Perfect for kitchens, basements, and laundry rooms, it offers peace of mind through real-time monitoring and historical leak data. ## Description Water Leak Sensor provides an effective solution to protect your property. Easy setup and no wiring required; which makes monitoring even easier. You can put it everywhere you want to monitor, like laundry rooms, bathrooms, kitchens, or wherever there is a potential for leaks. When a water leak occurs, the sensor will not only send a loud alarm, but also deliver an APP notification to your phone. So you can deal with it in time to avoid water damage. Review: While these products are a bit more finnicky than others I've tried (mainly the Aeotec/Smartthings leak sensor).. the inclusion of the 'non-smart' audio alarm is AMAZING, and key for this kind of device (the alarm can be disabled in home assistant by the way). Pros: - Uses AAA batteries (included) - Pairs SUPER easy - Sensitivity is configurable via included metal 'tongs' - Alarm is loud enough to be easily heard, but not deafening (dogs really don't like the sound though) - Extremely compatible with home assistant via Zigbee Cons: - More finnicky vs the aeotec/smart things leak sensor - ONLY entity is leak/no leak, no other sensors included (i.e. temperature) - AS mentioned by others, size is a bit wonky, but its well worth it for the use of cheap AAA batteries and long battery life, and since these types of devices are hidden away anyway, its not likely to be an issue. Overall this device is great for the price and a great peace of mind addition to the smart home. Review: I purchased these to help monitor locations around the home that could have water leaks, including where the main water line comes into the house, my mechanical room, underneath various sinks and in our laundry room. They work perfectly with my Home Assistant setup. The devices were instantly recognized by my Sonoff Zigbee 3.0 USB Dongle Plus (connected to my Pi5 running Home Assistant) and I could setup everything from there. So far, zero complaints as they work like a charm. The ability to adjust the sensitivity by either adding or removing the arms is a wonderful bonus. For those folks frustrated that the siren/alarm cannot be disabled, I simply opened the devices and carefully de-soldered the leads that went to the alarm. I know this voids my warranty, but I wanted to use these wonderfully reliable and widely compatible sensors, just without a siren/alarm, so that's a risk I was willing to take. Removal was easy and after the leads were insulated, snap it back together and no more siren/alarm. And, if I do end up wanting the alarm back, all I have to resolder the wires and I'm good to go. Thanks for another great product, ThirdReality! ## Features - HASSLE-FREE SET UP AND FIT ANYWHERE: Setup is super easy, just place it wherever you want. With a compact design and optional small size, you are able to place Water Leak sensor on the floor of your kitchen, basement, laundry room, or any other flat surface where you would like to monitor for leaks.

The pictures show the holes facing up .. which seems to make it hard for water to get kn and trip.** A: The holes definitely remain facing up as water is not intended to penetrate the unit. You will notice the small screws on the bottom of the sensor, when water touches those screws it makes a connection that triggers the sensor. **Q: Can i change the push alert? It sends endless notifications over and over until its physically turned off. Maybe one every 5 min would be better.** A: No such feature directly with the unit, but you should be able to with your automation platform. **Q: do these work with google home / Assistant ?** A: Not sure, but they do work with Hubitat, using the generic Zigbee moisture sensor driver. If Google / Home Assistant has similar drivers, it would probably work. Perhaps the answer is in the reviews... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on 17 February 2026* While these products are a bit more finnicky than others I've tried (mainly the Aeotec/Smartthings leak sensor).. the inclusion of the 'non-smart' audio alarm is AMAZING, and key for this kind of device (the alarm can be disabled in home assistant by the way).
