THIRDREALITY Zigbee Water Leak Sensor with Dripping Detection 4 Pack, 120 dB Alarm, App Notifications Enabled When Compatible with Home Assistant and Compatible Zigbee HUB, Batteries Included

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.

The batteries last long in these...I haven't changed them yet and they have been going for months now. They have saved my bathroom cabinet at least twice so far. One with a very slow leak in the drain gasket that went bad. The other time was a loose p-trap. On both occasions the product worked as designed. I have it integrated with Hubitat and configuration was a breeze. I have a rule setup to notify me continuously on my cell via the Hubitat app until the fault is addressed. Very sensitive and solid connection across the entire home. I have one in the kitchen, the bathrooms, and even one in the attic in the water heater overflow pan. The alarm volume is loud enough and will get your attention when it goes off. Again great product. Love TR's products overall.

Great that it works as a dumb audible alarm without any smart-setup out of the box.Not happy with the cheap hardware that rusts, given that this is a product designed to get wet, you thought they would at least get galvanized or stainless hardware. After this got wet it no longer functioned until I took it apart and let it dry out completely, now it works again but it makes me wonder about longevity.

I use these with a Smarthings hub. The pairing has been easy and works everytime. There are no false alerts. They work flawlessly when I test them. Since they use AAA batteries, they are much easier to use than the old Smarthings sensors. My only wish is that they were just a little bit narrower. When I need to replace sensors, these are the ones I will use

Excellent water leak sensors for anyone using Smartthings! I have almost 10 of these throughout my home in every spot that could leak water and cause issues. The best part about these are that they emit a loud alarm if water is detected, so if you're away from your phone and at home than you'll know there is a problem immediately. I will continue to use this brand until I find something that has more features. I DO wish they had temperature sensors inside of them like others I used to use, but maybe they'll add them in the future. These have actually saved me twice so far, so well worth the money! Try and get them in sales, cause the regular price is a tad high in my opinion.

Plusses: Simple device makes noise and sends an alert to your home automation system when a leak is detected. Cute shape. Battery life looks good so far.Minuses: No regular reporting or consistent response to refresh requests makes it difficult to have confidence that the device is working without manually testing it. I'm using Hubitat; results are possibly different on other platforms. Tried to do a firmware update but the device or hub doesn't respond to that either.
