Product information

Description

The Meross MS405-EU Smart Water Leak Sensor is a reliable solution designed to protect your home from water damage by providing real-time monitoring and instant alerts. This compact device is engineered to detect moisture and leaks early, allowing you to take immediate action before minor issues escalate into costly repairs. By integrating into your smart home ecosystem, it ensures you stay informed about the status of your plumbing and appliances, whether you are at home or away.

Advantages

This sensor offers a dual-detection system with probes on both the top and bottom, ensuring it captures leaks from dripping pipes or pooling water on the floor with high sensitivity. It features a powerful 100 dB built-in alarm that provides an immediate audible warning, while the smart connectivity ensures you receive push notifications directly to your smartphone. The device is built to last with an IP66 rating, making it resistant to dust and water, and it is powered by long-lasting batteries that provide up to three years of operation. Its compact and wireless design allows for discreet placement in tight spaces, and it integrates seamlessly with major smart home platforms for centralized control and automation.

Suitable for

  • Monitoring under kitchen and bathroom sinks
  • Detecting leaks near washing machines and dishwashers
  • Protecting basement areas prone to flooding
  • Monitoring water heaters and utility rooms

This sensor may not be suitable for outdoor environments exposed to extreme weather conditions beyond its specified operating temperature range. It is also not intended for use in areas with high levels of steam or condensation that could trigger false alarms, and it requires a dedicated Meross hub to function within a smart home network.

Key specifications

  • Alarm volume: 100 dB
  • Protection rating: IP66 (dust and water resistant)
  • Power supply: 2 x AAA batteries
  • Dimensions: 63 x 63 x 27 mm
  • Connectivity: 433 MHz to hub, Wi-Fi 2.4 GHz hub support
  • Compatibility: Apple Home, Google Home, Amazon Alexa, Samsung SmartThings

How to use

To begin using the sensor, first ensure your Meross hub is properly connected to your home Wi-Fi network. Insert the provided batteries into the sensor unit. Use the Meross mobile app to pair the sensor with the hub by following the on-screen instructions. Once paired, place the sensor in a location where water leaks are most likely to occur, such as on the floor near a water source. Ensure the detection probes are in contact with the surface where water might accumulate.

What to consider before purchase

  • A Meross hub is required for the sensor to operate and connect to your smart home system.
  • Check that your home Wi-Fi network operates on the 2.4 GHz frequency.
  • Ensure your smartphone meets the minimum operating system requirements (iOS 13 or Android 8.0).
  • Verify that the installation area is within the recommended operating temperature range of 0°C to 40°C.

Usage recommendations

Regularly test the sensor by placing it on a damp cloth to ensure the alarm and app notifications are functioning correctly. Check the battery levels periodically via the app to maintain continuous protection.
