Data offsets
When there is a step in the data, which you wish to remove, a dated calibration can be applied. When a dated calibration is used, all readings after this date will use that calibration factor. Multiple dated calibrations can be used if there are multiple steps in the data. This can also be used for a sensor being replaced when you may also have a change of the calibration factors for the new sensor.
Adding a new factor
Create a new factor and add it to the formula in the Blueprint. Any name can be used as long as it is not the same as an Input or Output.
Update the factor on the sensor adding a zero value for the first period and a dated offset to remove the step in data. The offset will need to be calculated from the difference between the reading before and after the step.
If this has been calculated correctly this will remove the step in the data.
Note: Set this factor in all sensors calibrations or the formula will not calculate. In this example all other sensors using this Blueprint would have the calibration factor "offset" set to zero. This only needs to be done for the default factor as a dated one is not required unless you are removing a step in the data.
Multiple steps
If the data has stepped and returned for a known reason, multiple dated calibrations can be used to align this with the previous data.
