I have a dual inverter setup from Huawei, the solar production takes the value only from one of them, even though I have both of them available in the properties ![1000033725](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/2/d2cf1b1bb6da6289e8cecbcb2e081e4fc67de25e.jpeg) ![1000033726](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/3/03fb49b30bd9e70232dbd1094263f58408a9fd9e.jpeg) ---

Is this an a app device or a virtual device? The energy dashboard only take measure\_power and meter\_power capabilities from the device - so only one yield because the others are subcapabilities then. Easiest would be to have two devices mit these capabilities. If that’s not possible, exclude your device from energy. Then create a virtual device and use the trigger on both measurements to sum up power and meter values from both yields into a virtual device with measure\_power and meter\_power. Then the virtual device must be set so device class ‘solarpanel’ to show up in the dashboard. Thats the theoretical way. You can try if the DeviceCapabikity app offers a device class selection. Then it should work this way. ---

The power production only reports the power pruduced and consumed, but not the power stored into the battery. Would that mean creating a VD device vs. the values reported from the app would be the solution? ---

It depends… For solar power the capability measure\_power from the “solarpanel” device is used. If the data is stored in another capability, you will get a wrong value. So it would be good to use this device only for grid in/out. Then use a VD with measure\_power for solar production. But this will only work if the current device doesn’t have device class ‘solarpanel’ then. I think you should ask the app developer (ist it SolarEdge app from Edwin?) ---

Many zhanks for your response! Yes, I am using Edwin‘s app. I will get in contact with him, but that will happen a bit later, as I am currently travelling with limited access to internet. Again, many thanks Markus
