SwitchBot WiFi Water Leak Detector, No Hub Required (Support 2.4G), Smart Water Detector 100dB Adjustable Alerts & App Alerts, IP67 Waterproof, Wireless Detector for Kitchen, Bathroom, Basement

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!

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. ⭐ ⭐ ⭐ ⭐ ⭐

I have several products now by this brand. I am very impressed with them all. These leak detectors quality, look and feel or the products is really good. These leak detectors are a great idea. I found them really easy and quick to set up. Testing the alarm and sensors worked well. Loud alarm too. I have one in my airing cupboard, one in a bathroom and one under my kitchen sink……all three locations have had leaks before, so am wary of it happening again. Would absolutely order again and very happy to recommend

Performance The sensor is highly sensitive and reliable. During my tests, it detected even small amounts of water quickly. The dual detection system, which senses both water and high humidity, is a fantastic feature for versatile monitoring. The notifications sent to my phone were instant, allowing me to address potential issues promptly. Battery Life Powered by AAA batteries, the sensor boasts an impressive battery life of over a year, depending on usage. The app conveniently notifies you when the battery is running low.

First off, the price - it's good. SwitchBot have made a solid, well designed, clean and functional device. I love the small variance in the sensors. The detection pins are located on both sides of the unit. One set are flush and one slightly indented. This alters the moment of detection, which is a nice, subtle touch. And the extra sensor tail means that the single device can monitor two locations at the same time. So, for example, I have the unit in the drip tray and the external sensor on the floor. This covers several potential failure points in my watering system. It was so easy to connect to wifi. No extra hub is needed and the Switchbot app gives some nice functionality. Changing the volume of the siren, duration and interval gives some nice control options, and (this is the best bit), this little unit can be flipped into a water level warning sensor. This is a cool function for those alternate scenarios. So, to conclude. I looked at the options and chose Switchbot because they make quality smart devices that perform to their specifications and they are reliable. They also integrate seamlessly into my home both technically and aesthetically.

Wonderful product . Tested the switchbot many times and it worked flawlessly. For me, the setup was easy and it gives me a piece of mind. If I have a leak at the house, and if I'm not home, the app will send me a message to my phone saying I have a problem .

Easy to set up, easy to use. Handy multiple points with the cable to get it into difficult spaces. Also works with Homey.

J’ai acheté le détecteur de fuite d’eau SwitchBot pour sécuriser mon appartement, et j’en suis très satisfait. L’installation est ultra simple : il suffit de placer le capteur à l’endroit souhaité et de le connecter à l’application SwitchBot, sans besoin de hub supplémentaire. Je l’ai installé sous mon chauffe-eau et je prévois d’en installer un autre prochainement sous mon évier équipé d’un système de filtration avancé. Le détecteur est très sensible, il réagit immédiatement à la moindre trace d’eau et déclenche une alarme sonore. J’apprécie aussi la réception de notifications instantanées sur mon smartphone, ce qui me rassure même lorsque je ne suis pas chez moi. Le design est compact et discret, il se glisse facilement sous un évier ou près d’une machine à laver. L’autonomie annoncée est excellente, et il fonctionne avec des piles classiques. Le rapport qualité-prix est vraiment bon pour un appareil connecté de ce type. Je recommande ce détecteur à tous ceux qui veulent éviter les mauvaises surprises liées aux fuites d’eau !

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.

initial issue: I placed the batteries, and tried the sensor cable, it straight up doesn't work, the sensor on the front of the device does, but no the back and the sensor cable, useless Edit: there are tiny pins behind the device, if you realize that your cable doesn't work either, push the pins forward with something and put the cache back on this device is amazing, you get an alarm that you can tone down or straight up disable it, and still have the notifications on your phone, i use it in a 70L trash bin that i use to store water for aquarium water changes that i have marked with different quantities of water (20,30,40,50,60L) i placed the cable sensor in and hold it with a magnet on the exterior so i can adjust the height of it and get a notification when my RO water reaches the desired amount of water i need
