Review: You need them! Buy them before the leak or you will after! - Yes, this is one of the devices that most people don't prioritize having or just start to discover their existence after a leak happened. Well, I've learned it the hard way after a pipe burst in attic and there was water damage all the way to the ground floor. And funny point is that in life we all pay sometimes a ridiculous amount of insurances, some compulsory, some by choice but often useless. These flood sensors are your kind of equivalent of insurance or better said prevention from consequences of a heavy flood, just long term and relatively cheap. And if we consider what major leaks can cost - then super cheap. Let me quickly summarize the key points so far: 1. Works and works fast. Either leaks or drips, once the liquid touches the sensor you will know instantly. Just make sure you are positioning it correctly and if possible in such places so you avoid false alarms. What do I mean? Well I've placed one of mines in the bathroom corner, close to the toilet. One of the evenings we all simply jumped up of the loudness of the alarm, which was due to my sons poor aiming in the toilet. I'm under impression that loudness and unexpected scream scared him so much that it made the aiming situation even worse haha. By the way don't worry, you can change the alarm volume and duration and this is exactly what I did after this case. 2. Decent app and good notifications. Well, this one is as important as the device itself, because if leaks happen when you're not home - you want to know about this fast and be able to act fast too. Actually, it's important when you're at home too. Beside reminders and emails - the phone pop-ups are very informative and useful. Just make sure you allow them! Setup was quick and straightforward, there is no rocket science behind it. I've tested it so far with Alexa and it works. I expect it to work with other claimed services from Google and Siri, but I'd personally won't rely on this as number one interaction or communications channel. I hope for my Alexa just to notify me when batteries are low - this will be super helpful, as obviously you want these sensor to be on and running and not dead if a leak happens. Connectivity throughout the house for me is also good, but make sure to test it if you live in castles or spread multiple sensors in separately standing granny flats, garages, etc. Don't just trust the claimed 120 meters as it will depend a lot on build materials, interference, etc. To summarise: This is a device that you hope that you will never need, but trust me you want it to be in your house just in case, for peace of your mind, because if a leak happens, you will thank yourself a lot. And if you knew about such sensors and did not buy one - it will be bitter! Anyway, hope my 5 cents help a bit. Stay well and dry haha! Cheers! Review: Good Quality - Excellent Price - Tested & all work according to instructions. Seem well made. A good choice if you don’t require WiFi capability. ## Features - Real-time notifications (no hub needed): After connecting to Wi-Fi, you can receive real-time notifications via email and remote app when drops, leaks or floods are detected, without the need to purchase an additional hub. Share devices with the family and they can also check the status of the house at any time (2.4GHz Wi-Fi and BLE) - High sensitivity drip alarms: This device is equipped with four sensor sensors at the top and bottom, which can detect a low water level of only 0.5 mm. If the water pipes drip and your soil becomes submerged or wet, the alarm will sound. The water leak detector is compact and practical in size, suitable for placement in laundries, water heaters, dishwashers, sinks and other places. - Includes loud alarm sounds: To help you stay alert, we have added high-level alarms of 100 dB, which means that even if there is a leak in the basement or in more remote places, you will know in time. Once discovered, you can silence it manually without worrying about sound issues. - IP67 waterproof, up to 24 months battery life: the water leak detector is designed with a fully sealed waterproof shell and can handle work environments with high humidity without any issues. It comes with 2 AAA batteries and has a lifespan of up to 24 months. When the battery is almost empty, our app will also send you notifications to remind you to replace them in time - Part of SwitchBot ecosystem, voice control compatible: use with SwitchBot Plug Mini or Indoor Cam, remotely turn off electrical equipment or check the status of your home if there is a leak. It can also support third-party services such as Alexa / Google / Siri / IFTTT / SmartThings. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CTJPCZQ7 | | Audible Noise | 100 Decibels | | Battery Description | Alkaline | | Battery description | Alkaline | | Best Sellers Rank | #66,747 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #240 in Safety Sensors & Detectors | | Brand | SwitchBot | | Built-In Media | SwitchBot Water Leak Detector | | Color | White | | Colour | White | | Compatible Devices | Smartphone, Tablet, Google Assistant, Amazon Alexa, Apple Siri, IFTTT, SmartThings | | Compatible devices | Smartphone, Tablet, Google Assistant, Amazon Alexa, Apple Siri, IFTTT, SmartThings | | Control Method | App | | Customer Reviews | 4.4 out of 5 stars 515 Reviews | | Item Dimensions L x W x H | 5.9L x 2.5W x 5.9H centimeters | | Item Type Name | Water leakage detector | | Item Weight | 68 Grams | | Manufacturer | Wonderlabs | | Maximum Range | 1700 Feet | | Model Number | W4402000 | | Mounting Type | Tabletop Mount | | Number of Batteries | 1 A batteries required.
