Aqara Water Leak Sensor 1 Pack, Zigbee Water Leak Detector for Alarm System

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.

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!

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.

So far works good and the battery life is fine. My only minor issue is it tends to go off line for periods but it seems to be the Aqara hub itself rather than an issue with the sensor itself.

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.

We loved them while they worked, but 9 out of 14 purchases failed after barely over a year. Only 3 door sensors and 1 temp sensor are still working today. Multiple battery swaps and reset attempts have failed, and customer service has declined to replace. Door sensors (3/8 still work) were the most reliable. They literally never had to be re-paired even once (while they worked) and had excellent battery life. Nice small form factor. Whether it's a front door opening/closing multiple times a day or a window that was only opened once every few months, they worked flawlessly (until they didn't). Temp sensors (1/4 still work), need to be re-paired every so often and drain batteries much faster (which seems fair - they have a lot more work to do than a binary door/window sensor). I would prefer if they were made thicker/larger to support a larger battery. Leak detectors (0/2 still work) all failed within a few months and were the biggest pain to set up. You'd think they came from a totally different manufacturer or something. They were massively annoying to pair and re-pair, and they had to be re-paired ALL the time. Saddest thing is that customer support is not willing to replace out-of-warranty. Partly on us for not bothering to RMA for a long time, I guess. We'll be checking out other brands to replace the dead units before we consider Aqara again.

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.

Two of the three sensors have been rock solid. The third will not stay connected. New battery made no difference. I reached out to Aqara and they basically asked a lot of questions in order to tell me to go pound sand because I'm using them with home assistant and not the native hub and app.

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

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. Durée de vie environ sept ans pour le premier en service qui donnait constamment des faux positifs après une mise à jour de l'appli ( je ne sais pas si il y a un lien ). J'en ai acheté un autre.

In the realm of home automation and smart living, the Aqara Water Leak Sensor stands as a beacon of reliability and peace of mind. Paired seamlessly with my home assistant via Zigbee2MQTT, this little device has become an indispensable guardian against potential water disasters. Installation was a breeze, thanks to its compact design and straightforward setup instructions.

家にいない時が多く安心用に買いました。 作動しない事を望んでいます。

Non è richiesto hub aqara per funzionare, io li utilizzo con zigbee2mqtt e vanno perfettamente. Ottima anche la qualità costruttiva
