I am configuring a Multiplus II.
VEconfigure3 allows me to load assistants when virtual switches are not used.
It is clearly stated in a popup note from VEconfigure3 that enabling the virtual switches and therefore the AC input control disables the assistants and vice-versa.
VictronConnect does not have a section for configuring assistants and allows to configure AC input control, even after loading the ESS assistant with VEconfigure3.
It seems that the two programs are currently not consistent?
It seems that VEconfigure3 should be used for the Multiplus configuration with assistants?
Some more background:
I wanted to configure under Linux.
VEconfigure3 is available only under Windows, while VictronConnect has a build for Linux.
Anyway, there seems to be some problem with VictronConnect under Linux. With Manjaro Linux installed on a newer Hardware, VictronConnect detects the Multiplus connected over the USB-MK3 interface. With the same version of Manjaro Linux installed on an older laptop, VictronConnect does not detect the Multiplus connected over the USB-MK3 interface. There is no problem with the detection of the Multiplus under Windows though (it is a dual boot system).
