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: Fiddly But Reliable - "But TST," I hear you cry (you really should shut off your microphone when you're not using it,) "How are you giving this wonder-device only four stars when it saved you thousands of dollars in repairs *the literal week you bought it?" That is an excellent question, Grasshopper. Attend: Because putting it together is *irritating.* You mount the little metal feeler-doohickeys after you take it apart to insert the batteries, and they do NOT want to stay where they're bid. Once you get it together, it stays. But some people proabably won't be able to manage it and will not use it because of frustration. I, however, perservered, and as a reward, the thing DID in fact alert me to a water leak soon after it started, and I was able to address the issue before any damage was done. And my Home Assistant instances gets along with it great. If you have a little mechanical patience, I recommend it highly. Otherwise get the Sonoff ones. ## 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 ### ⭐⭐⭐⭐⭐ Not perfect, but versitile *by M***E on February 17, 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).

Good build quality, and reliable operation so far. Stuff I've liked: It had the best range for pairing and operating of the ones that I've tried. It had a loud, on-board alarm. The version with the drip leak function can optionally detect very small amounts of water, depending upon physical configuration. It has paired easily and worked well with my Hubitat system. It uses common AAA batteries. Possible issues: Where an audible alarm is not wanted, another brand/model sensor would be needed. The case is much thicker than others in its class, and may not fit beneath a refrigerator or other device. The first unit I received used slot-head screws. A very small screwdriver was included in the box, a really thoughtful touch. But, a jeweler's kit, like many folks use to tighten eyeglass screws, would be much easier. The sensors in a subsequent order had screws that could be worked with either a Phillips or straight-bladed driver. Where a low-profile case, or a sensor with a remote head, is not needed, this is my choice so far for an inexpensive Zigbee unit. Background: Most homes have many potential sources of leaks - water heater, dish washer, clothes washer, refrigerator, bathroom plumbing, etc. - that could cause expensive damage. I decided to buy and try five different, inexpensive, Zigbee leak detectors that might work directly with my Hubitat home automation hub. They were by iAlarm, Neo, Thirdreality, and Treatlife, and a generic "Water Leak Detector Zigbee" was added to the mix. At the time of my purchase (August, 2023), each was slightly less than $20. All worked properly with my system using the Hubitat "Generic Zigbee Moisture Sensor" driver. All but the Thirdreality also worked with the custom "Tuya NEO Coolcam Zigbee Water Leak Sensor" driver, which adds an explicit state indication of online or offline. But, both drivers support current wet/dry status and battery % reporting. A tip would be to install the custom driver first, if desired, then let Hubitat choose it during device pairing. Also, each of these should be paired within a couple of feet of the hub, then moved to the desired location. Some thoughts about the group: Overall build quality of the group seemed quite good, with the exception of the generic "Water Leak Detector Zigbee", which was only mediocre. The Thirdreality and Treatlife devices have onboard alarms, and could be used as stand-alone detectors, although there appear to be several detectors available that are only stand-alone, and less expensive than the Zigbee devices. The Thirdreality alarm is much louder than the Treatlife's. The Thirdreality unit had a longer range than the others, both in pairing and in operation. It and the Treatlife both use common AAA batteries, but I haven't used these sensors long enough to be able to compare battery life. The Neo device was the only one with a "remote" sensor - limited to the length of the attaching cord, but still may be needed functionality. However, the cord actually plugs into the wall mount, not the unit itself, so the mount must be used when remote sensing. ## Frequently Bought Together - THIRDREALITY Zigbee Water Leak Sensor with Dripping Detection,120dB Alarm,App Notifications Enabled When Work with Home Assistant and Compatible Zigbee HUB Like SmartThings,Aeotec or Third Reality Hub - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings - THIRDREALITY Zigbee Temperature and Humidity Sensor Lite,Smart Thermometer and Hygrometer, Hub Required,Compatible with Echo Devices with Zigbee Hub Built-in,Home Assistant,SmartThings,Homey,Hubitat --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/381415431-zigbee-water-leak-sensor-with-dripping-detection-120db-alarm-app](https://www.desertcart.dk/products/381415431-zigbee-water-leak-sensor-with-dripping-detection-120db-alarm-app) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
