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.

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

Works without a hub.
I wanted to be notified if there is water in my basement when I am away at work. The SwitchBot is great. No need for a hub. It sends a notice to the SwitchBot app on your phone from the wifi at your house. The water sensor looks to be quality built. And the price is right!

This is a no-brainer!
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!

Water warning system
Great product! Use it as water leak protection warning system for my tankless water heater! Easy to setup and install!

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!

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.

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!

“installé” ( juste posé) dans ma cave sous la tuyauterie de la maison.. il m’a déjà sauvé une fois de gros dégâts en m’alertant pendant que j’étais au travail d’une fuite d’eau d’un raccord qu’il a capté de part le premier niveau du capteur ( humidité) (au delà de qq mm l’autre capteur un peu plus haut alerte aussi de fuite plus importante ) j’ai crée une automatisation pour une alerte claire qui est relayée par wifi. j’ai fait aussi un essais sur place avec l’alarme qui en position forte réveille bien… enfin je “l’emprunte” parfois lorsque je pompe les cuves l’été pour être averti quand plein ( déborde) . très pratique !

観賞魚水槽でインラインヒーターやCO2ユニットを使っており万一に備えて深めのトレイを敷いているがトラブルがあった際に携帯へすぐにアラートが飛んできてほしいので設置しました。また、半地下潜った場所にあるピットで冠水した際の警報としても使えるように追加設置しました。感度良好で良い製品です。
