I have a Pi 3 running the latest version of weeWX 3.7.0 installed using
setup.py
It has a custom driver that is a combination of fileparse.py and Neville
Davis's piweather.py that is put in /home/weewx/bin/user
When I try and run weewxd from the command line I get the typeError.
I know it looks at the custom driver (called mypiweewxdriver.py) since I
had about 3 or 4 problems with mypiweewxdriver.py - mostly typos
I have everything set to software except barometer in weewx.conf, that is
[Calculations] and record_generation are set to software
I also changed the hilo for temperature to -55 and loop_interval to 2.54
I am sending outtemp, outhumidity, intemp, inhumidity, wind, wind
direction, radiation, barometer, rain - I am not sure why outtemp is 0.0 -
looking into that but that should not matter for the problem at hand.
It ran with the Simulator before the changes to weewx.conf
Should I be casting the wind and wind direction to int instead of float in
the mypiweewxdriver.py. Sure looks like it. Any idea how I could do that?
I know just enough to be dangerous but not enough to
figure out how to select wind and wind direction in _packet
