THIRDREALITYZigbee 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

As a Home Assistant user, finding reliable devices to protect my home is a top priority. I can confirm that these THIRDREALITY water leak sensors integrate perfectly into a Zigbee network and are an excellent choice for anyone looking to monitor for potential leaks.#Integration and SetupPairing these sensors with my Home Assistant setup using a standard Zigbee coordinator and ZHA was effortless. I simply put the device into pairing mode, and Home Assistant discovered it immediately. The binary sensor for water detection was instantly available to use in automations, requiring no special configuration. I had all four sensors from the pack set up and placed in under 15 minutes.#Performance and FeaturesThe standout feature is the built-in 120 dB alarm. While getting a notification on my phone is great, the peace of mind that comes from knowing an incredibly loud siren will go off at the source of the leak, even if my internet or server is down, is invaluable. This redundancy makes it a truly reliable safety device.I've placed them in all the usual high-risk spots: under the kitchen sink, behind the toilets, and next to the washing machine and water heater. I tested one with a bit of water, and it triggered both the piercing local alarm and the Home Assistant notification almost instantly.Pros:* Pairs flawlessly and easily with Home Assistant.* The 120 dB local alarm is a fantastic feature for offline reliability.* Fast and sensitive detection for both pooling water and drips.* The 4-pack offers great value for covering multiple areas.* Good battery life, and the required batteries are included.Cons:* As with any Zigbee device, a compatible hub is required.* The alarm is genuinely loud, so be prepared when you're testing it!For any homeowner, especially those already running Home Assistant, this 4-pack is a smart and affordable investment for protecting your property. I highly recommend them.

These leak detectors are great. I grab them when they go on sale because you once were able to get them for $14. I use SmartThings to add them to my Ecosystem and Home Assistant to handle the automations. I put them in all my bathrooms, in the laundry room, under the kitchen sink, near the basement sump pump. What's great is they have an audible sounder making it easier to locate which one is tripped, even though my automations text me the location. The newest version now has some included hardware to increase the sensitivity of the sensor. It consists of 2 metal arms that attached to the screws to make the detection area smaller. SmartThings was able to add these without incident. After putting in the batteries a blue blinking light on the sensor will indicate its ready to pair, open SmartThings, add a new device and scan for nearby. That's it. I've been using these for a couple years now. Battery life is good and reported in SmartThings so you can create a SmartThings automation to let you know when the battery is low. Overall, this is a really good sensor for the price.

These work and are easy to set up. Water is detected by two of the bottom screws contacting water.As shipped the screws are inset about a millimeter. And the screws are not close together.To make it detect in a smaller area, you can screw on two parts which form a smaller gap so you can detect closer together therefor a smaller puddle.However once you do this, the screws are now bot recessed and touch the floor. In my case this makes to alarm go off even if the floor is just damp from humidity or steam.I may have to put tape ever them or think of something else. It’s a small flaw but something to consider.

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.
