Review: Smart, Well Designed & Home Assistant Ready – Spot on from SwitchBot - I couldn’t be more impressed with this leak detector. The cabled version is fantastic value, effectively giving you three sensors in one. The engineering is smartly thought out — the top-mounted sensor sits in a dished recess, which cleverly allows drips to collect and trigger the alarm more quickly. It also has a built-in alarm for immediate local alerts, which is a lifesaver if you’re nearby. Connectivity is excellent: it works flawlessly with the SwitchBot app and cloud services, but it also integrates perfectly with Home Assistant via ESP32. In fact, setup with HA was even faster and more seamless than with the official app. Someone mentioned it didn’t work, personally didn’t have a single issue getting it to work. It was picked up by ESPHome instantly. I was torn between this and the Eufy option, but honestly this has far more bells and whistles, and the Home Assistant functionality is spot on — exactly what I needed for my setup. The build quality, design, and reliability are outstanding. I had the unfortunate experience of a copper pipe bursting (after rubbing against a rusty RSJ), which flooded two rooms in my office. I only wish I’d bought this device sooner — it would have saved me a lot of hassle. If you’re looking for a well-designed, highly reliable, and affordable leak detector, this is absolutely the one to get. ⭐ ⭐ ⭐ ⭐ ⭐
Review: Brilliant Water Sensor! - The SwitchBot WiFi Water Sensor is an absolute game-changer for home protection! Setting it up was a breeze — just connect it to your 2.4Ghz Wi-Fi, and you're good to go. No extra hub needed, which is a huge plus. The app is intuitive and user-friendly, delivering real-time alerts straight to your phone whenever it detects leaks, drips, or flooding. It’s fantastic for peace of mind, especially when you’re not home. The build quality is impressive, with an IP67 waterproof rating, making it perfect for kitchens, bathrooms, basements — pretty much anywhere. The sensitivity of this thing is unreal. It has four sensor probes and can detect even a tiny 0.5mm water level! And if something goes wrong, the 100dB alarm ensures you won’t miss it, even from afar. The app integration is smooth, and I love how it works with Alexa, Google, Siri, IFTTT, and SmartThings. It even pairs with the SwitchBot ecosystem, letting you control other devices if a leak occurs. All in all, this little device packs a serious punch. It's reliable, well-built, easy to set up, and the app makes everything super convenient. Highly recommend!

## 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.

### ⭐⭐⭐⭐⭐ Life saver bit of kit
*by C***N on 28 October 2025*

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!
