Struggling with integrating power sensors to energy dashboard

Hi, I’m having trouble converting sensors exposing “mean power” in watts to energy sensors I can use in the energy dashboard.

I have several ELKO RF thermostats (floor heating) connected to Z2M that exposes a sensor called “mean power” that displays current energy consumption in watts. I’m having difficulty understanding how I set up a conversion to energy so I get the values in the energy dashboard, so if someone could explain it like I’m 5 that would be awesome :slight_smile: I’ve tried the Riemann sum helper but I can’t get it to be a selectable in the energy dashboard config.
