Negative PV Power

I apologize, I see many questions about negative power but not one exactly like mine.
System - SmartSolar 100/20-48 connected to RPi VenusOS (Ve.direct USB cable). The Pi is connected to VRM but also locally to Grafana Docker. In both places, after sunset, the PV power starts reporting in negative values, -2 ~ -3 Watts

When connected to the controller directly via BlueTooth (phone), it shows a static 0W.

Is this -3-2W the controller self consumption? If so, how can I separate it so PV calculations aren't screwed up in Grafana (planning to keep 2 years records). Hoping there is a dbus value that does not include the controller consumption. I also think direct connect app and MQTT (VRM at least) should be showing the same thing. Right now they are not.
