Thanks @Troon. Looks so easy when you say it like that
I wouldn’t know how to code this.
But I’ve seen Ruurd Sanders [ruurdsanders] share a code similar to what you are talking about, in the topic " How to SUM 3 Shelly phases of Consumption and load in Energy Dashboard?"
However, his code was about energy (when I need power).
I’ve contacted Ruurd, if he doesn’t reply to me, I’ll try replacing parts of his code with whatever makes sense for power/load.
