I've been looking into this lately for my own new home build. ?I have a client with the Phyn system that seems to be ok, but can be finicky. ?Much cheaper than the FloLogic, but I'm sure for a reason. ?I've looked at the Moen, but don't like that one as much. ?There was a cool one made by Guardian that clamps to your water pipe over a 1/4 turn valve and just turned the valve, super simple and seemingly effective, but there are rumors they are not really in business anymore.
?
As for integration, I'm not a huge fan of connecting something with so much potential to do damage to the house to our systems just for finger pointing safety reasons. ?But, Phyn does work with IFTTT, but not directly with Crestron as far as I've found. ?You could also hack one of their leak sensors and trip it with a relay to turn off the water, but it appears the only way to turn the water back on is through the app.?
