Bonjour,
I have recently buy a Vantage station with a meteo-pi (https://wifilogger.net/meteopi.html) in a rasperry pi3. Weewx worked well with Simulator but since I connected the station and chose the Vantage driver I have nothing. Weewx don't start with this message :

I didn’t find anything to solve this problem, but I may have looked for it wrong.
As you can see my English is minimum  and don’t be offended by my problems of understanding.

Merci.

you need to post your syslog from the time *before weewx first starts* until after its says EXITING.
pay particular attention to anything said about the serial port

As soon as I manage to restore the capricious wifi of the Raspberry, I send you this.

sorry, i should also have said: set debug to 1 (near top of weewx.conf).
that will tell us more about the dialogue between vantage and weewx

the syslog says it is successfully opening the serial device file, but not getting a sensible response (probably no response at all), in other words a communication problem between port and vantage pro

this forum contains many cases where people have had to check their serial port communicating with vantage pro.
there are many possible causes so i suggest searching the forum for the steps required

I am not familiar with the Meteo-pi, but are you sure that it connects through a classic serial port (e.g., /dev/ttyS0), rather than a USB port (e.g., /dev/ttyUSB0)?  Or, perhaps something else?

You should ask the vendor.

Thanks to all
$ sudo ls /dev/ttyUS*
ls: impossible d'accéder à '/dev/ttyUS*': Aucun fichier ou dossier de ce type

I also tried with/dev/AMA0 but I had errors saying it wasn’t that.

At the seller it is said : «Meteo-Pi appears to software running on the Pi computer as a simple serial device (ie connecting via a COM port) and so virtually any Pi-compatible software should be able to receive data from the console and in the same formats as any other Davis logger. NB This will typically place the Meteo-Pi on port /dev/ttyS0 (though it’s conceivable that different Pi or Raspbian versions might use eg ttyS1 or something else).»

I would try /dev/ttyUSB0.

But, really, you should contact the vendor.

It appears that meteo-pi requires some special configuration in /boot ....

See step 3 on https://www.weatherstations.co.uk/setting-up-meteo-pi-part-2.htm 

Meteo-Pi is designed so that data is presented to the Pi on a serial port. But a slight change to the default serial configuration of the Pi is required which needs a couple of edits to text files in the Pi’s boot directory. These two files are both accessible from Windows so the necessary changes can be made with a simple text editor either eg on a Windows PC before the card is placed in the Pi or, if more convenient, on the Pi itself (in which case a reboot is needed after both edits are made). The two changes required are:

edit /boot/config.txt and add on the end
“enable_uart=1”

edit /boot/cmdline.txt and remove
“console=serial0,115200”

I'll add my $0.02 worth... for the serial ports and RTC I got for this, there were a couple of boot changes required.
In /boot/config.txt, this:
enable_uart=1

# uncomment to enable RTC module
dtoverlay=i2c-rtc,ds1307

And my RPi 3 (or 3+), this:
# Additional overlays and parameters are documented /boot/overlays/README
dtoverlay=disable-wifi
dtoverlay=disable-bt

The bluetooth module uses the fancier of the uarts, so disabling that enabled the regular serial port
to use the better uart.

In any case, see the Knowledge Base articles here: https://www.abelectronics.co.uk/p/51/serial-pi-plus
and see if any of those details make sense to you.  The meteo-pi doesn't seem all that different than this
serial port + the RTC clock they sell.

Try running this very simple program. Substitute whatever port you are using for '/dev/ttyS0'.

import serial
import time

s = serial.Serial('/dev/ttyS0', 19200, timeout=3)

s.write(b'\n')
time.sleep(0.5)
s.write(b'TEST\n')
time.sleep(0.5)
buf = s.read(10)
print(buf)

This little program will do the standard Davis test for connectivity by asking the console to echo the word "TEST". It should print out something like:

response: b'\n\r\n\rTEST\n\r'

If not, then you are either on the wrong port, or the logger is not acting like a true clone.

Thanks. With  /dev/ttyS0 I get:
pi@raspledeuix:~ $ python /home/pi/samsung/serie.py

pi@raspledeuix:~ $ 

nothing

Same answer with /dev/AMA0


$ dmesg | grep serial

[    0.931796] 3f201000.serial: ttyAMA0 at MMIO 0x3f201000 (irq = 81, base_baud = 0) is a PL011 rev2

But I find:

1, Nothing? Under Python 3, it should have at least printed a null string. Something like

b''

2. You are on the right track for figuring out which serial port your Meteo-pi is using. However, by using 'grep serial' you are excluding usb converter messages. Instead, try

dmesg | grep 'tty'

3. Assuming you have the right port, your Meteo-pi is not acting like a Davis clone.

No more an empty row.Sometime "[]"

The seller answered and sent me a manual for … Cumulus. I will try
anyway tomorrow.

I think I found the responsible: the 6-conductor cable. With the
4-conductor cable, it seems to work. Wait and see…
