Domotic shower with wireless control panel

This project is thinked for all whit temperature/pressure water problems. It resolve 2 problems:

• it keeps temperature constant during the shower when hot water temperature chages.
• with a button press it drain out all cold water in pipes until hot water come to shower: then when you have shower you will have instantanely hot water. you can program the shower preparation when you want. for exaple u can set that the shower is ready for the 7:00 when you usually have shower before go to working.

To do this i think to buil two parts: the remote control panel and the built in wall part. They comunicate each other over RFID connection a powered by wireless power module with a battery.
