My AC 2400+ is used with roof solar on its own inverter and uses a P1 meter to monitor flow to the grid. On the main page of the app, it correctly shows power going to the house, the battery and the grid.
If I use the 'Smart Meter Mode' energy plan, the app reports an 'unknown power source', being my roof solar. So clearly, it is able to distinguish it from what is coming from the grid, thanks to the P1.
Now, when opening the page of the battery system, it shows a graph marked: 'Input (From Grid / Roof Solar System)'. Technically, this is correct. From the point of view of the battery, that's the input power it received. However, I really want to know what part of that actually came from the grid, because that's the part I'm paying for. That information is not available anywhere in the app! It has the information available through the P1 data. So why doesn't it split the 'unkown source' (let me rename it to 'roof solar') and the grid?
