@Bluemu yes, it’s definitely possible to use multiple SmartShunts connected to a GX device to monitor individual loads.
Therefore, via VictronConnect under Misc set each to “DC Meter” and select “Generic Load” or any other appropriate load type. There are more options if you scroll down. The SmartShunts will then show up on the GX device under “Devices” and report the DC consumption.
With the upcoming release of Venus OS v3.70 you will also be able to access an overview conveniently from the gui-v2 Overview page by tapping the “DC Load” tile.
