HomeKit Water Leak Detectors

The Fibaro flood sensor offers a perfect mix of features, design and price, making it our HomeKit water leak detector. This fully wireless sensor runs on a single CR123A battery, which lasts up to two years, and connects directly to the HomeKit via Bluetooth. Although limited in range, Bluetooth makes pairing with your home app quick without having to download another app or creating an account.

Because Fibaro Flood is wireless, all you need after pairing is to place it next to one of the potential hot spots in the house, like under a sink. The Fibaro flood sensor takes it from there, monitoring the surface on which it leans for leaks with a set of tiny probes underneath. If water is detected, it can trigger an audible alarm and send an instant notification. The best part about the Fibaro flood is that it includes temperature detection, which puts the measurements right in the Home app, plus it also has tamper detection that can warn you if it's been moved out of position.

If you already own an Aqara hub, then the Aqara water drain sensor is practically the cheapest HomeKit option on the market. However, don't let the low price fool you, as the Aqara sensor is just as capable with the on-board probes, notifying you when it detects a leak through the Home app and an audible alarm with the hub.

The Aqara drain sensor also happens to be the smallest HomeKit drain detector, with a width of only 2 inches. The small size allows it to fit in the tightest of spaces, and since it uses a low-power Zigbee radio for its wireless connection, it can go up to two years between required CR2032 battery swaps.

Unlike other HomeKit drain detectors, Eve Water Guard uses an external detection cable that allows it to cover larger areas right out of the box. Eva's special detection cable detects leaks along its entire length, which is about six and a half feet, and can be extended to cover a whopping 490 feet!

However, it's not just the cable, because Eve Water Guard is also the only HomeKit detector that doesn't require batteries, so you'll never be left wondering if it's eye-catching. Combined with Home app notifications, a powerful 100-decibel siren and a flashing red light on the device, Eve Water Guard will ensure that everyone in the house and outside is always up to date.

Bottom line

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

For added protection, the Fibaro flood sensor also includes useful features such as temperature monitoring and handling detection. Both are equally important for protecting the home. If the temperature is detected, it is only added to the total value, as it can be used together with other HomeKit accessories in automations.
