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

I bought these in November of '25, and so far they're working great. They were easy to connect with my Hubitat Hub with no problems, and work great. I was able to easily set them up, to have Hubitat send notifications to my iPhone (I always have it with me), and one of my Echo's. The alarm on the sensors is a decent volume, but not sure i would hear the one in the basement if i was up on the second floor. I also like the fact that they use AAA batteries (I use rechargeable's) instead of button type batteries. The drip sensor attachments are really sensitive, I had to put a piece of not paper under the one in my basement, as the bare concrete floor would trigger false alarms. I haven't run into any problems with them disconnecting from my Hub as some people have had problems with, but will update this if i do.

The Thirdreality sensor case has a distinct form factor, but in a house with a number of other small sensors of various types, that could be a good thing. 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.

I ordered two of these. The sensor works well detecting leaks, but like others mentioned, it will need a large puddle to trigger it. This was very easy to fix by bending the metal drip detectors down a bit so they touch the floor. The audible alarm is high pitch and quite loud. The sensor connected easily to Home Assistant using ZHA and Conbee II. My only complaint is that both sensors report battery strength at 63%. I tried multiple fresh batteries, including Energizer lithium, but that didn’t make any difference.

I bought these to replace several unreliable Z-wave detectors I had in Home Assistant. These paired very easily, and work flawlessly. They already warned me of a spill and have accurately gone off when we mopped too close to one. They’re very loud and I can hear one several floors away. I’m pleased with them and while they’re a bit bulky they fit into the places I need. I currently have 8 deployed across the house and plan to add 8 more to cover all possible leak locations. I love that they accurately report battery life and use standard AA batteries that I can readily swap out and use rechargeable ones.

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!

These work great in Home Assistant (ZHA). run for 1.x years on AA batteries, and make an audible noise when water is detected The only two downsides are the shape, which is a little silly and the lack of a cable sensor which is OK for some applications. They also come with a drip sensor attachment. I mount mine on to a washcloth under a sink. The washcloth soaks up any leaking water and transmits it to the sensor. These mesh well with everything and will switch to a different router if the mesh changes. They mesh especially well with other third-reality gear.

Top super Funktion

messe pile, collegati all’hub sonoff (SONOFF Zigbee Hub, Hub Bridge... https://www.amazon.it/dp/B09ZQQZSQZ) in un baleno, aggiunte le due lamelle, testati e posizionati. Zero problemi, spero non mi avvisino mai…

Lässt sich zwar mit IOBroker koppeln, aber meldet nicht den Alarm weiter....piept nur...dann brauche ich auch kein ZigBee

È un articolo molto semplice da montare e che funziona senza bisogno di collegarlo a niente. Bisogna svitare le tre viti per aprire il guscio e mettere le pile. Se si utilizzano le linguette metalliche le viti sporgono leggermente sul fondo permettendo un contatto con il pavimento. In questo caso basta una minima quantità di acqua, anche solo uno strato sottile, che l'allarme inizia a suonare.
