For its members only, Sam's Club offers the Samsung SmartThings Home Monitoring Kit, bundled with a Samsung SmartThings Water Leak Sensor, for $149.84 with free shipping. That's $88 under the lowest price we could find for these items sold separately elsewhere.

The kit allows you to control and monitor your home via your smartphone. It includes a SmartThings Hub, motion sensor, two multipurpose sensors, and a smart outlet. The water leak sensor sends an alert to your phone when it senses excess moisture and can trigger a light or siren when water is detected.
