Hi,

I have a question about the validity of my configuration. I’ve installed the Shelly plugin and have a Shelly 3EM connected to my main meter. I also have several Shellys monitoring a small solar system. These are defined as “Solar Panels” in the Homey app. The Shelly 3EM occasionally shows a negative value on one phase. I’m feeding power into the grid. However, when I read the solar generation from the inverter in the evening, these values don’t match those in the Homey Energy app. What could be causing this?

Thanks

Moin,  
liest du die DC-Leistung oder AC-Leistung am WR ab ?  
Bei mir passt eigentlich so ca. die Angabe aus der DTU und im homey (Shelly-PM).

Der Versatz kommt durch unterschiedliche Abfrageintervalle.  
Das erste Bild ist aus der DTU, das zweite vom homey Shelly-PM.

Hast du bei beiden PV-Shellys so konfiguriert?
