Hi
Does anyone have experience with electricity sub metering?
I am basically looking for a keypad system where one can punch in a number to load units. I would like to manage the vending myself and not use some online service which charges a monthly fee.
The system doesn't have to do any other bookkeeping. A pre-printed list of vouchers per device is also a possibility.
I had a look at a system from acdc.co.za which works with a smartcard. The system is in chinese-english with a non user-friendly interface.
