A python code to create an IoT device from a Raspberry
1 - Install needed dependencies:
sudo apt-get update
sudo apt-get install screen git-core python-pip
pip install influxdb Adafruit-bitfield Adafruit-GPIO smbus
2 - Change the i2c baudrate of your Raspberry for the CCS811 sensor, otherwise it won't work:
sudo nano /boot/config.txt
Add this line: dtparam=i2c_baudrate=10000
3 - Once everything is done, clone this repo:
git clone https://github.com/algernhon/raspiot.git
1 - In order to run this app smoothly, download this 3 files (opt):
wget https://raw.githubusercontent.com/algernhon/raspiot-launcher/master/start.sh
wget https://raw.githubusercontent.com/algernhon/raspiot-launcher/master/update.sh
wget https://raw.githubusercontent.com/algernhon/raspiot-launcher/master/config.py
Start.sh: This script starts the application in a screen window.
Update.sh: This script stops, downloads the latest version and relaunches the Raspiot app.
Config.py: This is the config file you need to modify if you use those 3 files. This one will be copied into your Raspiot folder every time you update the app.
Give them the permission to be executed:
chmod +x start.sh update.sh
2 - Add the startup script to crontab (opt):
crontab -e
Add this line (change the path if different): @reboot /home/pi/start.sh
3 - Now config your Raspiot (InfluxDB info & sensors config):
nano config.py
Launch the app for the first time with the update script (your config file is going to be copied to the raspiot app):
./update.sh
If you have already launched this app at least once, execute the start script:
./start.sh
