The 10 Best Smart Water Sensors
This wiki has been updated 10 times since it was first published in December of 2017. Two of the best reasons for turning 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; many houses are damaged by leaks from bad plumbing or appliance malfunctions. One of these water detectors will offer you the peace of mind that comes with knowing if and when a problem arises.

During this round of updates, we eliminated the Samsung SmartThings F-WTR-US, replacing it with its logical predecessor: the Samsung GP-U999SJVLCAA. Price was the primary motivation for this replacement, with the newer model ringing up at around the third of the cost of the older technology. We also liked that the GP-U999SJVLCAA showcased its ability to kill power to any connected SmartThings loads in the event of the unit entering an alarm state – but, it should be noted that this attribute is likely more to do with improved software, and less to do with improved hardware.
Beyond that, with the idea that potential for integration with existing smart home systems is only becoming more relevant to any home automation, we took a second look at previously ranked items, and gave a boost to those that boasted better compatibility. We also eliminated the Proteus WiFi – because it's expensive and doesn't include any sort of app, and added the Flume F1000 close to the top of our list.
Functioning much differently than other options we ranked for this category, the F1000 can be mounted to nearly any water meter (95% compatibility, according to the company), and monitors water usage for the entire premises in real time. While it’s incapable of checking for nuisance moisture in localized areas, like most these offerings will, it will notice any unusual water usage occurring, notifying homeowners via app of anything suspicious. If there’s one specific area you’re concerned about getting wet (especially if the source of water could be something other than utility, like say sewage backup or weather-related water seeping in from outside) than it might not be the choice for you. But, if you’re just generally concerned about the possibility of a burst pipe while you’re away from home, it might be the perfect choice for you. Its included app can also help identify ways you can reduce water usage, and help set up a water budget for your family.
