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

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!

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 work 1) They only work over bluetooth. This is good, keeps the battery life long 2) 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.

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

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!

Purchased these back in September and placed them in the strategic spots I was concerned about. These were very easy to set up, and to be honest, I forgot all about them until today! These one under the front load washer stayed to squawk not long after I started a load of laundry. Admittedly, I was turning off the washer wondering why IT was making that noise, the. I noticed the small puddle of water on the floor. Something was plugging the drain in the gasket and/or into trapped something in the door unknowingly. Whatever it was sure proved to me these alarms do their job!

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.

Setup is very easy.

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!

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.

El SwitchBot WiFi Sensor de Agua es un dispositivo inteligente que cumple perfectamente con su función. Ya tengo detectores de otras marcas en la cocina, junto a la lavadora y el lavavajillas, pero me decidí por este modelo porque SwitchBot está destacando en el sector. Su aplicación es intuitiva y permite una configuración rápida, además de utilizar un tipo de pila accesible. Lo más importante para mí era que emitiera una alarma potente en caso de detectar agua, y lo hace de forma impecable con un sonido ajustable. Lo he instalado junto al desagüe del aire acondicionado, ya que en ocasiones se emboza, y la tranquilidad que aporta es inigualable. Además, su certificación IP67 garantiza resistencia al agua, y el hecho de que no necesite un hub simplifica mucho su uso. Sin duda, una compra recomendable para proteger cualquier espacio de posibles fugas.

Tras varios meses de uso he de indicar mi total satisfacción con el producto. Compré un pack de tres tras haber probado el producto individualmente. Los tengo distribuidos por la cocina, baños y lavadero, de tal forma que me permite detectar cualquier fuga de agua antes de que provoque un problema grave. Especial mención cebo hacer del sensor que coloque junto a la toma de agua de la nevera americana, gracias a lo que me di cuenta de una ligera perdida en el conducto plástico, que de haberse rodo habría provocado un escape grande. Indicar que además del pitido que emite el propio sensor, los tengo vinculados con mi aplicación Alexa, que me permite recibir una aviso de alarma a través los altavoces , además de la notificación al móvil que tengo configurado en la propia app de Switchbot. Por todo ello debo indicar que el producto es totalmente recomendable.

Brilliant ! I have installed cameras, door devices, routers, temp guages in 2 locations, and this is the only device of the bunch that just works, No complexity, very reasonable, and part of what gives a small discount from insurers. The fact that it does not need a router makes it much more fail resistant. If I get a water leak, I get a notification and an email. If the battery goes low, I get notifications(and they aren't supposed to be hard on batteries). If I go away for a while, I can see battery state on app. I'm rarely this enthused about a product.

Facile à installer avec l’application sur mon iPhone. Les notifications sont bien envoyées lors d’un test d’immersion
