How use getWorkflowStaticData

Hello her, it’s my first topic ! I use this simple workflow to parse list of object and use an api to collect information about electrical consumption.
I want to keep the total consumption send by the api and to the next run of the flow (every 1 hour) i need to compare the old and new value, if the difference < 4 i need to send an email alert.

I need to store for each item the value of “total_elec” and use it one hour after the last execution of the job.

I parse the documentation and i think i can use the getWorkflowStaticData

But i don’t understand how ?

@Tom_E , this post provides a workflow explaining how the static data could be used. You just need to adjust the usage to your needs.
