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

Aqara as always offers great smart devices compatibility with all major ecosystem. These water leak sensors maintain a connection consistently to hub. And work great with the slightest bit of water I get a notification. They are compact in size and can be placed anywhere. I love that they are slim enough to slide under washer machine and refrigerator. Very easy to pair. Only downside is they are expensive. But that’s everything nowadays and in no part changes my opinion of the great product.

This water detector didn't quite work how I expected, I wanted to use it to detect when I turn on the shower, but that's not what it's designed for, that was mostly my own user error, though! The sensor actually works perfectly for actual water leaks, detecting even a single drop right away, it totally fulfills its purpose as a leak detector, just keep in mind it's not the right tool if you plan to use it inside a shower like I did

Update - 11-29-2023: Added temperature sensor info below and attached image. Original Review: Bought these since they were on sale and wanted something to integrate to Home Assistant. Wasn't super on board with the idea of a "coin" style water detector (would prefer the cable type), but went with this to give it a shot. I put it next to the drain and water heater downstairs. Fast forward three months. We had a small backup in our drain downstairs and the alarm in Home Assistant went off. Saved me a lot of damage I'm sure. You will 100% want to make sure you set up multiple critical notifications in your automation and consider choosing a custom obnoxious sound. If you're sleeping, you want to make sure you don't sleep through it. The Good: -- Paid for itself already -- Integrated very nicely with my Sonoff receiver in Home Assistant. -- Fairly non-descript and small. Hard to notice on the floor. -- Fast. This thing went off immediately when water had reached it. -- Inexpensive! I'll be honest, I really wish there was a cable type Zigbee detector that wasn't $100. But this thing is just so darn inexpensive that you can get six of these for the cost of one of those plus an extension cable. The Cromulent: -- It's battery-powered. As mentioned above, I the cable type is preferred, but I'm guessing there's zero chance of a cable type without having to be plugged into an outlet. Plus you can put these wherever you need without having to worry about an outlet. -- TBD on battery life so far. I've been tracking this since I installed it in mid-July. Started at 88% with the factory-supplied battery (constant problem with Aqara) and within ten days it had dropped to 70%. It has been sitting there at 70% for three months now. I'll update this when I have to change batteries. -- The LQI shows a fairly weak connection, which is surprising given that it's only 10-15 feet away through two interior walls. Kind of surprising given that other devices that are much further away are significantly better. The Bad: -- The temperature sensors in these are utter garbage. They're the internal temperature of the device, not the room they're in. They're off by 10+ degF and should NOT be relied upon in any capacity. Overall: There really are no major primary weaknesses to this device. I'll be grabbing a couple more when they go on sale to scatter around the house. I'd like to get the Eve Water Guard but at $100 + $20/6 ft, it's really hard to justify it. The temperature sensors are useless cost adders and Aqara would be better off just removing them.

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.

Starting with the good: As a leak detection sensor it did the job well. I tested it in a simulated leak and worked beautifully within a second from contacting water. Pairing with the hub and with HomeKit was a breeze. Once connected, the connection was very stable and didn’t have any “no response” flags. The range is also pretty good. In a 4000 sq ft house, I was able to place the hub in one end and the sensor all the way on the other side without any issues. Now why do I not recommend it? I placed the sensor in the attic under a recently repaired roof spot to get alerts if it leaks again. When it rained heavy, my roof repair did not hold up and some water found it’s way inside the attic. The Aqara sensor did what it’s supposed to do and detected the leak - five stars so far! - . However, a few minutes later it stopped responding. I went up there to check and didn’t see anything on the outside. I then wiped it clean and opened the battery compartment and looks like the water leaked everywhere inside the sensor and fried the board and battery. Upon more inspection it looks like the point of entry was due to a nicked O-ring that was supposed to prevent water from getting inside the sensor as shown in attached picture. This usually happens with poor manufacturing QC. I would have otherwise given this sensor 5 stars but with such poor manufacturing tolerance and quality control it makes the sensor potentially a one-time use and not worth spending >$20 on. I have 3 other sensors that have not detected any leaks yet. It remains to be seen how many of them could have the same o-ring issue and will die after one leak. Will update with more info later.

I have these under every sink, under the dishwasher, near water heater, under washing machine, and under well pump. They're connected to Home Assistant, which in turn activates the Aqara water shut-offs if these things detect the leak. Very easy to use as standalone with just the Aqara app if need be.

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.

I purchased this just to see if it would work with SmartThings with the new edge drivers even though Aqara says they do not support it. It works. I've only had it connected for about a week, but so far no issues. I first tried to pair the device without installing any custom drivers. It would pair but only as "device" with no functionality. I finally installed a custom driver, paired again and, boom, there it was. You will need to do an internet search for the driver, accept the invitation, and then install the edge driver for the Water Leak Sensor. I then paired the device by scanning for new devices, but I think you could also do the "add device by brand" process. The top of the device really is a button. Don't be shy about pushing down on it. After pairing, you will need to press the top button for one second to do a range test. That will perform the initial communication with SmartThings. After that, you should be good to go. If you see a message about "this device has not updated", do the range test again. Some people have reported issues with the device losing communication with SmartThings and dropping off the network. I have not had that issue yet. I will update the review if I do.

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

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 compatto Pregi: 1. Affidabilità impeccabile nel tempo Dopo 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 stato Questo 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 facilissima Non 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 discrezione Il 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 eccellente Funziona 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'acqua 5. Impermeabilità certificata IP67 Può essere tranquillamente esposto ad acqua e umidità. In caso di allagamento, continua a comunicare senza problemi. Difetti 1. Nessun test manuale integrato Non 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 integrato Il 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 feedback Il 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 1.2 Pur 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. Conclusioni Il 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 tempo Facilità di installazione Design compatto e impermeabile Ottima integrazione in domotica Contro: Nessun allarme sonoro integrato Protocollo Zigbee 1.2 Manca un test di autodiagnostica Si, lo consiglierei ad occhi chiusi ad amici e parenti
