Hi again Phuturist 
I solved the problem, thank you for your help, i tell you what happened (it can be useful for other users).
So firstly, I tried to repair my EM to homey. if this is the default setting, I thought this will solve the problem, but nothing happened.
As a next step, I created a flow for this as you said, but still nothing happened.
because you said, the device has this function, I started to search in the settings, and i found a solution.
first, I went to the devices - EM - Settings - advanced settings, and I set the “Include in total” as “yes”
After this, i went to the energy tab and i check again the EM’s settings here. I was surprised, but i got a new setting here.
i Turned it on, and the problem was solved
And yes, i’m using a HP2023 with the beta app, but it’s working as i see 
Thanks for your help again (I contacted you about the robot vacuum at the end of last week)
Have a nice week
Tamas
