Water Leak/Moisture Sensor - Rope Type

I am looking for a Hubitat compatible water leak/moisture sensor that has a "rope like" sensor. I have a wide area under an A/C unit that gets "moist" or wet but not standing water. I have SmartThings sensors but they usually require some water to accumulate before tripping. Also would love one with long battery life. Any help is appreciated.

You could try this type of leak sensor.

I have been hoping to find inexpensive sensor rope that I can attach to a sensor with screw terminals, like the one from Third Reality... But I haven't been able to find the right stuff yet. It's all either expensive, or it looks too stiff to lay easily on the floor.

Absolutely a 'wait till their sale' purchase....but...it's reliable and there is a point where you think "how costly are the consequences of a missed water leak". Which of course is what they are thinking when they price it like this.

That said, it's only a matter of time before someone undercuts their pricing with something just as reliable.

These seem to work and there is a 10' one for an extra $5.

Sinope’s not the only source for a water leak sensor cable. @calinatl linked to one, here’s a thread that mentions another one:

I bought some detection rope by the foot on AliExpress and installed my own connector on it to interface with the Calypso Water tank controller. I payed somewhere around 20$ for 5 meters + some 1/8" stereo plugs with a cable from Amazon that I just soldered the appropriate wires on the detection cable and used shrink tubes to secure the connections and tidy everything at the end so that it won't separate.

If you like it can you link it? I looked at that stuff, and while I cannot be sure from pictures, it all looked stiff... Like it would be hard to make it lay flat without fastening it down. That's why I didn't try it myself.

This is the one I bought (5m), but there are a few others out there. Yes it feels bit stiff but lays down flat no problem (except maybe the ends that tend to curl up a bit but lay flat after a while)

Thank you kindly for the review!

Looking at this product on Ali evokes a range of OFF TOPIC emotions ranging from:

  • damn them if they copied/stole the IP for this

  • damn the Canadian vendor for "scalp pricing" at 10x more, ESPECIALLY if the same damn factories in China are making it for them !

I would say probably more like 20x markup, the price we are paying is surely a lot higher than buying say 10,000 or more of them pre made to there specs, but also could have bought bulk detection cable and make them themselves since Sinope also caters to custom commercial solutions especially all the water damage prevention for apartment buildings and more. So if a client needs a detection cable that is 25 feet long, they can custom build them to there specs. I actually work 500 feet from them and they do have quite a few employees and I know it's not just warehouse and shipping because I've been in there a few times and only about 1/3 of the building was for that.

Idea update to thread on the theme of less expensive perimeter cable solutions-

One of these:

and

Two of these, or one and the original puck sensor:

...plugged together and presto you've got sensing in two different directions. We'll see if it causes any problems, so far it seems to work as you'd expect.

Be advised that all these "plug in capable" sensors have their max extension segments limits. Can't recall the Sinope spec but I'm pretty sure at least 3 segments lengths are allowed. Also note that some folks have experienced that these First Alert (Resideo) cloth covered cables MAY be "once flooded then done". In my testing wetting a 1" segment that has not happened, a little drying and it stops tripping the sensor; even if it does die, at this cost it's a reasonable consumable.
