On a RPi you have to add the following line to your weewx.conf
device_type = ecowitt-client
port = 8000
iface = eth0 #if you are using the Ethernet port
#or
iface = wlan0 #if you are using the WiFi of the RPi
# only one of them 😉
you also have to make sure that no other application on the RPi uses
port 8000
you can try 8001 or 8777 (on both ends - weewx.conf and WSView
app/console) - maybe port 8000 is used ....

When you just ran the interceptor driver directly there should have
been output to the console as well as log output in the WeeWX log, not
sure what log file it will be in as I am not a Centos user. Can you
please post the log output exactly as it appears in the log.

According to WireShark there is this communication about once each
minute, but I have only one entry in the terminal.

You have changed many things in your setup and even though you
appear to have reverted to your original working configuration
I would be starting from scratch as per the interceptor drive
readme.I would be running the driver directly and then making
sure you use the —debug command line option. Post the console
output here. Let’s see where that gets us.

I have been using weewx on a Raspberry Pi for about two
years now. After my old Fine Offset died soon after I
moved from pywws I bought a Eurochron WS2900 which I got
running using the interceptor driver, and that worked fine
until the weather station stopped giving temperature
readings this winter. I was able to fix that last week
(bad connector on the cable from the temperature sensor to
the circuit board in the sensor array) but when I
reconnected it to weewx I started to experience various
odd things. The unit shows correct data on its display and
sends data to weewx, and the webpages rendered by weewx
are correct (e.g. temperature ranging between 16°C and
28°C the other day) but the temperatures sent to Windy
(and others) by weewx varies from -2°C to 21°C for the
same day. Thinking that there might be some API change or
something during the half year my station was offline, and
that I for some time have had thoughts of moving it to a
virtual server on my ESXi station anyway, I set up a
Centos 8 machine and installed weewx on it. Simulator
works fine, but using the same interceptor settings as on
my Raspberry Pi I don't get any data (IP updated in the
weather station settings).
Using
PYTHONPATH=/usr/share/weewx python3 -m user.interceptor
--debug --mode=listen --port=8000 --device=ecowitt-client
I was able to once capture this after listening maybe one
hour:
raw data:
raw packet: {'dateTime': 1627416663, 'usUnits': 1}
mapped packet: {'dateTime': 1627416663, 'usUnits': 1}
Yay! A timestamp!
Trying to connect to port 8000 from another computer in
the network shows that the port is open.
Thinking there is some problem with the weather station I
have reseted it, but no change. The device is by itself
directly uploading to Weather Underground and some other
sites, and that works.
Frustrated I one again change the local IP the weather
station should send data to to the Raspberry Pi, but now I
don't get any data there at all.
This is the interceptor settings of weewx.conf:
…
station_type = Interceptor
…
##############################################################################
[Interceptor]
# This section is for the network traffic interceptor
driver.
# The driver to use:
driver = user.interceptor
# Specify the hardware device to capture. Options
include:
# acurite-bridge - acurite internet bridge,
smarthub, or access
# observer - fine offset WH2600/HP1000/HP1003,
ambient WS2902
# lw30x - oregon scientific LW301/LW302
# lacrosse-bridge - lacrosse GW1000U/C84612 internet
bridge
# wu-client - any hardware that uses the weather
underground protocol
# device_type = observer
device_type = ecowitt-client
port = 8000
##############################################################################
I'm not sure what more is relevant logs to post.
I see no dropped packages originating from the weather
station in the firewall log.
Does anyone have any idea how I should proceed or what I
should try?
