[Ovmsdev] How to remove temperatures from app?

[Thomas Bergo]

Mark,

The code is implemented as your example, so the temperatures will be
indicated as stale by the code.

Is there a visual indication in the app to show that the temperature are
updated or stale? Now the app show the last temperature before the car was
parked/stop charging.

Regards, Thomas
