Xiaomi launches new Water Guard 2: Get alerts even before water leakage occurs
Continuing its streak of innovation in smart home and safety products, Xiaomi has introduced another unique device. On 10 November 2025, the company officially launched its new smart sensor, Xiaomi Water Guard 2, in China. This small yet highly useful smart home device is designed to send instant alerts in case of water leakage or seepage in homes.
According to the company, the device not only detects water leakage but can also issue alerts before the situation worsens, helping users prevent damage in time. Whether it’s water dripping under your washing machine or a minor pipe leak in the bathroom — the Water Guard 2 stays vigilant in every situation.
Sleek design and durable build quality
The Xiaomi Water Guard 2 features a compact and modern design. Measuring just 55 mm in diameter and 19.5 mm thick, it comes in a circular shape that can be easily placed on the floor or near the base of a wall. The outer shell is made using a dual-colour injection moulding process, giving it not only a durable build but also a premium appearance.
The device comes with an IP67 rating, making it completely resistant to both dust and water. This means it can function efficiently even in highly humid environments such as kitchens, bathrooms, or basements where moisture levels are high. In terms of build quality, Xiaomi has used UV-protected and nickel-plated materials, ensuring the device maintains its new-like look for years.
Dual-sensor technology for precise detection
The standout feature of the Water Guard 2 is its dual-sensor technology, which makes it one of the most accurate leakage detection devices in its segment. According to Xiaomi, the device includes two types of sensors — one at the bottom and another on the top.
The bottom sensor can detect as little as 0.5 millimetres of accumulated water on the floor, while the top sensor identifies falling water droplets or light splashes. In other words, whether the leak is gradual or caused by sudden splashes, the device detects both situations and alerts the user immediately.
Three types of alert systems
Once water leakage is detected, the Water Guard 2 alerts users in three different ways.
The first is a built-in buzzer alert, which emits a loud sound to immediately notify anyone nearby. The second is an LED light alert, which signals visually through the device’s light indicators. The third and most convenient option is the Mi Home app notification, which sends instant alerts to the user’s smartphone — whether they are at home or away.
One of its most useful features is that even if there’s no internet connection, the Water Guard 2 continues to operate in offline mode, using sound and light alerts to ensure the user is always informed.
Smart connectivity and HyperOS integration
Xiaomi has designed this device to integrate seamlessly with its smart home ecosystem. The Water Guard 2 connects via Bluetooth Mesh Gateway and can become part of the Xiaomi HyperOS ecosystem.
This allows it to link with other smart devices such as smart sockets, electric water valves, or sensors. For instance, if the Water Guard 2 detects a leak, the HyperOS system can automatically shut off the connected water valve, preventing further water spread.
The device supports Bluetooth 5.2 connectivity, offering improved signal coverage and faster response times compared to earlier versions.
Long-lasting battery life
The Xiaomi Water Guard 2 is powered by a CR2450 coin cell battery. With its ultra-low power design, the company claims the device can last for up to three years on a single battery replacement. This means there’s no need for frequent charging or battery changes.
Additionally, its hardware is coated with a nickel-plated, anti-oxidation layer to resist moisture and corrosion. The UV-protected material ensures durability, whether the device is placed in a sunny kitchen corner or inside a damp bathroom.
Price and availability
Xiaomi has priced the Water Guard 2 at 69 yuan (approximately ₹886), making it an affordable and practical smart home sensor. It is currently available for purchase in China through Xiaomi Youpin and other major online retail platforms.
At present, the device is exclusive to the Chinese market, and Xiaomi has not yet announced a global or Indian launch date. However, experts believe the company may soon introduce it internationally, given the growing demand for smart leakage detection systems worldwide.
Global launch
The Xiaomi Water Guard 2 has so far been launched only in China.
The company has not yet confirmed the launch date for other markets, but considering Xiaomi’s consistent global expansion in smart home technology, it is expected to arrive in major international markets soon.

Why this device matters
Water leakage is a common yet serious issue in many households. Even a small leak can damage floors or harm electronic appliances. Smart sensors like the Xiaomi Water Guard 2 help minimise such damage by providing real-time alerts, enabling users to take timely action.
The device is particularly useful in areas where water usage is high — such as bathrooms, kitchens, basements, or laundry zones. Its dual-sensor technology makes it far more accurate and dependable than ordinary water sensors.
Rising demand and consumer response
Since its launch, the Xiaomi Water Guard 2 has been widely discussed across Chinese social media and tech forums. Most users have praised its accurate detection, premium design, and affordable pricing.
Industry experts suggest that in the coming months, this device could become one of the best-selling smart safety products in China. Its smooth integration with HyperOS further strengthens its position as an essential component of modern smart home setups.
Conclusion
The Xiaomi Water Guard 2 is a prime example of how smart home technology is no longer limited to convenience — it now plays a vital role in safety and preventive action. With its accurate sensors, long battery life, and extensive connectivity options, this device could become an essential safeguard for modern households.
