This client was developed to run on a RaspberryPi with the official 7" touch screen. It uses the OpenSource FHEM-Server to communicate with remote controlled sockets. The sockets are switched on only, if a user has enough credit and are switched off again, when the washer is done.

• Use RFID Cards to identify users at the terminal
• Pre-Paid washing
• Detect end of program by measuring power consumption (=> vendor independent)
• Email- and push-notification when the laundry is ready
• Fixed price or time-based billing
• Fine-grained permissions
  • Special prices per user group
  • Deny access to a washing machine for a certain user group
