# Parameter `Field`
Default Value: `undefined`

Dedicated definition of the field for InfluxDB use for saving in the Influx database (e.g.: "watermeter/value").

!!! Note
    If you edit the config file manually, you must prefix this parameter with `<NUMBER>` followed by a dot (eg. `main.Field`). The reason is that this parameter is specific for each `<NUMBER>` (`<NUMBER>` is the name of the number sequence defined in the ROI's).
