## Description

Compact, waterproof WiFi detector with 100dB alarm sends instant phone alerts for leaks/flooding without needing a hub. Real-time notifications for you and family.

Review: Life saver bit of kit - This is a great little piece of kit that has helped me whilst away. It actually activated whilst I was travelling so I could send somebody around to have a look. Turned out to be a false alarm but thankful for it letting me know rather than coming home to a water leak. It’s easy to use and set up. The iPhone app is straightforward and uses notification alerts. I’ve had this for a few months and the battery seems to be OK. I have recommended this sensor to others and will be buying more in the future. A quick, easy, and cost effective way to protect yourself and your home!
Review: Works with WIFI without any extra equipment. - Installation is easy. Download the app, register, add the batteries, it auto detects then add your 2.4Ghz wi-fi details. Once it connects to the cloud service and you have allowed notifications you get email and notifications once the detector detects even a small amount of water 0.5mm. Initially on the app I thought there was a problem with WIFI because the service was greyed out saying bluetooth was lost... This is NOT a problem as this situation occurs because the device to save power only connects to WIFI once it detects water and alerts. The alerts came thru very quickly. A good bit of kit for an early alert of water somewhere :-)

## Features

- Real-time Notifications (No Hub Needed): After connecting to Wi-Fi, you will be able to receive real-time email and app notifications remotely when dripping, leaking, or flooding is detected, without the need to purchase an additional hub. Share devices with family, and they can also check home status at any time. (2.4Ghz Wi-fi & BLE)
- High Sensitivity Drip Alarms: This device is equipped with four sensor probes at the top and bottom, which can detect a low water level of just 0.5mm. If water pipes drip, and your floor is submerged, or gets wet, it will sound an alarm. Water Leak Detector is compact and convenient in size, suitable for placement in laundry rooms, water heaters, dishwashers, sinks, and other places.
- Water Level Detection: Equipped with a 1-meter extended probe, you'll be able to detect changes in water levels of places like swimming pools, bathtubs, and fish tanks. It can also be placed in narrower areas, such as bottom of refrigerators or back of washing machines. And is suitable for homes, warehouses, basements, sinks, water heaters, pipelines, and more.
- IP67 Waterproof, Up to 24 Months Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments.

## Questions & Answers

**Q: How to test and verify SwitchBot App alerts and notifications?**
A: Ensure the SwitchBot App is updated, the Water Leak Detector is added with notifications enabled, Bluetooth is off, the device is submerged to trigger an alarm, and wait 30-120 seconds for Wi-Fi connection; if no alerts, check Wi-Fi or relogin.

**Q: Why is there a delay in receiving alerts from the Water Leak Detector?**
A: To save battery, Wi-Fi only activates when water is detected, taking 30-120 seconds to connect. This delay is by design for power efficiency. Use a Hub near the detector for faster alerts.

**Q: How to set up SwitchBot Water Leak Detector email notifications?**
A: Update the SwitchBot App, add the detector, then go to Profile > Preferences > Email Notifications > Important Device Notifications. Select your detector, enable "Email Alerts," and add your email. For help, reach out to us via App > Help & Feedback.

### ⭐⭐⭐⭐ All In All: Neat & Functional, but Fiddly
*by P***Y on 10 October 2024*

Slightly fiddly to set up and pair with WiFi via the iOS app - not helped by somewhat garbled instructions that have to be downloaded from a QR code. Apple HomeKit integration is not terribly clear. That said, the sensor is neat, very compact and easily placed alongside any boiler, water heater, dishwasher or laundry appliance. Having tested the alarm, the smallest spillage or leak seems to trigger the alarm and/or email alerts (as programmed). The on-board, physical alarm is sufficiently loud, but suitably time-limited so as to not disturb neighbours unduly if you are away from home if a leak occurs!
