Aqara Water Leak Sensor 3 Pack, Zigbee Water Leak Detector for Alarm System

Very happy with these sensors! They're surprisingly small, which makes placement easy in tight spots like under sinks and behind the washing machine. Connected directly to my Home Assistant hub without any issues, setup was straightforward. The Zigbee connection is stable and responsive. Having peace of mind knowing I'll get alerts if there's a leak is worth every penny. If you're running Home Assistant and need water leak detection, these are excellent. Highly recommend the 3-pack for covering multiple areas.

I am using 3 of these with an Aqara M3 Hub. The M3 (which I would highly recommend) has a built in speaker for alarms. Adding the leak sensor to the Hub was easy and took only seconds. The Aqara phone app offered to automatically create an alarm for them. I tested them by wetting my hand and pressing them into my hand, they each immediately notified of a leak via the M3 Hub's audio alarm. They have two exposed metal screws on the back whihc sense water using an electrical signal between the screws. I beieve they would signal a leak if you had aproximately 1 mm of water, so not much. They do need to be placed flat on the surface you want to monitor. I put them in some corners of my basement where water has got in previously. I used these under Home Assitant as well (they work great with Zigbee2MQTT), but decided I liked the Aqara ecosystem features better. Either method of control works well, depending on your preference. Note that you compress the dome of the sensor to push the pairing "button". And a blue LED will blink through the dome. It's not totally obvious to do this.

Setup was a snap, and I did a test with a dampened paper towel. It triggered right away, and ceased triggering when dried off. UPDATE: I bought 6 more (two 3-packs). Of those six, three took several tries to pair although my Hubitat C-8 hub is only about 25 feet (7.6 meters) from the computer I am using to access the pairing screen. Two more said they paired, but stuck on "Initializing", and then timed out. I did all of the recommended troubleshooting, including try fresh, name-brand batteries. I am returning all seven and will try something else.

These provide peace of mind! If you own a home and want to ensure you are notified in the event of a leak to avoid costly repairs are mold damage from a slow leak, these are your best friend. They were easy to set up, but you'll need a Aqara hub (I bought the Aqara Smart Hub M100) to be able to connect them to anything. I connected them to Apple HomeKit within a few seconds once it was hooked up. I think these are a great value and significantly cheaper than a repair. I tested them and they worked perfectly at even a small amount of dampness. I feel confident these will notify me immediately to any potential water leak and plan to buy more.

Sensor detected water, but after 5-6 months 2 of 3 sensors stopped communicating with my Zigbee network. I had to put the devices into pairing mode and search for them again. This shouldn't happen. Having to re-pair the Zigbee device

The Aqara Water Leak Sensor Kit is an absolute game-changer for home safety and peace of mind. If you’ve ever worried about water damage from leaks, this kit is the perfect solution. The sensors are incredibly compact and easy to set up. I placed them under my kitchen sink, near the washing machine, and in the basement, and they instantly connected to my Aqara Hub without any issues. What impressed me most is their sensitivity—just a few drops of water are enough to trigger an alert. The integration with my smart home system is seamless. Through the Aqara app and Apple HomeKit, I receive real-time notifications on my phone whenever water is detected. The automation features are fantastic, too—I set it up so that the smart valve shuts off the water supply automatically in case of a leak. The build quality is excellent, and the sensors are designed to be long-lasting. I also appreciate that the battery life is impressive, meaning I won’t need to worry about frequent replacements. Overall, the Aqara Water Leak Sensor Kit is a must-have for any homeowner. It provides a sense of security knowing your home is protected from potential water damage. Highly recommend!

I think Aqara is missing the mark. They claim to be Zigbee connection, but from what I read, if you don't use an Aqara hub, you will have connection issues. I did get the units to connect with Home Assistant, but they would disconnect while moving them around. So, I bought a Aqara Zigbee coordinator (hub). Just to find out it won't work with Home Assistant if you don't have a HomeKit hub. Well I don't use Apple products and refuse to pay for their overprice products. So, I gave up and I am sending all the Aqara products back. Never to buy Aqara again. I will have to say, everything I have seen of Aqara is decent quality. And was easy to use, but if it doesn't connect to Home Assistant directly, I don't want it.

I have 4 of these scattered around under sinks/fridge/chest freezer/laundry room currently, after having an initial one that I used for over a year. Batteries last for ages, no complaint there. They feel of decent quality, and held up to a dog chewing on one. I have them paired into my home assistant automations, and connected to my zigbee network (I do not use Aqara hubs, nor would I), and they wake fast when wet and let me fire a notification to my phone/announce in the house/and shut off the water main all within 1 second of water touching their contacts.

Trouble freee litter sensor, save my floor 2 time, works very well with my Aqura home security system.

Ce configure rapidement grâce à l’application. Capteur fiable. Batterie impressionnante. Plus d’un an autonomie.

Questo piccolo sensore d'acqua di Aqara è uno di quei dispositivi che costano poco ma che possono letteralmente salvarvi da migliaia di euro di danni da allagamento. È compatto, discreto e fa esattamente ciò che promette con una precisione chirurgica. ​Ecco i motivi per cui ne ho piazzati diversi nei punti critici della casa: ​Dimensioni e Posizionamento: È incredibilmente piccolo e sottile ,Questo permette di nasconderlo ovunque senza che si noti: sotto la lavatrice, sotto il lavandino della cucina ecc ​Precisione e Contatti in Oro: Sulla parte inferiore ha due sonde con viti placcate in oro. Non appena il livello dell'acqua raggiunge appena 0,5 mm e unisce i due contatti, il sensore scatta all'istante. Non perde un colpo ed è sensibilissimo. ​Integrazione Domotica e Notifiche istantanee: Grazie al protocollo Zigbee, il consumo di batteria è ridicolo (dura anni con una singola pila a bottone CR2032) e la reattività è fulminea. Tramite il bridge si espone magnificamente via Matter sia su Google Home che su Home Assistant. Essendo un'integrazione locale, l'automazione è immediata: nel momento esatto in cui tocca l'acqua, ricevo la notifica push critica sullo smartphone e partono le scene domotiche (come far lampeggiare le luci di rosso o attivare un avviso sonoro). ​Impermeabilità IP67: Il sensore è completamente sigillato e certificato IP67 contro polvere e acqua. Significa che può rimanere letteralmente sommerso dall'acqua durante un principio di allagamento senza rovinarsi, continuando a trasmettere il segnale. ​Materiali e Qualità: Nonostante il prezzo super accessibile, la plastica è robusta e ben rifinita, in pieno stile Aqara. ​In conclusione: Un dispositivo "configura e dimentica" che offre una tranquillità impagabile, specialmente quando si è fuori casa o in vacanza. Per chiunque abbia un sistema domotico basato su Matter o Home Assistant, l'acquisto di questi sensori d'acqua è una scelta obbligata per la prevenzione. Consigliatissimo!

Seid Jahren im Einsatz mit Homeassistant. Fällen bei mir nicht aus dem Zigbee Netzwerk, Batterie hält gefühlt ewig. Einer überwacht den Wasserstand in der Kaffeemaschine mit Hilfe von zwei Drähten und obwohl die dauerhaft im Wasser hängen hält die Batterie trotzdem gefühlt nicht kürzer. Meldung erfolgt nach ca. 1 Sekunde, auch wenn das Gerät vorher monatelang nicht angefasst wurde. Ich wünschte alle Zigbee Geräte wären so zuverlässig.

Producto Aqara, creo que hay poco mas que decir. Bien terminado y funciona correctamente. Como punto negativo que las baterías vienen conectadas y por lo tanto algo gastadas, no están al 100% como era de esperar.
