• Run the Raspberry Pi Configuration Tool:

sudo raspi-config 

• Go to this points:
• "Expand Filesystem"
• "Change User Password"
• "Internationalisation Options" ==> "Change Timezone"
• Reboot:

sudo reboot

• Install webserver like lighttpd

sudo apt-get update
sudo apt-get install lighttpd

• Download icons:
• Download the openHAB "Runtime core" from http://www.openhab.org/getting-started/downloads.html
• Unpack the file distribution-1.8.2-runtime.zip
• Copy the PNG files from openHAB Runtime directory webapps/images/ to directory /var/www/html/icons/
• Install Git:

sudo apt-get install git  

• Copy the files from the repository to the home directory:

git clone https://github.com/anthal/snom_smarthome

• Install PIP (Python package manager):

sudo apt-get install python-pip 

• Install miscellaneous Python packages:

sudo apt-get install python-dev  
sudo pip install simplejson
sudo pip install phue
sudo pip install psutil
sudo pip install feedparser
sudo pip install pyowm

Configuration

On a Raspberry Pi:

• Go in directory /home/pi/snom_smarthome/CeBit2016
• Set the execute bits:

chmod +x *.py
chmod +x *.sh

• Adapt in conf.py:
• server_ip to the IP address of your Raspberry Pi:

server_ip = '172.20.4.117'

• homematic_ip to the IP address of your Homematic CCU:

homematic_ip = '172.20.4.110'

• hue_ip to the IP address of your Philips Hue bridge:

config['hue_ip'] = '172.20.4.113'

• cam1_url to the URL of your IP Webcam for picture:

config['cam1_url'] = 'http://admin:admin@172.20.4.111/tmpfs/auto.jpg'
config['cam2_url'] = 'http://admin:admin@172.20.4.112/tmpfs/auto.jpg'

• my_owm_api_key get key from http://openweathermap.org/appid:

config['my_owm_api_key'] = '11111111111111111111111111111'

• city the city for weather values:

config['city'] = 'Berlin,ger'

• Change the addresses to your Homematic devices:

########################### Homematic ###########################
# Sockets:
config['addr_wz_socket1'] = 'LEQ4272335'
config['addr_az_socket1'] = 'LEQ4272349'
config['addr_sz_socket1'] = 'LEQ4272278'
# Heizungssteller (Thermostat):
config['addr_wz_heating1'] = 'MEQ4797228'
config['addr_sz_heating1'] = 'MEQ4797228'
# Temp./ Feuchte Sensor (Temp./ Humidity Sensor):
config['addr_az_sensor1'] = 'MEQ4202864'
# Fensterkontakt (Window Sensor):
config['addr_wz_window1'] = 'MEQ4484674'

• Get new data from RSS feed:

python get_rss.py

• Start main script:

python main

• Press the configuration key on the Philips Hue Bridge
• Crontab (crontab -e):
• You can use the script start_main.sh for start per crontab and the script get_rss.py to update the RSS feed per crontab:

* * * * * /home/pi/snom_smarthome/CeBit2016/start_main.sh
0 * * * * /home/pi/snom_smarthome/CeBit2016/get_rss.py

On snom phone:

• WEB GUI: "Function Keys" -key like SNOM/CLOUD / Type: "Action URL": "[http://IP_addr_of_Rasperry_Pi]:8083"
