[weewx-user] sdr.py not parsing Oregon WGR800X output correctly.

['Rob Series' via weewx-user]

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

ALSO

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.

[weewx-user] sdr.py Fine Offset WH32B sensor

[steepleian]

RTL_433 was updated today to include the Fine Offset WH32B sensor on the -R 
78 switch.

I have updated accordingly and now able to see the data stream when running 
from the command line.

However, thus far, I have not been able to map the packets correctly with 
the sdr.py driver. Has anybody else had a chance to look at this yet and 
come to any conclusions?

[weewx-user] sdr.py

[Brad Tucker]

Trying to install weewx. I have installed rtlsdr rtl433 along with weewx.

I have tested rtf-433 by issuing rtl-433 -G and get lots of data passed 
back.

Once I try and use the actual sdr.py driver directly using the command:
sudo PYTHONPATH=bin python bin/user/sdr.py

I get this:
Traceback (most recent call last):
  File "bin/user/sdr.py", line 699, in 
[--path=PATH] [--ld_library_path=LD_LIBRARY_PATH]""" % DEFAULT_CMD
ValueError: unsupported format character 'p' (0x70) at index 1

Not quite sure where to go from here. Seems maybe I need to call a path out 
to the driver.

I have tried things like this:
export PATH=/usr/local/bin:${PATH}

export LD_LIBRARY_PATH=/usr/local/lib


from the shell and then issuing the command. Im a bit of a newbie here so any 
help would be greatly appreciated.


Thanks,

Brad
