HI,

Did anyone did or did try to interface a ISO BOOST Transformer with a GX device to get Shore power Input info? Some like the ASEA DBT12 have RS485 interface. The GX device can interface with some RS485 devices to get powermeter data. I currently do not have any Info regarding the ASEA Protocol. So I am wandering if anyone had done it? If so any pointer, detail you would like to share? Any other product Similar to the ISO boost that would directly interface with the GX ecosystem?

I think there is a standard set of registers that Modbus power meters use for their interface.  
Find a meter compatible with the GX, and look up the register set.  
Otherwise, you should be able to get Node red to read the custom register set over RS485, and to insert these values into the correct d-bus service.
