Is it possible to connect and monitor a 75/15 and a 100/30 MPPT controller on the Multiplus 2 GX?

It is two seperate battery systems but i want to monitor both systems in the VRM portal from home.

It is possible to connect both charge controllers to the MP2GX. One can connect with VE.Direct, the other one can connect via USB using a VE.Direct - USB cable.
You can view the each MPPT's data individually in VRM advanced page, but some values will be combined. For example, the overall energy yield for the day will be the sum f both controllers.
A single GX device and it's associated VRM site are meant to be one system.

The best way to monitor two different systems is to use different GX devices and therefore two VRM sites. A second small system can use a RaspberryPi as the GX device to keep costs down.
Connect the second MPPPT to the RaspberryPi with a VE.Direct - USB cable.
