EV Charger Modbus address not registered

Hi

I recently installed a Victron EV Charging station, close to an already existing Victron Solar installation (distance between Charging Station and Venus GX is approximately 15 metres)

The EV Charger works fine, but I could not connect it to the Venus GX. I did the Modbus TCP settings on both the charger page and the Venus page. when I go to the charger page I see all other components of the Solar system, But when I go to VRM I cannot see the EV Charger. there is an error message on the GX device, saying "Error processing function code 3, unit id 126, start address 40000, quantity 2, src 192.168.8.51: Modbus address 40000 is not registered"

How do I get this right?

I have attached screenshots for the error and the EV pageScreenshot_20220927_131855_com.android.chrome.jpgScreenshot_20220927_134328_com.android.chrome.jpg

So, after connecting the EC Charging Station to the same network as the Venus GX, It appeared on the VRM menu of the whole solar system, and I was able to update the Charging station's firmware.

Everything is working perfectly now, thanks to Lucian Popescu for the great support

Hi, are both GX and EVCS updated to the latest version?

The Venus is on its latest firmware, I could not get the option to update firmware on the EVCS page, and I could not also see anything on VRM. The EVCS is still on its default version.

I have a similar problem on my ESS system. Is it possible that we can get in touch somehow?
