  * Sensor values are measured, actual values rather than target values.

- * Sensors are read once per second.  The sensor values are stored on D-Bus,
- * making them available to external interfaces like Redfish.

  * Sensors are read by executing actions, such as PMBusReadSensorAction.  To
  * read multiple sensors for a rail, multiple actions need to be executed.
