[Insights] - Spikes in reports

In the insights reporting I occassionaly find spikes in the report like displayed below. As I download the data for tracking energy consumption it disturbs the results. Is there a way to resolve this?

Trying to do
View/download energy reports of devices like Coolcam and Fibaro plugs

How to do this
Select a powerplug that tracks energy consumption. Filter a period of time

Expecting to see
Regular incremental line of power consumption

observed result
Spikes over 2 million A or Kwh value
