Abstract

A remote meter reading system (10) includes a group of meter interface units in which each meter interface unit (12) operates between periods of activity and inactivity. The plurality of meter interface units (12) are assigned to groups, each of the meter groups having a sleep rate assigned. Upon reading each of the meter interface units (12), the sleep rate assigned to the meter interface units (12) in each of the groups is advanced to the next group's sleep rate. This process is cycled through all of the meter groups in the system in order for all of the meter interface units to have approximately the same amount of overall battery savings.
