Home Assistant Integration (outdated)

If you are using discovery_messages, then this step is not required as a new MQTT device will be automatically created in Home Assistant and all you need to do is add it to a dashboard.

Once you installed the script on your raspberry you need to create some sensors in home assistant.

This is the sensors configuration if group_messages = True assuming your sensors are separated in sensors.yaml file.

  - platform: mqtt
    name: 'rpi4 cpu load'
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[0] }}'
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[1] }}'
    name: rpi4 cpu temp
    unit_of_measurement: "°C"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[2] }}'
    name: rpi4 diskusage
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[3] }}'
    name: rpi4 voltage
    unit_of_measurement: "V"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[4] }}'
    name: rpi4 sys clock speed
    unit_of_measurement: "MHz"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[5] }}'
    name: rpi4 swap
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[6] }}'
    name: rpi4 memory
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[7] }}'
    name: rpi4 uptime
    unit_of_measurement: "days"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[8] }}'
    name: rpi4 wifi signal
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: 'masoko/rpi4'
    value_template: '{{ value.split(",")[9] }}'
    name: rpi4 wifi signal
    unit_of_measurement: "dBm"

This is the sensors configuration if group_messages = False assuming your sensors are separated in sensors.yaml file.

  - platform: mqtt
    state_topic: "masoko/rpi4/cpuload"
    name: rpi4 cpu load
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: "masoko/rpi4/cputemp"
    name: rpi4 cpu temp
    unit_of_measurement: "°C"

  - platform: mqtt
    state_topic: "masoko/rpi4/diskusage"
    name: rpi4 diskusage
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: "masoko/rpi4/voltage"
    name: rpi4 voltage
    unit_of_measurement: "V"

  - platform: mqtt
    state_topic: "masoko/rpi4/sys_clock_speed"
    name: rpi4 sys clock speed
    unit_of_measurement: "hz"

  - platform: mqtt
    state_topic: "masoko/rpi4/swap"
    name: rpi4 swap
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: "masoko/rpi4/memory"
    name: rpi4 memory
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: "masoko/rpi4/uptime_days"
    name: rpi4 uptime
    unit_of_measurement: "days"

  - platform: mqtt
    state_topic: "masoko/rpi4/wifi_signal"
    name: rpi4 wifi signal
    unit_of_measurement: "%"

  - platform: mqtt
    state_topic: "masoko/rpi4/wifi_signal_dbm"
    name: rpi4 wifi signal
    unit_of_measurement: "dBm"

Add this to your customize.yaml file to change the icons of the sensors.

sensor.rpi4_voltage:
  friendly_name: rpi 4 voltage
  icon: mdi:flash
sensor.rpi4_cpu_load:
  friendly_name: rpi4 cpu load
  icon: mdi:chip
sensor.rpi4_diskusage:
  friendly_name: rpi4 diskusage
  icon: mdi:harddisk
sensor.rpi4_sys_clock_speed:
  icon: mdi:clock
sensor.rpi4_cpu_temp:
  friendly_name: rpi4 cpu temperature
sensor.rpi4_swap:
  icon: mdi:folder-swap
sensor.rpi4_memory:
  icon: mdi:memory

After that you need to create entities list via the home assistant GUI. You can use this code or compose it via the GUI.

type: entities
title: Rapsberry Pi MQTT monitor
entities:
  - entity: sensor.rpi4_cpu_load
  - entity: sensor.rpi4_cpu_temp
  - entity: sensor.rpi4_diskusage
  - entity: sensor.rpi4_voltage
  - entity: sensor.rpi4_sys_clock_speed
  - entity: sensor.rpi4_swap
  - entity: sensor.rpi4_memory
  - entity: sensor.rpi4_uptime
  - entity: sensor.rpi4_wifi_signal
  - entity: sensor.rpi4_wifi_signal_dbm
