Flood sensors might seem simple -- and on one level they are: they simply use probes to set off an alarm when they make contact with water, which increases the conductivity between them. But despite that relative simplicity, there's also a lot of room for creative design by the companies that make flood sensors. Some have water-sensing probes attached to their bodies, while others have cables with twisted probes embedded in them for long sensing range. And then there's Everspring.
The Everspring Z-Wave Wireless Flood Detector has a single wire that stretches about 8 feet, and at the end of it: a two-prong probe. While Everspring's $40 device certainly isn't as feature-rich as others on the market, it meets a very specific need, and does so reliably. The problem is, that need is too niche for most users.
Here are the Everspring Flood Detector's features:
Everspring doesn't have temperature or humidity sensing. It doesn't have tilt-sensing. Really, it has very few features to speak of, besides that long wired probe. Granted, that wire allows for easy monitoring of sump pump well water levels without letting water anywhere near the device itself. But is that feature alone worth $40?
Everspring's device has a bigger problem: it essentially does exactly what the Aeotec Flood Sensor does, but for more money. Although in rare instances having an 8-foot wired probe might be useful, for the majority of users, it's unnecessary.
While Everspring performs reliably, it simply doesn't boast enough distinguishing features to recommend it over more useful and affordable alternatives.
