Best overall: Fibaro Flood Sensor

Fibaro's Flood Sensor offers the perfect mix of features, design, and price, making it our go-to HomeKit water leak detector. This completely wireless sensor runs on a single CR123A battery, which lasts for up to two years, and connects directly to HomeKit and your iPhone via Bluetooth. While limited in range, Bluetooth makes pairing to the home app fast without downloading another app or having to create an account.

Since the Fibaro Flood is wireless, all that is needed after pairing is to set it near one of the potential hot spots in the home, like under a sink. The Fibaro Flood Sensor takes it from there, monitoring the surface on which it rests for leaks with a set of tiny probes underneath. If water is detected, it can fire off an audible alarm and send a notification instantly. The best part of the Fibaro Flood is that it includes temperature sensing, which puts its measurements right in the Home app, plus it also has tamper detection that can alert you if it has been moved out of position. If you want a top-of-the-line product, this is one of the best HomeKit water leak detectors today.

Best value: Aqara Water Leak Sensor

If you already own an Aqara Hub, then the Aqara Water Leak Sensor is hands-down the cheapest HomeKit option on the market. Don't let its low price fool you, though, as Aqara's sensor is just as capable with onboard probes, notifying you the moment that it detects a leak through the Home app on your iPhone or iPad, and with an audible alarm with the hub.

The Aqara Water Leak Sensor also happens to be the smallest HomeKit water leak detector around, with it measuring just under 2 inches wide. The miniature form factor allows it to fit into the tightest of spaces, and since it uses a low-power Zigbee radio for its wireless connection, it can go up to two years in-between swaps of its required CR2032 battery.

Best coverage: Eve Water Guard

Unlike other HomeKit water leak detectors, the Eve Water Guard utilizes an external sensing cable that allows it to cover larger areas right out of the box. Eve's special sensing cable detects leaks throughout its entire length, which is around 6.5 feet, and it can be extended to cover a whopping 490 feet!

It's not just all about the cable, though, as the Eve Water Guard is also the only HomeKit detector that doesn't require batteries, so you will never be left wondering if it is keeping an eye on the home. Combined with Home app notifications, a powerful 100-decibel siren, and an on-device red flashing indicator light, the Eve Water Guard will ensure that everyone inside the home, and out, will always be in the know.

Bottom line

Water leak detectors are incredibly important for their potential to prevent a major flood. When it comes to Apple's HomeKit smart home platform, the Fibaro Flood Sensor is our top pick. Fibaro's sensor offers a convenient wireless design with great battery life, on-device alarms, and quick and easy pairing that doesn't require an extra app or account.

For additional protection, the Fibaro Flood Sensor also includes handy extras like temperature monitoring and tamper detection. Both of these are equally as important to protect the home. In the case of temperature sensing, it only adds to the overall value as it can be used in conjunction with other HomeKit accessories in automations.
