[Ovmsdev] Roadster: Some alerts not showing up

[Mark Webb-Johnson]

The server doesn’t have any per-vehicle configuration (other than authentication), so not sure how this could be easily done server side.

A kludge might be to pickup the notification event in a javascript on the module, and then raise a new different textual event for specific IDs - but not sure if the vehicle module javascript framework gets enough about the raised notification in order to do that.

An alternate kludge would be to manually list vehicle IDs to be exempted from the DMC policy in the ovms_server.conf file, and have code to check that in ovms_server.pl.

But, that said, I’m not really sure why we would want this. Our goal has always been to mirror what it says on the little VDS in the car, and that doesn’t show these debug-only alerts. 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?

Regards, Mark.
