ReMeter record your own exact usage of total power consumption on the the prepaid meter.

Say for example at the onset everybody contributes 5k. When the unit is exhausted, you have only used 2k, that means someone has used your 3k. So on the next contribution you will contribute just 2k and the person who used your 3k will contribute more

ReMeter let you know your own exact power consumption from a pool of shared prepaid meter
