server_fan

Script manages attached fan for cooling the system on the basis of the system temperature provided by the SoC [1]. At the same time the script acts as an MQTT [2] coordinator utilizing local MQTT broker mosquitto for data exchange within IoT [3]. Script communicates with cloud services like ThingSpeak and Blynk.

• For the sake of generating the documentation with the system Sphinx, the repository might be handled as a package.
• The script is aimed for Pi microcomputers running as headless servers, e.g., Raspberry Pi, Orange Pi, Nano Pi, etc.
• The documentation configuration for the script is located in the folder docs/source. The documentation can be generated from the folder docs in HTML [4] format by the command make html and in PDF [5] format by the command make latexpdf.
• The generated documentation of the script is published on the dedicated Github page server_fan.
• The script can run under Python2 as well as Python3. However, it is defaulted to Python3 by the shebang.
• It is recommended to run the script as a service of the operating system.
• All relevant parameters for the script are located in the configuration INI file. It contains sensitive data as well, like passwords and access tokens to servers and clouds. So that the repository contains just the sample INI file with placeholders instead of real such as sensitive data. The production INI file should be present only and only in some trusted locality with root access, e.g., in the folder /usr/local/etc in order not to be exposed to regular users.
