Have it update a different item. For example, your source item could be “MiPlug1RawTemperature” and your final item is “MiPlug1Temperature”.
For one item or two items, this is very easy. If you anticipate more, look at the design pattern for associated items. You can name them appropriately, put them in a group, and get them all updated automatically. It makes sense if you anticipate more of these sensors.
