1. Produktet er slutview
The Xiaomi Smart Water Leak Sensor 2 is designed to detect water leaks and flooding in various household scenarios. It features a 'soaking and watering double guard' detection mechanism, multiple alarm methods, and a long-lasting battery. The sensor integrates with the Mi Home APP via Bluetooth 5.2 for smart home automation.


2. Opsætning og installation
2.1 Forudsætninger
- A Xiaomi Bluetooth Mesh gateway is required for network connectivity and automation. The sensor does not support Zigbee connection.
- The Mi Home APP must be installed on your smartphone.
- For the Chinese version of the sensor, ensure the region setting in the Mi Home APP is set to 'China' and the preferred language is also set accordingly before adding the device.
2.2 Fysisk placering
The sensor is designed for easy, plug-in-free installation. Simply place it in areas prone to water leaks.

Recommended placement locations include:
- Under kitchen wash basins
- Next to the water inlet and outlet of washing machines
- Easy-to-enter positions of window sills
- Badeværelse gulve
- Near the water inlet and outlet of sweepers/robot vacuums

2.3 Pairing with Mi Home APP
Follow these steps to connect your sensor to the Mi Home APP:
- Open the Mi Home APP on your smartphone.
- Log ind på din konto.
- Click the "+" icon in the upper-right corner of the APP homepage.
- Select "Add device".
- Choose "Xiaomi flood guard 2" (or similar name for the water leak sensor).
- Follow the on-screen prompts to complete the device pairing and configuration.

Note: Due to continuous updates of the Mi Home APP, actual operation steps may vary slightly. Always refer to the latest instructions within the app.
3. Betjeningsvejledning
3.1 Lækagedetektion
The sensor employs a dual detection mechanism:
- Bottom Double Probe Design: When the water height reaches 0.5mm, the flooding alarm will be triggered, providing an early reminder of potential leaks.
- Top Poly Water Design: If the water level covers the top two probes, conduction will trigger an alarm, addressing complex hidden dangers.


3.2 Alarm Methods
The sensor provides multiple ways to alert you to a water leak:
- Acousto-optic alarm: A built-in buzzer and indicator light provide a local alert, allowing you to quickly locate the leak. This alarm functions even when offline.
- MIJIA APP smart alarm: Receive remote notifications on your smartphone, with options for alarm frequency customization and monitoring of risk dynamics.
- Smart device alarm: If connected to other smart devices (e.g., smart speakers, displays), these devices can play an alert tone.


3.3 Smart kobling
The sensor supports Xiaomi surging zhilian, allowing for personalized intelligent linkage scenes with other smart home devices. For example, if flooding is detected, a smart wall socket can automatically power off connected household appliances to ensure safety. Note that linkage scenarios need to be created through the MiJIA APP, and other linkage devices must be purchased additionally.

4. Vedligeholdelse
4.1 Batterilevetid og udskiftning
The sensor uses a CR2450 button battery with ultra-low power consumption design, providing an ultra-long life of approximately 3 years. This means frequent battery replacement is not necessary.


Note: The 3-year battery life is based on specific usage conditions (reporting every 15 minutes, two alarm events per year). Actual battery life may vary depending on usage. For specific details, consult official customer service.
4.2 Durability and Materials
The sensor is built with durability in mind:
- IP67 beskyttelsesniveau: It is IP67 dustproof and waterproof, making it suitable for humid environments without fear of dust or moisture.
- UV-Resistant Material: casing is made from UV-resistant material, ensuring it remains durable and does not yellow over time.
- Korrosionsbestandighed: Features nickel-plated metal probes for anti-rust and anti-corrosion properties, contributing to a longer lifespan.




5. Fejlfinding
5.1 Forbindelsesproblemer
