Review: nice water leak sensor！ - This water leak sensor works great! I placed it in the laundry room, kitchen, and guest bedroom, and it detects water instantly. The alarm is loud, and I get immediate alerts on my phone. It already helped me catch a small leak near the washing machine before it became a bigger issue. The one in the kitchen gives me peace of mind under the sink, and the sensor near the guest bathroom adds extra protection. Easy to set up, reliable, and definitely worth it for home safety!
Review: Perfection for Midwest US basement! - Absolutely perfect for our needs. When it rains really hard from the north, we get water in our basement. Thisis loud enough, it wakes me from a dead sleep when it does off. Perfectly sensitive; Just a touch of water and it goes off. I just lay it on the ground, arm it and it works... Super easy! Plus, not having to buy a gub makes it a cheap and effective tool. Easy set up on wifi too!

## 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.

### ⭐⭐⭐⭐ Good, but here is how it could be better
*by N***Y on August 27, 2025*

These little things work very well...they go off with even the slightest bit of water . the alarm is a decent level of loud depending on the size of your home and where its located. I have them near toilets and near my water heater, laundry. Under sinks. where there are high pressure water lines. I wish they could link to a wifi/or direct device to device connection to an emergency shut off valve. thats my only issue with it...(unless im missing something) but letting you know you have a leak is cool, shutting the water off at the main is Great!! becuz after it tells you there is a leak...if you are not home, OMG, u will freak out and then have to get home...so having it be able to link to a emergency auto shut off valve would complete the circle . they should make one , then this system would be Amazing
