water leak detector Zigbee — SONOFF SNZB-05P is an innovative water leak detection system, which uses modern Zigbee 3.0 protocol technology. This device is designed to quickly and accurately detect water leaks in any environment – from the basement to the sink under the counter. The main benefit of the leak detector is direct notifications to your smartphone, which help you react quickly to water damage. With this device, you can protect your property from expensive repairs and water consequences.
Using the Zigbee water leak detector is ideal for homeowners who want to protect their property from water damage. Popular use cases include basements, laundry rooms, kitchens under the sink, and bathrooms. This device is suitable for both renters and homeowners who want extra security. The expandable cable system allows for monitoring on curved surfaces and in complex areas. Set notifications on your phone and you will see the threat as soon as it appears.
Q: What is the control range of the water leak detector?
SONOFF SNZB-05P uses the Zigbee protocol, which provides a control range of about 100 meters in open space. Within home limits, this easily provides sufficient security. The distance may decrease if there are many walls, but the Zigbee network can use a repeater to strengthen the signal.
Q: Does the device work without a WiFi connection?
Yes, one of the main features of the SONOFF SNZB-05P is the local Zigbee scene, which works even if your WiFi network is down. The gateway sound signal will be issued automatically when water is detected, providing extra security and reliability in critical situations.
Q: Is an additional detection cable required?
SONOFF SNZB-05P can operate independently with the raised probe and water collection system. However, if you want wider monitoring, you can buy an additional detection cable separately or include it in the sensor kit. The cable connects without any length restrictions.
SONOFF SNZB-05P is a reliable and innovative solution for monitoring water leaks. Smart home enthusiasts and sustainable businesses appreciate the capabilities of this device, and its Zigbee integration provides complete control through smart systems. The use of the water leak detector via Zigbee starts today to protect your home from costly water damage.

Excellent device, impeccable design and manufacturing! Relatively new, you can purchase the smart sensor separately or a kit with a moisture-sensing wire. It has a variety of uses: by turning the sensor contacts down or placing it on the wall (improving the connection to the zigbee network) and using the additional sensing wire, you monitor leaks on the floor. By turning the sensor contacts up and placing it under a faucet or pipe, you monitor water leaks from above. The device easily connects to the native ewelink app using a qr code (zigbee gateway is required). It works perfectly with the z2m add-on and integrates with the home assistant server ( zigbee coordinator is required). Excellent seller, excellent service, and a perfect device! Thank you! 🙂

It took a long time. Alisa quickly processed it through the hub and registered it. The battery is included. It works perfectly and is lightning fast!!! Just a couple of drops of water and it works immediately. For Belarusians, only push notifications and SMS messages are received. But for residents of Russia, you can also set up a phone call notification… I recommend it to everyone. Wishing everyone peace and goodness.

Sonoff SNZB-05P water leak sensor
I purchased several of these sonoff snzb-05p sensors and they arrived within the expected timeframe. They function as described and provide a decent level of peace of mind for leak detection. Compared to the cheaper, generic zigbee sensors i’ve seen, the build quality here is notably more solid and less flimsy.
The expected battery life is better than unbranded alternatives, which makes the price difference acceptable. Another practical benefit is the support for firmware updates, which helps with long-term stability. Overall, it is a reliable, well-engineered device that does its job without any issues.

Essential peace of mind with the SNZB-05P
I’ve purchased several of these sonoff snzb-05p water leak sensors and they work exactly as they should. When it comes to flood detection, you really need a device you can trust, and these provide total peace of mind. As expected from sonoff, the build quality is excellent and feels much more solid than the flimsy, generic zigbee alternatives.
The superior battery life expectation alone makes these worth the slight price differential compared to unbranded sensors. Knowing i can receive firmware updates to keep the devices stable is another huge benefit. If you want a reliable, well-engineered sensor to protect your home from water damage, this is the one to get.

Not sure if it’s a product fault. disconnects constantly despite proximity to hub.
