Houses are mostly brick, wood and/or concrete, but that doesn’t mean they can’t be smart. With the right bit of technology, you can enhance the efficiency, convenience and security of the place where you and your family spend most of your time.

And right now you can save big on four smart home accessories. From easy water monitoring to tougher door locks, they’ll give your home a real boost.

Flume Smart Home Water Monitor – 27% off

Monitor your water usage with an easy-to-install sensor, Wi-Fi bridge and iPhone or Android app. The Flume Water Sensor straps around your water meter and sends real-time water usage information to the Flume Bridge, which connects to your home’s Wi-Fi so you can access your water data from the cloud. You’ll get real-time notifications of leaks and water usage from anywhere, at any time.

Haven Connect Lock – 15% off

Deadbolts are standard locks on our doors, but that doesn’t mean they’re the strongest. The Haven Connect Lock is rated as much as 10 times stronger than the standard deadbolt, with a flexible locking wedge that uses an intruder’s energy against them. You can control it by stepping on the pressure-sensitive locking pedal, or via the included app, so you can share digital keys with visitors, monitor access, and more.
