Easy to set up and add to Aqara app and Apple HomeKit. Have a couple of these now (under the kitchen sink, boiler cupboard, ensuite). Very cheap for the peace of mind they give.

4.0 out of 5 stars Great addition to add for your smart home

J. · 22 January 2023

I have been using the Aqara Water Leak Sensor for a few months now and I have to say, I am extremely impressed with its performance. This sensor is designed to detect water leaks and alert you immediately, which can help prevent costly water damage.The installation process was very easy, it comes with a double-sided adhesive tape which I used to stick it to the floor near any potential water leaks, such as under the sink, near the washing machine, etc. It also comes with a CR2450 battery that lasts for about two years.One of the things I appreciate the most about this sensor is its sensitivity, it can detect even the smallest amount of water and sends an alert to my smartphone through the Aqara app. I have set it up to send notifications to my phone and it has worked flawlessly, I have received alerts even when the water leak was very small.I also like that it is compatible with other smart home devices, such as my smart plugs, and I can set up automations to turn off the water supply when it detects a leak. This feature gives me peace of mind knowing that even if I am not home, my smart devices will act on it.Overall, I think the Aqara Water Leak Sensor is an excellent investment for anyone looking to prevent water damage in their home. It is easy to install, extremely sensitive, and can be integrated with other smart home devices. I highly recommend it to anyone looking for a reliable water leak sensor.

5.0 out of 5 stars Home Assistant Bed presence sensor!

L.L. · 8 January 2024

I purchased this to make a bed presence sensor using it along with a pressure sensor mat. This was very easy to setup and incorporate within Home Assistant.It was just a case of wiring two wires from the mat to the screws on the bottom of this sensor and the sensor was detected within HA without using an Aqara Hub - it's a Zigbee device and I have a Zigbee dongle so had no additional hub required. Once added in HA, I configured it as an on/off switch rather than a water sensor. There's a few readily available guides for setting it up this way.I've been using it for a couple of months now without any problem at all, it's super reliable and also the battery is still at 77%.I've no idea how well this works as a water/leak sensor but for my use case it's great and anyone else wanting to try setting it up as a bed presence sensor in HA and be able to create automations based on whether your in bed or not, it's great - recommended.

5.0 out of 5 stars Reassuring water leak detector

r. · 25 August 2024

I got a couple of these to go under sinks after a recent water leak. They're nice and small and will sit discreetly at the back of a cupboard.The information suggests pairing with an aqara hub, but as they're zigbee devices, they also pair with my sonoff zigbee dongle plus. Using ZHA they expose moisture (wet or dry), device temp (as expected, this runs hotter than ambient temperature) , firmware and battery. The battery showed 84% immediately, then rapidly 73% - this is something I've noticed with some of my other aqara zigbee devices, although the battery then seems to stay very stable at that level for a long time.The first time I tried to pair the device was unsuccessful. A 5 second press of the reset button didn't seem to make if visible to my zigbee network. The second time, I bought it close to my zigbee dongle, and held the reset button until the blue light flashed, and continued to hold the button until it paired with ZHA - this took approximately 20 seconds.In a crude test I poured about 10 ml of water next to the device and let it trickly underneath - it took about a minute, but then triggered my leak detection automation. I think it took some time for the water to spread and get in contact with the 2 sensors which are underneath the device. When I remove it from the water, it immediately records dry. When I placed it back in the small 10ml pool of water on the surface, it immediately recorded wet again.I'm pretty happy that this will rapidly detect a fairly small leak.

Aqara make quality zigbee products. I setup this with a none apart hub with no glitches or issue.

5.0 out of 5 stars Works like advertised, easy to install

E.S. · 6 October 2024

It was easy to install on my Home Assistant.Works as tested, no problems.

Fait bien son travail.

G. · 7 March 2025

J'ai fait l’acquisition de ce détecteur de fuite car j'en possède déjà un depuis un peu plus de 6 ans, il fait très bien son travail, placé en dessous de l'évacuation de la machine à laver où il y a parfois des débordements nous sommes tout de suite prévenus via sirène sur le hub et notifications push. Nécessite au minimum un hub aqara, la pile sur le premier est toujours celle d'origine.

