Meet leakSMART: a smart home kit with an automatic water shut-off valve, leak sensor, hub, and everything you need to protect your home from water damage. The leakSMART valve connects to your home’s main water supply and shuts off water in the event of a leak. You can pair it with Wink, IRIS, or Zigbee based systems to receive notifications quickly.
The companion app for this system is available for iOS and Android devices. The kit is available for under $400.
