SwitchBot 3 Pack Water Leak Detector for Home, Water Leak Sensor, No Hub

The SwitchBot WiFi Water Sensor is one of those devices you hope you never need—but you’ll be really glad you have it. Setup is quick, especially if you're already in the SwitchBot ecosystem. It connects over Wi-Fi or Bluetooth, so there’s no separate hub necessary to fuss with, and alerts hit your phone fast when water is detected. I would encourage anyone to connect it to their existing hub if possible. Switchbot has a lot of them (some even built into other smart devices) and I have mine included with not only Switchbot's hub but my Homey Pro. The sensor itself is small and easy to tuck under sinks, behind toilets, near water heaters, or by washing machines. Sensitivity is good—it can catch even small leaks before they turn into expensive disasters. The app notifications are loud and clear, and you can also tie it into automations (like turning off smart plugs or triggering other devices). Mine is under my kitchen sink where I've already had an issue and was kicking myself for not already having this device. Trust me it's very inexpensive for peace of mind!

These come with very easy to read instructions. (Written by an English speaking writer). The directions are clear, concise and the monitors are easy to set up and test. They come with batteries. I tested with a semi-damp paper towel prior to putting them in their final position and they alarmed (you can control the loudness - most other sensors you cannot) and sent an alert to my phone. They can sense if the liquid is coming from under the sensor or dripping on top of the sensor. I am very pleased with this product. As side note, you can purchase separately a device that can turn off the water in your house. I may get that at a later time.

Works perfectly. Easy to set up. Would be five stars if you did not have to reset all the sensors if wi-fi goes down!

This little device saved me from floor damage and is not that expensive .. i bought this sensor, since i have no pan on my ac. i was driving when i kept getting leak detection constantly. I drove home and found out that the ac was clog.. this device is awesome for alerting me so fast.. 5 stars for .!!⭐️⭐️⭐️⭐️⭐️

I have setup ten of the Switchbot water sensors recently, with no glitches in any of them during install! Quick and clean using the Switchbot app, and better yet, the ultimate prize: Alexa recognized all Switchbot sensors almost immediately. Now if there is a leak behind the fridge, Alexa will tell me, through out the house, "check for water behind the fridge"! I used to be a mostly Smartthings house, but after the Bose fiasco, I couldn't get any speakers to work with Smartthings. The Echo Dot Max is a really smart speaker. And Switchbot was recommended to me for an Alexa smart home. You need to use the Alexa Skills for Switchbot. That took me a bit to figure out, but it works. Seriously, decent moisture sensors do work; last year I got a notification that it was wet underneath my tankless water heater. I thought that odd but I checked. Sure enough, some small connection came loose. And I caught it within minutes! One paper towel, and a call to the plumber! The water heater is in an indoor utility room; I would have had serious damage if I hadn't had the early warning from a moisture sensor underneath. Now I have a Switchbot water sensor under every faucet and valve in the house, and they're all programmed for both audio and text notifications through Alexa. That's a nice peace of mind...

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.

The units appear to be well built and were easy to get configured in the app. They have all tested successfully. Hoping they're never needed but we have peace of mind with them installed.

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

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!

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.

Qualidade ótima e muito fácil de instalar

Ayer recibí el producto muy bien embalado incluye pilas que se ven en el video y una pua para abrir la tapa que va un poco dura para asi conseguir que se estanco. El funcionamiento es muy simple tienes 2 pines arriba y otros 2 abajo que al notar que cierran el circuito disparan la alarma. La vinculación con la aplicación de switchbot a sido casi inmediata simplemente aprietas durante 2 segundo el único botón del dispositivo y ya vincula siguiendo los pasos de la app. Conectas a la wifi crea el equipo pones las credenciales de la wifi de tu casa y a disfrutar. La app es muy clara incluso tienen un punto muy original y deja que lo configuremos para que salte la alarma cuando no detecta agua, ideal para acuarios o sistemas de riego. Las notificaciones me llagan a la perfección a mi smartphone y smartwatch además al añadirlo a la app ya me sale en mi ecosistema de Google home sin problemas. Creo que es un muy buen producto y mas por el precio que tiene.

J'ai déjà plusieurs thermomètres switchbot dont je suis très content. Ce capteur de fuite parait solide et semble bien marcher suivant mes tests, avec une détection sur le support et au dessus (pour détecter un goutte à goutte avant qu'il y ai une flaque au sol).