Ottimo sensore rilevazione perdita acqua

m. · 6 July 2025

Il sensore di perdite d'acqua Aqara SJCGQ11LM è un dispositivo Zigbee progettato per rilevare la presenza di acqua in ambienti domestici o professionali e segnalare tempestivamente eventuali perdite, allagamenti o infiltrazioni. È compatibile con l'ecosistema Aqara Home, Apple HomeKit, Home Assistant (tramite Zigbee2MQTT o ZHA) e altre piattaforme compatibili con Zigbee.Caratteristiche principali:- Protocollo di comunicazione: Zigbee (Zigbee 1.2)- Alimentazione: CR2032 (sostituibile)- Classe di protezione: IP67 (resistente a polvere e immersione temporanea)- Rilevamento tramite due pin metallici alla base- Design compattoPregi:1. Affidabilità impeccabile nel tempoDopo oltre un anno di utilizzo continuo, il sensore si è dimostrato estremamente affidabile: Zero falsi allarmi, Nessuna perdita di comunicazione Zigbee, Batteria ancora in buono statoQuesto è uno degli aspetti più importanti per un sensore di sicurezza: non solo deve funzionare, ma deve farlo sempre. Questo Aqara lo fa egregiamente.2. Installazione facilissimaNon richiede alcuna configurazione complicata. Basta accoppiarlo al coordinatore Zigbee tramite premendo sul simbolo "goccia", posizionarlo nel punto desiderato (es. sotto lavandini, vicino alla lavatrice o alla caldaia) e dimenticarsene. Funziona da subito.3. Compattezza e discrezioneIl design minimale e le dimensioni ridotte permettono di posizionarlo ovunque senza intralcio. Non ha cavi, è leggerissimo e può essere messo anche sotto mobili bassi.4. Compatibilità eccellenteFunziona perfettamente con Home Assistant, sia con ZHA che con Zigbee2MQTT, e di conseguenza può essere integrato in automazioni avanzate, come: Notifiche istantanee, attivazione sirene, chiusura automatica dell'elettrovalvola dell'acqua5. Impermeabilità certificata IP67Può essere tranquillamente esposto ad acqua e umidità. In caso di allagamento, continua a comunicare senza problemi.Difetti1. Nessun test manuale integratoNon c’è un pulsante di “test allarme”. Per testarlo, bisogna fisicamente bagnare i due elettrodi. Una funzione di test sarebbe comoda per verificare periodicamente il corretto funzionamento.2. Manca un allarme acustico integratoIl dispositivo non emette alcun suono: in caso di allarme, serve un sistema domotico per notificare l’utente o attivare un avvisatore esterno. Se viene usato in modo standalone, non segnala nulla da solo.3. Comunicazione unidirezionale e senza feedbackIl sensore non invia aggiornamenti regolari se non rileva cambiamenti (non invia heartbeat frequenti come altri sensori). Anche se ciò contribuisce a prolungare la durata della batteria, può creare incertezza sul suo stato di salute se non monitorato correttamente.4. Versione Zigbee 1.2Pur funzionando benissimo, il supporto al protocollo Zigbee 3.0 (presente nei modelli più recenti Aqara) garantisce interoperabilità e aggiornamenti futuri migliori. Questo modello resta comunque molto valido, ma è tecnicamente meno moderno.Batteria: Dopo oltre 12 mesi di utilizzo la batteria non è ancora da sostituire, anzi segna 70%Questo conferma la bassissima richiesta energetica del dispositivo.ConclusioniIl sensore di perdite d'acqua Aqara SJCGQ11LM è una scelta eccellente per chi cerca un dispositivo semplice, affidabile e integrabile in un sistema domotico. Dopo oltre un anno di utilizzo, si è dimostrato totalmente privo di problemi: mai una disconnessione, mai un falso positivo, mai un segnale mancato.Consigliato soprattutto se hai un ecosistema Zigbee già funzionante. È il tipo di sensore “installalo e dimenticalo” che dà sicurezza reale, senza bisogno di manutenzione frequente.Pro:Funzionamento impeccabile nel tempoFacilità di installazioneDesign compatto e impermeabileOttima integrazione in domoticaContro:Nessun allarme sonoro integratoProtocollo Zigbee 1.2Manca un test di autodiagnosticaSi, lo consiglierei ad occhi chiusi ad amici e parenti

