I just updated my Multiplus II GX to OS version 2.87 from 2.73. I noticed that the GUI disappears shortly after a reboot. dbus-spy shows the "com.victronenergy.system" device constantly disappearing.
Some investigation revealed that this started as soon as I connected my MPPT chargers (via USB). After a factory default reset everything worked fine until I activated "Has DC System". Then it started crashing again, as soon as an MPPT was connected.
So it seems that having both a MPTT charger connectd and "Has DC System" enbled is too much for the system device. Is this a known thing and can I do anything about that?
