GoveeWiFi Water Sensor 3 Packs, Smart Water Leak Detector, 100dB Adjustable Alarm Suit for Home and Basement, Leak Alert with Email & APP Push (Only Support 2.4G Wi-Fi)

I've never left a review for a product before, but feel compelled to do so for Govee. These detectors have now saved me from major water damage in my basement on 5 different occasions. This is an absolute must own for every homeowner; put them under every single water source in your home. Can't recommend these enough, it only takes one incident for these to pay for themselves 50 times over. Thank you Govee for making a great product.

I received the item and a box of five more sensors about an hour ago. I am professional at home construction, including the plumbing trade. Here's what I found.After setting up the first sensor to the internet, I proceeded to place that one under my kitchen sink. I looked under the sink with a flashlight and didn't notice anything on the bottom of the sink cabinet, so I slid the sensor to the back of the cabinet. On doing so, I felt a dampness on the palm of my hand as I placed the sensor. There was a film of water on the bottom of the cabinet. I waited to see if the sensor would go off, as it did when I tested it by wetting a finger and putting it across two of the terminals on the bottom of the sensor. Well, that film of water did not trip the sensor. Wondering why, I placed the sensor on a flat piece of plastic on my work bench and I could see there is a 1/16 inch or so of space between the sensor probes and the flat plastic sheet I put it on. That's the problem right there. A film of water on the bottom of a cabinet will not set the sensor off. The probes will not contact the water surface.Here's what I did. I removed the little rubber plugs from each of the four feet of the sensor. Use a sharp object. I placed the sensor on a piece of sand paper on a very flat surface. Rubbing down on the sand paper I sanded the plastic feet down to the same level of the metal probes under the sensor. Now the probes will touch the surface the sensor is resting on. I tried the sensor under the sink again and it immediately tripped the water alarm. A slow drip will not make a puddle of water in a cabinet. It will most likely coat the bottom of the cabinet as it's being absorbed into the wood or leaking out at the seems of the cabinet.Something about kitchen cabinets: The bottom of kitchen and bath cabinets is usually made of cheap particle board or some material equally water absorbent. A small drip will not form a puddle of water as you might think. The bottom of the cabinet will absorb a small water leak, like a very slow drip, for MONTHS. Probably until the bottom of the cabinet is ruined. You will be able to tell by the bottom of the cabinet sagging down. But here's what I do with my sink cabinets. I put a heavy bead of caulk around the edge of the inside of the cabinet where the bottom of the cabinet meets the sides. Then I apply two or three coats of varnish to the bottom of the cabinet (we're talking INSIDE the cabinet here). What this does is make the bottom of the cabinet somewhat water proof, enough that the cabinet material will not absorb a small leak. And a larger leak will run out the FRONT of the cabinet, rather than down the seams between the bottom and sides of the cabinet. And you will notice it before damage is done.Now, the Govee setup. I did find the setup a little confusing I'll admit. Especially when setting up to the internet. The app wanted me to connect my phone to the wifi of the gateway unit that comes with the sensor. I'm thinking, do I want to do that? And lose my home wifi on the phone? I ended up backing out of the setup. But going back into the app again, I found it was working. I pushed the buttons as directed and setup the 6 sensors I had without issue. As you do each one, and are looking for it in the app screen, pull down the screen to refresh it and you'll see the device you connected.I gave four stars because: The directions could be a little more precise with the wifi setup of the gateway. The sensor probes should be lowered to pick up any amount of water.Note: The first sensor I installed saved me a big headache had the dripping fitting decided to break sometime down the road. This one find paid for the sensors I put in today. An overall excellent product. Just sand down the feet.UPDATE: 6/29/21 - I had a sensor alarm in my bathroom vanity sink cabinet. I removed the stuff stored under the sink and didn’t see anything around the sensor. I moved the sensor and carefully felt the area with my fingers. With no visible water, the area felt slightly damp to the touch. I took a closer look at all the plumbing with a flashlight, and sure enough, one sink supply connection was the slightest bit wet. Maybe one drop per hour.My description above on how I modified the sensor probes to touch the surface (floor, etc.) had allowed the unit to alarm well before any water started to puddle and soak into the wood and ruin the cabinet.I highly recommend these water sensors and that you modify them as I suggested above.

We bought this sensor kit with some extra sensors two weeks ago to help monitor the house while we were on vacation. Setup was easy after an hour of unnecessarily confusion. Included batteries worked fine, it's a new installation so I cannot comment on battery life.The manufacture's directions are unclear ... THANK YOU to the Amazon reviewers who wrote terrific explanations to help the rest of us.How well does the Govee app protect privacy? This is not an accusation, it's just an unknown. So I didn't want it installed on the phone I use everyday. Here's an option that also makes it easy to connect to the required 2.4 GHz wifi:I installed the app on an old iPhone that's connected to our router's 2.4GHz "guest WiFi". Using the old phone, and after struggling with the unclear directions, the Gateway connected to guest WiFi and all six detectors paired to their gateway.I also assigned the detectors to location names (e.g. "Water Heater"), so any alerts would immediately direct me to the problem.Then I tested one detector; SUCCESS!!!The audible alarm sounded immediately. Then, within a minute this email arrived: "Your "H5054_48C5" has detected water leakage. Check the area soon to avoid water damage."Glad that the alert system works, I know there's a problem somewhere, but that cryptic serial number doesn't help to find it. Suggest that Govee add "location" to their alert messages.So I like this product. If Govee adds clarity to the installation directions and alert messages they would fully earn a five-star rating! ****
