Water leaks are more than annoying calls to the plumber. They can cause massive, expensive problems if left undiscovered, including serious mold problems. Those dangers grow worse in winter, when freezing weather can cause pipes to freeze and burst. That's hard to keep track over, except for one small smart home device to the rescue: the humble but powerful leak detector.
Leak detectors connect to apps on your phone and warn you exactly when a leak occurs, no matter where you are. That lets you take fast action at home, from shutting down water to toilets and sinks to raising temperatures to prevent freezing conditions from getting worse. Basically, I think every home should have one.
I've tested more than a dozen leak detectors to find my favorites. Here are the fine products I recommend.

What's the best leak detector?
Leak detectors, especially battery models, can go nearly anywhere. Eufy
The best leak detectors we tested all performed accurately with reliable connections that didn't drop. But one model particularly impressed me with its dual-function ability to detect both freezing temperatures and the presence of puddles. Eufy's smart detector is at the top of my list for this reason, especially for those who may worry about frozen pipes. If you'd like a leak detector that doesn't require a hub, read on to see all of my favorites.
