Presently, the only way to get VE.Bus device serial numbers is to download the Remote VE.Configure file and inspect with VE.Configure / System Configurator.
In single inverter, systems, could we list the serial number on the Device List in VRM and "Device" in remote console?
For parallel, multi-phase or multi-phase parallel systems, perhaps we could have collapsed [+] listing like:
L1 Master: HQ210101xxxxx L1 Slave 1: HQ210101yyyyy L1 Slave 2: HQ210101zzzzz L2 Master: HQ210102xxxxx L2 Slave 1: HQ210102yyyyy L2 Slave 2: HQ210102zzzzz L3 Master: HQ210103xxxxx L3 Slave 1: HQ210103yyyyy L3 Slave 2: HQ210103zzzzz
