Xiaomi Water Guard 2: Smart Leak Detector for Your Home
Xiaomi Water Guard 2: Your Smart Home’s Leak Detection Superhero
Water leaks – they’re the silent home invaders! They can cause a ton of damage and leave you with a massive headache (and bill!). That’s why Xiaomi’s new Xiaomi Water Guard 2 is such a welcome addition to the smart home scene. Released in October 2025, this compact and affordable leak detector promises to keep your home dry and worry-free for up to three years on a single battery. Let’s dive into what makes this little gadget a must-have for every homeowner.

Why a Water Leak Detector? Seriously?
Think about it: leaky pipes, overflowing washing machines, even just a dripping faucet can lead to serious water damage. We’re talking mold, ruined floors, and sky-high repair costs. As xiaomi news becomes more prevalent, and with the increasing frequency of extreme weather events, early detection is more critical than ever. Xiaomi, already a major player in the smart home ecosystem, steps up with the Water Guard 2, an upgraded version of their original leak detector. It boasts improved sensors and seamless wireless connectivity, aiming to set a new standard for home disaster prevention. You can check more details about it at Xiaomi Water Guard 2 release. This aligns with the growing trend of smart home tech focused on everyday problems.
Xiaomi Water Guard 2: Key Features That Make a Difference
The Water Guard 2 isn’t just another sensor; it’s a carefully designed device packed with features to keep your home safe.
Multi-Scenario Detection: All-Around Protection
This little device has you covered for different types of leaks. It has dual probes on the base to pick up both slow leaks (gradual water build-up) and sudden floods (water level exceeding 0.5mm). But here’s the cool part: it also has a top-mounted water collector. If water sprays or drips onto both upper probes, it triggers a special alarm – perfect for protecting against rogue splashes from the sink!
Smart Alerts: Always in the Know
- Local Sound and Light: Even without an internet connection, the built-in buzzer and flashing LED will alert you to a leak.
- Remote Notifications: Get instant alerts on your smartphone via the Mi Home app. You can even customize the alert frequency for smarter risk management.
- Ecosystem Integration: The Water Guard 2 can trigger alarms on other compatible devices, like smart plugs or robot vacuums, creating an automated response system. Imagine a smart plug cutting off power to your washing machine the moment a leak is detected!

To get started, all you have to do is download the MIUI app, add it to your device list, and place it where you need protection the most.

Real-World Benefits: Peace of Mind in a Tiny Package
Picture this: You’re on vacation, and a burst pipe floods your kitchen. With the Water Guard 2, you’d get an alert on your phone, allowing you to remotely shut off the water supply (if connected to a smart valve). This can save you thousands in repairs and a whole lot of stress. For families with kids or pets, or those living in areas prone to heavy rains, like parts of Argentina, this device is a smart investment in peace of mind. Also consider looking at products from Mijia for other smart home devices.

The Xiaomi Water Guard 2 initially launched on Xiaomi Youpin in China. However, a global rollout is expected in the coming months via platforms like AliExpress, Amazon, and the official www.mi.com store. Keep an eye on local importers or the Mi Home app for updates on availability in your region.
