* Generic Modbus energy meter
*
* - Supports single three phase device or three single phase devices of same model on bus.
* - Uses a rule file called modbus allowing for easy configuration of modbus energy monitor device(s).
* - For easy configuration of modbus energy monitor device(s) use:
* - a rule file called modbus
* - a filesystem file called modbus.json
*
