[Ovmsdev] Roadster: Some alerts not showing up

Chip,

Good suggestion, But unfortunately we haven’t been able to find that signal on the can bus. I suspect it is never sent, but just entered and stored in the VDS; as the vms sends debug alerts regardless of the setting. The alert message strings are in the vds firmware, and vms only sends codes.

To do this properly would require ovms doing what the vds does - have an alert code -> debug/user,message table and do the conversion and filtering there (not in the server). But that is quite a bit of code flash memory.

Regards, Mark

I would note that if the goal is to have OVMS show what the VDS shows, if you have the Roadster set to “Show Debug”, then OVMS will not show what VDS shows.  Is it possible to track the status of “Debug reporting to VDS” in the car, and have the OVMS server relay accordingly?

The solution we have is not perfect, but it does avoid the worst of them. I have received so many support questions and concerns from roadster users of OVMS asking about these over the years - Tesla is aware that they false positive so labelled them as debug-only, so why would we want to bombard the user with these alerts every time he drives/charges the car?
