Tag Scaling in Groov


I have certain devices which use 4-20 mA for their output. These are connected to pumps which don’t run all the time. When the pump is off there is still a certain amount of current fluctuation which manifests itself as small numbers in the display. Is there a way to “zero out” these tags if there’s nothing going on? I suppose I could do it in a strategy but I would have to rework everything as these are being pulled direct from a modbus device by Groov.
