## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by A***N on 3 August 2026*

Does the job as it should. Very simple to use and setup.

### ⭐⭐⭐⭐⭐ Must have for anyone that's had to deal with a leak in the past.
*by C***R on 6 May 2026*

Very easy to set up, and the Wi-Fi notification is brilliant. We had a leak with our washing machine, so this was perfect to put underneath just in case the leak occurred again. Very small in size. Definitely needed if you want peace of mind.

### ⭐⭐⭐⭐ 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!
