At first glance the weewx messages in the syslog look fine.
You seem to have a webserver issue.
If I understand your question properly, you fail to get the data displayed on the screen when entering the URL
http://your-ip-of-the-Rpi/weewxcorrect ? (or did you enter:
http://your-ip:8001/weewx ? that won't work usually)
Your webserver - if you have installed one at all, what you have to, otherwise you cannot receive anything in your browser - should provide at least some response when you enter
http://your-ip-of-the-RPi/weewxwhat's the response ?
Your web server should listen at port 80 (default http port) and will forward your request to /var/www/weewx/html
Then, if you have a look into the directory /var/www/html/weewx on Raspbian, e.g. with the file manager, you should see a lot of files, graphics files, ending in .png and starting day.....png, week....png, month ....png and year....png there which have been created by weewx (by the Cheetah-generator) as your syslog entry says - 15 images
Do you see them there ? - they should have a similar timestamp as the "archived data" - added record .... to weewx.sdb
Also the port number is only for the communication between your console and weewx - it has nothing to do with you reading the data into the web interface (weewx term: skin)
Your interceptor stanza in weewx.conf should look like
[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
# ecowitt-client - any hardware that uses the ecowitt protocol
# wu-client - any hardware that uses the weather underground protocol
device_type = ecowitt-client
port=8001
----------------
because you say you have entered port # 8001 in the WSView app - and the IP of your RPi
and your station stanza should look like (the sequence in weewx.conf is reverse - 1st station, 2nd Interceptor)
---------------
[Station]
# Description of the station location
location = "your location"
# Latitude in decimal degrees. Negative for southern hemisphere
latitude = xx.xxxx
# Longitude in decimal degrees. Negative for western hemisphere.
longitude = x.xxxx
# Altitude of the station, with unit it is in. This is downloaded from
# from the station if the hardware supports it.
altitude = xxx 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 = Interceptor
