## Description

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 - desertcart.com

Review: Great peace of mind. - 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.
Review: My Overall Pick - 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.

## 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. Suggest to place your sensors near the washing machine, water heater, sinks, or dishwasher.
- INSTANT ALARMS: After Water Leak Sensor setup is successful, the Third Reality APP will push APP and free Email notifications to you and the sensor will sound an alarm when a water leak occurs. Water Leak Sensor can also be used when the internet is off. It features with a loud 120dB alarm, and loud enough to be heard even if leakage happens in basement or up stair within your home.
- APP FUNCTION:In the device detail page, Third Reality APP also displays the battery level, sensor’s real-time status and history view etc.
- 3-YEAR LONG BATTERY LIFE: Water Leak Sensor uses two AAA 1.5V Alkaline batteries for power, and the batteries are easy to replace.
- APARTMENT AND HOTEL MANAGER FRIENDLY: Connected to the Third Reality Hub/Smart Speaker, Water Leak Sensor can be monitored not only through the Third Reality APP, but also through the 3R-Protect Manager APP. You can go to the detail page of the “Water Leak Sensor Kit” to learn more about 3R-Protect Manager APP.
- More Smart Assistant Supported: Enabled by Smart Bridge MZ1 (Sold Separately), integrates with Apple HomeKit and Google Home, to achieve easy control and monitoring. Additionally, it supports software OTA (Over-The-Air) updates.

## Questions & Answers

**Q: How do you configured it with Smartthings? the Third Reality brand  in the hub does not give you any option to pair with a water leak sensor**
A: Please follow this video to configure the Water Leak Senor with SmartThings.

**Q: What is the correct orientation when placing this?  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...

### ⭐⭐⭐⭐ Works fine, but has few issues.
*by M***. on October 6, 2022*

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.
