This is happening when using the VRM and downloading the multiplus setup
this started to happen on firmware 487, with a VE BMS assistant installed - But the ve-BMS was unplugged and I was trying to do a remote update/upgrade the fw to 489 but this stalled at 20.5%
thinking it was a remote upgrade issue - I have done the below
so now I have manually upgraded the firmware to 489 by going to site. thinking this would fix the issue
we have a cerbo connected on 2.80~24 (also connected to the VRM)
we have one VE-BMS connected
there is NOW no assistant installed as 489 FW does not require it with the new tick box ticked and the ve-bms is working correctly as when I unplug the VE-bus cable from the VE-BMS the inverter shows low bat and switch's to pass through as it should.
so everything is working on site and the vrm and remote console is working but I still get this error : Error: mk2vsc-33
but the below error still occurs when I try to download the setup
Anyone got any ideas as to how to overcome this issue
The secound battery monitor is a 123smart BMS
