We spent 28 hours on research, videography, and editing, to review the top options for this wiki. Two of the most powerful reasons to turn your home into a smart one are safety and security when you’re away from it. But it’s not just burglars and fires you have to worry about; far too many houses have been damaged by slow leaks from plumbing or appliance malfunctions. One of these water detectors will offer you the peace of mind that your abode is as dry as when you left it.
