Instant Overview and Alerts for Security Breaches
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 allows you to keep a constant overview of the status of your doors and windows directly in the app. When a door or window is opened, the user receives an instant notification and can react according to the set smart home rules. The Tamper Detection feature also monitors for unauthorised handling or attempts to remove the device and sends an alert in the event of a breach. Combined with Zigbee 3.0, the sensor can be linked with other devices to create security scenes, such as activating an alarm, lighting, or camera recording.
Protection for More Than Just Doors and Windows
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 offers a wide range of uses throughout the home. In addition to traditional monitoring of entrance doors and windows, the sensor can also be used to monitor cupboards, fridges, storage spaces, or any area where you want to keep track of access to stored items. It finds practical use, for example, on medicine cabinets, cupboards with valuables, or other spaces where it's important to know when they have been opened. Thanks to its compact size and simple installation, the sensor can be easily adapted to the various needs of your household.
Check Security Status Anytime in the App
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 allows you to check the status of connected doors or windows at any time directly in the eWeLink app. The user has an instant overview of whether the sensor is in normal mode, whether it has been opened, or whether tampering has been detected. The Tamper Detection feature alerts you to any attempt to remove or damage the sensor, helping to keep your home better protected. A clear status log makes it easy to monitor security and manage subsequent smart scenes.
Battery Status Always at Hand
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 continuously displays the battery status directly in the eWeLink app, so you always have an overview of the remaining capacity and can plan its replacement in time. Powered by a standard AAA battery, there is no need for complicated charging or special accessories. The long battery life of up to 3 years ensures reliable operation with minimal maintenance requirements.
Automatic Response to Security Breaches
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 can instantly trigger linked security scenes when it detects a door or window opening. In conjunction with compatible devices, you can, for example, activate an alarm on a Zigbee gateway, switch the system to security mode, or automatically start camera recording. Linking with smart home devices allows you to create comprehensive protection that responds to a breach quickly and without the need for manual intervention.
Flexible Installation for Different Types of Doors and Windows
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 is designed to be easily adapted to various designs of doors, windows, and frames. Thanks to its clever design, it can also handle places where there is a larger gap between the sensor and the magnet or where standard sensors may not be suitable. The detachable magnetic part facilitates installation even in non-standard spaces and allows for convenient placement according to the specific situation.
- Detection distance up to 30mm: When the magnet is installed horizontally, it allows for reliable detection even on doors and windows with a larger gap. When installed vertically, the detection distance is 15mm.
- Vertical magnet mounting: A suitable solution for doors and frames with a height difference where traditional mounting may not be practical.
- Detachable magnetic design: Allows for easier installation in narrow or unusual places and increases the sensor's usability in different households.
Save Energy with Smart Scenes
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 not only helps with home security but also with more efficient energy use. The status of doors and windows can be used as a trigger for automations, for example, to automatically turn off the heating when a window is left open for a long time or to turn off the lights after closing a space. Smart linking with other devices helps prevent unnecessary energy loss and increases comfort in daily household use.
Voice Control of Door and Window Status
The SONOFF SenseGuard DW Gen2 SNZB-04PR2 allows you to conveniently check the status of your doors or windows using voice assistants. After linking with supported platforms like Amazon Alexa or Google Home, you can simply ask about the status of the front door, for example, and get an instant answer without opening the app. This feature simplifies daily household checks and provides a quick overview of your home's security.
Note: Voice control requires adding the device to the eWeLink app and then syncing it with supported platforms via cloud integration. Direct connection to a third-party gateway is not used for this function.
