P R O D U C T   

The product has two parts:

 

TRANSMITTER : containing flowmeters, temperature sensors, and electronics.  Sends captured information to the display via RF / bus.    Optionally also to the cloud server.

 

DISPLAY : showing the water consumption and water temp.   The display, behind the mirror, remains invisible unless a tap is opened.  The flow consumption remains 3 minutes in the display after the tap is closed.  After this time the value is reset to zero ( but info captured is sent to the cloud server )
