Review: The Best SmartThings Sensor Replacement—With One Huge Upgrade! - I purchased the THIRDREALITY Zigbee Water Leak Sensor as I needed to buy additional water leak sensor for my existing Samsung SmartThings platform. Samsung no longer makes water leak sensors, so I needed something that would integrate into my existing platform. Overall, it’s a good sensor that gets the job done, but there are a few design details worth noting if you’re coming from older Samsung smart sensors. The Good: Flawless SmartThings Integration: Pairing with my Samsung SmartThings hub was quick and painless via Zigbee. It was recognized right away, making it super easy to set up automation routines (like sending push notifications or triggering smart shutoff valves). Super Loud Local Alarm: The built-in 120dB alarm is bright and loud! Even if your phone is on silent or you lose internet connection, you will hear this thing going off in the house if there’s a leak. That's a huge plus and something that was not available in the Samsung SmartThings sensor. If you go to sleep and put your phone on silent you will not hear a phone notification, this is when the audible alarm from the sensor comes in handy big time ! App Notifications: Getting instant alerts on my phone when water is detected adds a huge layer of security when away from home. It runs on 2 AAA batteries, so no more buying of those CR123 batteries that I only used with my SmartThings water leak sensor! The Room for Improvement: Contact Probe Design: My main gripe is with the design of the sensing contacts on the bottom. I really prefer the old-school Samsung SmartThings water sensors that had two simple, direct metal pins sticking out from the bottom to detect water on the floor. This THIRDREALITY unit uses a slightly different/weird contact design that doesn't feel quite as straightforward for detecting paper-thin pools of water as the original SmartThings probe design did. Final Verdict: Despite my preference for the classic SmartThings probe design, this sensor performs reliably, pairs seamlessly via Zigbee, and the combination of an app notification, the fact that it uses standard AAA batteries and it has a 120dB local siren makes it a solid buy for anyone building out their smart home leak detection system from scratch or adding additional sensors to existing system like I did.
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.

### ⭐⭐⭐⭐ THIRDREALITY Zigbee Water Sensor
*by D***K on May 4, 2022*

Easily hooked up to the Habitat hub. The device size is small enough but not the smallest leak sensor. Only issues I see is that the sensor plates sit too high on the floor, about quarter inch. I purchased the extra sensitive plates with the leak sensor. They are metal and connect under the screws on they bottom of the device. The water is sensed from the front screw to either back screw. That distance is several inches apart and a quarter inch off the ground. Without the plates it would detect water when it was in a flood and the water level reached a quarter inch high. I feel that is a little late. Would rather know there is a leak at first sign of any water. The add on plates do better but they still sit about the thickness of a quarter from the floor. Better than without. I have other water leak sensors with two metal contacts about half inch apart and sit right on the floor. Much better to detect a leak before it gets out of hand. On this sensor, you could add two wires to the screws on the bottom and put them on the ground near each other for better sensitivity. The connections are sensitive enough to go off just touching with my dry fingers. Didn't need water. That's good news. I used this device for a a sump pump water alert. I purchased a small sump pump float switch that attached to the side of the sump pump PVC pipe. It had two wires which I hooked to the two sensor screws. When the small float goes up the alert goes out. This device works really well for that. I could have used a contact sensor in my case but this sensor was cheaper and it has the extra function to detect water. Although water at a depth high enough to trigger the alarm would be at the point the water level filled the room and started to rise. The sensor also has a sound alarm beep, like a smoke detector. And it sends a signal too to my phone, thru the Habitat hub. Devices uses two AAA batteries. Need to unscrew the small screws to put in batteries. Kind of a pain but hopefully do not need to do that often. Looks like the Hubitat provides the battery life in percent. I should know when the battery is getting low without taking the device apart. Overall, recommend with modification to extend the sensors. The access to the sensor wires, thru the screws, make it easy.
