Install Raspbian on your Pi. In the setup process go to Advanced and enable SSH. Also, set it to boot to the command line rather than the desktop – you should be able to run this headless.
Do some basic maintenance
sudo apt-get update sudo apt-get upgrade sudo rpi-update sudo reboot
sudo apt-get install python-configobj
sudo apt-get install python-cheetah sudo apt-get install python-imaging sudo apt-get install python-usb
Now install WeeWX
Visit http://weewx.com/downloads to find the link to the latest .deb file. In this case it is weewx_3.3.1-1_all.deb.
sudo dpkg -i weewx_3.3.1-1_all.deb
The installer will ask you for a location, lat/long (decimal degrees) of your location, altitude, station type and hardware model.
For the W8681 it is a “FineOffsetUSB” type, and the model # is “W-8681”
sudo tail -f /var/log/syslog
will give you an idea of if it is working or not.
If dpkg complains of missing dependencies then simply perform sudo apt-get update followed by sudo apt-get -f install.
You might notice in the syslog that you get a USB error – this occurs if you have not yet plugged in the weather station receiver.
sudo /etc/init.d/weewx stop
Plug in the receiver if you haven’t already.
Then, edit /etc/weewx/weewx.conf. I used nano. You will need to be root.
Adjust settings such as piping it to wunderground, or to aprs.fi/CWOP if you would like.
Save the file, and then start weewx again:
sudo /etc/init.d/weewx start