Homekit fähig ohne zusätzliche Herstellerapp

S. · 9 October 2024

Ich wollte meine Homekit basierte smarthome Landschaft um die sinnvolle Funktion „Wasserpfützen entdecken und melden“ ergänzen. Der aqara Sensor in Verbindung mit dem aqara M2 Hub ist für mich die beste Lösung. Allerdings mit Umgehung des vom Hersteller empfohlenen Installationsverfahrens 😉Meine Bedingungen waren- zuverlässige Meldung direkt in der apple home app- kein account/Cloudspeicher beim Hersteller (der icloud vertraue ich meine Daten an, den unzähligen Herstellern, die kommen und gehen nicht 🤨)- möglichst keine weitere App- kein automatischer akkustischer Signalton (Horrorszenario: bei Alarm in Abwesenheit alarmieren die Nachbarn die Feuerwehr, Türöffnung, … nein danke 🫣)Auswahlverfahren:Es gibt einen schicken Sensor von eve, der darauf ausgelegt ist, ausschließlich über homekit installiert und betrieben zu werden. Design und Konzept überzeugen, aber der Sensor hat eine interne 100db laute Sirene, die sich nicht dauerhaft stumm schalten lässt. Fällt leider weg, sonst wäre das mein Favorit geworden.Weitere Melder benötigen zwingend eine Bridge/Hub des jeweiligen Herstellers und wollen dazu zwingend eine eigene App, die wiederum ein Benutzerkonto und eine Cloudlösung des Herstellers erfordern. Will ich nicht.Die Lösung mit aqara benötigt ebenfalls eine bridge von aqara, aber die Installation ist auch direkt (!) über die apple home App möglich. Bridge und Sensoren sind bei aqara zudem sehr günstig! aqara gewinnt: aqara M2 hub (=bridge) und 3 Sensoren gekauft!Der Trick mit der Installation 😎(nicht von mir sondern von freundlichen Internetbloggern entdeckt)M2 hub am Strom anschließen, eine blecherne Stimme informiert nach einigen Sekunden, dass das Gerät im Kopplungsmodus ist. Home app öffnen und mit + Gerät hinzufügen (QR code scannen). Damit ist der M2 eingebunden.Knopf am M2 drei Mal drücken. Blechmadame informiert, dass nun Sensoren an den M2 angebunden werden können. Sensor auf stabile Unterlage stellen und 5 Sekunden auf das Symbol des Wassertropfens drücken (darunter versteckt sich ein Druckschalter). Fertig 🤗Mit dieser Lösung verzichtet man auf die vielen weiteren Möglichkeiten des M2. Der kann weit mehr als Sensordaten an apple Home weiterzuleiten, das geht dann aber wirklich nur mit der aqara App.Jetzt zum Sensor selbst:Das Teil ist winzig!!! Passt aber damit wirklich unter so ziemlich alles, was Wasser verlieren kann. Strom kommt aus einer handelsüblichen CR2032 Knopfzelle, die 2 Jahre halten soll und die einfach wechselbar ist.Der Sensor fühlt sich sehr gut verarbeitet an, sieht mit der leicht glänzenden Oberfläche gut aus und ist darüber hinaus nach IP67 wasserresistent.Der Test:macht Spaß 😄kleine Wasserpfütze produzieren, Sensor rein und keine 5 Sekunden später schlägt die home App Alarm und auch nur diese!Die Reichweite des genutzten Funkstandards Sensor - M2 Hub hat Grenzen: 1 Stockwerk und normale Zimmertür dazwischen geht, Metalltür geht nicht. Gemäß aqara soll der M2 Hub zudem nicht mehr als ca. 5m vom Router entfernt stehen, ich denke dass abhängig von Router und Repeater/Mesh-Zusammenstellung mehr geht.Mein Fazit:Zwar lässt sich das zusätzliche Zwischengerät M2 Hub nicht vermeiden, aber die so erstellte Lösung funktioniert zuverlässig, ist sehr günstig in der Anschaffung und verteilt meine Daten nicht im Netz. Und die Komponenten sehen hochwertig aus.Ich kann den Sensor und den M2 mit gutem Gewissen empfehlen ☺️

Very happy with this

Excellent! It does what is supposed to be doing, and it also gives me a graph of temperature over time during the day.

Hides in its place, working as it should
