Without knowledge of the full mypiweewxdriver.py it is hard to say, the
error is due to the accumulator expecting a (speed, direction) tuple but it
is getting a float, so I woudl suspect something funny going on with your
wind data. When I see outtemp when weeWX uses outTemp (case matters) I get
suspicious. Equally so when I see wind and winddir when weeWX uses windSpeed
and windDir. But then without knowing what is in self.label_map who knows.
I suggest you post the entire mypiweewxdriver.py.
