Wind direction not working using AAG anemometer over i2C

[gord hart]

Hi All

I have the system up and running using my old weather station from AAG. 

All the data is populating except the wind direction

The wind direction is the voltage type and was working on my OWW system that I am trying to replace.

Things stop on line 570 of OWFS with "a bytes-like object is required, not 'str'" as shown bellow.

I am using the driver with the Dallas support and I have looked at the code but it is above my skill level to fix.

Any Ideas?

Cheers

Gordon

Looks like you are using the forked code at...
https://github.com/glennmckechnie/weewx-owfs

I've tweaked that version with the following fix for python3

-

wd = w.split(',')

+ try:
+ wd = w.split(',')
+ except TypeError:
+ wd = w.split(b',')

I'm pretty rusty with weewx (and python), but I believe it should do the job.

Thanks very much Glen.

I will give that a try.
