How to get Venus GX to show two LG resu 6.5 batteries at the same time

Hi All, we have an off-gird system using two LG resu 6.5 batteries in parallel with each other which is monitored with a Venus GX. The LGs also get tied to a large AGM setup at certain times of the day to share the charging. Overall the system is monitored and controlled by many Sonoff switches and a few Orange Pi's running a common bash script which works pretty well for us.

One very minor outstanding issue is the Venus GX only shows one LG battery at a time. If we unplug a canbus cable from one of the batteries, the VGX will show the other and vice versa, but the VGX will never show both at the same time. The VGX shows them both as Product: LG resu battery and Product ID: B004. Is it because they have the same product details? Do they need to be daisy chained rather than each connected directly to a canbus port on the VGX?

Its surprising the VGX can't tell it has two batteries connected to it..

@petekat03 Not sure if this is still an issue, but for info, RESU battereries should be joined using a RESU Plus, also LG Chem do not support RESU batteries in a off grid system, they must be grid connected.
