engine: Unable to load driver: (5, 'Input/output error')

[Kevin Bosworth]

I had this running on an older Lubuntu laptop that died. Seems I had no problems then. So here is what I have.

Lubuntu 12.04


sudo tail -f /var/log/syslog

Not sure what else to do. Tried copying my old backup config files with the same results. I did add myself to to the dailout group.

Thanks, Kevin

Can anyone help me out here??!!

Things to try:

Does /dev/ttyS0 actually exist?

It looks like you are running weewxd as a daemon, which is usually run as root, so adding yourself to the dialout group will not make any difference. In any case, try running from the command line, and try running as root (by using a 'sudo' prefix). This may give you clues. 

Try running the driver directly. It can give you more clues about what's happening. The command

PYTHONPATH=/usr/share/weewx python /usr/share/weewx/weewx/drivers/ws23xx.py --help

will show you the options available.

How do I run it normally and not as a daemon?

I have read that big freaking manual 20 times already. Wonder how I ever got the dang thing working in the first place. For some reason it seems like I had heavyweather running also.... But I don't remember.

kevin,

those are the functions that the ws23xx driver uses to communicate over the serial port.  they are more direct than the pyserial library that many other drivers use.

what kind of computer are you using now?

is the weather station connected to a serial port, or to a usb port using a serial-to-usb adapter?

It is a old dell laptop. Latitude D600. Serial port and ttyS0 exists. Do I need to install a different library?

no need to install any libraries.

now try running the driver directly.  if you installed from deb package, it looks like this:

cd /usr/share/weewx
sudo PYTHONPATH=. python weewx/drivers/ws23xx.py --port /dev/ttyS0 --readings

if you installed using setup.py it looks like this:

cd /home/weewx/bin
sudo PYTHONPATH=. python weewx/drivers/ws23xx.py --port /dev/ttyS0 --readings

you should see readings from the station sensors.

ok... So my serial port got changed in BIOS. So I tried this.
setserial -g /dev/ttyS[0123456789]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
/dev/ttyS2: No such device
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
/dev/ttyS4, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS5, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS6, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS7, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS8, UART: unknown, Port: 0x0000, IRQ: 0
/dev/ttyS9, UART: unknown, Port: 0x0000, IRQ: 0

Now I know it is on COM1 or TTYS0. I then ran the command you gave me with the following.

sudo PYTHONPATH=. python weewx/drivers/ws23xx.py --port /dev/ttyS0 --readings

{'rt': 556.0, 'wc': -2.4, 'cn': 15, 'oh': 85.0, 'it': 22.8, 'ih': 42.0, 'pa': 837.4, 'dp': -4.6, 'ot': -2.4, 'rh': 0.0, 'wind': (0.0, 225.0, 0, 0)}

So I guess it is working. But nothing in the WWW Directory. When I use "sudo /etc/init.d/weewx start" I get ,
* Starting weewx weather system weewx                                   [ OK ]

So now what I guess is my next question. :)

Thanks, Kevin

what is the archive interval for the station?  factory default for ws23xx is 30 minutes, so you probably just need to wait.  or change the interval.

[kevin...@gmail.com]

So I said to help with it. I reinstalled lubuntu. And did the weewx install. Everything went perfect like the old laptop. The only thing I can not figure out is how to get the webpage to update every 5 min like before. I set the archive interval to 300 sec, but is only updating every hour. Ideas?

Thanks, Kevin

Can you be more specific?  How frequently are the archive records being saved?  Ids the issue with the creation of the html pages, the .png image files, the ftp of the data to a remote site, or in the browser viewing the html/png files??

what exactly hap[pens every hour, and/or every 5 minutes?

A copy of the log would be useful to understand what is happening!!

It has previously been reported that nginx has some high default media cache times - but you do not say what/how the data is being served or created.
