Review on 🌊 Govee WiFi Water Sensor: 100dB Adjustable Audio Alarm & Smart App Alerts, Leak & Drip Detector for Home, Basement | Email Notifications (Not Support 5G WiFi) by Roger Alexander

I received the product and a box of five other sensors about an hour ago. I am a professional in home construction including plumbing. Here's what I found. After connecting the first sensor to the internet, I placed it under the kitchen sink. I looked under the sink with a flashlight and didn't see anything on the vanity floor under the sink, so I moved the sensor to the back of the vanity. At the same time, I felt moisture in my palm as I installed the sensor. There was a film of water on the bottom of the cupboard. I waited to see if the sensor would work like I did when I tested it by wetting my finger and applying it to the two connectors on the bottom of the sensor. Well, that film of water didn't work on the sensor. Wondering why, I placed the sensor on a flat piece of plastic on my workbench and saw that there was a gap of about 1/16 inch between the sensor probes and the flat sheet of plastic I was laying it on. That's the problem. A film of water on the cabinet floor does not trigger the sensor. The probes do not touch the water surface. Here's what I did. I removed the small rubber plugs from each of the four legs of the sensor. Use a sharp object. I placed the sensor on a piece of sandpaper on a very flat surface. While rubbing with sandpaper, I sanded the plastic feet down to the level of the metal probes under the sensor. The probes are now touching the surface on which the sensor is located. I tried the sensor under the sink again and the water alarm went off immediately. Slow dripping will not create a puddle in the closet. It will most likely coat the bottom of the cabinet if it penetrates the wood or gets onto the top of the cabinet. Something about kitchen cabinets: The bottoms of kitchen and bathroom cabinets are usually made of cheap chipboard or other material. water absorbing. A small drop doesn't turn into a puddle of water like you might think. The bottom of the cabinet absorbs a small amount of leaking water, like a very slow drip, for MONTHS. Probably until the bottom of the closet gets damaged. You can see the bottom of the closet sagging. But here's what I do with my vanity cabinets. I applied a thick coat of caulk around the edge of the inside of the cabinet where the floor meets the sides. Then I apply two or three coats of varnish to the bottom of the closet (here we are talking INSIDE the closet). This makes the bottom of the case somewhat waterproof, just enough for the case material not to absorb a small leak. And the bigger leak is coming from the FRONT of the case, not through the seams between the bottom and the sides of the case. And you'll find out before the damage is done. Set up Govee now. I found the setup a bit confusing, I'll admit. Especially when setting up the internet. The app wanted me to connect my phone to the wifi gateway that comes with the sensor. I think do I want this? And are you losing your home WiFi on your phone? In the end I gave up the installation. But when I got back to the application, I found that it worked. I pressed the buttons as directed and set up the 6 sensors I had with no problems. If you do this and look for it on the app screen, swipe the screen down to refresh and you will see the connected device. I gave four stars because: Directions could be a bit more accurate with Wi-Fi gateway setting. The probe probes must be lowered to collect any amount of water. Note. The first sensor I installed saved me a lot of headaches if a leaking faucet broke at some point along the way. This find paid for the sensors I installed today. Overall a great product. Just grind the legs. UPDATE: 6/29/21 - I had a touch alarm in my sink cabinet. I removed the stuff stored under the sink and saw nothing around the sensor. I moved the sensor and gently scanned the area with my fingers. With no visible water, the area felt slightly damp. I carefully inspected all the plumbing with a flashlight and sure enough there was a little damp in a connection to the sink. Maybe a drop an hour. My above description of how I modified the sensors to touch the surface (floor, etc.) allowed the unit to sound an alarm long before water began to build up and seep into the wood and destroy the cabinet. Highly recommend these water sensors and change them as suggested above.
