Hi,

I used to use WS2300 with wview (RIP).

Now i try to configure weewx with ws2300 on Raspberry and it does not work ...

i installed it with apt-get.

dmesg :

[    1.623394] usb 1-1.4: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 4.00

#modprobe ftdi_sio
#ls /dev/ttyUSB*
/dev/ttyUSB0

weewx.conf :

...

[Station]

    # Description of the station location
    location = ""

    # Latitude and longitude in decimal degrees
    latitude = 50.000
    longitude = 1.000

    # Altitude of the station, with unit it is in. This is downloaded from
    # from the station if the hardware supports it.
    altitude = 100, meter

    # Set to type of station hardware. There must be a corresponding stanza
    # in this file with a 'driver' parameter indicating the driver to be used.
    station_type = WS23xx

    # If you have a website, you may specify an URL
    #station_url = http://www.example.com

    # The start of the rain year (1=January; 10=October, etc.). This is
    # downloaded from the station if the hardware supports it.
    rain_year_start = 1

    # Start of week (0=Monday, 6=Sunday)
    week_start = 0

    port = /dev/ttyUSB0

    # The station model, e.g., 'LaCrosse WS2317' or 'TFA Primus'
    model = LaCrosse WS-2300

    # The driver to use:
    driver = weewx.drivers.ws23xx

...

and when i ask wee_device --current

Does anyone has an idéa ?

did you have root permissions when you invoked wee_device?

you can try connecting directly with the driver:

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

to see all the options:

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

typical problems with this weather station include:

* permissions - be sure to use sudo when connecting to the port, or create a udev rule that grants permissions to non-root users

* poor signal strength (only when using wireless mode)

* buggy libusb/serial in the operating system (typically in older rpi systems)

To be sur i did it again :

#sudo PYTHONPATH=/usr/share/weewx python /usr/share/weewx/weewx/drivers/ws23xx.py --readings


Traceback (most recent call last):


  File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 2120, in <module>
    data = s.get_raw_data(SENSOR_IDS)

    raw_data = read_measurements(self.ws, measures)
  File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 2037, in read_measurements
    nybbles = ws2300.read_batch(batches)
  File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 1201, in read_batch
    self.reset_06()
  File "/usr/share/weewx/weewx/drivers/ws23xx.py", line 1070, in reset_06
    raise self.Ws2300Exception(msg)
__main__.Ws2300Exception: Reset failed, 100 retries, no response

The station is wired connected.

Solution : buggy libusb/serial in the operating system (typically in older rpi systems) ???

this is the place to ask. maybe there is someone else running a ws23xx on an rpi?

i am running a ws23xx but it is on an x86_64 system (with an ancient version on debian), i'm afraid i am not much help

Linux saga 3.2.0-4-amd64 #1 SMP Debian 3.2.81-2 x86_64 GNU/Linux

can you try running weewx on an x86/x86_64 system?

you might have to hunt around the rpi forums for information about serial and usb-serial settings. i seem to recall the rpi default configuration of the modem/tty causing problems for some serial communications.

you could also look at some of the resources listed in the comments in the ws23xx.py driver file. the driver is based mostly on Russell Stuart's implementation, with some bug fixes. if you can get his original implementation to work, that might provide a clue about what is different about the serial setup on arm/rpi. or perhaps try the Kenneth Lavrsen Open2300 implementation.

i'm happy to incorporate whatever you find so that the weewx ws23xx driver will work reliably on any platform, but i'm afraid i do not have time right now to set up an rpi or other arm platform to do the exploratory work.

It Works !!!

The ws 2350 was the problem.

After clean inside it ... all is ok.

all ... except ... rsync over ssh ... ;)

ssh is ok (can connect without password) ...

rsync log : imagegenerator: Generated 12 images for RSYNC in 0.36 seconds

but nothing on the server ...

on command line, it works weel :

'rsync' '--archive' '--stats' '-e ssh' '/var/www/html/weewx/' 'user@server:/home/meteo/www/'

Where can i put verbose mode for rsync in weewx to understand what s going wrong way ?
