Extreme Rains on the Horizon: Why Invest in Water Protection Now

The Czech Hydrometeorological Institute has expanded and intensified the warning for heavy rains that will affect the eastern part of the country in the coming days. According to meteorologists, up to 180 millimeters of precipitation could fall in the Beskydy mountains, and around 130 millimeters in the Jeseníky mountains. These extreme rains will be most intense on Wednesday night and Wednesday morning, when up to 20 mm per hour could fall.

The warnings primarily concern the Zlín Region and parts of the Moravian-Silesian, Olomouc, South Moravian, and Pardubice Regions. The highest risk is in the area of Český Těšín, Jablunkov, and Třinec, where the highest warning level is in effect. Even if you don’t live directly in a flood-prone area, heavy rains can cause problems even in ordinary households – from leaks through the roof or windows to backflow in the sewage system.

In such situations, timely detection of water leaks is crucial. The SONOFF SNZB-05P can detect liquid levels as low as 0.5 mm and immediately notify you via the mobile app, giving you time to react before serious damage occurs.

How the SONOFF SNZB-05P Works and Where to Place It

This smart detector uses Zigbee 3.0 technology for reliable communication up to 130 meters in open space. You need a Zigbee hub for its operation, such as SONOFF ZB Bridge, NSPanel Pro, or iHost. The sensor can also be integrated into popular platforms like Home Assistant or Zigbee2MQTT, which will be appreciated by more advanced smart home users.

Thanks to its IP67 certification, the sensor is fully waterproof and dustproof, so you can safely place it even in areas where direct contact with water is likely.

Ideal places to place the SONOFF SNZB-05P sensor are:

• Under the washing machine or dishwasher – a common source of water leaks in the home
• Near water connections – in the bathroom, kitchen, or utility room
• In the basement or cellar – where there is a risk of groundwater seepage or leaks during heavy rains
• In the attic – for detecting roof leaks
• Near the boiler or heating system – where there may be a risk of water leaks from the system

An interesting feature is the possibility of connecting an extension cable, which allows detecting water leaks over a larger area or in hard-to-reach places. These cables can also be connected in series without length limitation, which is ideal for securing an entire room or longer sections.

Practical Features and Benefits

The SONOFF SNZB-05P stands out with several practical features:

• Long battery life – the sensor can operate for more than 5 years on a single CR2477 battery, so you don’t have to worry about frequent replacements
• Instant notification – in case of water leak detection, the sensor will notify you via a push notification in the eWeLink app
• Works even without WiFi – thanks to local Zigbee scenes, the sensor can activate the gateway’s audible alarm even if the WiFi connection is lost
• Customizable alerts – in addition to push notifications, you can set up alerts via email or SMS (with the eWeLink Advanced plan)

Thanks to its raised design, you can place the sensor even on metal surfaces without affecting its functionality. It can detect even minimal amounts of water (from 0.5 mm), ensuring early warning before the leak becomes a real problem.

Final Summary

Given the current meteorological warnings for extreme rains, protecting your home from water is more relevant than ever. The SONOFF SNZB-05P Zigbee Water Leak Sensor at the current price of 279 Kč with code ALZADNY30 represents an affordable investment in the peace and safety of your home.

Given the expected heavy rains in the coming days, now is the ideal time to acquire this useful helper. Preventing tens of thousands of crowns in damage with an investment of less than 300 Kč is a decision that clearly pays off.
