Here's the log...what am I doing wrong?

I'm having issues with weewx-sdr...any help appreciated

I can run rtl_433 manually and see my sensors out there....but when running weewx I get this error message:

root@raspberrypi:/etc/udev# systemctl status weewx

[Tom Keffer]

I'm not seeing the log. Just the status output from systemctl.

There are many threads about this error in weewx-user. Here's one. Try the suggestions in that thread.

Hello Charlie,

Don't you have in weewx.conf ,[sdr] section, a "sudo" at the beginning of your rtl_433 command line ? If yes, try to remove it.

That fixed the problem in my case

Yes, you have a permissions problem. Try the suggestions in the thread I linked to earlier.

Also, take a look at the wiki article Understanding permissions, in particular the section Example: add the weewx user to group in a udev rule.
