ESS; GX Error #49 - Grid meter not found

Q&A and troubleshooting

Hi all,

I just finished my ESS system build:

  • Multiplus II
  • Cerbo GX MK2
  • VM-3P75CT - connected via Ethernet
  • Lynx Shunt VE.Can

I configured system as ESS (adding ESS assistant).

I now get an error GX Error #49 - Grid meter not found. In ESS setups with External Grid Meter selected, no meter was detected.

Multiplus is in passthrough mode (because it cannot find the grid meter)

The VM-3P75CT is visible in VictronConnect (local)

The VM-3P75CT was visible in VRM, before I added ESS assistant.

The VM-3P75CT is not visible anymore in VRM. Not sure anymore if this happened after I added ESS assistant or after I updated the firmware.

All devices are on latest firmware.

I have powercycled all devices.

Any clues how to fix this?

Thanks!
