Zigbee Gosund ST18 smart door and window opening sensor
The Gosund ST18 is an advanced door and window opening sensor that gives you full control over the security of your home. Thanks to its integration with a mobile app, you receive instant push notifications about any activity related to opening or closing doors and windows, allowing you to monitor the situation at home in real time. The product requires a ZigBee gateway (not included) for proper operation.
Instant notifications
The Gosund ST18 sensor sends instant notifications to the user's smartphone when it detects the opening or closing of a door or window. This way you are always up to date with what is happening in your home, even when you are away. Such functionality increases security and allows you to react quickly to unwanted events.
Easy installation and configuration
The Gosund ST18 is easy to install and requires no complicated installation. Just place the sensor on the door or window, making sure that the gap between the sensor and the magnet is less than 10 mm. The compact size (71x25x20 mm) and lightweight design (53 g) allow the device to be mounted discreetly without affecting the aesthetics of the interior.
Share the device with your family
With the Smart Life mobile app, you can easily share the sensor with other family members, which also allows them to receive notifications and monitor the status of doors and windows. This way, each family member is informed of important events, increasing the overall security of the home.
Automation of lights
The Gosund ST18 sensor can be integrated with other smart devices in the home to create automation scenarios. For example, opening a door can automatically turn on the lights in a room, increasing convenience and saving energy.
Long operating time
The device is powered by two AAA batteries (LR03-1.5V), which provide a long operating time of up to 16 months. The sensor is also equipped with a low-battery function, allowing you to change the batteries in time to avoid interruptions in operation.
