Energy Meter VM-3P75CT Stopped Working After Update to FW V1.11

After updating the firmware of the VM-3P75CT, which is used as grid meter in my ESS, the GX device does not recognize it as grid meter any more. In VRM the grid meter just shows “-”. In VictronConnect I can still see the device via the VRM and it seems to display the current power consumption in all three phases. It is still configured as grid meter.

The VM-3P75CT is connected via VE.CAN. Up to the firmware update it worked pretty well. I don’t know the firmware version before the update, but it was probably the latest version distributed via VictronConnect. Where can I find older firmware versions just to quickly fix my ESS? I think it is possible to upload dedicated firmware via VRM or VictronConnect.

Thanks in advance!

Just found, that end users may get access to Victron Professional now. In the FW changelog for the 3P75CT it is mentioned, that FW>=1.09 require Venus OS V3.60 or later. So I downgraded to V1.08 and everything is working as before.

Sorry for the noise! However this info might be of interest for others as well…
