My alarm system has the water sensors, so I use the ones that come from my alarm company. I think they were about $30 each with no additional monitoring charges. My monthly monitoring charge over cellular link, including smart phone integration is $25/month

But I think the sensors are only good if you are home or close to home.. If you are away on an extended trip, there is no substitute for just shutting off the water supply line into your house.[/quote]
How about a soleniod control valve after the shutoff valve, but before the regulator?

Plug it into a power relay connected to your house management system…

WiFi controlled dishwasher? – just thoughts… computerized home electronic projects….
