How exactly does this work / install? How does it detect a leak? Does it need to touch the water, does it have a photocell that "sees" water?

The unit has two metal pins on the bottom. When water gets under the device and touches the pins, it completes a circuit that activates the sensor. There is no photocell; it is contact-based.

Simply set in area that leaking water will accumulate. It has two contacts on the bottom that use the water as a conductor to complete the loop and send the alarm to your Nexia system.

You register the device like any other Z-Wave device...once the battery is installed, the process begins. Water needs to touch two button contacts to be detected, so it needs to be close to the potential leak, where water will settle.

It installs like a standard Z-Wave device, include it to your controller and set up a rule to alert you if it detects water. The water detection is accomplished with two metal probes, meaning it would need to touch the water.

It installs with your ZWave System. It has two sensors on the bottom that detects water. It takes two double A's. It really works well!!

You place it on the floor so that the two contacts on the bottom will detect moisture. Not sure if it works. Hopefully..... I have it on the floor next to my hot water heater.

I noticed that the area where the wire goes into the device is not sealed and depending on where or how the unit is installed I believe water can get in at that point. I purchased a simialr one again and placed silicone in that area. Other that that it is a good camera.

It has some type of a float that turns it on or off when the water fills up enough in the reservoir. You just leave it plugged in, run off or drip going into top of rez., and the clear tube on the the black nub there pictured leading to wherever you want it to pump out when float(or whatever) senses that it's full enough to turn it on. It will turn on and swoosh the water through the full long distance of the tube provided. You cut it to whatever length you want or just roll it up to your custom length. I've had it working for over a yr.-yr. and a half with out ever having to adjust or touch it at all for that matter.

The other answers are incorrect. This unit turns itself on and off every couple of minutes to sense the water. because of this they burn themselves out after 3-4 years I am now on my 3rd one after 6 years.

I'm pretty sure that this isn't designed for spotting the air itself, it is designed for testing the temperature of the surface area itself. So you would be able to spot where the wall is colder, but not where the actual leak is coming from. I think you are right, you need a thermal camera.

I have three of these in my vacation home to detect water leaks. It it meant for indoor use to be placed on a flat surface. It has two metal electrodes that when sitting in water completes a circuit. If you placed it outdoors It may or may not work but it would surely malfunction if left exposed for any length of time.

it has a water sensor however it gets fully submerged it may go bad. there are metal contacts exposed

Not sure why it isn't working other than you may have a bad unit. DO both units light up? If not, then it's bad. And I don't mean a good bad. I've had 3 of these so far since one got water in it but have had no other problems. Good luck!

This setup works via two probes. One high and one low. When both probes sense continuity to ground (though water) it fires the pump. Pump will run till both probes read no continuity to ground (sump crock empty). It is a good system and worry free.

the water stays on as long as something is in front of sensor, and if im cleaning the mirror i sometimes make faucet turn on from moving in front so they are easy to activate-these are installed at a church/daycare and have no issues the connections are like a typical faucet

Seems to be waterproof, although my light unit is under a roof overhang. If in doubt, you might Put a bead of silicone where water might invade. Works great, and is a good unit. Like the feature of not having a motion sensor to worry about and fail, as they all seem to do. So far, so good

Water source must be absolutely leak proof. . Check faucet and screw in connector. Must have washers. Also unit requires dedicated circuit. I had a lot of issues with electrical reset on power cord. I dealt with it. If I had it to do over. I would buy a gas model. You may want to consider a return.

I dont have a sprinkler system. When the solar cells get wet from rain they can get water logged and it seems to effect the connection to the light. Shaking the water out has so far always corrected the issue.

Not sure how you'd determine what detected heat was a water leak and not just heat conduction from the pipe.A good moisture sensor might work, or a pressure test of pipe sections.

I have had the leak frogs for 2 or more years. I haven't heard a peep from them till two weeks ago. It really works and I hadn't even changed the battery. Had a leak under the kitchen sink and it sounded off right away. Saved a lot of cash I expect. You can use them on any flat surface. It detects water by using the leaking water to close the circuit. Great peace of mind if you are home.

This is an indoor only sensor - it's not made for the elements, not water tight etc. in fact I wrapped the seams in electrical tape just to make sure water didn't get in the unit. My application is using one in my laundry and one in the room with my water heater and basement drain.

It has two contacts on the bottom to detect moisture. I just have mine on a floor near my water heater.
