Brilliant - thanks for the quick reply!
So if i have got this right mine would look like this?
[processors.converter]]
[processors.converter.tags]
string = [“input kw”] # this is what my string field is called at the moment
[processors.converter.fields]
integer = [“power in kw*”] # this is what my string key would now be as an integer in the table
tag = [“PowerInToDC”] # this would be the tag i would use to select the metric in Grafana?
