[Ovmsdev] How to remove temperatures from app?

Use:

ovms.{h,c}:
  signed char car_stale_ambient; // 0 = Ambient temperature is stale
  signed char car_stale_temps; // 0 = Powertrain temperatures are stale

Most common method is that every time you receive a CAN bus message with the temps (motor, pem, battery), set car_stale_temps=60 (or car_stale_ambient=60 for ambient).

Then, in your one-second-ticker function, just:

if (car_stale_ambient>0) car_stale_ambient--;
if (car_stale_temps>0) car_stale_temps--;

That will automatically signal them as stale after 60 seconds of no update.

Can you hold a few weeks for this? I am working on the Apps to re-work how we do the vehicle images. They are just too large (13MB+ already!), so I am working on a better way of handling the multiple colours and making it easier to add them to the Apps. Once I have this working, I'll let you know what format we need the images in.

Regards, Mark.
