Modbus service com.victronenergy.settings

I have a Victron Quattro 48/10k with a Cerbo GX and 2 attached BYD Premium LV batteries.

With Modbus I can read a lot of data on the 3 services that are provided automatically:

  • com.victronenergy.battery (ID 225)
  • com.victronenergy.vebus (ID 227)
  • com.victronenergy.system (ID 100)

There are a few registers (i.e. 2705 max charge current) that I would like to read and change from this service:

  • com.victronenergy.settings

How can I add this service?

Thank you for the quick response.

This worked very well.

I can now use my Loxone server to see all data and modify some of them.

Hi @Gauding, it is possible to export your Loxone Cerbo GX Modbus Config ?
I have the same Config, but i can't read values frome Modbus.
Allways no Data.

Thanks very much.

Hi t-a-j,

I use three addresses and upload the template for each.

MB_Victron100.xml

MB_Victron225.xml

MB_Victron227.xml

I use port 502 to talk to the Cerbo GX (192.168.2.xxx:502)

Good luck!


mb-victron100.xml (1.4 KiB)
mb-victron225.xml (2.0 KiB)
mb-victron227.xml (756 B)
