Hydrao Aloé

Smart Showerhead


Hydrao Aloé is a showerhead that allows for water and energy savings using nudge technology.

The device acts on two different levels to deliver tangible savings: 1) Mechanically through a flow-restrictor that lowers the flow of a normal eco-shower and 2) behaviorally through the colored-LED sequence that informs users in real-time about their water usage and "nudges" them to stop the shower when the light turns red and so take shorter showers. Hydrao Aloé's behavioral efficiency technology engages users at point-of-use, providing them with real-time relevant and actionable information. No battery is required as the natural water flow drives a turbine to power the LED and data connection.
