I have a MP2 GX running ESS with the USB->RS485 Converter from Victron. This is connected to the ABB B23 Smart Meter which I need for running the ESS. (system is working properly)
I recently bought a Heat Pump, this also has a RS485 Interface with A B Wiring. I remember that I can connect multiple Devices parallel to the RS485? But they will need the same baud rate, parity?
The ABB Meter is connected with 3 wires, the heat pump has only 2 wires. Will this work?
I just looked at the ABB B23 Documentation, and cant find any info about setting a Device ID, but I think this is nescessary.
Or is it a better idea to use a second usb converter, does this work with a GX device?
Thanks for your help
