First Day with WeeWX Some Good, but...

[scott pierce]

Successfully installed WeeWX on Rpi 5 and it's ingesting data from Davis Envoy USB Weather Link data logger.  

Also, I have been able to view reports...so that's nice.

I'm just beginning this journey so still a lot to learn and set up.

One quick question I can't find an answer to in the group or in notes...

when I run a status check this is the result...

I'm guessing I put the hardware name in wrong in setup...not sure.  Also don't know where to look to check.

Any suggestions are appreciated.

Thanks

If you set debug = 1 and restart weewx, we’ll get to see the hardware_type read from the envoy.

The line in the log will contain “Hardware type is “

Hi,

I was able to update the confi file and change the Debug to 1...which in itself is a huge win as it took me a while to figure out how to even access the file. (permissions have been a bear to learn).  I have read a lot in the last 24 hours!

That said, I still don't know how to access any additional log information.  When I run the status check, it comes back with basically the same info...

Also....where are the executables?  In the documentation it says:

This is a reference guide to the executable utilities that come with WeeWX:

• wee_config for changing the configuration file, and configuring new device drivers;
• wee_database for reconfiguring the database;
• wee_debug for producing debug reports for remote support;
• wee_device for configuring your hardware;
• wee_extension for installing and removing extensions;
• wee_import for importing historical data from external sources;
• wee_reports for running reports without running WeeWX itself;
• weewxd the main weewx program;
• wunderfixer for resending data missing on the Weather Underground site.

And then to find them....

Location of WeeWX components¶

ExecutablesBIN_ROOT/usr/share/weewx/

But when I look in that directory....

@spi-1:/usr/share/weewx $ ls
__pycache__  weecfg     weectl.py  weeimport  weeutil  weewx_data
schemas      weectllib  weedb      weeplot    weewx    weewxd.py
@spi-1:/usr/share/weewx $ 

None of them show up.  What am I missing?

Thanks

Maybe you missed that you refer to a 4.9 version of the docs, but you've installed a 5.1 version?

[scott pierce]

Yes, big rookie mistake.  Working through it now.  Thanks for pointing out!!

weewx.service: Main process exited, code=exited, status=4/NOPERMISSION generally means the user running the command is not in the required unix groups, which can be a little tricky to get right especially as a new linuc user.

Try ‘groups’ to see which groups your account is in, and ‘groups weewx’ to see which groups the weewx user is in. Your shell prompt is a bit unusual so I can’t see which account you are using in your log excerpts.

To an uneducated brain, this looks like a problem with the driver for the USB data logger from the Envoy.  I have NO idea what port the USB is going to on the Rpi so I just selected "the most common" option in the auto install process.  Could this be the issue?

Thanks

Sure it could, try “lsusb” to list the usb devices found. You might need to preface it with sudo.  Alternately unplug it, wait a couple seconds, plug it back in and run “sudo dmesg” to see kernel messages that usually have enough info to figure it out.

[30002.244987] usb 1-1: cp210x converter now attached to ttyUSB0

It returned a lot more information, but i figured the bottom lines are the one's we're interested in.

Sure looks like /dev/ttyUSB0 to me.

Lets eliminate group membership - give https://github.com/weewx/weewx/wiki/Understanding-permissions#more-details-about-which-groups-can-do-what a quick read and note the mention of group 'dialout' being the typical one needed for accessing USB devices.  Using the example above there, the command to add the weewx user to group dialout would be "sudo usermod -a -G dialout weewx" and you likely should restart weewx afterward. See if that cleans up your permission denied errors.

Hey,

Looks like that may have done it!  Not seeing those errors any longer:

Here is what I get now when I run weectl device:

scott@spi-1:~ $ weectl device

Using configuration file /etc/weewx/weewx.conf
Using driver weewx.drivers.vantage.
Using Vantage driver version 3.6.2 (weewx.drivers.vantage)

scott@spi-1:~ $ 

I'm going to keep drilling down, but I "think" this is a big step.

Thanks,  Vince, for your help!!!

[scott pierce]

Spoke too soon...

here is the latest error log.  I ran this same command right after restarting and there were no errors...I guess it needed time to run more processes:

It's really difficult to read partial truncated logs.

