Component supports: Argon ONE Raspberry Pi 4 Case, Argon ONE Raspberry Pi 3 Case, Argon Fan HAT.

1. Enable I2C. This is the most important step. Disabled I2C prevents the integraion from running and shows an error in logs.
   • Official way
   • Using Add-on HassOS I2C Configurator (the easiest way)
2. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
3. If you do not have a custom_components directory (folder) there, you need to create it.
4. In the custom_components directory (folder) create a new folder called argon40.
5. Download all the files from the custom_components/argon40/ directory (folder) in this repository.
6. Place the files you downloaded in the new directory (folder) you created.
7. Add argon40: to your configuration.yaml
8. Restart Home Assistant

Using your HA configuration directory (folder) as a starting point you should now also have this:

custom_components/argon40/__init__.py
custom_components/argon40/const.py
custom_components/argon40/manifest.json
custom_components/argon40/services.yaml

1. Add CPU Temperature sensor:

command_line:
  - sensor:
      name: CPU Temp
      unique_id: cpu_temp
      command: "cat /sys/class/thermal/thermal_zone0/temp"
      unit_of_measurement: "°C"
      value_template: "{{ value | multiply(0.001) | round(1) }}"

Or use System monitor integration to get the CPU temperature 2. Add automation:

automation:
  - alias: "Set fan speed"
    trigger:
      platform: numeric_state
      entity_id: sensor.cpu_temp
      above: 50.0
      for:
        minutes: 1
    action:
      - service: argon40.set_fan_speed
        data:
          speed: 40

automation:
  - alias: "Argon40 button double-tap"
    trigger:
      platform: event
      event_type: argon40_event
      event_data:
        action: double-tap
    action:
      - service: persistent_notification.create
        data:
          title: "Argon 40"
          message: "Button was double-tapped"
