I would like to use second GX device in system, but I need to use some data from first one. Is it possible to get for example battery current form first GX device and set it on second one as com.victronenergy.system Battery Current (841). I have noticed that there is new setting "ModBUS TCP Devices", but when I setup connection the result is
On MASTER
and
on SLAVE
Or maybe other sugesstion for data synchronization ?
