Hi,
Please could anyone help. I'm having problems using an Oregon wind speed
sensor using instructions on /weewx/weewx/wiki/sdr-rpi-recipe.
This was working, but following an upgrade from an old WGR800 to the newer
WGR800X it seems to have broken.
Output from sdr.py shows its getting the correct wind speed, but the parse
is breaking. The crazy thin is it works with my older WGR800 unit where the
input appears to be the same format. Is it possibly related to the \n
WEEWX SDR FILTER OUTPUT

If anyone has access to edit the sdr-rpi-recepie page, could the add
appropriate 'cmd' and 'path' lines to the conf file (or should thhs have
been added automativally by weewx_conf and the install script?
It took me some time to figure it out.
Many thanks for a great product.
