🔱Modules Usage

These modules are not created using the autodiscovery, need manual setup or they need to be combined with others to work.

Statistics

It is used to send basic information of the app to gather daily usage per version.

The data is sent after 15 minutes of startup and then every 24 hours. Only some basic information is sent which includes UUID (a unique identifier that is generated and stored when first used) and the version of the app.

The server is a CloudFlare Worker that stores the data sent by the app including the date and the country the request originated from.

The statistics server is configurable under the configuration file of LNXlink, so you can use your own analytics server. By setting the URL to null or excluding the statistics module, you can disable it from sending any data.

Bash

The bash module can run any command on a remote computer which makes it dangerous, but also very helpful to create sensors without creating modules on LNXlink.

You will need to create a new sensor on your Home Assistant configuration file like so:

mqtt:
  sensor:
    - name: "Test ls"
      unique_id: "test_ls"
      state_topic: "lnxlink/desktop-linux/command_result/bash/bash_command/test_ls"
      availability:
        - topic: "lnxlink/desktop-linux/lwt"
          payload_available: "ON"
          payload_not_available: "OFF"

Then you must create an automation to run on an interval to get the result of a command:

alias: Get files count
mode: single
trigger:
  - platform: time_pattern
    seconds: "40"
action:
  - service: mqtt.publish
    data:
      topic: lnxlink/desktop-linux/commands/bash/bash_command/test_ls
      payload: ls ~/Downloads | wc -l

Voice Assistant

The Speech Recognition module listens to the user's input and sends the response as an attribute to the binary sensor of speech recognition entity.

For the automation to work you will need to setup the Media Player.

LNXlink Speech Recognition

Set the volume to the desired level and then if a successful speech is recognized it is sent to the conversation agent of Home Assistant to run. The result is then sent as an audio to the host machine.

alias: LNXlink Speech Recognition
mode: single
trigger:
  - platform: state
    entity_id:
      - binary_sensor.desktop_linux_speech_recognition
    from: "off"
    to: "on"
condition: []
action:
  - variables:
      volume: "{{ state_attr('media_player.desktop_linux', 'volume_level') }}"
  - service: media_player.volume_set
    data:
      volume_level: 0.15
    target:
      entity_id: media_player.desktop_linux
  - wait_for_trigger:
      - platform: state
        entity_id:
          - binary_sensor.desktop_linux_speech_recognition
        to: "off"
  - if:
      - condition: not
        conditions:
          - condition: state
            entity_id: binary_sensor.desktop_linux_speech_recognition
            attribute: speech
            state: "\"\""
    then:
      - service: conversation.process
        data:
          agent_id: homeassistant
          text: >-
            {{ state_attr('binary_sensor.desktop_linux_speech_recognition',
            'speech') }}
        response_variable: agent
  - service: media_player.volume_set
    data:
      volume_level: "{{ volume }}"
    target:
      entity_id: media_player.desktop_linux
  - service: tts.speak
    data:
      cache: true
      media_player_entity_id: media_player.desktop_linux
      message: "{{ agent.response.speech.plain.speech }}"
    target:
      entity_id: tts.piper

Notification

Sends a notification with an image as a preview

service: mqtt.publish
data:
  topic: {prefix}/{clientId}/commands/notify
  payload: >-
    { "title": "Notification Title",
      "message": "Testing notification",
      "iconUrl": "http://hass.local:8123/local/myimage.jpg" }

Turn PC On or Off

Combine with Wake on Lan to control your PC with one switch:

switch:
  - platform: template
    switches:
      my_pc:
        friendly_name: "My PC"
        unique_id: my_pc
        value_template: "{{ not is_state('button.shutdown', 'unavailable') }}"
        turn_on:
          service: switch.turn_on
          data:
            entity_id: switch.pc_wol
        turn_off:
          service: button.press
          data:
            entity_id: button.shutdown

Open a URL or File

service: mqtt.publish
data:
  topic: lnxlink/desktop-linux/commands/xdg_open
  payload: "https://www.google.com"  # or "myimg.jpeg" for file

Keys Send

Send a series of keys:

service: mqtt.publish
data:
  topic: {prefix}/{clientId}/commands/send_keys
  payload: "ctrl+f H e l l o space W o r l d"  

You can create a virtual keyboard on your frontend:

Install Update

When a new version of LNXlink is available the update sensor on Home Assistant activates the INSTALL button, but when you are using the development installation this option doesn't get activated. You can manually send the MQTT topic to start the update:

service: mqtt.publish
data:
  topic: lnxlink/desktop-linux/commands/update/update

Set unavailable after shutdown

Just before LNXlink stops, it sends to MQTT an OFF command, but sometimes it doesn't stop gracefully. To fix this, you will have to create an automation on Home Assistant which checks for when was the last time one of the sensors got a value and if it exceeds it sends the OFF command to the MQTT server.

This is an example of the automation which checks events for the idle sensor:

alias: lnxlink powered down
description: ""
mode: single
trigger:
  - platform: template
    value_template: >-
      {{ (now() | as_timestamp -
      states.sensor.desktop_linux_idle.last_changed | as_timestamp) >
      10 }}
condition: []
action:
  - service: mqtt.publish
    data:
      qos: 0
      retain: true
      topic: lnxlink/desktop-linux/lwt
      payload: "OFF"
