Bought 15 & all were included successfully into Home Assistant and working fine after a few days. I like that these leak sensors touch the floor since I want to find leaks ASAP. Yes, the sensor might get damaged by water over about 1/8" deep, but I'll get notified way before the water gets that high. I'm fine with losing a $30 sensor to save hundreds or thousands. Some sensors I looked at won't sense water until the water is 1/8" or more. Too late in many cases. They have a very small footprint & easily hide behind toilets & under sinks. They seem to wakeup every 6-12 hours to update the battery status back to controller. So far, so good. If I have issues, I'll update this info.

I have 3 of these in my seasonal house in Florida sensing plumbing leaks around the kitchen sink, water heater and laundry. They linked right up to to my Z-Wave hub and Home Assistant HA software, and I'll know instantly if I have a leak.

The design of this leak sensor boggles my mind - and not in a good way. They are very low profile, which means that the electronics are almost certain to get wet with even a small amount of water. The case does not even seem to be water resistant. Really?They also go through batteries fast if they detect water. I have gone through 2 batteries in less than a month on a sensor that detected water. It seems like as soon as it detected water it starts eating the battery.

It worked fine initially (with Indigodomo) but then stopped responding after roughly a year. New batteries didn't fix it. Not good, when water egress can mean disaster.

These things are great. Super small and compact, and they react instantly and have never failed to alert me...But they have failed.If you don't get to the leak within a short period of time and they sit in water for too long, they are dead (or messed up).I guess the housing isn't water proof, which you'd think would be a pretty important feature on something like this.I have 10 of them around the house and they are a lifesaver, but I have had 3 of them die now after confirming a leak.If it happens in the middle of the night or while you're away, and you don't get to it to try it off, it will either completely stop working, or just go wonky and start triggering randomly and will need to be replaced.If they were waterproof, I'd say they were "cheap" and a heck of a deal.But they're "expensive" if they're a disposable item.Might have to switch back to the ones with an external probe for my next replacement (I'm shopping for one right now because I just went through this today).

The ZSE42 added easily to my ISY994 setup. It's a remarkably tiny thing, but my tests on a damp paper towel shows that it reacts very quickly to dampness and also signals dryness quickly. Like all these self-contained sensors, the ZSE42 is not designed to be flooded or immersed in water. I will be using it to trigger a whole-house water shutoff.The coin cell battery is said to last about a year. It reports its battery level and can send a signal when the level falls below a certain point, though I haven't yet figured out how to detect that. There is also a periodic "heartbeat" signal to indicate that it's still active.

Our dishwasher leaked & caused damage to our floor & the ceiling in the unit below us, so adding a water sensor was an obvious necessity. The Zooz device was FAST & Simple to include to my SmartThings system. Testing was incredibly fast - I just placed the device on a wet paper towel and received an instantaneous notification on my phone (so did my son at his office!). Picking the unit up sent an instant notification that the sensor was dry. I'll be getting a few more of these!
