no solar history in VRM - actual mqtt-pv-inverter data is shown

Hello!

I'm using Cerbo GX with Multiplus II 5k and some pylontech batteries as ESS AC-parallel.

PV-Inverter is Kostal Plenticore on AC-In (parallel to Multiplus II). To see pv-inverter data in cerbo (and VRM) i'm using https://github.com/mr-manuel/venus-os_dbus-mqtt-pv .

Actual power is correctly shown on both (cerbo and VRM), but there is no (historical) energy data shown on VRM...

Is it possible to get this data added?

Hi @NordPV,

I think this is an issue with how that 3rd party code writes to the dbus. You're probably best starting a ticket in their GitHub and hopefully the author can resolve it.

There is a brief specification of what is expected here, looks like the AC/Energy/Forward kWh data is missing

Here is another implementation for different devices that I believe work correctly - https://github.com/victronenergy/dbus-shelly/blob/9b3696da597b41ab23e117b245cd09b9469157bd/meter.py#L95

https://github.com/victronenergy/dbus_vebus_to_pvinverter


But from here the solution should really be explored on the GitHub for the modification you are using, this is not a VRM issue.
