Rapsberry Pi MQTT monitor
Python 2 script to check cpu load, cpu temperature, free space, voltage and system clock speed on a Raspberry Pi computer and publish the data to a MQTT server.
I wrote this so I can monitor my raspberries at home with home assistant. The script is writen for python 2 as when I wrote it one of the used python modules was not available for python 3. (if the modules are available for python 3 now the script shuold have no problems running on python 3 - plan to check that in the near feature) The script if very light, it takes 4 seconds as there are 4 one second sleeps in the code - due to mqtt have problems if I shoot the messages with no delay.
Installation:
If you don't have pip installed:
$ sudo apt install python-pip
Then install this module needed for the script:
$ pip install paho-mqtt
Rename config.py.example to config.py and populate the needed variables
Test the script.
$ /usr/bin/python /home/pi/scripts/rpi-cpu2mqtt.py
Create a cron entry like this (you might need to update the path on the cron entry below, depending on where you put the script):
*/2 * * * * /usr/bin/python /home/pi/scripts/rpi-cpu2mqtt.py