All I can suggest is (a) verify which groups 'weewx' is in and (b) perhaps try to run weewx interactively - just run "weewxd" and it should do the right thing thing.  You'd need to hit control-C once or twice to kill the process.    I don't have that hardware so I can't try to recreate it, but it still looks like a user group membership thing best guess.

[Graham Eddy]

weewx is reporting permission error. it seems to be using /dev/ttyUSB0 ➔ check perms on that file:

  $ ls -l /dev/ttyUSB0

it will probably show group ‘dialout’ has read/write on it, so make sure user ‘weewx’ is in that group

  e.g. $ sudo adduser weewx dialout

⊣GE⊢

[scott pierce]

Yep, WeeWx is already a member of that group. Here is the latest systems status I just ran.  Seems the unknown hardware issue is still there.  

Is there another log or status that I can run that will provide more/complete information?

Thanks

Scott

[Tom Keffer]

There have been a few other incidents of "Unknown hardware type 10". The solution seems to be to clear the logger. Try this procedure: 

 weectl device --dump
 weectl device --clear-memory

The "--dump" command will attempt to salvage any data on the logger. It will probably fail because of the "unknown hardware type" error, but it's worth a try.

Doesn't look like it worked.

Now you're back to a permissions error.

This is getting a tad frustrating!

[vince]

ok - lets go back to the beginning.  Is weewx getting data from your station and continuing to run other than these messages, or is it not ?   In other words do we have something breaking it from working, or is this just an annoyance in the logging/reporting stuff ?   If it's working - you 'could' just ignore it.  If it is 'not' working, we should keep trying to fix whatever is going on.

Again going back to one of your posts, you reported....

Here is what I have:

scott@spi-1:~ $ groups
scott adm dialout cdrom sudo audio video plugdev games users input render netdev lpadmin weewx gpio i2c spi

So if you wanted to put weewx into the same list of groups that a default pi user is in, you would do it via something like:

for group in adm dialout cdrom sudo audio video plugdev games users input render netdev lpadmin weewx gpio i2c spi

do

  sudo usermod -aG $group weewx

done

Then run 'groups weewx' to verify it's in all the default pi groups.  Then stop/restart weewx and test again.  If that doesn't work, personally I'd restart the pi, leaving it powered down for 30 seconds, for lack of a better idea I suppose.

Only other thing I can think of is whether you're using some whacked niche os or if it's the default Raspi OS (which is known to work).

The system install should have put a udev rule in place. This causes the kernel to create an alias to the device whenever it detects it plugging in (or at boot). Because if you have more than one serial device the envoy could get a different device name (ttyUSB1, ttyUSB3, etc.) every time it plugs in (like after a power bounce).

You can read the rules at /usr/lib/udev/rules.d/60-weewx.rules. The idVendor and idProduct values match what you saw in the lsdev command.

## udev rule

SUBSYSTEM=="tty",ATTRS{idVendor}=="10c4",ATTRS{idProduct}=="ea61",MODE="0664",GROUP="weewx",SYMLINK+="vantage"

## lsusb

Bus 001 Device 002: ID 10c4:ea61 Silicon Labs CP210x UART Bridge

If that worked you should see  /dev/ttyUSB0 with group weewx and /dev/vantage as a symlink to ttyUSB0.

#> ls -l /dev |grep USB
crw-rw-r-- 1 root weewx   188,   0 Feb  3 14:10 ttyUSB0
lrwxrwxrwx 1 root root           7 Jan 31 09:59 vantage -> ttyUSB0

So... your weewx.conf file should point to /dev/vantage

    # If the connection type is serial, a port must be specif

    #   Debian, Ubuntu, Redhat, Fedora, and SuSE:
    #     /dev/ttyUSB0 is a common USB port name
    #     /dev/ttyS0   is a common serial port name
    #   BSD:
    #     /dev/cuaU0   is a common serial port name

    port = /dev/vantage

Worth a try.  I do like the "ls -l /dev | grep USB" command to better see what's what in /dev given that it looked like he has a USB keyboard and mouse plugged in.
