No - I don't think multiple rtldavis processes are normal.  Mine only shows 
one.

I would stop weewx and kill any rtldavis process(es) that still remain. 
 Sometimes they keep running unless you kill -9 them.

If you needed to use sudo manually then you probably need to add the weewx 
user to the correct groups to be able to attach to the rtlsdr dongle 
hardware. This might help if you wanted to give it a try.

#--- add weewx to all the groups typical 'pi' is in
# which should permit binding to non-privileged ports and typical hardware
for g in adm dialout cdrom sudo audio video plugdev games users input 
render netdev gpio i2c spi
do
  sudo usermod -aG $g weewx
done

Then 'sudo systemctl start weewx' and look at your logs for errors as 
always..

Re: [weewx-user] Re: New install rtldavis & weewx 5

[Pierre Decamps]

Yes complete path was full.
I tried adding sudo before the command in weewx.conf and it works !

Now I have two instances of rtldavis running, is it normal ?
