I have a few places in my home that I really, really don't want water to be. I've had bad experiences with water in the past (read: whole-house flooding from an upstairs toilet valve), and I'd like to make sure I can catch a slow (or even fast) leak before it becomes a huge pain.
There are a few places that I'm suspicious of, namely a couple sinks, the line running into a refrigerator, etc. We currently have some water alarms that beep when they detect water, but that won't help much if I'm not at home and thus can't hear the beep.
What's a reliable, long term, cheap way to get notified (SMS, push notification, IFTTT action, etc) of a water leak?
