[Ovmsdev] GPS Logs (TWIZY) -- Future Feature?

[Mark Webb-Johnson]

Instantaneous power should be available in most cars. It is certainly there in the roadster (because we spoof it to show speed as a digital speedo).

It would not be hard to add it to the model and to the location streaming feature when an App is connected.

Regards, Mark.
