Interface 1140 Firmware upgrade

Good Day


I recently installed to Multiplus !! in parallel with a PV inverter and an energy meter and I am getting two errors

One is low battery even though SOC is showing as 100% (Octo FX with CAN Bus communication with Pylontech batteries)

The second erro is

Error 15 - VE.Bus combination error


I intalled an energy meter and the problem started AFTER this installtion. How do I upgrade the firmware


many thanks

Where/how/when did you get an interface 1140? I can't find one for the life of me

I purchased an energy meter and I assume that its the 1140 interface device

It was purchased from a Victron agent in South Africa
