changing / creating data for energy stati use

Hola,

still quite fresh in the stuff but can not accomplish a setup for an energy panel, properly, due to lack of matching / required entitities, but i have all i need just in a incompatible form.

Would like a overview of power [W] balance, taken, self made with a definable day switching time due to battery runs into the following day.
Same for work [Wh] and this with a day, week, month and yearly analyses, diagram ... THIS is the most interesting, as I and you usually pay for it.

Problem is to convert e. g. the given power into required work or make the overall work from shelly 3em pro usable for time periods and the like vice versa of tasmota smart plug.
First one is unsuitable due to accumulated work over the hole time into MWh.
Other way around i need to calculate work from voltage and current of a tasmota plug between inverter and grid.

There seems also a great great misunderstand at least at shelly about power and work. Shelly refuses or even doesnt recognise their "feature" in the "energy graphs" charts: displaying current relation BUT with work units.
NOTA BENE If a work graph's 1st derivate is negativ then there must be work / energy induced from somewhere into the system BUT I only need to switch off something and voila energy comes from ockmonek spaceship for free as the counted work is reduced. Work is also a contionously graph witho no sudden hops nor peaks like dirac pulses.
Maybe someone can apply a intrabrain syringe to them.

how to generate / convert a

• power data from current and voltage entitities
• work graph from power entitity over the time
• diff of entitity from time x to time y of a cummulating entitity like work for time based analyses
