Hello, I am new to this, I have installed sdr and rtl software following the help guide, I have solved some inconveniences due to the difference in folder locations, but when I start the weewx I have this driver load error. could you please help me, thanks

Weewx is not finding the driver you have specified in weewx.conf

The "differences in file locations" you mention is likely the cause.

What is your driver setting in weewx.conf ?

Where do you have the driver(s) installed ?

 

[Juan EC7D]

thanks for answering my question

The driver configuration in weewx.conf is:

SDR]
    # This section is for the software-defined radio driver.
    # The driver to use
    driver = user.sdr
    #path = /home/pi/rtl_433
     cmd = rtl_433 -f 868M -s 1024k -M utc -F jons
     #path = /opt/rtl-433/bin
     #ld_library_path = /opt/libusb-1.0.20/lib:/opt/rtl-sdr/lib
[[sensor_map]]

       outTemp = temperature.*.FOWHx080Packet
       windSpeed = wind_avg_km_h.*.FOWHx080Packet
       windDir = wind_dir_deg.*.FOWHx080Packet
       outHumidity = humidity.*.FOWHx080Packet
       rain = rain_mm.*.FOWHx080Packet

this is what appears now in weewx load tracking:

The drivers are installed in:

/home/pi/

any other suggestions?
Thanks.

> driver = user.sdr

This means weewx expects the driver to be in /home/weewx/bin/user (if you're using setup.py to install weewx)

There have been other threads recently about this saying how to put the driver in other locations.  I think the 'path' variable might help there, if you really want it in an unusual location.

Hello Vince, thanks again,

I had already noticed the wrong location, but that is where the driver installation program created it, I copied it and pasted it in the correct directory / home / weewx / bin / user /.
Now load the driver but an error still appears

failed to start process 'rtl_433 -f 868M -M utc -F json'

I enclose a list of start log
