, the sensor does not perform all smart functions - therefore it is best supplemented in larger or modularly designed smart home systems.
