yes that was me
You can get them here
This should also work

For the TR sensors with "drip detection," You could "extend" the sensing to another location by using something like doorbell wire and screwing the wires onto the screws (instead of the included optional probes. The ends of the wire would need to then be placed wherever you wanted to detect water, with the ends stripped back and placed at the desired distance apart from each other.
Conceivably, you could also strip the wire for a given distance and secure the stripped lengths next to each other on an adhesive strip or other medium. Then at any point along the length of that stripped wire, if water bridges that gap, it would trigger the alarm.
These sensors also have a "tip" screw and two side screws. The long part of the probe can be attached to either side screw, so both of these side screws have "sensing" capability in combination with the tip screw. So you could attached two sets of wires (one leg of each to the tip screw, and then the other leg of each to each side screw) and monitor two "remote" locations with this one sensor. Actually, now that I think about it, I don't see any reason why you couldn't attach multiple sets of probe wires to the screws, but not sure how many and how long the wire could be before the resistance messes with the sensor's sensing capabilities.
I might give this a try later today if I have time.
Thank you!!! 
Thank you! That's working great

I haven't used them yet, but I have a client who's asking me about the Zooz ZSE42.
The use case is a small (3-5 floors) of an apartment building, with approximately 4 sensors per unit, and 12 units in the building.
I'm not sure, but if I get a C8, and if I can pair these devices as LR, then I should be able to handle ALL of these sensors with one Hub in the super's office.
This LR stuff can be a real breakthrough technology.
It seems to me that depending on where the hub is located, you still may have issues through all of the walls in an apartment building if you’re using LR. You could give it a try to your farthest location, and if that doesn’t work, you could try putting a couple repeaters throughout the building and using a regular mesh network. The LR really comes in handy the most when you have a long distance to traverse with NO ability to put any repeaters in between (i.e., few walls), such as across a long outdoor area.

Have you tried this? We want to do a gate automation and considering Z-Wave LR for this. Our gate is about 600 ft away from the main house where the hub is.
I have not to that distance. Not sure what your setup is like, but something like the Zooz Universal Relay may be what you need for control, and touts up to 1,300 ft with LR, so 600 mostly outdoors seems doable.
Getting a little off on this original topic of this post, but if you post a new topic with this question, you might find somebody who has tried it already. Been seeing a lot of chatter about LR since it was added to Hubitat.

In a drawer or in the garbage? I would have paid shipping to take those off your hands 
I have two that I think are the original design, updated firmware, working fine for me.
The Third Reality water leak sensors report every hour using the "Third Reality water sensor" tmaster community driver. They do not report battery but device activity check will report when they fail to check in.

FWIW, I received a Third Reality water leak sensor today, and immediately modded it!
I removed the 3 screws, opened the unit, took the cover out to the garage and drilled a 1/8" hole at the bottom of the tear lobe (fat part) basically right atone end of the battery cage.
Removing the PCB with the attached battery cage was relatively simple, and i then found two screws to remove, that allowed, with some care for me to remove the battery tray entirely.
I then took one of these: tegongse LR6 AAA Battery Eliminator 2M USB Power Supply Cable Replace 1-4 AAA Batteries - 1.5v/3v/4.5v/6v Amazon.com: tegongse LR6 AAA Battery Eliminator 2M USB Power Supply Cable Replace 1-4 AAA Batteries - 1.5v/3v/4.5v/6v : Health & Household
I clipped the fake battery off, stripped a bit of insulation off the red and black wires, and soldered them to the + & - contacts on the pcb.
Then, because I'm an idiot, I unsoldered them, fed the wire through thw 1/8" hole, re-soldered the connections, put everything back together (sans the extra parts I removed) , plugged it into a USB wall socket, joined it. Chaged to the tmaster Third Reality Water Sensor driver, and we're off!
I have a Zooz powerstrip near my main Sump Pump with USB power, and I plugged this bad boy in, added it to HSM, and we should be good to go indefinitely!
A quick test indicated it both beeped and triggered an HSM notification.
With the 3VDC battery eliminator I used, the Water Sensor thinks the voltage is 3.1 Volts. -- with this, the Third Reality water sensor thinks its battery is 91% but, it should be fairly steady,
1 more battery sensor removed!!!!
S.
Update: I'm now using a voltage selectable model of adapter: here this model allows me to set the voltage to be ~3.4 VDC, which results in a 100% battery state.

I have about 10 of these. Been rock solid for years now with different hubs. Batteries last a long time. Just got one of the new one...batteries should even last longer. Great for either placing on a surface or using the cord to dangle down in something like a sump pump pit.
I have a couple of the Third Reality sensors and occasionally one or the other starts blinking red and becomes disconnected from the hub. I have to remove and reinstall the battery for it to reconnect and stop the blinking. Using the tmaster driver and it always shows present even when disconnected.
I have 2 of the ThirdReality Zigbee Water Leak Sensors. I don't think it has the dripping detection, if that is a newish feature as I got mine a year or 2 ago. I live in a condo and my A/C is mounted on a shelf about waist high in a closet with the space below it for the air inlet. I put one on the A/C shelf and one in the air handler. They have gone off a couple of times. Once when the pan overflowed the upper one went off, which was a real life saver. I had water come up under my floorboards many years ago when this happened and I didn't have such a warning. Just totally coincidentally the lower one went off about midnight last night, but I was still up. Turned out there was just a bit of condensation, but it shows how sensitive it can be.
One, BTW, I did a rule to get a notification. I got one for the 1st alarm months ago, but not last night. I also read a thread today that this lack of notifications (at least on an iPhone) is a known issue and they are working on it. When they have it working it tells me which one went off and when. I also wrote as part of the rule to repeat this every 2 minutes until I cancel it. It probably wasn't needed, but once one is wet then I get a notification if it is dry for 2 minutes.
So all-in-all I'm very happy with them.
