This one has probably been around and been given a thumbs up in prior ratings....but I'm convinced Sinope did this one right; made it perfect for the base of a "water wall" in a kitchen or elsewhere and made it so it just sips power.
BUT IT'S SIGNIFICANTLY overpriced...that is until you have a leak that it catches.
Neo Coolcam w/pigtail. Its pigtail sensor allows multiple different use-cases for placement of the main puck and the remote sensor, and @kkossev's excellent driver is available.
You can even extend the pigtail sensor length if you need a longer run using a cheap 2.5mm audio cable extender (I added a 25' cable to mine to reach a remote steam generator in the attic). Available on Walmart and Ali:
Aqara water leak sensor. One of the few sensors that makes it easy to add external sensing connectors. I use them with pressure pads & float sensors & they work like a charm. Even stay connected to HE unlike many of their Zigbee sensors.
I like my Zooz Titan valve. It can have battery backup, can periodically exercise itself, is very easy to install, has freeze and water sensors built in. Plus, it's Z-Wave.
Moen Flo. May not be officially integrated, but the community integration works well and has allowed me to use HSM with my variety of leak sensors to control the valve, rather than needing to purchase the expensive and very large Moen WiFi leak sensors.
Zooz ZSE42 Leak Sensor.
It is tiny 1.9” x 1” x 0.3” and gets about a year of battery life out of a single CR2032 battery. My one complaint is that they are not dog resistant! I have had a couple of them chewed up by my dog who finds them behind a toilet. They both continue to work with a chewed up corner, though,
They have updated it with an 800 series Z-Wave chip but I don't have any of those. It is slightly larger and uses a CR2450 battery and is IP66 water rated for some outdoor applications, although I doubt the water resistance would stand up to my dog's teeth!
Pricing is good compared to many other sensors, List price is under $30 but I bought most of mine during a black Friday sale for under $20 each, but usually are available for under $25. I pair it with the Zooz Titan water valve (also highly recommended) in HSM to protect against a major water leak.
Ha, I have a dog-chewed Z42 too -- it was the only one he could access pretty easily (behind washing machine), and he sure enough found it... Still worked overall, but it started ripping thru batteries fast after that
I recently replaced my Z42s with the newer model -- much better waterproofing and the bigger battery is welcome. Due to those 2 things, it is slightly larger than the original.
I doubt it's much sturdier in the jaws of a labrador, but I now have that one blocked off better too.
