Energy dashboard calculation feature

Feature needed to calculate power or energy.and show in energy dashboard.

Today I have in my case some shelly devices which are measuring current.
Nr. 1-3 in the following example are measured by the devices itself. For Nr. 4 i need a calculation and show the result in the following way.

1 Total energy consumation (from shelly) 20 KW
2 Heating energy consumation (from shelly) 5 KW
3 Oven energy consumation (from shelly) 7 KW
4 Calculated varius devices energy consumation (Total-Heating-Oven) 8 KW

I’d request a feature request that I can configure it directly without using yaml code or template sensors and show it like in the example.

As explained in your other topic, those are power sensors (kW) not energy sensors (kWh). The energy dashboard uses energy sensors.
