# Rapsberry Pi MQTT monitor
Python 2 script to check cpu load, cpu temperature, free space, voltage and system clock speed
Python 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)
I wrote this so I can monitor my raspberries at home with [home assistant](https://www.home-assistant.io/). The script was written and tested on Python 2 but it should work fine on Python 3.
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.

Once you installed the script on your raspberry you need to create some sensors in home assistant.
This is the sensors configuration assuming your sensors are separated in sensors.yaml file.
```yaml
- platform: mqtt
state_topic: "masoko/rpi4/cpuload"
name: rpi 4 cpu load

state_topic: "masoko/rpi4/cputemp"

unit_of_measurement: "°C"
