Anyone successfully running weewx with weewx-sdr?

[Charlie T]

I have a mystery problem.....weewx runs fine in simulator mode and updates the html file regularly.  When I switch to using weewx-sdr I can see weewx call rtl_433 but the html file stops updating.  No errors posted in the messages file as shown below.  I'm thinking this is a configuration issue....somewhere?

fedora 36

WeeWX version: 5.0.2

Seasons version: 5.0.2

had to add weewx user to rtlsdr group so weewx could use it

You should check /var/log/syslog, not /var/log/messages. The latter usually does not include debug messages.)

This is almost surely a permissions problem. There are many threads on this topic. For example, this one. In that case, adding user weewx to group "plugdev" solved the problem:

sudo usermod -aG plugdev weewx

Also, see  the wiki article Understanding permissions. Pay particular attention to the section How to fix device permissions.

OK...well that's strange.  /var/log/syslog is NOT updating.  Even with a "chmod 777 syslog"...still no updates to syslog.

in general, redhat systems use /var/log/messages, debian systems use /var/log/syslog

systems that use systemd might swallow some or all of the system logging into systemd-journald, leaving you with nothing in /var/log/syslog or /var/log/messages.  if you are on one of those systems, then you'll have to use journalctl to view the log messages.

if you want to see the contents of /var/log/messages or /var/log/syslog without having to escalate privileges, you should change the permissions in the rsyslog configuration (/etc/rsyslog.conf) and/or logrotate configuration. i do not recall whether this is possible on systemd systems that have hijacked *all* of the system logging into journald.

your 'chmod 777' will go away at the next log rotation and/or rsyslog restart, and you really don't want to give world write privileges on system files like that anyway.
