(Where's the best place for device introduction/discussion? This doesn't seem like it.)
This sensor paired like bread & butter, even has Hubitat listed on the side of the box. Nice ! Seven feet of water sensitive cable that responds to water anywhere along it, and tracks under-sink temp too!
Route it along the floor and up through the bottom of cabinets along that "line-of-leak-risk" in your kitchen (sink, dishwasher, frig, etc). It's not cheap, ...but when you consider it's sensing water along every bit of the cable that equates to a lot of rapid sensing that you'd otherwise have to set multiple sensors to sense (or wait on a "growing puddle" to sense with a single spot sensor).
If this sounds like an advertisement; let's just say that I'm excited that it paired, grabbed the right driver, and so far works without a hitch. Thanks HE Folk for your working relationship with SinopƩ.
