Riemann sum user historic data

I’ve wanted to start using the energy dashboard, but I only have Power meters, not Energy.
But I also want to retain the historical data that I have about the power consumption.
Is there any way to initialize the riemann sum helper with the already available historical data?

Creating a Riemann Sum sensor will not delete this.

No there is not, sorry.

Yup, I know it won’t delete it.
Sorry for my wording… by “retain” I’ve meant that I want to actually use it in the sum itself

Oof, that’s kinda :frowning: But thanks for the quick answer!
