Trigger event frames before start trigger

Hi community, 

 

I have a use case where I can an on/off pi tag that I want to trigger the start of an event with, but I want the event to start 2 hours before this occasion. My first version of this involved creating a new pi tag which offset the original trigger pi tag by 2 hours, so effectively if the original goes from 0 to 1 in 2 hours time, the new one would go from 0 to 1 now. 

 

This has the problem though of only working when manually backfilling, as when live, my new tag doesn't know what the value will be yet so no events get created.

 

What's the solution here?

 

Thanks,

Simon
