Which flood sensor will serve you best this winter?
Find the perfect device for your budget and home setup.
With winter around the corner, it's time to start thinking about protecting your home from the disasters that accompany cold weather. And that means flood sensors. We got together seven of the most popular devices to see which ones were the best deal.
All flood sensors work the same way. They have two or more leads that, when they contact water, detect higher conductivity. Then they set off an alarm and/or send your phone an alert. What distinguishes each device from its competitors is the extra features.
Honeywell Lyric Leak and Freeze Detector
The Honeywell Lyric Leak and Freeze Detector is one of the most expensive flood detectors out there. At $80, it measures temperature and humidity, works using Wi-Fi rather than a smart-home hub, features a loud alarm, and has a cable of twisted leads that extend the sensing range of the device considerably. Sadly, however, the Honeywell isn't waterproof and doesn't work with many other smart-home gadgets.
D-Link Wi-Fi Water Sensor
The D-Link Wi-Fi Water Sensor, at $60, doesn't rely on a smart-home hub like most of its competitors do. It also features a cable of twisted leads like the Honeywell Lyric. Its real strengths, though, come from not relying on batteries and working with IFTTT for cool smart-home integrations.
Everspring Z-Wave Wireless Flood Detector
The Everspring Z-Wave Wireless Flood Detector costs $40 and features a long, wired probe. Unlike the D-Link or Honeywell, this wire only has probes at its end, so it doesn't sense floods along its length.
Aeon Labs Aeotec Water Sensor
The Aeon Labs Aeotec Water Sensor is $35, but is otherwise almost identical to the Everspring. It's perfect for measuring water levels in a sump pump, but it won't work well under a sink or for monitoring larger areas.
SmartThings Water Leak Sensor
The SmartThings Water Leak Sensor is an affordable $40, but it has very few extra features to speak of. It works effectively, especially if you already use the SmartThings platform.
FortrezZ Water and Temperature Sensor
FortrezZ's Water and Temperature Sensor costs $48 and measures temperature. But it doesn't work especially well, and it has no audible alarm.
Fibaro Flood Sensor
The Fibaro Flood Sensor is one of the best Z-Wave dependent devices on the market. It measures temperature, alerts users in case of tampering, and even floats in water. It costs $60.
Every flood sensor offers users different abilities. For more in-depth analysis, check out this buying guide.
