The technicians at iFixit got their hands on an Elster Rex2 Watt-hour meter with features that an old-fashioned motor-driven meter lacks: nonvolatile memory with 1 million write cycles, advanced security with full 128-bit AES (Advanced Encryption Standard) encryption, the ability to make remote upgrades, and support for 900-MHz and 2.4-GHz ZigBee communication. The meter can also track overall power usage by time, which raises privacy concerns for some utility customers. On the other hand, some customers welcome the ability to parse their power usage to better manage it and, they hope, save money.
