temperatures

Requisites

• Raspberry Pi or similar
• w1-gpio & w1-therm
• DS18B20 sensor(s)
• Python3

Client installation

Add modules

sudo echo w1-gpio >> /etc/modules
sudo echo w1-therm >> /etc/modules

Install requirements

Python3-dev

You need the python3-dev package to compile PyCrypto

sudo apt-get install python3-dev

PyCrypto

Get the latest version from https://www.dlitz.net/software/pycrypto/

Note: If you're building on a Raspberry Pi or any other low powered device it may seem like it hangs on "Skipping implicit fixer: set_literal". Give it some time, my Pi used about 5 minutes on this step.

wget http://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz
tar xvf pycrypto-2.6.1.tar.gz
cd pycrypto-2.6.1/

sudo python3 setup.py build
sudo python3 setup.py install

Now you can clean up and remove the pycrypto-2.6.1-folder

Set up crontab

I have register_temperatures.py fire every minute and upload_temperatures.py fire every 5 minutes.
