Govee Water Leak Detectors 5 Pack, 100dB Adjustable Audio Alarm Sensor, Sensitive Leak and Drip Alert, for Kitchen Bathroom Basement (Cannot Connect to Wi-Fi Directly)

these wireless battery powered water sensors work really well. easy to test, easy to silence if they go off. The app alerts you when their battery power is getting low. So far I've been getting over a year out of them between battery changes, using Eneloop rechargeable batteries.

Like swblake noted, the instructions for pairing, in the instruction manual are not correct. To pair a water sensor with a hub, assuming that you have already plugged the hub into an electrical outlet and successfully connected to the hub via the Govee app (Android/iOS), long press the lower button on the hub, for about 3 seconds. That will put the hub into pairing mode. Then, bring the water sensor very close to the hub (a few inches away), and long press the water sensor's button for about 3 seconds. Give it another 5-10 seconds for it to finish pairing. From the lights, it's pretty obvious when it's paired successfully. Once it's been paired successfully, you can then relocate the water sensor to your desired location.Interestingly, one of the water sensors actually detected an occasional, minor drip, that was occurring in one of my bathrooms, that I had not previously noticed at all.As a test of the battery levels, I replaced the batteries on one unit with older batteries, having a voltage of 1.17 volts each. I was pleased to note that when I refreshed the Govee hub app, it picked up that the battery level on that water sensor had gone down, from 5 bars to 2 bars.CAVEAT:I did another test where I removed the batteries entirely. Unfortunately, when I did this, and then refreshed the hub app's device list, the water sensor, from which I had removed the batteries, still showed up in the list, with NOTHING to indicate that there was anything wrong with the water sensor. In fact, as an additional test, I left out the batteries for 30 minutes, and the Govee hub was UNABLE to detect that the water sensor was no longer operational..This is a problem because, if a water sensor suddenly dies, the user has NO WAY to tell that it's died. And so they're left in a situation where they think the water sensor is still working when it actually isn't. This could very well result in a catastrophic situation where the user ends up suffering thousands of dollars in water damage due to this software fault.A better way to handle this situation is, if the Govee hub cannot detect a device, upon device list refresh, simply flag/highlight the device and, ideally email the user, regarding the water sensor that is no longer sending messages to the hub. Optionally, allow the user to specify the timeout duration, beyond which they want to receive an alert. For example, if the Govee hub hasn't received a status update from a device within a 5 minute time period, have the Govee hub send an alert to the user regarding said device..Hopefully, Govee will push out an update to resolve this important issue.Getting notifications on my Android phone, when a water leak is detected is pretty awesome! I actually created a custom ringtone, of a dripping sound, to associate with water leak notifications. Which helps to determine that it's a HIGHLY IMPORTANT notification..Getting app notifications, for water leaks, is a killer feature, for water sensors. Love it.And the idea of transmitting on 433 MHz frequency, to the Govee hub, instead of having each sensor connected directly via WiFi, is probably an excellent design decision, in terms of conserving, prolonging battery life, as direct Wifi connections would probably have required much bigger capacity batteries, due to their relatively higher energy requirements.

Installation was quick and easy, seamlessly connecting to my 2.4GHz WiFi network and working flawlessly with the Govee Home app. I can easily monitor each sensor's status from my phone.The alarm is loud, and alerts appear instantly on my mobile, which is essential for preventing major water damage.I placed sensors in high-risk areas—one in the basement, three in the bathrooms, and one under the kitchen sink. Since installing them, they’ve already detected water leaks twice, allowing me to fix the issue before serious damage occurred.These sensors provide incredible peace of mind—a must-have for any home!

So far these seem to be holding up after a few years. However, it starts chirping when the battery is dying (and odds are it will happen while you are sleeping at 2am). The battery cover has tiny screws to remove to gain access to the batteries, which is a really poor design. Upon replacement of the batteries, I just taped the cover on and ditched the screws.

These moisture detectors work excellent! I placed them in my basement below the bath tub. When the tub leaked it alerted us and was loud enough to hear clearly on the main level. Money well spent!!

These are unobtrusive and work well. Got them on sale. The convenience, quality and price would make me buy more if I need them. Nice loud alarm.

so these products are always tricky to get paired and I can dedicate the setup with my WiFi for the recommended 2.4 which after it finally caught the hub the sensors were quick connect - but after initial set up of 6 I thought of another area so repeated steps in set up but it will not - emailed their useless customer service - 7 days later no reply but survey sent to me where I replied not satisfied as not contacted for assistance no email nothing. So great product just know you will not get help if need. No phone contact cause they probably are aware of maybe only 1 person minding the store if any. I will continue to blast their customer service as it angers me.** so I tried the add on again after a week or so and it magically worked like a charm as did initial set up - have no idea what was wrong on my failed attempt but yes great add on no hiccups at all.** but sadly I give minus 0 on the customer service as there was none. Great water sensors just don’t need help. How sad.

I live in a sub that was apparently built on a filled in swamp so when my sump motor went out I had to rent the giant carpet cleaner machine to keep my finished basement from becoming a black mold sanctuary. The second time I had a sump issue was when the calcium deposits clogged the sump float mechanism and even though new, the sump did not engage until water reached my carpet.... I decided I needed a warning system. This box of gems recently saved my butt from a 3rd basement fiasco. They work. They are loud. They are worth every penny. They only work if you are home to hear the alarm.
