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: Not perfect, but versitile - 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). 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.

## 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...

### ⭐⭐⭐⭐ 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.
