Feature request: Possibility to define and log the result from a formula for a certain variable.
For example my wind sensor displays data in km/h. I would like to log this data in m/s, i.e. = / 3.6.
@Freddan101 - happy to help! Have you taken a look at Data Offset and Data Multiplier in the Properties pane of the Configuration tab for each variable being logged.
The actual value plotted on a chart is the value x [Data Multiplier] + [Data Offset]. The formula is applied after any aggregation calculation is made and your source data is unaffected.
In your case just set Data Multiplier to 0.277777777. You may also wish to create this as a duplicate variable with the units set to m/s so you can keep the original variable available should you need it.
So simple and elegant. The duplicate function is really useful as well.
A pretty calm evening from what the chart shows. 
Thanks a lot for this and your efforts with dataMine2.
