## Description

SwitchBot WLAN Water Detector, Smart Water Sensor, 100 dB Adjustable Alarm & App Notification, IP67 Waterproof, Water Leak Detector for Kitchen, Bathroom, Basement, No Hub Required (2.4 G)

Review: 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: Wij hadden regelmatig last van harde regen die door een kier bij het raam naar binnen komt. Nu worden we gewaarschuwd als de vensterbank nat wordt, nog voordat de vloer blank staat. Duidelijk hoorbare meldingen (instelbaar) en notificaties in de Switchbot-app.

## 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
- Includes Loud Alarm Sounds: To help you stay alert, we've included 100dB high pitched alarms, which means even if there is a leak in basements or places a little further away, you'll know in a timely manner. Once discovered, you can manually set it back to mute without worrying about noise issues
- IP67 Waterproof & Up to 2 Years Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments. It comes with 2 x AAA batteries and has a battery lifespan of up to 2 Years. When battery is low, our app will also send notifications to remind you to replace them in a timely manner. (*When used in Standy-by Mode, actual battery life performance may vary depending on use.
- Part of SwitchBot Ecosystem, Voice Command Compatible: Use with SwitchBot Plug Mini or Indoor Cam, and remotely turn off electrical equipment or check the condition of your house in case of leakage. It can also support third-party services such as Alexa/Google/Siri/IFTTT/SmartThings

## 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.

*by T***Y on 17 January 2026*

Brilliant ! I have installed cameras, door devices, routers, temp guages in 2 locations, and this is the only device of the bunch that just works, No complexity, very reasonable, and part of what gives a small discount from insurers. The fact that it does not need a router makes it much more fail resistant. If I get a water leak, I get a notification and an email. If the battery goes low, I get notifications(and they aren't supposed to be hard on batteries). If I go away for a while, I can see battery state on app. I'm rarely this enthused about a product.
