On CANvu VE.bus device (a Multi) does not appear

Hi! I tried multiple firmware pairings like:
2.33 - 460
2.33 - 433
2.30 - 433

I tried multiple utp cables, but I can't get the multi device to show up.

I have shell access and see something like this, not sure if relevant:

root@canvu500:~# cat /data/var/lib/mk2-dbus/mkxport-ttyUSB0.settings
  D       Multi - Inverter / Charger                                                                                                                    Multi - AC Input  


The vebus values don't appear on dbus. The system has a bms with assitrant installed and digital multi control. With the stock setup I think it managed to see the multi but never since


Any help is really really appreciated.

the strange this is that if I add an usb-mk3 interface, the app starts automatically:

Hi! @Daniël Boekel (Victron Energy Staff) can you please ask around if anyone experienced something similar. I will have SSH access so I can debug on sw side. The strange thing is that the mk3-usb dongle works.

really appreciate it

No, only by using a mk3 device over usb instead
