Set up pagekite and login on your Pi. Ideally this would go in autorunonce.sh but I haven't figured out how to run pagekite.py --signup in a noninteractive way.
curl -s https://pagekite.net/pk/ |sudo bash
pagekite.py --signup
In autorunonce.sh, install pagekite and register this device. Replace things in angle brackets with your info.
# connect to wifi
pirateship defaults
pirateship adapter <wifi network name> WPA <wifi password>
ifdown wlan0
ifup wlan0
# install pagekite
pagekite.py --add 22 ssh:<user>.pagekite.me
In autorun.sh. Note the ampersand after the pagekite command. This keeps pagekite from stopping execution of the following watch command.
#!/bin/bash
pagekite.py &
watch -n15 "./opk-cli--yoctopuce-temperature/pull | ./opk-cli--phant/push --public_key AJOJ0mxKQDtJ2qdMV7rM --private_key rzvzj651MXc5Vqn6Kgl6 --url data.sparkfun.com --field_name temp"
Per the Pagekite docs, on your own machine that you will SSH from, add this to your ~/.ssh/config file.
Host *.pagekite.me
CheckHostIP no
ProxyCommand /bin/nc -X connect -x %h:443 %h %p`
If you are on a Mac, change /bin/nc to /usr/bin/nc.
Plug everything in and then ssh in by doing...
ssh pi@<user>.pagekite.me
