Had one for a few years at my last house. It does awesome overall. Nightly pressure checks when you're asleep to make sure nothing is leaking. The only time I had issues with false positives was when something new happened that it recognized (first few times we used the water hose for the yard after installing, first few times we filled the bathtub after installing). The only real issue that I had with it was when the water softener would run in the middle of the night and that's on me. I set it on every 10 days (didn't need to cycle it before that). If I set it on every 7 days or something like that it wouldn't have been an issue.

Yes. Mine shut off the water because I was in the shower. I turned down the sensitivity, and now it won't come out of learning mode so every week it reports 0 gallons of water usage. No idea if it's actually working beyond showing water pressure.

I've had one for several years. Works great overall. My false positives are long showers at odd times and doing a lot with the hose outside randomly. I don't have sprinklers, but that is part of the set-up. I work on plumbing occasionally in my house and turning the water on and off from my phone is nice. Also, I was able to get a pretty decent discount on my homeowners policy with it installed.
