# 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.
|
|
|
|
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):
|
|
|
