Add a new view where you can select an entity, a time range and the type of statistics (long term, short term, states).
The data is then displayed in a table. Columns are at least Timestamp, Value, Min, Max, Mean (Or whatever makes sense) . A button can be used to edit a single value.
With a “bulk editor” all values can be corrected by means of operators (+, -, *, /, None) and value.
Example 1:
- Operator = *
- Value = 0.1
- => All values are multiplied by 0.1.
Example 2:
- Operator = -
- Value = 123
- => All values are subtracted by 123.
These changes are only applied with “Apply”, so that several operations can be completed before all changes can be applied. Or, if necessary, discarded.
The icing on the cake: If the shot term is corrected, the long term is recalculated.
