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!
