You would test it the same way as if you configured using /dev/ttyUSB0 for example. You just use /dev/weather instead of /dev/ttyUSB0. There is nothing special about it really. I just use this method as I have several usb devices on my server and I name them to reflect the application I am usin

What is a good way to test the symlink rule to verify that it was created correctly? There is the new file in /dev/weather but is there a more complete way to test? thank you On Tuesday, November 17, 2020 at 7:29:08 PM UTC-6 Greg from Oz wrote: > I set my fineoffset rule to: > > SUBSYSTEM=="usb

I set my fineoffset rule to: SUBSYSTEM=="usb", ATTRS{idVendor}=="1941", ATTRS{idProduct}=="8021", MODE="0666", GROUP="plugdev", SYMLINK+="weather" That way it is always /dev/weather regardless of the ttyUsb it is attached to. ll /dev/weather lrwxrwxrwx 1 root root 15 Nov 17 09:26 /dev/weather

Are you sure? Depending on what permissions the usb port has, you may need to use sudo to run lsof: *sudo lsof /dev/ttyUSB0* Come to think of it, you may have to do that with minicom, too. Personally, I change the udev rule that governs permissions for usb devices to give everyone access to the

If it were a permissions problem, it would have said so. Same if modemmanager controlled the port. Still, it doesn't hurt to try lsof and see if anything else is using the port. *lsof /dev/ttyUSB0* On Mon, Nov 16, 2020 at 5:36 PM Greg from Oz wrote: > Is the user running this in the dialout

The only thing I can think of to try is to reseat the logger. Unless, you actually have the serial version of the VantagePro and are using a serial-to-usb converter. They are notoriously flakey. If you have a spare one, try that. If none of that works, call Davis. On Mon, Nov 16, 2020 at 5:04 PM

Yes, I did hit enter many times. Since dmesg said that the usb had attached to ttyUSB0 then I assumed (maybe incorrectly) the rpi had connected. I’m at a loss because everything was working... Thanks. On Monday, November 16, 2020 at 7:59:54 PM UTC-5 tke...@gmail.com wrote: > OK, but did you hi

OK, but did you hit a few times before typing "TEST"? If so, you have a connectivity problem, not a WeeWX problem. But, you probably already knew that! -tk On Mon, Nov 16, 2020 at 4:57 PM bgra...@umw.edu wrote: > > I don’t remember the minicom string but it was the one posted to test > TEST.

I don’t remember the minicom string but it was the one posted to test TEST. When I opened minicom it just sat there no echo on TEST or VER. No reply. Several reboots no results. /dev/ttyUSB0 is there but does not respond. Dmesg Seems to have found it. I checked all plugs and connections. Remove

When you say you "tried listening to the console with minicom but got no data" what do you mean? In particular, did you set the baudrate? And, did you type a few types before trying to type TEST? -tk On Mon, Nov 16, 2020 at 2:55 PM bgra...@umw.edu wrote: > I have a VP2 console that I am conn

I have a VP2 console that I am connecting to an RPI OS (latest). Weewx is latest using setup.py. This RPI was running weewx (jessie) with no problems and using ttyUSB0 from weewx.conf. The vantage driver seems ok and I actually moved the old one over to be sure. I tried listening to the console
