Review: You need them! Buy them before the leak or you will after! - Yes, this is one of the devices that most people don't prioritize having or just start to discover their existence after a leak happened. Well, I've learned it the hard way after a pipe burst in attic and there was water damage all the way to the ground floor. And funny point is that in life we all pay sometimes a ridiculous amount of insurances, some compulsory, some by choice but often useless. These flood sensors are your kind of equivalent of insurance or better said prevention from consequences of a heavy flood, just long term and relatively cheap. And if we consider what major leaks can cost - then super cheap. Let me quickly summarize the key points so far: 1. Works and works fast. Either leaks or drips, once the liquid touches the sensor you will know instantly. Just make sure you are positioning it correctly and if possible in such places so you avoid false alarms. What do I mean? Well I've placed one of mines in the bathroom corner, close to the toilet. One of the evenings we all simply jumped up of the loudness of the alarm, which was due to my sons poor aiming in the toilet. I'm under impression that loudness and unexpected scream scared him so much that it made the aiming situation even worse haha. By the way don't worry, you can change the alarm volume and duration and this is exactly what I did after this case. 2. Decent app and good notifications. Well, this one is as important as the device itself, because if leaks happen when you're not home - you want to know about this fast and be able to act fast too. Actually, it's important when you're at home too. Beside reminders and emails - the phone pop-ups are very informative and useful. Just make sure you allow them! Setup was quick and straightforward, there is no rocket science behind it. I've tested it so far with Alexa and it works. I expect it to work with other claimed services from Google and Siri, but I'd personally won't rely on this as number one interaction or communications channel. I hope for my Alexa just to notify me when batteries are low - this will be super helpful, as obviously you want these sensor to be on and running and not dead if a leak happens. Connectivity throughout the house for me is also good, but make sure to test it if you live in castles or spread multiple sensors in separately standing granny flats, garages, etc. Don't just trust the claimed 120 meters as it will depend a lot on build materials, interference, etc. To summarise: This is a device that you hope that you will never need, but trust me you want it to be in your house just in case, for peace of your mind, because if a leak happens, you will thank yourself a lot. And if you knew about such sensors and did not buy one - it will be bitter! Anyway, hope my 5 cents help a bit. Stay well and dry haha! Cheers!
Review: Rilevatore di perdite SwitchBot: semplice da installare, affidabile e intelligente - Ho acquistato il rilevatore di perdite d’acqua SwitchBot a gennaio 2025 per installarlo vicino alla caldaia, così da prevenire eventuali perdite o gocciolamenti. Dopo diversi mesi di utilizzo si è dimostrato un prodotto affidabile e molto utile. L’installazione è semplicissima: si configura in pochi minuti tramite l’app SwitchBot, senza bisogno di hub, e può essere posizionato facilmente anche in spazi ristretti. Il sensore rileva immediatamente la presenza di acqua e invia notifiche istantanee sullo smartphone, oltre ad attivare un allarme sonoro ben udibile. Ottima anche l’affidabilità nel tempo: nessun falso allarme e batteria ancora in ottime condizioni. Per chi ha una caldaia in casa o in un locale tecnico, è una soluzione pratica ed efficace per aumentare la sicurezza e prevenire danni. Rapporto qualità-prezzo eccellente. Consigliato senza dubbi.

## Features

- Real-time notifications (no hub needed): After connecting to Wi-Fi, you can receive real-time notifications via email and remote app when drops, leaks or floods are detected, without the need to purchase an additional hub. Share devices with the family and they can also check the status of the house at any time (2.4GHz Wi-Fi and BLE)
- High sensitivity drip alarms: This device is equipped with four sensor sensors at the top and bottom, which can detect a low water level of only 0.5 mm. If the water pipes drip and your soil becomes submerged or wet, the alarm will sound. The water leak detector is compact and practical in size, suitable for placement in laundries, water heaters, dishwashers, sinks and other places.
- Contains loud alarm noises: To help you stay alert, we have added 100dB high level alarms, which means that even if there is a leak in the basement or in slightly more remote places, you will know in time. Once discovered, you can silence it manually without worrying about sound issues.
- IP67 waterproof, up to 24 months battery life: The water leak detector is designed with a fully sealed waterproof shell and can handle high humidity working environments without any problems. It comes with 2 AAA batteries and has a lifespan of up to 24 months. If the battery is low, our app will also send you notifications to remind you to replace them in time
- Part of SwitchBot ecosystem, voice control compatible: use with SwitchBot Plug Mini or Indoor Cam, remotely turn off electrical equipment or check the status of your home if there is a leak. 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.

### ⭐⭐⭐⭐⭐ 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!
