Product

ShowerStar is the highest impact and lowest-cost water and energy efficiency measure available, teaching and nudging people to take 4 minute showers on a daily basis.

A patent pending, simple DIY retrofit product that mounts onto an existing shower pipe or shower-head and that automatically detects when a shower starts.

Once the sensor detects a shower has started, a timer starts and simple "Traffic Light" alerts remind the person showering about their shower time and when its time to get out.

ShowerStar is powered via a long life rechargeable battery with a USB type C port for charging from a standard USB charger. The battery lifespan is ~6-8 months depending on use and configuration*. 

2 mounting cradles support mounting onto virtually any type of shower.

Forecasting savings

Once you've entered your city or state, cost of water, type of water heating heating technology, cost of energy and the flow rate, you can use the forecasting tool in the App to determine what your savings would be by reducing your shower times.

The App displays water savings, energy savings and total cost savings.

The formula for these savings calculation was developed independently and details can be found here.

Utility Portal + Dashboards 

ShowerStars upload non-personally identifiable usage data from each device to the App and then periodically to the TouchGrid Portal. This permits utility program managers to verify their device installation, persistance and  showering behaviour to inform program design and for EM&V.
