Vaillant Heatpump + missing Heating Circuits from config

Hi,

My system is slightly more complex than the average systems, hence I believe I'm facing some issues:

aroTHERM Split VWL 125/5 + VRC720 +2xVR92 + VR71 + 2 x VR70 + VR921
6 heating circuits are in place + an offtopic external gas boiler

ebusd is installed and HA add-on is running nicely:

issue:
it seems like autoconfig is not picking up 1 out of 2 VR70 and none of the VR92. Occassinally the scan picks up some signal under address ec and assigns a solar slave device, which is actually not existing.

Neither rescanning nor adjusting latency does not seem to resolve the issue.

ebusctl info response:

max symbol latency: 60
