Aqara Water Leak Sensor 3 Pack, Zigbee Wireless Water Leak Detector for Alarm System and Smart Home Automation, Requires AQARA HUB, App Notifications, for Kitchen, Bathroom, Basement, Works with IFTTT

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’m really impressed with this Aqara Water Leak Sensor 3 Pack. Setup was quick and seamless using the Aqara Hub, and the Zigbee connection has been rock-solid ever since. The sensors are compact and easy to place—perfect for under sinks, near appliances, or in the basement. I tested them with a small amount of water, and they instantly triggered an alert through the app. Notifications come in fast, which gives great peace of mind. I also love that it works with IFTTT, so you can integrate it into your broader smart home setup. This is a great investment for anyone looking to prevent water damage and stay ahead of potential leaks. Highly recommend!

The Aqara Water Leak Sensor is a compact and responsive device that shows great promise. Its small size and quick setup make it easy to place strategically around your home. The sensor's impressive speed in detecting water leaks is a standout feature, offering peace of mind against potential water damage. However, there are some critical limitations to consider. First and foremost, the sensor requires an Aqara hub, which excludes it from compatibility with other Zigbee hubs, even though Aqara produces some of the best in the market. This limitation is a significant drawback for power users who prefer more flexibility in their smart home ecosystem. Additionally, while the sensor indicates a leak in the Aqara app, setting up a notification for a leak requires additional steps. The app doesn't clearly guide users through this process, which could lead to missed alerts if not configured correctly. The sensor is advertised to have a 2-year battery life, though I haven't owned it long enough to confirm this. Replacing the battery is straightforward as it uses a common coin cell battery. Despite these shortcomings, the Water Leak Sensor's core functionality is impressive. Its rapid detection time and reliable performance make it a valuable tool for protecting your home from water damage. However, potential buyers should be aware of the limitations and be prepared to invest in an Aqara hub and spend time setting up notifications.

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.

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.

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.

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.

Greate small sensor that you can put under the sink, washer or dishwasher in case there is a leak. I love those, small and work great.
