Customers have issues with the connectivity of the alarm. They mention that it always loses connection, is too weak to successfully connect to the zigbee network, and has initial issues with connection using ZHA. Some customers also report issues with losing communication with SmartThings and dropping off the network. They say the initial connection is all that works and even that took quite a few attempts. Some say they had problems pairing it with Hubitat and the latest ST app, even after installing a custom DTH.

"...The LQI shows a fairly weak connection, which is surprising given that it's only 10-15 feet away through two interior walls...." Read more

Reliable and saved me hundreds of dollars.
5 Stars
Reliable and saved me hundreds of dollars.
I have been running one of these in my basement for over a year and it immediately alerted me via Home Assistant when I had a basement floor drain backup. I was able to save a lot of items that would have otherwise got flooded with sewer water. The sensor itself floated and did not get ruined. It is at 58% battery life, so I expect it will maintain battery life for at least another few months. 1-2 years of life off a coin cell battery is perfectly acceptable. After my basement flood, I purchased 3 more to put in other areas that could experience water leaks. These are well worth the money to have an early warning of a pipe break, toilet leak, dishwasher leak, sewer backup, etc.

Water mishaps in a home can be like uninvited guests at a party - they show up unexpectedly and can be a real downer. That's where these nifty water sensors come into play. I picked up a pair, one for my heat pump water heater and the other for my washing machine. I must say, they're like the silent, watchful guardians of my appliances.

Imagine this: you're sitting down for your favorite TV show, and suddenly your phone pings with a notification that could rival any cliffhanger - water detected! That's what happened to me. Within seconds, I was able to avert a mini flood from my washing machine. The sensor's responsiveness and the immediate alert to my phone were impressively efficient. It was like having a personal home guard without the need for treats or belly rubs.

The setup? A breeze. Even for someone who often gets baffled by tech gadgets, I found the installation process to be straightforward. The design is compact and unobtrusive, blending in seamlessly with my home decor - a small but mighty presence.

The second sensor, stationed like a silent guardian angle next to my water heater, hasn't had its moment of glory yet, but I sleep better knowing it's there. It's like insurance; you hope you never need it, but you're grateful for its existence.

Sure, water sensors might not be the most thrilling topic at your next dinner party, but they're definitely a conversation starter. "Did I ever tell you about the time I nearly had an indoor pool?" is a great icebreaker.

Overall, these sensors have brought a sense of security and peace of mind to my home. They're the unsung heroes in the world of home appliances, quietly guarding against potential disasters. No capes needed, just a reliable alert system and a little bit of tech magic.

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 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.

5.0 out of 5 stars Basic WiFi Water Leak Sensor
Reviewed in Canada on December 4, 2023
These Aquara water leak sensors were easy to pair and add to the Aquara M2 Hub. Yup, you need an Aquara hub, so that's an extra expense, but the sensors are reasonably priced. We put five around the house. The Aquara app is easy to use and shows the sensor info like battery and signal strength. The sensors further away from my WIFI hub show a "weak" or "fair" signal. I hope this does not impair the sensor notifications.

5.0 out of 5 stars Vertrauensvoller Wassermelder!
Reviewed in Germany on April 23, 2024
Ich habe kürzlich den Aqara Wassermelder erworben, um mein Smart Home-System zu erweitern und vor möglichen Wasserschäden zu schützen. Dieser Wassersensor hat meine Erwartungen übertroffen, besonders im Vergleich zu anderen Produkten wie den Bosch Smart Home Wassermeldern, da er deutlich früher auf Feuchtigkeit und Leckagen reagiert.

Die Einrichtung des Aqara Wassermelders erfordert einen Aqara Hub, was zu beachten ist, wenn man das Gerät in Betrieb nehmen möchte. Die Installation ist einfach und der Melder selbst ist kompakt und unauffällig, was ihn ideal für verschiedene Bereiche wie Küche, Badezimmer oder Keller macht.

Die Leistungsfähigkeit des Aqara Wassermelders ist beeindruckend. Er reagiert sehr schnell auf die geringsten Anzeichen von Wasser, was mir ermöglicht, sofort zu handeln und potenzielle Schäden zu minimieren. Die Alarmfunktionen sind laut und deutlich, was zusätzliche Sicherheit bietet.

Insgesamt ist der Aqara Wassermelder ein zuverlässiges Gerät, das eine wesentliche Ergänzung für jedes Smart Home darstellt. Die frühe Erkennung und schnelle Reaktionsfähigkeit machen es zu einem wertvollen Werkzeug, um Wasserschäden effektiv vorzubeugen. Ich würde dieses Produkt jedem empfehlen, der nach einer zuverlässigen und effizienten Lösung zur Wasserdetektion sucht.
