[Ovmsdev] Notifications Framework (subtype and filtering)

I see the PIN code there.

Probably ok for the moment, but I’m thinking that in general it would be good to have that vehicle pin code stored in the password config store, protected and available to all vehicles. We don’t need multiple vehicle-specific PINs in the one module.

Then, if defined we should use it to verify PINs locally before sending to the car. Privileged commands (such as scripts) could send it directly. We could also implement some protection in those basic commands again brute-force attacks. These pins are a real weakness is vehicle security systems.

Regards, Mark.

Implementations can also override the individual Notify…() functions to disable particular notifications, or customise the output. For example, a Tesla Model S module may want to override NotifyValetHood() and send the alert as ‘frunk’ rather than ‘hood’.

It seems that this can be done in the vehicle.{h,cpp} framework in a standard manner, and work across all vehicle types. However, I guess that will break any notifications already being produced by other vehicle types.

>>> charge_mode=>stopped: Notify charge interrupted

>>> valet_mode=>off: Notify valet mode disabled
