Hello,
I installed firmware version 3.60 on June 12th and since then I have encountered error #67 - No BMS.
The following observations have been made:

  • The error lasts for about 30 seconds.
  • Only one error is registered in the log, as if the system is restarting.
  • My HDMI display also seems to be restarting.

Hi @randy69,

The fixed for error 67 that were included in VenusOS v3.60 only apply to Cerbo GX MK2 when using the second VE.Can port for the BMS control.
That is quite a specific situation.

Now unfortunately, for older CCGX devices, there is the potential for VenusOS v3.60 to introduce error 67 alarms when previously the system did not have them. This is due to a CPU load issue, and has since meant we have rolled back that VenusOS Update for CCGX, and retired the CCGX entirely. More information about that here - Color Control GX - End of life - Victron Professional

As of right now, we recommend if you have a CCGX to roll back to v3.55.

As you mention the HDMI, it probably means you have a Cerbo GX, could you please post the VRM URL and I can have a closer look?

HI, thanks for the response. I am using a Cerbo GX, on which I have reset the firmware to V3.54. Everything works great with this version. Attached is a screenshot of the alarm log.
