VRM Portal extWrong values in VRM about solar generation

Hello everyone!

I have a 12v installation comprising of 2 x 100/50 Blue solars,1xEpever tracer, 1700w of panels, 1 multiplus 12/1600/50-70 and a lifepo4 of 230A.

All items are connected to Venus OS - latest version- by usb to ve direct cables and the epever reports with custom python script in dbus. All values are logged and are sane upon inspection.

Despite the values being ok upon inspection, VRM portal values about solar generation are off by an order of magnitude. To add to the confusion the VRM's projected solar values are ok-ish.

Is there any way to capture the values off the Victron BlueSolars going into VRM?
Any advice at all as to why this is happening?

Thanks in advance.

After some investigation in the python code that populates dbus for the epever solar charger (https://github.com/silios/victron-json-mppt Ganey's abandoned project now updated to work with Pi4 /Venus OS 3.1/python 3), it appears that default values where triggering some miscalculation on the VRM.


Values in the export are the same, but instead of defaults (zero values) i intentionally omit power yields altogether if the query to epever is unsuccessful and that seems to have fixed the problem.
