 As {options} you can use:
 
-    --addconversions=<unit>+ add conversion to these units to json and meter env variables (GJ)
     --alarmexpectedactivity=mon-fri(08-17),sat-sun(09-12) Specify when the timeout is tested, default is mon-sun(00-23)
     --alarmshell=<cmdline> invokes cmdline when an alarm triggers
     --alarmtimeout=<time> Expect a telegram to arrive within <time> seconds, eg 60s, 60m, 24h during expected activity.
