I've been working with someone transitioning from a Raspberry PI to Cerbo and he reported that Cerbo is not fully detecting a Multiplus which is connected through a MK3-USB adapter. The device shows up and the device's values populate, but those managed by system calk are not populating.
However, everything works after downgrading to Venus OS v2.94.
I found code in the multi.py part of systemcalc:
# If platform has an onboard mkx, use only that as VE.Bus service.
This appears to prevent use of a MK3-USB adapter with Cerbo.
@mvader (Victron Energy) This was obviously an intentional move but not sure it's documented anywhere. Was there a reason for this change? I know there were changes to the MKx interface as part of v3.0. Could it be that the MK3-USb can't be updated and is not compatible?
