Like I said I can't explain why this error would not come up with the same
driver under 3.9.1,I just checked the 3.9.1 documentation/code and
hardware_name was mandatory. In any case easy fixed, you just need
something like this in your driver class:
@property
def hardware_name(self):
return "MyDriverName"
Fileparse driver
<https://github.com/weewx/weewx/blob/master/examples/fileparse/bin/user/fileparse.py#L111>
is a good simple example.
