@Udo_Hartmann : Just a question from my side.
I want to get this value in Openhab:
I have 2 inverters (Symo 10 and Gen24), a Smartmeter and a Battery connected.
I created a “SUM” Group fpr the inverterchannels to get values of both inverters in one “group item”
This works well. But I’m not able to calculate 1,48KW shown in the screenshot above. The screenshot is taken at the same time the groups show this values:
"Verbrauch :" Verbrauch : 1789.3041
"Gridpower : " g_Fronius_Wechselrichter_Gridpower.state : 103.8
"Production Power : " g_Fronius_Wechselrichter_Productionpower.state : 1935.40
"Battery Power : " i_Fronius_Wechselrichter_Gen24_Battery_Power.state : -249.89
"Load Power : " + g_Fronius_Wechselrichter_Loadpower.state : -492.03
The Item “Verbrauch” is calculated in a rule:
Verbrauch = (g_Fronius_Wechselrichter_Productionpower.state as DecimalType).floatValue + (g_Fronius_Wechselrichter_Gridpower.state as DecimalType).floatValue + (i_Fronius_Wechselrichter_Gen24_Battery_Power.state as DecimalType).floatValue
Of course I read the binding documentation. There is stated, that the Load Channel/Item shows the current Load. But it is 492W in my example, which doesn’t fit to screenshot at all.
During night, when Battery is empty and no solar production takes place, the values are correct.
So my question is:
Which values do I have to calculate to get the red marked value in my screenshot above?
Thank you very much in advance
