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

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.

"But TST," I hear you cry (you really should shut off your microphone when you're not using it,) "How are you giving this wonder-device only four stars when it saved you thousands of dollars in repairs *the literal week you bought it?" That is an excellent question, Grasshopper. Attend: Because putting it together is *irritating.* You mount the little metal feeler-doohickeys after you take it apart to insert the batteries, and they do NOT want to stay where they're bid. Once you get it together, it stays. But some people proabably won't be able to manage it and will not use it because of frustration. I, however, perservered, and as a reward, the thing DID in fact alert me to a water leak soon after it started, and I was able to address the issue before any damage was done. And my Home Assistant instances gets along with it great. If you have a little mechanical patience, I recommend it highly. Otherwise get the Sonoff ones.

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.

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.

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.

Piccolo stupido apparecchio che mi ha già avvertito per due perdite di acqua nel sottolavello, evitandomi grosse spese di ripristino dei mobili. Lo consiglio proprio

A good value for money and very easy to use leak detection device. Simply add batteries (supplied) connect the extension arm if desired and it's up and ready to go. Noise level is adequate ( not officially measured it's decibel level) but I've been able to hear it from another room. Pleased with my purchase.

Ich habe bereits unterschiedliche Zigbee-Wassersensoren unterschiedlicher Hersteller sowie Sensoren von Homematic IP im Einsatz. Ich habe diesen Sensor gekauft, um ihn im Keller hinter der Waschmaschine zu platzieren - um im Falle eines Defekts an Waschmaschine oder Zu- oder Ableitung informiert zu werden. Auspacken und erster Eindruck: Die Form des Sensors (als überdimensionaler Wassertropen) mutet erst einmal seltsam an - ist aber letztlich ja auch nicht relevant, wenn dieser irgendwie hinter oder unter einem zu überwachenden Gerät platziert wird. Ansonsten macht der Sensor einen stabilen und wertigen Eindruck, die Metallschienen (für die Tropferkennung) mussten noch montiert werden. Integration und Funktionalität: Das Anlernen in HomeAssistant hat problemlos funktioniert, das (schon vorhandene) Programm für die Benachrichtigung war schnell um den neuen Sensor erweitert. Ich habe den Sensor mit unterschiedlichen Mengen Wasser getestet, das Melden hat immer zuverlässig funktioniert. Der Alarm ist deutlich zu hören, aber nicht zu vergleichen mit einem Rauchmelder. Fazit: Es gibt noch etwas günstigere und kleinere Sensoren - aber die preislichen Unterschiede sind gering und die Größe spielt im Alltag bei solchen Sensoren ja selten eine Rolle. Bzgl. der Funktionalität gibt es nichts zu banstanden. Ebenfalls positiv zu erwähnen ist, dass der Sensor mit AAA-Batterien funktioniert - bzw. dann auch mit entsprechenden Akkus. Das spart das Nachkaufen (teurer) Knopfzellen.

Good thing to know: - Works flawlessly with Smartthing IF you do "Add device" then "Scan nearby". - Dripping Detection : it means that if there is water on the ground, it will be picked up earlier than without. Basically, it is just an extra band of metal increasing the area where the water is detected. (you have to install them by yourself, a screwdriver is provided). Without the dripping detection option, 2 screws on the back need to get wet in order for an alarm to be raised. - 120dB Alarm. Seems loud, but in the end not so much.

Works as expected and the battery last long time. Used with Home Assistant and paired with Z2M.
