rpi-fan

Description

This script checks current RaspberryPi temperature and in case it's higher than limit set by user it will enable fan and display notification on OSMC display.

Script checks current device temperature every 2 seconds. In case temperature will be too high, fan will be enabled for 120 seconds and then temperature will be rechecked.

Installation

Download file fan.py and place it wherever you like.
Execute command sudo crontab -e
Add new cron entry, example: @reboot /usr/bin/python /home/osmc/scripts/fan.py -l INFO -t 45.0. Script will start with RaspberryPi

Available arguments:
