 - **impPerUnit**: integer, normally 10, 100 or 1000, used for calculation of momentary units
 - **unit**: free text, but only ``A-Z a-z _ and -`` should be used. Used for MQTT topics ``Yesterday__unit`` and ``Today__unit``

+- **readingType**: text string - used as topic name in MQTT output if defined, otherwise subtopic name = "reading"
