Review: Will buy more - Easy to install and love the fact that it does not need a hub, worked very well-detect water leak and send notifications through wifi. Exactly what I needed.
Review: Works great with Home Assistant and Shelly bluetooth switches - 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 work 1) They only work over bluetooth. This is good, keeps the battery life long 2) 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.

### ⭐⭐⭐⭐ Good, but here is how it could be better
*by N***Y on August 27, 2025*

These little things work very well...they go off with even the slightest bit of water . the alarm is a decent level of loud depending on the size of your home and where its located. I have them near toilets and near my water heater, laundry. Under sinks. where there are high pressure water lines. I wish they could link to a wifi/or direct device to device connection to an emergency shut off valve. thats my only issue with it...(unless im missing something) but letting you know you have a leak is cool, shutting the water off at the main is Great!! becuz after it tells you there is a leak...if you are not home, OMG, u will freak out and then have to get home...so having it be able to link to a emergency auto shut off valve would complete the circle . they should make one , then this system would be Amazing
