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!

Good, but here is how it could be better
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

Peace of Mind with Leak Detection
The SwitchBot WiFi Water Sensor was easy to set up and connected quickly to my WiFi without needing a hub. It’s small, waterproof, and very sensitive—I tested it with just a few drops of water and it triggered instantly. The 100dB alarm is loud enough to hear from another room, and the app alerts are a great backup if I’m away from home.I use mine near the water heater, and it gives me peace of mind knowing I’ll get notified right away if there’s a leak. A solid, affordable choice for protecting your home from water damage.

Works great with Home Assistant and Shelly bluetooth switches
If you have Home Assistant for home automation and need some leak sensors these work great (as of the 2025.01 release of Home Assistant). But you need to understand how they work1) They only work over bluetooth. This is good, keeps the battery life long2) You need some whole house bluetooth receivers. If you happen to have shelly devices with the bluetooth capability (Like the plus series) then you’re all set. Because Home Assistant can configure the shelly switches to listen and pickup bluetooth signals from all over the house.If you have these things, then setup is easy. Pop the included AAA batteries in, check Home Assistant and it will say it detected a Switchbot Leak Detector. Click “Yes, set it up” and you’re done (but give it a better name). Shows up with the proper icon (water drop) and type (moisture).Now the real fun is the automation. I have a zwave whole house water shutoff device. It will turn the quarter turn valve on my incoming water line to my house. I grouped all my leak detectors and created an automation that says “If the group (IE any one of the group) detects water then shut off the whole house water valve”. Tested it out and within 1-2 seconds of a water drop the valve is turning off. It also sends me a notification too.The sensors themselves are very sensitive. The top is dished a little so if a single drop of water hits the top it will likely set it off. The bottom contacts are pretty sensitive too but would take a very small puddle just due to how the sensor is on the bottom and water spreads.They do have an alarm too, it’s not super loud, but it will get your attention if you’re in the same room. Mostly though I bought them for the Home Assistant integration. There are cheaper sensors if you just want an alarm when water hits them.Water damage is the worst thing for a house, and also the most likely. Toilets, sinks, washing machine, water heater, anything with water should have a sensor next to it and ideally some automation to cut the water. In 20 years of home ownership I’ve only had 2 major issues and both were water related (water heater once, washing machine second). I’m all prepared to never have another one (fingers crossed!) I have 12 of these spread out around my house.

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!

Great product with remote notification capability
I have been looking for a water leak detector for a while. Most other products I found do not have wifi connectivity and wont be knowing if a leak happens when I am not at home. This is very important for Texas weather as homes here arent built for cold weather and recently temps dropping to the point of pipes getting frozen and broken. Having an ability to detect these leaks, at least at a specific location when we are not at home and get a notification on phone is a nice feature to have.Set up was breeze. Linking the devices with rest of switchbot ecosystem is easy and its working as intended.Overall I am very satisfied with this product and its functionality.

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!

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.

Ich habe den SwitchBot WLAN Wassermelder für den Keller gekauft, um frühzeitig auf mögliche Wasserschäden reagieren zu können – und bin absolut zufrieden!Installation:Die Einrichtung war super einfach – kein Hub nötig, einfach per 2,4 GHz WLAN mit der App verbinden. Die App führt einen schrittweise durch den Prozess, der in wenigen Minuten erledigt ist.Funktion:Der Alarm ist mit seinen 100 dB richtig laut – definitiv nicht zu überhören! Zusätzlich erhält man sofort eine Push-Benachrichtigung aufs Handy, was besonders praktisch ist, wenn man gerade nicht zu Hause ist. Ich habe einen kurzen Test mit Wasser gemacht – die Reaktion war blitzschnell.Design & Verarbeitung:Das Gerät ist kompakt, sauber verarbeitet und durch IP67 auch komplett wasserdicht. Die kleinen Standfüße sorgen dafür, dass auch minimale Mengen Wasser schnell erkannt werden.Besonders gut gefällt mir:Keine zusätzliche Bridge oder Hub erforderlichFlexibel platzierbar (z. B. unter Waschmaschine, Spüle oder im Technikraum)App ist übersichtlich und leicht zu bedienenFazit:Ein Muss für alle, die sich vor teuren Wasserschäden schützen wollen – besonders in sensiblen Bereichen wie Küche, Bad oder Keller. Preis-Leistung top!
