Smart Showerhead to Help Save Water, Money

A series of Bluetooth-connected showerheads will give a light display when it's time to cut the long shower short.
The Hydrao showerheads have built-in LED lights that change from green to blue to purple to red based on how much water has been used.
Smart and Blue, the French company that created the showerheads, wants users to use the light as a visual cue to take shorter showers and reduce water and energy bills, CNET reported.
Hydrao First is available for preorder in the US (it's previously been available in France) for $99. Two other models—the $99 Hydrao Drop that fits onto existing showerheads, and the higher end, $160 Hydrao Loop—will be available later in 2017.
The Hydrao will also work with Alexa, Amazon's voice-activated digital assistant. It's a fairly limited integration—as Alexa informs how much water and money have been saved (if the user does shorten those showers, that is).
Hydrao's app can adjust the amount of water that will trigger each color. If the default settings are used and the length of showers is reduced, Hydrao First will pay for itself in a year—and then some.
