Current power from inverter?

Hi, I‘m using HA on a raspberry pi 4 and I also read via sunspec several data from my inverter (SMA Sunnyboy). But unfortunately there isn’t the current power😢 But it must be possible to get this data because another addon evcc is able to read and provide this data. In this case I don’t know how I could use it because the current power is integrated in this addon and I don’t know how I could intercept it.

Is there someone who is able to help how I get this data?

Is this a webconnect inverter?

Did you try the Home Assistant integration?
