ENV Variables

Environment variables are loaded from a .env file and validated using pydantic

More on Environment variables
  • ROOT_PASSWORD - System password to get the system vitals and run other sudo commands. Mandatory for Linux

  • TITLE - Title which Jarvis should address the user by. Defaults to sir

  • PLOT_MIC - Boolean value whether to show microphone usage in realtime. Defaults to True

  • LOG_RETENTION - Number of days to store the logs. Defaults to 10

  • WAKE_WORDS - List of wake words to initiate Jarvis' listener. Defaults to ['jarvis'] (Defaults to ['alexa'] in legacy macOS)
    :warning: Jarvis has limitations on the wake words as it relies on ML libraries for wake word detection.

  • VOICE_NAME - Name of the voice supported by the OperatingSystem. Defaults to the author's favorite.

  • VOICE_RATE - Speed/rate at which the text should be spoken. Defaults to the value from pyttsx3 module. Typically 200

    To add more voices


    • System Preferences → Accessibility → Spoken Content → System voice → Manage Voices...


    • Settings → Time & Language → Speech → Manage voices → Add voices
  • SENSITIVITY - Hot word detection sensitivity. Allowed range: [0-1] Defaults to 0.5

  • TIMEOUT - Timeout in seconds until which the listener should wait for speech. Defaults to 3

  • PHRASE_LIMIT - Timeout in seconds until which the listener will remain active. Defaults to None

  • LIMITED - Boolean flag to run only the main version of Jarvis skipping background processes. Defaults to False Enforced based on the number of CPU cores.

  • DEBUG - Boolean flag to enable debug level for logging. Defaults to False

  • RECOGNIZER_SETTINGS - A JSON object that has with customized speech recognition settings.

    Custom settings for speech recognition

    These are customized according to the author's voice pitch. Please use to figure out the suitable values on a trial and error basis.

    These settings are added (optionally), to avoid the hard coded PHRASE_LIMIT
    Cons in using hard coded PHRASE_LIMIT:

    • Disables the listener after the set limit even the speaker is actively talking.
    • Listener will be active until the set limit even after the speaker has stopped talking.

    Sample settings (formatted as JSON object)

    • RECOGNIZER_SETTINGS: '{"energy_threshold": 1100, "dynamic_energy_threshold": false, "pause_threshold": 2, "phrase_threshold": 0.1, "non_speaking_duration": 2}'

    • dynamic_energy_threshold: Change considerable audio energy threshold dynamically.
    • pause_threshold: Seconds of non-speaking audio before a phrase is considered complete.
    • phrase_threshold: Minimum seconds of speaking audio before it can be considered a phrase - values below this are ignored. This helps to filter out clicks and pops.
    • non_speaking_duration: Seconds of non-speaking audio to keep on both sides of the recording.


  • CAMERA_INDEX - Camera index that has to be used. Run to get the index value of each camera.
  • SPEAKER_INDEX - Speaker index that has to be used. Run to get the index value of each speaker.

Background Tasks

There are two options to run background tasks on Jarvis.

  • Jarvis can run internal tasks (offline communicator compatible) at certain intervals using a background_tasks.yaml file stored in fileio directory.

    Setup Instructions

    This is the sample content of background_tasks.yaml

    - seconds: 1_800
      task: just turn off all lights  # Runs every 30 minutes - 'just' flag retains the lights' last setting (eg: brightness or color)
    - seconds: 10_800
      task: remind me to drink water  # Runs every 3 hours ignoring the hours specified
       - 21
       - 22
       - 23
       - 0
       - 1
       - 2
       - 3
       - 4
       - 5
       - 6
  • CRONTAB - Runs external tasks using cron expressions. Needs to be stored as env var.

    Sample value
      "0 0 * * 1-5/2 find /var/log -delete",
      "0 5 * * 1 tar -zcf /var/backups/home.tgz /home/"


Jarvis can send on demand notifications using a contacts.yaml file stored in fileio directory. Uses gmail-connector for SMS and email notifications.

Setup Instructions

Note: Jarvis currently supports sending emails only when the contacts.yaml file is present, however phone numbers can be used directly.

  Tony: 0123456789
  Thor: 1234567890

Smart Devices

A source file smart_devices.yaml is used to store smart devices' hostnames. Jarvis supports MagicHome for lights, LGWebOS and Roku for TVs.

  • TV hostnames should include the brand name [LG/Roku] to distinguish the modules accordingly.

    • This will be set by default, if yours doesn't include the brand name change it in the TV settings.
  • To wake up Roku TVs using MAC address, make sure the Bandwidth saver feature is turned off under,

    Settings/Network/Bandwidth saver >> Off
  • For first time users on LGWebOS TVs, there will be a prompt on the TV to accept the connection request.

    • Once the connection request is accepted a client key will be generated and logged.
    • Please make sure to store this in smart_devices.yaml file to avoid repeated connection prompt.
Setup Instructions
  • TV identifiers should have the word tv to distinguish between lights and tv.
  • The name used in the keys (for both lights and tv) will be the identifier when an action is requested.
  • Lights should be a dictionary of identifier and a list of hostnames.
  • TVs should be a nested dictionary of multiple parameters.
  • The source file (smart_devices.yaml) should be as following:
hallway basement:
living room:
party mode:  # Light hostnames that needs to be engaged for party mode, if not present individual lights can be enabled
living room tv:
  hostname: 'HOSTNAME'
  client_key: 'CLIENT_KEY'  # Generated automatically if unavailable
  mac_address:  # Mac addresses can either be a string or a list
bedroom tv:
  hostname: 'HOSTNAME'
  mac_address: 'MAC_ADDRESS'

Automation Setup [Optional]

Jarvis can execute offline compatible tasks at pre-defined times without any user interaction. Uses an automation.yaml file as source which should be stored within the directory fileio

Setup Instructions

The YAML file should be a dictionary within a dictionary that looks like the below.

OPTIONAL: The key, day can be a list of days, or a str of a specific day or simply a str saying weekday or weekend when the particular automation should be executed.

Not having the key day will run the automation daily. Date format should match exactly as described below.

06:00 AM:
  day: weekday  # Runs only between Monday and Friday
  task: set my bedroom lights to 50%
06:30 AM:
  day:  # Runs only on Monday, Wednesday and Friday
  - Monday
  - wednesday
  task: set my bedroom lights to 100%
08:00 AM:  # Runs only on Saturday and Sunday
  day: weekend
  task: set my bedroom lights to 100%
09:00 PM:  # Runs daily
  task: set my bedroom lights to 5%
12:00 AM:  # Even performs tasks that are not supported via voice commands
  task: restart all background processes

Simulation Setup [Optional]

Jarvis can execute offline compatible tasks as a simulation to test the required functions and send an email with the results. Uses a simulation.yaml file as source which should be stored within the directory fileio

Setup Instructions

The YAML file should be a list of phrases within a dictionary that looks like the below.

- get me the events from my calendar
- what meetings do I have today
