If you have Home Assistant for home automation and need some leak sensors these work great (as of the 2025.01 release of Home Assistant). But you need to understand how they work1) They only work over bluetooth. This is good, keeps the battery life long2) You need some whole house bluetooth receivers. If you happen to have shelly devices with the bluetooth capability (Like the plus series) then you're all set. Because Home Assistant can configure the shelly switches to listen and pickup bluetooth signals from all over the house.If you have these things, then setup is easy. Pop the included AAA batteries in, check Home Assistant and it will say it detected a Switchbot Leak Detector. Click "Yes, set it up" and you're done (but give it a better name). Shows up with the proper icon (water drop) and type (moisture).Now the real fun is the automation. I have a zwave whole house water shutoff device. It will turn the quarter turn valve on my incoming water line to my house. I grouped all my leak detectors and created an automation that says "If the group (IE any one of the group) detects water then shut off the whole house water valve". Tested it out and within 1-2 seconds of a water drop the valve is turning off. It also sends me a notification too.The sensors themselves are very sensitive. The top is dished a little so if a single drop of water hits the top it will likely set it off. The bottom contacts are pretty sensitive too but would take a very small puddle just due to how the sensor is on the bottom and water spreads.They do have an alarm too, it's not super loud, but it will get your attention if you're in the same room. Mostly though I bought them for the Home Assistant integration. There are cheaper sensors if you just want an alarm when water hits them.Water damage is the worst thing for a house, and also the most likely. Toilets, sinks, washing machine, water heater, anything with water should have a sensor next to it and ideally some automation to cut the water. In 20 years of home ownership I've only had 2 major issues and both were water related (water heater once, washing machine second). I'm all prepared to never have another one (fingers crossed!) I have 12 of these spread out around my house.

set up very easily and worked immediately. nicely done. I had trouble opening the battery compartment and used the support link. The chat is superior - bot referred me to an agent who picked up immediately.

I got this water sensor in 4 pack with much greater price than the old ones i have, and they are all the same in terms of functuons. This sensor uses AAA batteries which can be easily replaced. It took me less than 10 mins to set up all of them and now i am rest assured. Easy to use with the apps.
