Temperature sensors use the on-board EEPROM to identify which position to report in. This means that missing devices don't affect the logging.

Electricity consumption is logged using an IRQ to sample timer intervals between flashes. At the moment, there is no filtering on any of the sensors.

Readings are printed every 30 sec, or 5 sec in verbose mode.
