Precision Water Leak Detection You Can Trust
The SNZB-05P water leak sensor is designed to catch leaks early, before they turn into costly damage. Its elevated probe and concave base allow it to detect extremely small leaks and drips from as little as 0.5 mm, making it ideal for high-risk areas such as under sinks, near washing machines, dishwashers, geysers, and water heaters. The metal-safe design prevents false alarms on conductive surfaces for dependable performance.
Expandable Monitoring for Larger Areas
For wider or more complex spaces, the SNZB-05P supports optional water leak detection cables (sold separately or as part of a sensor kit). These cables can be connected in series with no limit on total length, allowing you to monitor long pipe runs, server rooms, basements, or commercial installations with ease.
Instant Alerts — Even Without Wi-Fi
When water is detected, the sensor sends real-time app notifications so you can act immediately. Thanks to Zigbee local scenes, alarms can still be triggered through your gateway even if your Wi-Fi goes offline, ensuring uninterrupted protection when it matters most.
Seamless Zigbee 3.0 & Smart Home Integration
Built on Zigbee 3.0, the SNZB-05P integrates smoothly with compatible hubs, including:
- SONOFF NSPanel Pro
- SONOFF iHost
- ZB Bridge / ZB Bridge Pro / ZB Bridge-U
- SmartThings Hub V3
This makes it easy to add to existing smart home ecosystems and automation routines.
Long Battery Life & Low Maintenance
Powered by a CR2477 battery, the SNZB-05P delivers up to 5 years of battery life under typical usage conditions, giving you long-term peace of mind with minimal maintenance.
Battery life is based on SONOFF laboratory testing; actual results may vary.
Advanced Control with Home Assistant
For power users, the sensor supports Home Assistant via ZHA or Zigbee2MQTT (requires a Zigbee dongle such as ZBDongle-P or ZBDongle-E), enabling advanced automations, dashboards, and custom alerts.

Return of merchandise (RMA) and Warranty
We want you to be happy with the purchase you have made from us. If you are not completely satisfied, you may return the product to us and we will either refund, credit, repair/replace it, subject to the below terms and conditions.
You can return purchases for a refund (excl shipping). Please notify us within 7 days and ensure item is ready maximum 10 days after delivery date.
Please ensure to log your return request within 7 days of receipt of your item. Please ensure to select the correct reason for return:
- Changed my mind / Item exchange
- Faulty on arrival
- Incorrect item received
All items are covered by a 12 month warranty (unless otherwise stated) which will be honoured directly by GeeWiz. All products will either be replaced/repaired/refunded depending on stock availability. Products will require evaluation by GeeWiz before a warranty claim can be accepted.
Should the item being returned for assessment be found to be in good working order, unfortunately, there will be a collection fee that will apply.
The collection fees are as follows:
- For returns on items that were sent with free shipping: R198
- For returns that had a surcharge, the same surcharge will apply for collection.
Please log your return on your account, under the returns manager.
We do not reimburse your fee to ship to us, but we will pay for return shipping if the item is subject to replacement. If the item you wish to return was ordered incorrectly / is no longer required / you have changed your mind, there is a collection fee that will be charged (please refer to the above) and this will be deducted from the refund amount once the supplier has credited us. Please note GeeWiz will only cover return shipping of a faulty unit within 6 months of purchase, after which, a shipping fee (starting from R198) will be applicable to you for the return of the unit.
Any disputes relating to ordered items being short/incorrectly shipped will only be entertained if reported to GeeWiz within 3 days of delivery/collection.
Refunds are subject to inspection of item(s) - in some cases, items will need to be sent to supplier for evaluation and testing. This can take up to 15 working days. Once a refund has been approved, this may take 3 - 5 business days to be processed.
ALL returns are subject to up to a 30% restocking fee if item is no longer in BRAND NEW condition or if item seal/packaging has been broken.
Please re-package safely and include all original product packaging.

After the 6-month period, you will no longer be eligible and won't be able to receive a refund. We can however replace or repair depending on the outcome after our team of professionals has inspected the product.
Should a warranty sticker not be present on an item, the warranty is immediately null and void.
Batteries are covered under warranty, but please note that GEL, AGM and LEAD ACID have limited cycle runs. These are typically around 200 cycles and may run out before the end of the warranty. Once the cycles have been depleted, it means the battery has reached the end of life and will no longer be a warranty claim.

GeeWiz or its affiliates are not responsible for damage or loss of any kind that may occur as a result of using or misusing any product purchased from us.
