You’ll have to be a bit more specific than that.

Is it not drawing graphs at all? Are you getting NaN as values? Do you just not believe the numbers?

Try doing a manual polling of the device through the console, and specify the –d flag for debugging, and see what comes back, with an optional –r to have it not update your values.
