Review: Perfect for Home Assistant - Small and Reliable - 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.
Review: Splish, Splash, and No Crash - 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.

### ⭐⭐⭐⭐⭐ Splish, Splash, and No Crash

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.

### ⭐⭐⭐⭐⭐ Working with SmartThings Edge driver
*by S***N on March 24, 2023*

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.
