Flash raspbian to a SD card and boot the Raspberry. Find the IP address using nmap -sP [ip-adress]/[bitmask], e.g. nmap -sP 192.168.0.0/24.
Open a SSH client and connect to the determined IP. The default username and password are pi and raspberry.
Type sudo raspi-config to expand the filesystem, change the password and set the local time zone.
Enable IPv6: Add ipv6 on a line by itself at the end of /etc/modules.
Install at. Needed to remain tunslip6 started because UDEV rules kill the spawning process.
sudo apt-get install at
Credits to Marc Hüppin for the initial version.
openssl and libssl-dev are required for SSL support in python and is required by pip.
sudo apt-get install sqlite3 libsqlite3-dev openssl libssl-dev
install the sqlite3 packages

- udev rules:
sudo ln -s /home/pi/smart-heating-local/rules.d/90-local.rules /etc/udev/rules.d/ - tunslip executable:
sudo ln -s /home/pi/smart-heating-local/bin/tunslip6 /bin/
Add this line to /etc/rc.local to make sure the udev rule is also executed on startup
udevadm trigger --verbose --action=add --subsystem-match=usb --attr-match=idVendor=0403 --attr-match=idProduct=6001
Reboot: sudo reboot
Attach the sky tmote usb dongle to the raspberry. The tun0 interface should be shown by ifconfig.
In case of problems run sudo ~/smart-heating-local/bin/start_tunslip.sh manually.
Determine the ipv6 address of the web service: less /var/log/tunslip6:
Server IPv6 addresses:
fdfd::212:7400:115e:a9e5
fe80::212:7400:115e:a9e5
Retrieve the registered routes on the border router: wget http://[fdfd::212:7400:115e:a9e5]:

Test route to the thermostat by requesting the current temperature via coap-client (libcoap):
~/smart-heating-local/bin/coap-client -m get coap://[fdfd::221:2eff:ff00:22d3]/sensors/temperature
v:1 t:0 tkl:0 c:1 id:11708

Congratulations, your raspberry is connected to a thermostat!
Install pip: https://pip.pypa.io/en/latest/installing.html
Install the project requirements:
cd ~/smart-heating-local/
pip install -r requirements.txt
Setup crontab to run the log and upload scripts periodically.
crontab -e
# Insert these lines at the end of the file:
*/15 * * * * /usr/local/bin/python3.4 /home/pi/smart-heating-local/thermostat_sync.py
*/5 * * * * /usr/local/bin/python3.4 /home/pi/smart-heating-local/server_sync.py
These commands ensure that the temperature is polled from the registered thermostats each 15 minutes and checked for uploading to the server each 5 minutes.
The scripts log interesting events to ~/smart-heating-local/logs/smart-heating.log.
