Detection at the highest level - effectiveness and resistance
The Sonoff SNZB-05P sensor features a well-thought-out design - the concave surface collects water, allowing for instant detection of even the smallest leaks . Gold-plated probes provide corrosion resistance, and the IP67 housing guarantees longevity and reliable operation even in humid environments. The additional WLDC200 cable allows for flood detection along its entire length , which increases the scope of protection, e.g. in basements, under boilers or HVAC installations.
ZigBee 3.0 - stable connection in every situation
ZigBee 3.0 is a fast and energy-efficient communication protocol that allows the sensor to maintain constant communication with the gateway even at a distance of up to 130 m in open space. This makes the system immune to WiFi interference , and local ZigBee scenes work even in the absence of Internet access, enabling the activation of the gateway's sound signal and automation with other devices.
The sensor requires connection to a ZigBee gateway - e.g. ZBBridge/-P/-U, NSPanel Pro or iHost .
Smart Home Integration - Full Control via eWeLink
The SNZB-05P + WLDC200 set integrates seamlessly with smart home ecosystems such as Amazon Alexa, Google Home, SmartThings or Home Assistant (ZHA/Zigbee2MQTT). The eWeLink application offers extensive water detection notifications - push, sound and e-mail (for subscribers). The ability to create automation and local scenes increases safety - the sensor can, for example, automatically turn off the solenoid valve or notify about a leak in real time.
Practical applications
The Sonoff SNZB-05P set with the WLDC200 cable will work wherever water leakage can cause damage: in bathrooms, laundries, kitchens, basements, under dishwashers, refrigerators or water tanks . Thanks to its compact dimensions and the possibility of flexible cable arrangement, you can adapt the installation to the specifics of the room. It is also an ideal solution for home automation users - the sensor can become part of a larger security system.
