HASS host sensors

Simple MQTT interface for hass.io (HomeAssistant) host sensors. It runs as systemd service. Every RestartSec interval service will publish JSON to topic {host_name}/sensors_data. Fields are presented below:

{
    'cpu_temp': {float, one decimal place, celsius},
    'cpu_freq': {float, one decimal place, MHz},
    'cpu_load_percent': {float, one decimal place, percent},
    'ram_load_percent': {float, one decimal place, percent},
    'swap_usage': {float, one decimal place, percent},
    'root_fs_disk_usage': {float, one decimal place, percent}
}

Installation

Required python version >= 3.6

Step 1. Download source

$ git clone https://github.com/cybernextgen/hass_host_sensors.git
$ cd hass_host_sensors
$ pip install -r hass_host_sensors/requirements.txt

Step 2. Edit configuration constants inside task.py module:

SETTINGS = {
    'mqtt_brocker_host': 'localhost',
    'mqtt_brocker_port': 1883,
    'mqtt_brocker_user': '',
    'mqtt_brocker_password': ''
}

Inside hass_host_sensor.service edit next lines:

ExecStart = {path to python3} {path to task.py}
User = {user} # run service as specific user and group
Group = {user group}
...
RestartSec = 60 # interval between sensors data reads

Step 3. Enable and run service

$ cp hass_host_sensors.service /etc/systemd/system/hass_host_sensors.service
$ systemctl enable hass_host_sensors
$ systemctl start hass_host_sensors
# show logs
$ journalctl -u hass_host_sensors.service
